Abstract

The invention discloses a pulse type exhaust turbocharging system for a gas diesel engine. The pulse type exhaust turbocharging system comprises exhaust ports and exhaust pipes. The exhaust ports are connected with an internal combustion engine exhaust duct and the exhaust pipes. Outlets of the exhaust pipes are directly connected with a turbine. The exhaust pipes are short and thin, pulse energy can be fully utilized, the air inlet pressure of the engine is high, and the engine performance of the engine is excellent. The adjacent exhaust pipes on the working condition are separated, so that exhaust disturbance is reduced, and air scavenging can be completed easily. The pulse type exhaust turbocharging system has the advantages of being reasonable in design, simple in structure, small in size and applicable to the turbine provided with one inlet.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, and more specifically relates to a pulse type exhaust turbocharging system for a gas diesel engine. Background technique [0002] In the field of internal combustion engines, the exhaust temperature and pressure indicate that the exhaust gas has a lot of energy, and how to effectively use the exhaust energy has long been an important topic for researchers to study. In order to improve the thermal efficiency of internal combustion engines, reduce the emissions of internal combustion engines, and thereby reduce the production cost per unit power, researchers have widely used internal combustion engine supercharging technology. The two basic types of turbocharging systems are constant pressure supercharging system and pulse supercharging system. At present, the constant pressure supercharging system is commonly used. It is relatively simple. The pressure in the exhaust pipe is b...
