Every American is demanding for vehicles with the ability to improve its efficiency as well as increase its gas mileage, especially with the rising of gas prices. The invention of hybrid vehicles is an ultimate answer or such demand.

A hybrid vehicle is a vehicle that is combining two forms of power sources as its generator. A research on hybrid gas mileage is being done continuously to get the best result. Many car manufacturers develop newer and newest design of hybrid vehicles with excellent hybrid gas mileage. Toyota Prius has become the best hybrid gas mileage now. But the developing technology on hybrid vehicles, there might be a replacement in the near future.

hybrid gas mileage

Recently the ratings of hybrid gas mileage looks like impressing compared to the majority of conventional vehicles on the current market. However, there is still a lot more things to do. This is quite significant upon studying hybrid gas mileage’s historical chart.

Car manufacturer promises that a hybrid car will only had 100 mile per gallon (MPG). Such number is achievable now with such technology we have today. This will lessen our dependant on petroleum derivatives. Moreover, we are actively involved in keeping our world green for our future and also for our descendants.

In 1970s, the actual amount of miles driven has rising significantly since the oil crisis, when the US made admiral movement in reducing carbon emissions in general. Until the 1990s, that is-that’s when they in progress to rise again. Meanwhile, automakers continued to prevent attempts to raise fuel efficiency values. Thus, from the late 80s onward, miles driven increased and fuel efficiency dropped. The result? The problem of carbon emissions increased.

It’s a ‘toxic combo’—more and larger vehicles with higher amounts of miles driven partnered with reduced fuel efficiency—one that equals an increasing of the carbon emissions burden.

But don’t worry. While we cannot surrender our pleasure and dependence of our vehicles, as an individual you can take action to reduce your vehicle’s greenhouse gases, as well to helping to reduce dependence upon imported oil, save your wallet and cleaning the atmosphere we all breathe. Sound good? Very good. Keep reading this information to help make it happen:

1. Go Green: Learn about green vehicle fuels and use these alternative fuel vehicles. Or you can check out the fuel economy and emission information of your vehicle. Begin with the Fuel Economy Guide and Green Vehicle Guide to see how your 4-wheels shape up. Check if you have a FFV or flex fuel vehicle—with over five million flex fuel vehicles on the road recently—your vehicle might just be a ‘FFV sleeper’. Is yours on this list?
2. Go Easy & Maintain . . .: There are many factors shape your vehicle’s fuel economy—and one of the most important is a regular maintenance and easy driving habit. If you use a lighter foot on the gas pedal and brakes, avoid putting the pedal to the metal for rapid accelerations, and lessen idling time, fuel economy of your vehicle will get better and reduce greenhouse effect. The correct of tire pressure will also help in fuel economy.
3. Buddy up: Whether you desire to carpool with your friends, grab the bus, jump on your bike or locomote with your legs, they’re all habits to put your car parked in the garage-and reduce your contribution to the carbon emissions. Let your car in garage and choosing one of these alternatives just two or three times per week, and you can cut 1,590 pounds gas emissions in a year.
4. Plan first: When heading out to ensure of errands, try to combine your trips. When your car’s engine is cold, its consume twice as much fuel in addition to producing double as many gas emissions. So, try to combine your short trips with multipurpose trip with a warm engine and you’ll not only save time, but also your money and reduce your contribution to the carbon emissions.

This consumer awareness program was met with ‘cynicism’ by environmentalists, who emphasize that the campaign throws a smoke screen over the industry’s slow move toward fuel-saving vehicles. In an interview with hybridcars.com, Jim Kleisch, senior engineer with the Union of Concerned Scientists said, “Providing drivers tips on how to improve their fuel economy is helpful, but the industry needs to be doing a lot more than this. Consumers need cleaner and substantially more fuel-efficient vehicles on the showroom floors and until that happen, our economy and our environment are going to suffer.”

