Problems solved by technology

At present, the turbochargers on the market all use the engine oil in the main oil passage of the engine lubrication system to lubricate the turbine shaft and bearings. Since the turbocharger is in a high temperature and harsh working environment, its lubrication effect will inevitably be affected.

Abstract

The invention discloses an engine turbocharger provided with an intelligent lubricating device and a system thereof. The engine turbocharger structurally comprises an engine sump, an oil pump and a turbocharger body, wherein the turbocharger body comprises an electromotor oil pump, a normally closed solenoid valve, a normally open solenoid valve, a supplementary oil way and a normally open oil way; and the system comprises a control unit, an oil pump motor unit, a normally closed solenoid valve unit, a normally open solenoid valve unit, an engine control unit, a comfort system control unit, avehicle door dead lock signal unit, a safety belt lock catch signal unit and a plurality of CAN network cables. Compared with the prior art, the engine turbocharger and the system thereof overcome thedefect that lubrication of an existing turbocharger is poor before the engine is started and after flameout of the engine without changing the original engine structure.

Description

Technical field [0001] The invention relates to an engine turbocharger with an intelligent lubrication device and a system thereof, and belongs to the technical field of engines. Background technique [0002] Turbocharged engines are superior to traditional flat suction engines in terms of power, economy and emissions; how to use a small displacement to obtain greater power and less emissions, the technical focus will be concentrated on the small exhaust The amount of turbocharged engine, so turbocharging technology is also the current development trend of fuel vehicles. However, the biggest problem in the application of turbochargers is insufficient lubrication, including lubrication lag during start-up and lubrication stop after flameout, so that the bearing cannot be adequately obtained during the initial start and a period of time after flameout. Lubrication leads to bearing wear and oil seal damage. The lubricating oil is sucked into the engine, causing the phenomenon of oi...
