Working principle of single cylinder diesel engine

Release Date:


Diesel engine is an internal combustion engine that uses diesel fuel as fuel. It is a compression ignition engine and can be divided into single-cylinder and multi-cylinder diesel engines according to the number of cylinders. A single-cylinder diesel engine is a diesel engine with one cylinder. From the outside, there is only one injector and a high-pressure pipe. The coolant of the single-cylinder diesel engine does not circulate, but uses natural cooling. Its low-pressure oil intake relies on gravity, and it is more Compared to a diesel engine, there is no fine oil filter.

The single-cylinder engine is the simplest of all engines. It has only one cylinder and is the basic form of the engine. When a single-cylinder engine works, the piston reciprocates in the cylinder twice for each revolution of the crankshaft to complete a work program (two-stroke), or two circles of the piston reciprocates in the cylinder for four times to complete a work program (four-stroke) .

The mixture in the cylinder is ignited and burned once, and the explosive gas pushes the piston to rotate the crankshaft through the crankshaft connecting rod mechanism to realize the reciprocating linear motion of the piston in the cylinder. output to make the engine work normally
