Two-stroke diesel engine

Release time:2021-09-30 Reading:1173

A diesel engine that completes a working cycle through two strokes of the piston is called a two-stroke diesel engine. The oil engine completes a working cycle and the crankshaft makes only one revolution. Compared with a four-stroke diesel engine, it has improved working power. In terms of specific structure and working principle There are also big differences.

The basic structure of a two-stroke diesel engine is the same as that of a four-stroke diesel engine. The main difference lies in the valve train. Two-stroke diesel engines do not have an intake valve, and some do not even have an exhaust valve. Instead, a scavenging port and an exhaust port are provided in the lower part of the cylinder; or a scavenging port and exhaust valve mechanism are provided. A scavenging pump driven by a moving part and a scavenging tank for storing compressed air are specially set up, and the gas distribution is completed by the cooperation of the piston and the air port, thereby 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. Air is sucked in from the pump, compressed and discharged, stored in a scavenging tank with a larger volume, and maintained a certain pressure in it.

The fuel valve test device is an indispensable tool for testing the fuel valve of a diesel engine. Various fuel valve test devices can be selected according to different diesel engine models.
