Problems solved by technology

[0004] The engine air intake system with a turbocharger, because the turbocharger has the disadvantage of hysteresis, that is, due to the inertia of the impeller, the response to the sudden change of the throttle is slow, and when the engine starts or the vehicle accelerates, the air entering the engine combustion chamber The flow rate of the engine increases slowly, and the amount of air entering the combustion chamber of the engine increases less when the fuel injection volume increases, which in turn delays the increase in the output power of the engine. Slow; at the same time, when the engine is started or the vehicle is accelerating, due to the increase of the fuel injection volume and the insufficient intake air volume, the fuel combustion is insufficient, resulting in a large amount of particle emissions, and the fuel consumption is large

Abstract

The invention relates to the technical field of engines and discloses an air inlet system for an engine, which comprises a turbo charger, an engine air inlet and an air amplifier, wherein a low-pressure air inlet of the air amplifier is connected with an air outlet of a compressor of the turbo charger, an air outlet of the air amplifier is communicated with an air inlet of an engine, and a high-pressure air inlet of the air amplifier is communicated with a high-pressure air source. When the engine starts or a vehicle accelerates, the air inlet speed of the air inlet system for the engine is higher.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine air intake system with fast air intake speed when the engine is started or the vehicle is accelerated. Background technique [0002] At present, the intake and exhaust systems of engines, especially diesel engines, generally adopt turbocharging to improve the power of the engines. Turbocharging is to compress air in advance and then inject it into the cylinder of the engine. Turbocharging is usually achieved through a turbocharger. [0003] A turbocharger usually includes a compressor and a turbine. The compressor is mechanically connected to the turbine. The compressor is arranged on the intake pipe of the engine. The outlet of the compressor communicates with the inlet of the engine. The turbine is arranged on the exhaust pipe of the engine. , the air inlet of the turbine is connected with the air outlet of the engine. When the engine is running, the exhaust gas disc...
