The utility model provides an engine detonation pressure overrun limiting device, an engine and a vehicle. Relates to the field of engine operation control and comprises a controller, a first valve and a second valve, and the first valve and the second valve are respectively connected into the controller. The second valve end is butted with an engine intake pipe, and the other end is butted with an engine exhaust pipe; the controller is connected with a pressure measuring element and a temperature measuring element, the pressure measuring element obtains the pressure of the air inlet pipe and sends the pressure to the controller, the temperature measuring element obtains the environment temperature and sends the environment temperature to the controller, and the controller is used for controlling the opening degree of the first valve and/or the second valve. In order to solve the problem of unstable operation of an engine caused by inconvenient adjustment of the intake pressure of the engine at present, a byp
