Abstract

The invention relates to the technical field of internal combustion engines, and provides an ignition system. The piston is mounted in the machine body; the cylinder cover is installed at the opening position of the machine body, and the machine body, the piston and the cylinder cover define a main combustion chamber; the pre-combustion device comprises a shell, a main combustion chamber and a main combustion chamber, the pre-combustion chamber is formed in the shell; the jet hole is formed in the end, located in the main combustion chamber, of the shell and used for communicating the pre-combustion chamber with the main combustion chamber. The first fuel injector is arranged on the shell and used for injecting first fuel into the pre-combustion chamber; the first fuel injector is arranged on the shell and used for injecting first fuel into the pre-combustion chamber, the second fuel injector is arranged on the shell and used for injecting second fuel into the pre-combustion chamber, at least one part of the first fuel is subjected to compression ignition in the pre-combustion chamber and used for igniting the second fuel, and the engine comprises an ignition system and a control unit.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an ignition system and an engine. Background technique [0002] In order to effectively improve the stability and rapid combustion capability of the internal combustion engine based on the lean-burn technology. In the prior art, the main combustion chamber and the pre-combustion chamber connected to each other can be arranged in the internal combustion engine. combustion in the combustion chamber. [0003] In the process of practical application of the internal combustion engine with the above structure, the adjustment of the fuel-air equivalence ratio of the pre-combustion chamber as a whole is limited, which may easily cause the combustion stability of the engine to decrease or even misfire. Secondly, for some fuels with low combustion activity, the lean combustion of the lower main combustion chamber cannot be satisfied under low load conditions. [0004...
