Abstract

The invention provides a controllable built-in electromagnetic waste gas bypass turbocharger which comprises a turbine box, an end cover fixed to the turbine box and a bypass mechanism arranged in the turbine box, the bypass mechanism comprises a valve base, a movable iron core and a deflation valve, and a first through hole allowing the movable iron core to penetrate through is formed in the valve base; the movable iron core comprises a guide rod part and a connecting part which are oppositely arranged, the guide rod part is sleeved with an electromagnetic iron ring, the movable iron core is movably arranged in the axis direction of the first through hole, the deflation valve comprises a contact part and a guide part which are oppositely arranged, and a compression spring is arranged between the connecting part and the valve base. The bypass mechanism is arranged in the turbine box, opening and closing of the deflation valve are controlled through cooperation of the electromagnet ring, the movable iron core and the compression spring, and along with change of the working condition of an engine, as the magnetic force of the electromagnet is in direct proportion to the current, the bypass mechanism is arranged in the turbine box. Therefore, the opening stroke and the waste gas bypass amount of the deflation valve are controlled by controlling the current of the traction electromagnet.

Description

technical field

[0001] The invention relates to the technical field of turbocharging, in particular to a controllable built-in electromagnetic wastegate turbocharger. Background technique

[0002] The turbocharger is a mechanical device that uses the exhaust gas energy discharged from the engine to further boost the pressure. It uses the exhaust gas energy of the engine to drive the turbine in the turbine box to rotate. The turbine drives the coaxial compressor impeller to work. The fresh air is filtered by the air. The cleaner enters the compressor, and the impeller of the compressor rotates to compress the fresh air to achieve the effect of supercharging. Therefore, the turbocharger can effectively recycle the exhaust gas energy, increase the air volume in the cylinder with the same displacement, optimize the combustion process, and improve the working efficiency of the internal combustion engine. Turbocharger is an essential part of modern engines to increase power, redu...
