Abstract

The invention provides an automobile and a method and device for protecting an engine used for the automobile. The method for protecting the engine comprises that data information, of the amount of water in an air inlet pipe, acquired by a water amount sensor is received; whether water enters the air inlet pipe is judged in dependence on the water amount data information; if water enters the air inlet pipe, the engine is controlled to stop working in dependence on a preset control strategy. By employing the method for protecting the engine, whether water enters the air inlet pipe of the engine can be judged quickly and accurately, when water enters the air inlet pipe of the engine, measures are taken quickly, and therefore the case that water is sucked into the cylinder body of the engine, and the engine body is damaged can be effectively prevented, and loss can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile and an engine protection method and device used therefor. Background technique [0002] With the popularity of automobiles, automobiles have entered thousands of households and become an indispensable means of transportation for people to travel. In the rainstorm season, due to urban waterlogging, some road sections are seriously flooded. Unknown drivers may cause water to enter the engine when passing by, which will cause engine damage and unnecessary losses. [0003] Currently, it is possible to passively stop the engine by adding a control device to the intake pipe to block water and gas from entering the intake pipe. However, the process takes a long time when this method is adopted, and it cannot effectively prevent water from being sucked into the engine block to cause damage to the engine body, so the engine is not effectively protected.
