Electric valve turbocharger

Abstract

The invention relates to an electronically controlled valve turbocharger, comprising a turbine, an intermediate body and a compressor box. The left and right ends of the intermediate body are respectively provided with a turbine and a compressor box; the turbine and the compressor box are respectively equipped with a turbine and a compressor box. The intake impeller, the turbine and the intake impeller are connected to each other through a rotating shaft in the intermediate body, the turbine and the compressor box are respectively provided with an exhaust pipe and an intake pipe, and the exhaust pipe and the intake pipe are connected to the engine. After adopting the above structure, compared with the prior art, the electronically controlled valve turbocharger of the present invention adopts the electronically controlled valve to control the air pump to transmit an appropriate amount of gas to the intermediate, thereby ensuring that the intermediate is connected to the turbine and the compressor. The air pressure between the tanks is kept stable, preventing the oil sprayed from the oil tank from overflowing into the turbine and the compressor tank, or the gas in the turbine and the compressor tank entering the intermediate body.

Description

technical field [0001] The invention relates to the field of engines, in particular to an electronically controlled valve turbocharger. Background technique [0002] In the field of vehicle engines, exhaust gas turbochargers have been widely used. The principle is: use the energy in the exhaust gas from the engine to drive the turbine to rotate, and drive the coaxial compressor to rotate to compress the air entering the engine. In order to increase the air intake density of the engine, the purpose of increasing engine power, optimizing combustion and reducing emissions is achieved. Because turbocharging can improve power, reduce fuel consumption, and reduce emissions, turbochargers have become an indispensable key component of today's advanced engines. However, since turbochargers are rotary impeller machines, their matching with reciprocating engines It is more complicated, and because the working state of the vehicle engine changes frequently and the working area is wide,...
