Embodiment Construction

[0011] exist figure 1 , 2 In the shown embodiment, the combustion chamber of the engine is formed by the cylinder head (1), the piston (2) and the cylinder liner (3). The fuel injector (4) is obliquely installed in the cylinder head (1), and the ignition chamber (6) with the spark plug (5) is also installed in the cylinder head (1), and the ignition chamber (6) is fastened in the cylinder head (1) by interference fit. The upper and lower parts of the cylinder head (1) protrude from the lower plane of the cylinder head (1). The ignition chamber (6) is provided with a fuel inlet (7), and several nozzles (8) for combustible mixture combustion flames are provided in different directions on the lower wall. A fuel beam (10) of the fuel injector (4) is directly injected into the inner cavity of the ignition chamber (6) through the fuel inlet (7), so that a thicker combustible gas is formed around the electrode of the spark plug (5), which is very conducive to ignition. mixed gas. ...

Abstract

The burning system of spark plug ignition room is used in igniting engine capable of burning several kinds of fuel. The burning system has one ignition room with one spark plug mounted, one fuel jet to jet the fuel beam directly into the ignition room to form thick inflammable mixed gas around the electrode of the spark plug for easy ignition and thin inflammable mixed gas outside the ignition room, so as to make the burning system ignited reliably and burnt completely. The engine has raised efficiency, improved exhaust performance, and lowered fuel consumption. Under high load, the fast flame jetting avoids detonation and decreases noise.

Description

technical field [0001] The invention relates to a spark plug ignition chamber combustion system, which belongs to the field of ignition engines that can burn various fuels. Background technique [0002] At present, at the instant of the spark plug flashover discharge of the ignition type engine, the flame of the combustible mixture ignited by the flashover starts to spread outward in a spherical shape near the electrode gap and spreads to the entire combustion chamber. Whether burning gasoline or liquefied petroleum gas and other fuels, ignition engines have low concentrations of combustible mixtures under low operating conditions and are difficult to ignite. In order to ignite the combustible mixture smoothly, the usual method is to increase the ignition energy of the spark plug, which not only consumes too much electric energy, but also causes premature wear of the spark plug electrodes. Contents of the invention [0003] In order to solve the problem that the ignition ...
