Two stroke diesel and four stroke diesel engine is the same basic structure, the main difference in with gas institutions. Two stroke diesel no intake valve, some even the exhaust valve also have no, but in the open air cylinder and and vent; Or a carbon monoxide and exhaust valve and institutions. And set a driven by moving parts and air pump and storage of the air pressure and gas box, using the piston and the body to cooperate to complete with gas, which can simplify the structure of diesel engine. Figure is two stroke diesel working principle diagram. And in one side of the diesel engine with air pump, its rotor drive by diesel engine. Air from the pump suction inhaled, the compression back out, stored in with larger volume of the gas and in the box, and in it maintain a certain amount of pressure. Now that two stroke diesel in the work Principle. A, burning inflation and exhaust stroke: Fuel burning in the combustion chamber, high temperature and high pressure gas generated. The pistons in the push of fuel gas, the BDC downward motion, foreign doing work. The piston down until the vent open (right now crank in points, and gas inflation to do work at this time in the air over a large waste gas, on its own, high pressure free exhaust from vent queue of people to the exhaust. When in cylinder pressure drop to close to sweep gas pressure (general sweep gas box of the gas pressure and for 0-12, descending the piston engines and 3 open (righ
