GASOLINE ENGINES are used to do all kinds of stuff. Gasoline engines are used to power things in sizes from that of a weed chopper to that of a muscle car. All of these engines are based on the same principle. GASOLINE ENGINES run on the principle of the power and exhaust strokes. These are the most impressive and most used engines in the world. Gasoline engines power performance sports cars like the one below. This is the picture of a 350 cubic inch chevy engine that powers a corvette. This is one of the fastest cars in the United States. This is a 5.7 liter engine. In gasoline engines performance is measured in liters. Liters are the amount of area available for combustion.

4 STROKE GASOLINE ENGINES run on the principle of exhaust and power strokes. Air is taken in the front of an engine. Air is then filtered and moves toward the combustion chamber. Air mixes with fuel and is injected to the combustion chamber. This air is compressed and then a spark plug fires. The piston then moves downward rotating the crankshaft. The exhaust ports open letting the burned fuel out. This is a simple process and is used in 4 stroke engines. |

2 STROKE GASOLINE ENGINES run on the same principle as the 4 stroke engine, but the 4 strokes are transformed into 2 simpler strokes in this engine. The air mixes with the fuel and is burned as the piston moves down exhaust is allowed out, and new fuel comes in during the same step. This allows some fuel out of the engine, releasing hydrocarbons and stuff in the air. The United States frowns on these emissions so two stroke engines aren't widely used. These engines are used in mainly smaller applications. The most major drawback is the use of 2 stroke pre-mix that must be mixed in the fuel. |
