Abstract

The invention provides a piston ram self-ignition pulse-jet engine. A stepped free piston is mounted in an engine bod, and a pre-combustion chamber and a main combustion chamber are formed. The front end of the main combustion chamber is provided with a spout provided with a pressure control switch; a fuel pipe on one side and a low-pressure gas pipe are both communicated with the pre-combustion chamber and the main combustion chamber through air inlets; the inner front end of a cylinder block is provided with a vent way. The cylinder block is divided into the two combustion chambers, ignition is achieved by gas pressure, mechanical means or a spark plug, the pre-combustion chamber is controlled to combust first by one or any of the means such as photoelectricity and electromagnetic wave, the main combustion chamber is blast through the free piston, high-temperature high-pressure gas is formed and thrusts the spout open, thrust is generated, and no power turbine is required. The piston ram self-ignition pulse-jet engine can be switched to a rocket operation mode and is a dual-mode efficient engine ideal for aerospace, aviation, rockets and the like. Multiple fuels are available to the piston ram self-ignition pulse-jet engine, the structure is simplified, and the piston ram self-ignition pulse-jet engine can be combined with the existing engine to form novel engines.

Description

technical field [0001] The invention relates to an engine, in particular to a piston ram self-ignition pulse jet engine. Background technique [0002] All kinds of engines in use now have the function of converting oil and gas into power. At the same time, there are also disadvantages such as low fuel efficiency, low power density and serious air pollution. High efficiency, high torque, low fuel consumption, and low emission are the development trend of future engines and people's dreams for many years; in the current situation where energy sources are gradually depleted, the requirements for high efficiency and low consumption of engines are more urgent, especially for aviation, Aerospace and rockets have more urgent requirements for high-thrust-to-weight ratio and high-efficiency engines in civil and military fields. Contents of the invention [0003] The purpose of the present invention is to meet the urgent needs of the current aerospace, and provide a piston ram sel...
