Yes they produce zero emissions. They also are cheaper to power.
Diesel cars do tend to cost more in general than gasoline engine cars. The claim on this is that it is more expensive to create and manufacture these vehicles, and due the fact that diesel vehicles are more fuel efficient.
A hybrid vehicle uses electricity and gas to power two engines, opposed to a single-engined, gas powered, "regular" car. A hybrid not only costs more up front, the weight and lack of horsepower compared to gasoline cars will probably make it less efficient and slow. Alternatives should be considered, such as EVs (electric vehicles), fuel-efficient gasoline cars, etc.
Diesel engines are more efficient than gasoline engines.
Because of a diesel engines high compression ratio, it will always be more efficient than an equivalent gasoline engine. However, this higher compression ratio requires a heavier, more expensive engine which isn't able to reach as high an RPM as a gasoline engine. It is for these reasons that despite their higher efficiencies, diesel engines are less popular than their lighter, less expensive gasoline equivalents. Diesel cars will provide you with a higher MPG rating compared to a similar gasoline powered engine. The price for diesel fuel is generally higher than the cost of unleaded gasoline.
The diesel is more efficient but more expensive to build.
While hybrids are more efficient than the standard vehicle, some hybrids are more energy efficient than others. All hybrids have an electrical engine that allows electricity to be used in times of need in order to support the gasoline engine thus using less gasoline. Many hybrids today have very high gas mileage and are very energy efficient. While some models get 40-60 miles per gallon, the Nissan Leaf gets 106 miles per gallon.
more efficient but more pollution
For a conventional gasoline engine, the higher the compression ratio, the more efficient the engine. US passenger cars have not had very high compression ratios for about 30 years for multiple reasons. During 1970-1972, Chrysler had the highest compression ratios in US production cars, requiring the highest octane gasoline to operate properly.
Yes because the use of oil is expelling CO2 into the atmosphere. Also Electric cars are quickly becoming more efficient then gasoline vehicles. As the standards for electric cars increase so is the innovation behind them. It is already cheaper and more energy efficient to drive an electric vehicle.
it was used to power steamships and electricity like lamps. it made lamps more efficient. it also powered cars but only 2% of cars
Electric cars are more efficient than gasoline cars. Plus, it's cheaper to generate electricity to charge a battery that will drive a car for 200 miles (typically about a dollar) than it is to buy gasoline to make a car go for about 200 miles (typically about 20 dollars). However, all the BS about eco-friendly is a bunch of hot air unless you're not getting your electricity from a coal fired or natural gas fired plant. You're just moving your emissions to another place on the planet, not eliminating them.
The source is Crude oil. Gasoline is extracted by heating cude oil and collecting the vapor at a specific temperature. The condensate is gasoline. The process is known as 'Cracking' and may have other chemicals added, to make the process more efficient.
