Abstract

The invention belongs to the technical field of engine systems, and in particular relates to a regulating system, a vehicle and a method for controlling the opening of a bypass valve of the regulating system. The regulating system in the present invention comprises intercooler, engine, supercharger and bypass valve, and the air intake end of engine is connected with the air outlet end of intercooler, and the air inlet end of supercharger is connected with the air outlet end of engine , the first outlet of the supercharger is connected to the atmosphere, the second outlet of the supercharger is connected to the inlet of the intercooler, one end of the bypass valve is connected to the inlet of the supercharger, and the bypass The other end of the through valve communicates with the intake end of the intercooler. By using the adjustment system in the technical solution, the present invention bypasses the exhaust pipe at the front end of the turbocharger turbine and the supercharged intake pipe through the bypass valve to improve reliability and safety.

Description

technical field [0001] The invention belongs to the technical field of engine systems, and in particular relates to a regulating system, a vehicle and a method for controlling the opening degree of a bypass valve of the regulating system. Background technique [0002] Large-bore diesel engines are diesel engines with high power density and wide speed range. In order to adjust the boost pressure ratio in a wide range of operating conditions, the demand for successive turbocharging technology is derived. However, in the process of high-load operation, the exhaust temperature may be too high, which not only affects the performance of the after-treatment system at the exhaust end, but also damages the supercharger structure in severe cases. At the same time, when the load is reduced and the working supercharger is cut out transiently, the exhaust gas energy is absorbed and utilized by the still working supercharger, so that the boost pressure is significantly increased, which ma...
