Four Stroke Engine How it Works

dsl- 4 stroke diesel engine.flv Four-stroke engine Four-stroke cycle used in gasoline/petrol engines. 1 - Intake, 2 - Compression, 3 - Power, 4 - Exhaust. The right blue side is the intake and the left brown side is the exhaust. The cylinder wall is a thin sleeve surrounded by cooling liquid. A four-stroke engine (also known as four-cycle) is an internal combustion engine in which the piston completes four separate strokes which comprise a single thermodynamic cycle. A stroke refers to the full travel of the piston along the cylinder, in either direction. While risqué slang among some automotive enthusiasts names these respectively the "suck," "squeeze," "bang" and "blow" strokes.[1] they are more commonly termed

Nikolaus Otto was an German inventor of the first interna... Nikolaus Otto was a German whom invented the first internal combustion engine which burnt fuel efficiently in a piston combustion chamber. He lived for 58 years, he was born on 10th of June 1832 in western Germany and died on 26th of January 1891 in Cologne Germany. Intake stroke - The piston descends from TDC (top dead center) to BDC (bottom dead center). As soon as the piston starts to descend, the inlet valve will open and a mixture of fuel and air or just air in diesel engine is forced in to the cylinder by atmospheric pressure.

Wankel Engine I've recently found out about a Wankel Engine, much more sensible engine design then the usual engines we are used to. This is something most people are unaware of. Most of us are used to common 4-stroke cylinder engines found in most today's cars. Combustion Chambers (and a little engine theory) The combustion chamber is the area inside the engine where the fuel/air mixture is compressed and then ignited. It is generally formed on one side by the shape cast into the cylinder head, and on the other side by the top of the piston. When the piston is at top-dead-center the chamber is at its smallest dimension, and this is the time when the fuel/air mixture is at its most unstable condition and ready to be ignited. The better the combustion chamber is designed the better the engine "breathes;" that is, the more efficient the overall flow of air through the engine. The engine's overall efficiency is determined by the shape of the chamber, shape of the top of the piston, location of valves and spark plug and overall airflow through the intake and exhaust.
