The working principle of the engine is divided into 4 stroke parts?

Working principle of diesel engine: The working process of diesel engine is actually the same as that of a gasoline engine. Each working cycle also goes through four strokes of air intake, compression, work and exhaust.The diesel engine inhales pure air during the intake journey.

The four strokes are intake stroke, compression stroke, work stroke and exhaust stroke. Except for the work stroke, the other three are powerless output strokes, that is, ineffective strokes. The operation of the engine depends on the inertia of the flywheel and the working stroke of the engine.

The working principle of the four-stroke engine is to output power by transforming the up and down movement of the piston into the rotational movement of the crankshaft. The working process of a four-stroke engine is to convert the chemical energy of fuel into the mechanical energy of the piston reciprocate. The four strokes of a four-stroke engine are intake stroke, compression stroke, power stroke and exhaust stroke.

Exhaust stroke: The exhaust gas generated after the combustion of combustible mixed gas must be excluded from the cylinder in order to carry out the next working cycle.

How does the engine work?

The working principle of the engine is: electricity is provided by the storage battery. Under the control of the ignition switch and the start relay, the starter converts electrical energy into mechanical energy, drives the engine flywheel gear and crankshaft to rotate, and the start-up work can be cycled, so that the engine enters a self-operation state.

The working principle of automobile engines is mainly to convert chemical energy into mechanical energy. The reason why the engine has sufficient power is that it generates kinetic energy by burning the fuel in the cylinder, which makes the piston in the engine cylinder reciprocate, which is also a process of working cycle.

High-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a linear reciprocating movement, and the mechanical energy can be output outward through the connecting rod, crankshaft and flywheel mechanism. The four-stroke gasoline engine completes a working cycle in the intake stroke, compression stroke, workingstroke and exhauststroke.

What is the working principle and working process of a diesel engine?

In a working cycle of a diesel engine, only1 (work) stroke is driven by the piston to rotate the crankshaft, and the other 3 strokes are prepared for the work, and the piston movement needs to be driven by the crankshaft. The crankshaft of a single-cylinder diesel engine only rotates half a turn twice, so it will produce a large vibration, and the crankshaft rotation is unbalanced.

Working principle and process of diesel engine: The diesel engine generates high heat from the compressed air body, which explodes and expands after being sprayed into atomized diesel. The pressure acts directly on the piston, pushing the piston to make an unequal linear reciprocate movement along the cylinder.

The cylinder, cylinder head and piston form the combustion chamber, and the diesel is sprayed into the combustion chamber through the fuel injector and mixed with the air in the combustion chamber for combustion.