The ‘Eco Driving’ program teaches each American driver a set of best practices for driving and maintenance, allowing a typical car owner to ‘augment’ fuel economy about 15 percent. Driving and operation practices consist of: driving at optimum speeds, making the best use of synchronized traffic lights, utilizing proper braking techniques, and deciding when it makes sense to use air conditioning. On the maintenance side, the guidance tackles issues such as choosing which motor oil to use, as well as knowledge the effects of tire pressure.

Much of the information provided is ‘familiar’ sense. The idea is for motorists to start decrease their carbon footprint ASAP without having to purchase a new fuel-efficient vehicle, or wait years on the development of advance technology.

But I’ll give some tips and guides, skip buying a new car-save your money-but you can reduce carbon emissions.

Here are four things you can do to reduce carbon emissions which cost a heck of a lot less than buying the most fuel efficient car out there right now, the Toyota Prius.

1. Reduce Carbon Emissions with Switch To Green Power

Green power program is the greatest thing you can do to reduce carbon emissions. Generally, it takes only a few minutes to enroll and costs a few cents more per kilowatt hour. So, when you switching to green power you can reduce carbon emissions about 14,000 pounds (compare with switching to Prius – 5,000 pounds), and it costs just $200 per year.

2. Reduce Carbon Emissions with Eat More Local Food

You need a lot of carbon emissions to distribute your meal from where they were grown to get to your plate (Average United State meal travel about 1,200 miles). But, when you decide to eat more local food, you can reduce carbon emissions about 8,000 pounds and save more than 1.5 times the emission savings of buying a most fuel efficient car. Moreover, with this small a change in spending patterns, will be minimal your monthly budget (some local food may cost more than imported ones while others may be less expensive.)

3. Reduce Carbon Emissions with Simple Steps Do Add Up

There are many ways to reduce carbon emissions. From buying most fuel efficient car, eat more local food, or with green power program. And now, there are simple steps we can do in terms of reducing carbon emissions.

Here some tips and guides you can do to reduce carbon emission (about 5,350 pounds carbon emissions) and save the same amount as buying the most fuel efficient car (cost of under $300 for the year)

• Three days a week take carpool or public transit to work.

• Keep the tires on your car properly inflated.

• Wash your clothes in cold water and then air dry all of them, all the time.

• Install ten compact fluorescent lightbulbs to replace incandescent bulbs.

• Turn down your water heater to 120 degrees.

• Properly insulate your water heater.

4. Reduce Carbon Emissions with Adopt a Vegetarian Diet

Vegetarian habit has great benefits in terms of reducing carbon emissions. When you decide to adopt a vegetarian diet you can avoid the emissions of a bit more than 5,000 pounds of carbon emissions per year. Beside that, you can save about 20% on your monthly food costs.

You’ve almost certainly heard the phrase “carbon emissions”, “global warming”, and “climate change” in the same breath, and most everybody has at least a pretty basic idea about where they come from.

And now let us give a little time at this ubiquitous term for these ubiquitous emissions.

Carbon emissions: The basic

Carbon emissions is come from burning fossil fuels which contributes to global warming. Each time when you turn on your car, watching television, travel to work or shopping, clothes washing or board an airplane, you are producing carbon emissions.

Technically, carbon emissions should be called carbon dioxide emissions or you shortened it, carbon emissions = carbon dioxide emissions = contribution to global warming.

Carbon emissions: Who cares?

Who cares about carbon emissions? Carbon dioxide creates the largest contribution to the greenhouse effect, which is what is slowly, yet persistenly, warming our globe. That makes it the most important greenhouse gas out there; it’s currently responsible for about 10 – 25 percent of the greenhouse effect. The next two on the list is methane and ozone, incidentally, do not crack the double digits, so carbon emissions are in the lead, in a bad way, when it comes to greenhouse gas emissions.

All this is to say, really, that we live not only in a carbon-based world, but a carbon emission-based society and economy, and the scope of activities that produce carbon emissions is just huge. Anything involving coal, natural gas, petroleum has a carbon emission ticket attached; that includes all transportation and a whole lot of home heating systems and even barbeques, just as a small snapshot.

