Abstract

The invention relates to an ignition device of a heavy oil piston engine. A sparking plug (3), a gas spraying pipe (4), a pressure difference valve (5), a pressure reducing valve (6), a gas storing device (7) and a pressure difference valve control pipe (8) are included; the pressure difference valve (5) is composed of a valve element (9), a spring (10) and a valve body (11); and the valve element(9) is further provided with a vent hole (12). By means of the ignition device, the ignition energy of the heavy oil piston engine can be substantially improved, the technical difficulty is small, cost is low, and altering on the engine is small.

Description

technical field [0001] The invention belongs to the field of aviation piston engines, and relates to an ignition device, in particular to an ignition device for a heavy oil piston engine. Background technique [0002] Piston engines generally use gasoline as fuel, but gasoline fuel is volatile and prone to safety hazards, so it is not suitable for long-term storage. Heavy oil can solve the problem of volatilization, but it is not easy to ignite. [0003] In response to such problems, the commonly used method in the world is to improve the spark plug, increase the ignition voltage to make the ignition energy higher, or turn to study compression ignition to increase the gas pressure. But from the current point of view, these ignition technologies still have disadvantages such as difficulty, high cost, and large engine changes, which are not conducive to popularization. [0004] Therefore, need a kind of novel ignition device that technical difficulty is little, cost is low, e...
