Supercharged inter-cooling internal combustion engine gas intake bypass control device

Abstract

The invention discloses a supercharged inter-cooling internal combustion engine gas intake bypass control device. The supercharged inter-cooling internal combustion engine gas intake bypass control device comprises an air filter (1), an equal-diameter three-way pipe (2), a loop pipe assembly (3), a gas compressor (4), an intercooler (5), a voltage stabilization cavity (6), a throttle valve (7) and an internal combustion engine air cylinder channel pipe (8). The equal-diameter three-way pipe (2), the loop pipe assembly (3), the gas compressor (4), the intercooler (5), the voltage stabilization cavity (6), the throttle valve (7) and the internal combustion engine air cylinder channel pipe (8) are sequentially connected with the air filter (1). A circulating pipe (9) is connected between the loop pipe assembly (3) and the voltage stabilization cavity (6) and provided with a bypass valve (10). The supercharged inter-cooling internal combustion engine gas intake bypass control device has the beneficial effects that the device structure is simple, and the installation cost is low; transformation is conducted under the condition that mechanical components of an internal combustion engine set are not changed, and the controllable variation range of gas inflow is large; the application range is wide, the fitness is high, and the phenomenon of unstable running is avoided.

Description

technical field The invention relates to the field of intake control of combustible mixtures of internal combustion engines, in particular to an intake bypass control device for supercharged and intercooled internal combustion engines. Background technique The control of the combustible mixture of internal combustion engines is particularly important in the field of internal combustion engines. At present, exhaust gas turbocharging is the most effective and common supercharging method in supercharged internal combustion engines. Due to the small variation range of the rated flow rate of exhaust gas turbocharging, the same turbocharger causes Poor environmental adaptability, when operating in different environments, the efficiency of the supercharger varies greatly. When the environmental altitude changes greatly, the turbocharger must be re-matched to meet the operating requirements of the unit; when the waste gas bypass control system is used, due to the high temperature o...
