Problems solved by technology

This setting makes the impulsive kinetic energy of the engine exhaust unable to be utilized, and also leads to excessive exhaust back pressure affecting the smoothness of the exhaust.
When the engine cylinder exhaust comes to an end, if the exhaust back pressure in the exhaust valve chamber is large, the exhaust will not be complete, which will affect the engine's supercharging and combustion effects, and affect the engine's power

Abstract

Disclosed is an internal supercharger engine which comprises an engine (1), exhaust valve chambers (2), exhaust turbines (3), an exhaust channel (4), a power turbine (5) and an air inlet channel (6); the exhaust turbines (3) are respectively arranged in each exhaust valve chamber (2); the rotational shafts of the plural exhaust turbines (3) are connected together and connected with the rotationalshaft of the power turbine (5). The internal supercharger engine has the advantages of high supercharging efficiency, fast response in turbine supercharging, small exhaust noise and small back pressure, complete waste gas exhaust, improving the engine efficiency and the low-exhaust property.

Description

technical field [0001] The invention relates to the field of engines. technical background [0002] The turbocharging system that is widely used now is to push the exhaust turbine after summarizing the exhaust passages of a plurality of cylinders, and the exhaust turbine is located on the exhaust passage far away from the exhaust valve chamber. This setting makes the impulsive kinetic energy of the engine exhaust unable to be utilized, and also causes excessive exhaust back pressure to affect the smoothness of the exhaust. When the engine cylinder exhaust comes to an end, if the exhaust back pressure in the exhaust valve chamber is large, it will lead to incomplete exhaust, which will affect the supercharging and combustion effect of the engine, and affect the power of the engine. In order to make more effective use of the pulse kinetic energy of the engine exhaust, and to greatly reduce the pressure in the valve chamber at the end of the exhaust stage of the engine cylinde...
