How Gasoline Engines Work - Gasoline cars work on the same principals as all other cars i.e. hybrid, electric, and hydrogen. The major difference between them is the fuel that is used or burned in the engine and how many emissions are put out.
A gasoline engine burns fuel also called petrol. The fuel is pumped into the engine where it is then burned. The engine works on a four cycle principle. Cycle 1. the piston moves down the chamber drawing in the fuel, 2. the piston moves back up the chamber compressing the fuel, 3. the fuel is ignited by the spark plug and the piston is pushed back down the chamber in turn rotating the crank, 4. the piston then moves back up the chamber pushing the fumes from the burned fuel out of the engine and out of the car. The process of burning fuel for propulsion was engineered nearly 100 years ago which explains the crudeness and wastefulness of the process.
The piston is attached to a cam and a crank which operates the valves allowing the fuel to be let in and the exhaust to be let out. The crank is also the main shaft that drives the transmission and eventually the tires.
Hybrid cars put out very little emission's and get great fuel economy. As the gas prices continue to rise, hybrid cars will be more in demand and the use of fossil fuels will decline. Electric power is the way of the future and the only way to save our air.
