Abstract

The invention provides a lean-burn internal combustion engine system and a vehicle with the lean-burn internal combustion engine system. The lean-burn internal combustion engine system comprises an internal combustion engine controller; the switched reluctance motor is electrically connected with the internal combustion engine controller; the gas compressor is connected with the switched reluctance motor; the turbine is connected with the switched reluctance motor, and the switched reluctance motor is located between the gas compressor and the turbine. The hydrogen-injection lean-burn engine is communicated with the gas compressor through the throttle valve, the turbine is communicated with an intake manifold of the hydrogen-injection lean-burn engine, and the hydrogen-injection lean-burn engine is electrically connected with the internal combustion engine controller. The internal combustion engine controller controls the switched reluctance motor to serve as a motor or a generator under different working conditions, when the switched reluctance motor serves as the motor, the electric auxiliary supercharging function is achieved, when the switched reluctance motor serves as the generator, the turbine power generation function is achieved, and the utilization rate of high-grade energy in tail gas is increased; the problem that a traditional exhaust gas turbocharger is low in energy utilization rate is solved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a lean-burn internal combustion engine system and a vehicle having the same. Background technique [0002] Against the background of increasing greenhouse effect and increasingly tight oil resources, the call for reducing global carbon dioxide emissions is getting louder and louder. Reducing carbon dioxide emissions from automobiles has become a technological proposition that automobile manufacturers must consider. The low carbonization of automobile engines has become an important technology research and development trend. At present, the most mature and popular vehicle engine is the gasoline engine. The common types of gasoline engines are port injection gasoline engines and in-cylinder direct injection gasoline engines. The fuel economy of these two gasoline engines is restricted by some factors, and there is room for further exploration. [0003] The traditio...
