Fuel Saving Technologies
Transcript of Fuel Saving Technologies
Hydrogen can be extracted from methane which is cheap and plentiful. Water can also be a fuel source when you separate the hydrogen and oxygen by electrolysis. Before we can see more hydrogen cars on the road, hydrogen fuel cell technology must come down in price. This is a great fuel because it releases zero emissions in the area where it is being used. It depends if your electric fuel station has gotten its energy from solar power, wind or a power plant fueled by burning coal. Like hydrogen cars, all-electric are best suited for big city commuting, since most need frequent recharging and have range issues. That causes range anxiety for many consumers.
Improvements in battery technology should help fix the range problems. Even though there are more electric charging stations than hydrogen stations, they are still scarce and slow. It can take hours to recharge an electric car vs. a few minutes to refuel a gasoline powered car. Propane is a hydrocarbon gas similar to methane. It has two carbon atoms instead of one like in methane. One advantage of propane over methane is that it is widely available in most places. Propane is a popular fuel in drag racing too. Also propane is relatively clean burning like methane and does not release very many pollutants. Unfortunately, it is quite expensive. Ethanol Ethanol is mass produced in the U.S. from corn. In tropical regions it is made mainly from sugarcane. Most gas stations sell 10% ethanol infused into 90% gasoline. Some carry E-85, which is 85% ethanol and 15% gasoline, blended to work in specially modified engines. These cars are labeled "flex fuel" because they can run on 100% gasoline and any mixture of ethanol up to 85%. This is most popular in American automobiles. Your mileage will suffer on E85 compared to gasoline. Examples of Alternative Fuel Cars Electric, Tesla Model S, base price $52,300 Methane/Natural Gas Methane is a large percentage of natural gas. Methane is thought to be the cleanest burning hydrocarbon fuel known. Natural gas is a type of fossil fuel.
There are two different forms of natural gas you can use as fuel. One is CNG. That stands for compressed natural gas.
The second is LNG meaning liquified natural gas
Pros of Methane: there is lots of it, can be partly renewable and is inexpensive.
Con of Methane: it is collected by fracking, fueling stations are hard to find. Natural Gas Continued
Fracking and Collecting Methane Like all great fuels though, there is a problem. One of the main ways of getting natural gas is fracking. Fracking involves drilling miles deep into the earth and then sending tons of chemicals, water, and sand in at high preasure down into the rock. It is headed to a shale, or pocket of oil and gas deep in the earth. The chemicals crack the rock and go in. That releases the natural gas. After that the chemicals seep into underground water ways and eventually end up in drinking water. It also leaks into the atmosphere. Animals, plants and even people die from this. Is fracking worth it?
Another way that people collect methane is by capturing it when it is released from cow manure. Collecting it from land fills works too. This is one of the major future paths in fuel technology. All the chemicals in the water cause it to become flammable. http://www.dangersoffracking.com/ H20 This would be the ideal fuel for cars, if it worked. Many people say that water powered cars are possible, but there are none for sale. It is a controversial subject between the skeptics and people who think it works.
In my opinion it is impossible to get energy directly from water. It would be different if you are talking about dams that get power from water because then the cause would be gravity.
Many believe that the water powered cars in Japan are a conspiracy. There is no valid proof that they are water powered, due to them withholding information because of patenting reasons. Aerodynamics and Tires Under the bonnet Tires make a pretty large impact on fuel economy. The coarser the grade on the tire the more friction with the road. That friction is energy lost and it slows you down. The slicker the tire the better. That is true unless it is winter or you don't have enough grip.
Aerodynamics take a huge role in fuel economy because the bulkier the car, the more air that you have to push out of the way. That air is slowing you down and fighting the automobile. A streamlined body shape gives less resistance and in turn better mpg. Some cars like the Ford Focus have panels on the radiator that close according to the cooling needs of the engine. This makes the vehicle more aerodynamic. Also the faster you go the thicker the air seems to get and that is partly the reason why formula 1 cars are so low to the ground. It is a well known that the smaller the engine, better the gas mileage because it will use less fuel. The only problem with that is you lose power. That is why turbochargers are useful. They give the power of a larger engine to a smaller one. A turbocharger forces extra air and fuel into the intakes of the engine and basically increases the power. It saves weight and fuel. The only reason a person would not want one is that it puts more stress on the engine. That could cause engines to break. As long as the engine is relatively new I don't think it is a severe issue. These work on most internal combustion engines. Superchargers
Superchargers are just like turbochargers except they are belt driven and not fan. A bad thing about them is that they need to be running at 91 octane or higher to work well. That will cost more than regular at 87 octane. With these whether you save gasoline or not is up to you. Use the power to the max and drive like a maniac or take it slowly and calmly. Turbocharger Some other examples of fuel saving technologies are Honda's VCM. Variable cylinders management.This allows half of a cars cylinders and fuel injectors to stop when not needed. That reduces torque and horsepower but saves a lot of fuel. Just put the throttle down harder and it will return. Ford has eco boost that shuts off the entire engine off when your foot leaves the gas pedal.

These include gas/electric, flex fuel hybrids and diesel/electric. The Toyota Prius dominates hybrid sales for gas/electric hybrids. Hybrids make the most sense in big cities where there is stop and go traffic. They are quick and easy to refuel and there is no range anxiety. Hybrid cars currently are the most practical, high efficiency choice.
