The invention relates to a turbo-supercharger for an automotive engine, which is used for solving the problems of the complicated structure and larger occupied space of a two-stage supercharger in the prior art. The turbo-supercharger comprises a first-stage pressurizing mechanism, a gear transmission mechanism, a clutch device and a two-stage pressurizing mechanism, wherein the gear transmission mechanism consists of a driving gear and a driven gear; the first-stage pressurizing mechanism is assembled with the driving gear; the driven gear is assembled with the two-stage pressurizing mechanism; and the clutch device is arranged between the gear transmission mechanism and the two-stage pressurizing mechanism. The turbo-supercharger has the characteristics of simple structure and compact arrangement, and can satisfy the requirement of the engine on air intake quantity under different working conditions, so that the comprehensive performance of the engine is improved.
Description
technical field [0001] The invention relates to an engine turbocharger, in particular to a two-stage turbocharger for a vehicle-mounted engine, and belongs to the technical field of internal combustion engines. Background technique [0002] As we all know, the engine is the source of automobile power. It burns the mixture of fuel and air in the cylinder, pushes the piston to reciprocate and then drives the crankshaft to rotate, thereby converting the heat energy released by fuel combustion into mechanical energy. Since the conversion of engine power and fuel heat energy is directly proportional to the quantity of air (or mixture) in the input cylinder, and under the condition of constant cylinder volume and engine speed, the quantity of air (or mixture) supplied into the cylinder is proportional to Air density is proportional, so engine power can be increased by precompressing the air before it enters the cylinders. [0003] The exhaust gas turbocharger is a set of devices ...
