An Experimental Study on Combustion and Emission Analysis of Four Cylinder 4-Stroke Gasoline Engine Using Pure Hydrogen and LPG at Idle Condition. It occurs during the combustion process in the internal part of an engine. In a gasoline direct-injected engine, the injector nozzle protrudes into the combustion chamber. Four-stroke engines are the most common internal combustion engine used in automobiles, like trucks, cars, and some modern motorbikes (most motorbikes work with a two-stroke engine.) four-stroke is known as the combustion cycle. The gasoline direct injection is different from a conventional fuel injection in the location of the injector: In a conventional port fuel injection, the injector is installed in the intake port, above the intake valve. See the four-stroke diesel engine animation below. We chose a direct-injected engine because more than half of new cars with a gasoline engine have a direct injection. To illustrate, we created these two animations of a four-stroke direct-injected gasoline and diesel engines. The full combustion cycle consists of two revolutions of the crankshaft and four strokes: single working cycle (take-in, compression, energy and exhaust). An internal combustion engine is a four-stroke cycle motor which uses four separate piston strokes for a. In a four-stroke engine, each cylinder "fires" on every second revolution of the crankshaft. Each piston gets two kicks, in the following order, in a 4-stroke ICE. Four-stroke gasoline direct-injected engine animation. ![]()
