A Method for Preventing Engine from Spontaneous Combustion

Abstract

The present invention proposes a method for preventing engine spontaneous combustion, the method comprising the following steps: detecting whether the engine is in a running state; judging whether the state parameters of the vehicle meet predetermined conditions; and if the state parameters of the vehicle meet the predetermined conditions , then intermittent oil control is performed on the engine. According to the implementation example of the present invention, the high-temperature self-ignition problem of the engine caused by misoperation is adjusted through intermittent oil control of the engine, thereby improving the safety of the engine and the vehicle.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to a method for preventing engine spontaneous combustion. Background technique [0002] There are many reasons for a car to spontaneously ignite. As the power source of the car, the engine is not only the core area of ​​the vehicle, but also a high-incidence area for spontaneous combustion accidents. When the driver is driving, the driver's own state is abnormal, such as sudden illness or drunkenness. , At this time, stepping on the accelerator on the spot will cause the engine to overheat, and the three-way catalytic converter will burn out, resulting in car crashes and deaths. Conventional fuel vehicles that are installed with mechanical throttle valves in the market are not equipped with safety measures for the above-mentioned situation, which has caused great potential safety hazards to the life and property of the driver. Since the control of the mechanical throttle ...

Problems solved by technology

[0002] There are many reasons for a car to spontaneously ignite. The engine as the power source of the car is not only the core area of ​​the vehicle, but also a high-incidence area for spontaneous combustion accidents. When the driver is driving, the driver's own state, such as sudden illness or drunkenness, often appears abnormal. At this time, stepping on the accelerator on the spot will cause the engine to overheat, and the three-way catalytic converter will burn out, resulting in car crashes and fatalities.

At present, conventional fuel vehicles equipped with mechanical throttle valves in circulation on the market have no safety measures against the above situation, which has caused great safety hazards to the life and property of the driver.

Since the control of the mechanical throttle is completely determined by the driver's intention, it may cause the driver to enter an unsafe operating state by misoperating the accelerator pedal if the driver is affected by force majeure factors.
