AI Technical Summary
Technical Problem
Existing automobile engine intake systems are vulnerable to water ingress during flooding, leading to engine damage due to water entering the intake pipe and combustion chamber.
Method used
An engine intake pipe equipped with a blocking device featuring an elastically deformable expansion hood that switches between idle and working states, expanding to block the flow channel when water enters, using a gas-producing reactant to rapidly expand and prevent water ingress.
Benefits of technology
Effectively prevents water from entering the engine intake pipe, thereby protecting engine components from damage by rapidly blocking the flow channel and ensuring engine safety.

Abstract
The utility model relates to an engine air inlet pipe, an engine assembly and a vehicle, the engine air inlet pipe comprises a pipe body and a blocking device, and the pipe body defines a flowing channel for a medium to flow and is provided with an air inlet and an air outlet; the blocking device is installed on the pipe body and comprises a blocking assembly, the blocking assembly comprises an expansion cover capable of being elastically deformed, a second containing cavity is defined by the expansion cover, an expansion structure is arranged in the second containing cavity, the expansion structure has a working state and an idle state, and the working state of the expansion structure is different from the idle state of the expansion structure. When the expansion structure is in an idle state, the air inlet is communicated with the air outlet; when the expansion structure is in a working state, the expansion cover can expand under the action of the expansion structure so as to block the circulation channel. According to the engine air inlet pipe, the situation that an engine is damaged due to water inflow of the engine air inlet pipe can be effectively avoided.
