Common vehicle engines have many classifications depending on the type, size and use.
A, according to the work cycle:
1. Otto cycle: used in gasoline engines.
2, Diesel cycle: used in diesel engines.
B. Depending on the type of fuel used:
1. Gasoline engine: mainly used in automobiles and aircraft.
2, diesel engine: mainly used in cars, boats, generators.
3. Heavy oil engine: mainly used in ships and generators.
4, gas engine: mainly used in cars.
C, according to the cooling method:
1. Air-cooled engine
2, water-cooled engine
D, according to the work cycle stroke points:
1. Two-stroke engine: Two strokes complete one working cycle.
2. Four-stroke engine: Four strokes complete one working cycle.
E, depending on the piston movement:
1. Reciprocating piston engine
2, rotary piston engine
F, according to the ignition method:
1. Compression ignition engine
2, spark plug ignition engine
G, according to the number of cylinders:
1. Single cylinder engine
2, multi-cylinder engine
H, according to the arrangement of the cylinders:
1. In-line engine
2, V-type engine
3, W type engine
4, horizontally opposed engine
The Danfoss Motor said: The engines used in current automotive products are mainly Otto cycle, gasoline-fueled reciprocating piston four-stroke multi-cylinder natural intake engines, depending on the displacement and engineering requirements. In-line four-cylinder, V-shaped six-cylinder and other forms. The parts used in the various types of engines, as well as the minor system components on the outside of the engine, are very similar.
