Abstract

The invention discloses a heavy oil engine exhaust system. The heavy oil engine exhaust system comprises a gas chamber assembly mounted at the bottom of an engine; the gas chamber assembly comprises apreheating gas chamber and through gas chambers located in the two sides of the preheating gas chamber; the through gas chambers are connected with an exhaust port of the engine; the bottoms of the through gas chambers are connected with through exhaust pipes correspondingly; the middle of the bottom face of the preheating gas chamber is connected with a main exhaust pipe; adjusting valves are mounted in the through gas chambers; when the rotating speed of the engine is lower than the set speed, an engine control system controls the adjusting valves to be opened towards the preheating gas chamber, and exhausted gas is exhausted through the preheating gas chamber and the main exhaust pipe; and when the rotating speed of the engine is higher than the set rotating speed, the engine control system controls the adjusting valves to be opened towards the through exhaust pipes, and the exhausted gas is directly exhausted through the through exhaust pipes. The torque at the low rotating speedis improved. When the engine is at the high rotating speed, smooth exhaust is ensured, the torque at the high rotating speed is improved, and the problem that the temperature of an exhausted and reheated cylinder head is too high is solved.

Description

technical field [0001] The present disclosure generally relates to the field of heavy fuel oil engines, and specifically relates to a heavy fuel oil engine exhaust system. Background technique [0002] In order to enhance the fuel atomization effect of heavy oil engines and improve combustion efficiency, the method of heating fuel oil with exhaust gas is now generally used. However, this method will cause the problem of overheating of the engine cylinder head temperature at high speeds, and the exhaust gas cannot be discharged well, so the torque in the high speed range will be affected. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an exhaust system for a heavy fuel oil engine that can exhaust reasonably. [0004] In the first aspect, the present application provides a heavy oil engine exhaust system, which includes an air chamber assembly installed at the bottom of the engine; the air...
