Working principle of two-stroke diesel engine
Time of issue：
2022-10-18
The diesel engine that completes a working cycle through two strokes of the piston is called a two-stroke diesel engine. The crankshaft of the oil engine only rotates one circle to complete a working cycle. Compared with the four stroke diesel engine, it improves the work ability, and there are also great differences in the specific structure and working principle.
Two stroke diesel engine and four stroke diesel engine have the same basic structure, but the main difference lies in the valve train. Two stroke diesel engines do not have inlet valves or even exhaust valves. Instead, scavenging ports and exhaust ports are set at the lower part of the cylinder; Or set scavenging port and exhaust valve mechanism. A scavenging pump driven by moving parts and a scavenging box for storing pressure air are specially set, and the piston and air port are used to complete the gas distribution, thus simplifying the structure of the diesel engine. The figure shows the working principle of a two-stroke diesel engine. The scavenging pump is attached to one side of the diesel engine, and its rotor is driven by the diesel engine. The air is sucked in from the pump, compressed and discharged, and stored in the scavenging box with large volume, where the pressure is maintained.
