Transcript of 4 Stroke Engine

The car has been a revolutionary part in our culture and will be for years to come. The car only ever started with the invention of the engine. The engine was sweeping achievement in technology with two different types of engine the two stroke and the four stroke. The difference between these two engines are the simpler design and louder engine on the two stroke engine whereas the four stroke engine is more economical and better for a longer duration. The first person to build a working four stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines. The Diesel cycle is the thermodynamic cycle which approximates the pressure and volume of the combustion chamber of the Diesel engine, invented by Rudolph Diesel in 1897. It is assumed to have constant pressure during the first part of the "combustion" phase. The idealized Otto cycle of a gasoline engine approximates constant volume during that phase, generating more of a spike in a p-V diagram. Advantages and Disadvantages How It Works Simple Machines Input/Output History Components The 4 Stroke Engine has many inputs. It can have electricity, manual labor, or the most common, gasoline. The gasoline is put into the combustion chamber, and then ignited, which then pushes the piston down. The piston turns the crank shaft as it gets pushed down again and again by the gasoline being ignited and blasted. The turning crank shaft then in turn produces the mechanical energy either to move the vehicle, or to produce electricity by moving a generator. But, the mechanical energy is not the only out put 4 stroke engine has. It also produces green house gases such as carbon monoxide, carbon dioxide, etc. when it burns down the gasoline. 4 Stroke Cycle 2 Stroke Cycle 4 STROKE ENGINE Lever
