Abstract
The application discloses a valveless pulse jet engine quick starting device and method, which comprises a valveless pulse jet engine, an igniter, a blowing system and an oil supply system; after alcohol is filled in the alcohol tank and the engine starts, the igniter starts to work first, alcohol is pressed into the combustion chamber by fuel, the blowing system blows high-pressure air into the combustion chamber from the air inlet, and the blowing system and the igniter are closed in turn after a period of time, so that the engine can be started reliably. The method of the application can improve the starting reliability of the engine and greatly shorten the starting time of the engine by using alcohol combustion assisting preheating and high-pressure air blowing excitation.