Carbon emissions: The science

Here’s a quick tour of the science of carbon emissions. Fossil fuels have ultimately been created of fossil aged feedstocks (think dinosaurs) have been throughout millions of years of Earth’s cycles, and now discover themselves under oceans, in the ground, and other places not often directly in our backyards.They’ve had a long time to “stew,” for lack of a better word, and have a high concentration of energy, which is why someone a few hundred years ago had the idea to use them for fuel.

So, these super-old, carbon-based, previous dinosaurs are dug up and, in one way or another, lit on fire. They have high concentrations of carbon, which, when mixed with oxygen through combustion, create carbon dioxide (or CO2). So, what was formerly interred in the Earth’s crust is now out, and the carbon that was sequestered with it comes, too.

Carbon emissions: Beyond fossil fuels

So carbon emissions are created when we burn fossil fuels, but that’s not the whole story. Activities that are often less prescient to many of us on a day-to-day basis have huge emissions, too. Land use changes – mainly deforestation in the Amazon, Borneo and many other tropic areas – account for almost 10 percent of global greenhouse gases. It’s sort of a matter of addition by subtraction; more carbon emissions stay in the atmosphere as deforestation occurs, since trees and other plant life absorb carbon dioxide as they grow.

Livestock are also becoming a larger player in greenhouse gas consideration; though they tend to supply more methane than anything, they still merit mention here. How do cows play in to this, you ask? Two words: Enteric fermentation. This is the process like cows that takes place in the digestive systems of ruminants; without getting too deep into the microbiology behind it (you can learn more from Wikipedia), basically, it results in an excess of methane being debarred from the animal. That’s right: Cow burps and farts, as well as the decomposition of their poo, are serious contributors to greenhouse gases. Agricultural by products essentially account for more than 10 percent of all greenhouse gas emissions — and that’s more than results from residential sources.

Carbon emissions: Reducing

Finally, how to reduce your carbon emissions? As an Americans your carbon footprint – the measurement used to estimate your personal carbon emissions – is about 20 tons. If you want to cut that number in half, follow my next posting about how to reduce carbon emissions and you will have lost 10 tons in what seems like no time flat.

Emissions from diesel and gas engines contribute to serious public health problems not just in the U.S. but of the world. These problems include premature mortality, aggravation of respiratory and cardiovascular disease, aggravation of existing asthma, acute respiratory symptoms, chronic bronchitis, and decreased lung function. Numerous studies also link diesel exhaust to increased incidence of lung cancer.

gas emissions's effect

For example, on-road diesel-fueled vehicles contribute approximately 27 percent of the NOx emission inventory and 62.5 percent of the PM emissions. An older, dirtier diesel vehicle can emit almost 8 tons of pollution per year. This amounts to 160 to 240 tons of pollution over the life of the engine. A heavy-duty truck can create the same amount of air pollution as 150 passenger cars.

For these reason, each State has its own set of emissions standards. The European Union has its own set of emissions standards that all new vehicles must meet. Currently, standards are set for all road vehicles, trains, barges and ‘nonroad mobile machinery’ (such as tractors). No standards apply to seagoing ships or airplanes. The emissions standards change based on the test cycle used: ECE R49 (old) and ESC (European Steady Cycle, since 2000).

In the United States, emissions standards are managed by the Environmental Protection Agency (EPA). The state of California has special dispensation to promulgate more stringent vehicle emissions standards, and other states may choose to follow either the national or California standards.

In the Japan, The amended rule is called the “Law Concerning Special Measures to Reduce the Total Amount of Nitrogen Oxides and Particulate Matter Emitted from Motor Vehicles in Specified Areas”, or in short the Automotive NOx and PM Law

The Solutions

Vehicles are very important tools for transportation, but they have harmful effects on the environment and health. Fortunately other power sources and fuels are being developed to serve as an alternative.

