2. The History of the Gas Engine
The Gasoline Engine is an engine ran on gasoline. It was created by entrepreneur Etienne Lenoir. It has been “reinvented” and upgraded throughout the last 150 years. Nikolaus Otto is one of the main developers and most successful engineers for the internal combustion engine. Before then all engines were powered by either steam or coal.
The History of the Gas Engine

3. Types of Gasoline Engines
There are several different versions of the gasoline engine such as the v8,6,10,12, and the inline 6, 8, etc. They are all different in size, efficiency, and power. The internal combustion engine is a very powerful and complex piece of machinery ran on a series of exploding pistons and moving belts. There are different sizes of an engine and the bigger they get the more harder the pistons explode causing more speed.

4. About the engine
“A petrol engine (known as a gasoline engine in American English) is an internal combustion engine with spark-ignition, designed to run on petrol (gasoline) and similar volatile fuels. The first practical petrol engine was built in in Germany by Nikolaus August Otto, although there had been earlier attempts by Étienne Lenoir, Siegfried Marcus, Julius Hock and George Brayton.[1] The first petrol combustion engine (one cylinder, cm3 displacement) was prototyped in 1882 in Italy by Enrico Bernardi. In most petrol engines, the fuel and air are usually pre-mixed before compression (although some modern petrol engines now use cylinder-direct petrol injection). The pre-mixing was formerly done in a carburetor, but now it is done by electronically controlled fuel injection, except in small engines where the cost/complication of electronics does not justify the added engine efficiency. The process differs from a diesel engine in the method of mixing the fuel and air, and in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed (and therefore heated), and the fuel is injected into very hot air at the end of the compression stroke, and self-ignites”.©

5. How An Engine Works
In a cylinder a fuel and air mixture is injected into the piston then it is compressed to a spark plug then explodes from the spark plug and shoots the piston to the bottom of the cylinder then comes back up and the exhaust is taken out of the cylinder by a pipe.