And now, more and more people are becoming aware of how much mankind has affected the planet. The need for solutions is recognized more than ever to address environmental issues. Due to this hybrid cars are becoming increasingly popular to consumers.

Hybrid vehicles work by using an internal combustion engine which uses fuel and a rechargeable energy storage system. By using the combination of these two power source the vehicle will be able decrease fuel consumption, reduce pollution and leads to lesser emissions.

Hybrid Emissions

The engines in vehicles is a rather broad but interesting subject. People may be amazed to know that the ones currently in use today were drawn on several hundreds of blueprints before they were distributed to the market. The present models are the result of over a century worth of brainstorming and experience and will further influence the models of the future.

What is the ICE?

ICE stands for Internal Combustion Engine wherein the combustion of fuel and an oxidizer occurs. The combustion chamber is the space where everything happens causing an exothermic reaction that produces gas at a high pressure and temperature. The expanding hot gases will directly put pressure on solid engine parts causing them to move. Pistons, rotors or the engine itself then begins movement which propels the entire vehicle.

The very first models of the ICE ran on an air/fuel mixture rather than compression. The initial part of the intake stroke sucks or blows in the mixture. Modern ICEs already incorporates in-cylinder compression. The engines were used in a variety of methods and industries like generators, boats, aircrafts and most particularly, automobiles.

The Operation

The internal combustion engine operates using a four-stroke cycle or the Otto cycle. The cycle involves four phases namely: induction, compression, power and exhaust. All of these aim to create an exothermic chemical process to start vehicle propulsion. During induction, oxygen or other oxidizers are introduced into the cylinder to act with the fuel. Compression then begins as the gases start a reaction that continuously increase temperature and pressure within the cylinder.

When enough pressure is applied on the corresponding engine parts, the engine begins to gain power through movement coming from direct force application. The aftermath of the entire compression process will lead to exhaustion of by products like carbon monoxide, carbon dioxide and nitrogen wastes. These gases are freely emitted into the atmosphere. The combustion process is started through engine ignition using the spark ignition method or the compression ignition system.

Where Does Gasoline Come In?

There are electric/gasoline-type systems that use a combination of lead-acid battery plus an induction coil to create a high-voltage electrical spark. The spark will then ignite the mix of air and fuel within the cylinder. The battery is rechargeable even during operation through an alternator or generator driven by the engine itself. Gasoline engines get an air and gasoline mixture to be compressed to less than 185 psi. The spark plug ignites the mixture during compression within the cylinder.

As for diesel engines, these require only heat and pressure produced by the engine during the compression process for ignition. Diesel compression is approximately three times higher compared to a gasoline engine. Diesel engines use air only. Some diesel fuel is sprayed into the cylinder with the use of a fuel injector just before peak compression to start ignition immediately. HCCI engines also require only heat and pressure but take in air and fuel. This process makes diesel and HCCI engines more prone to cold starts.

The Polluting Effects

Combustion products or the hot gases ignited and burnt inside the engine will have higher amounts of energy compared to the compressed fuel and air mixture. After available energy are used up to drive the engine pistons, remaining combustion products will be vented or exhausted through a valve or the exhaust outlet to bring back the piston in its original state also called TDC. Any heat which is not used up will become a waste product due to be removed from the engine via a liquid or air cooling system.

Air pollution emissions then result from incomplete combustion of carbonaceous fuel. Examples of engine byproducts are carbon monoxide, soot, nitrogen wastes, sulfur and uncombusted hydrocarbons. These also result if the products did not operate near the stoichiometric ratio required for effective combustion. The fuel would not have burnt very well due to factors like cool cylinder walls or lack of air. This is also known as quenching of the flame.

Both gasoline and diesel engines emit harmful gases that can be dangerous to humans as well as the environment. The greenhouse gases start trapping hot air within the atmosphere instead of allowing them to exit to space leading to global warming. The rise of the ICE or internal combustion engine finally showed its major flaw which is pollution.
