Description

[0001] Field:

[0002] The invention belongs to a combustion system of an engine, in particular to a dual-fuel homogeneous compression ignition / quasi-homogeneous compression ignition composite combustion system. Background technique:

[0003] At present, the application of natural gas in the engine mainly has the following types: 1. The traditional ignition method is used for port injection or intake air mixing. The disadvantage of this method is that due to the limitation of knocking, the compression ratio of the engine is low, so the thermal efficiency is low. , high fuel consumption rate; on the other hand, due to the flame propagation process, the flame front generates a large amount of NOx emissions, which requires the use of noble metals such as platinum as a post-processing device for catalysts; at the same time, due to the high octane number of natural gas, high-energy spark plugs are required . The second is to adopt the diesel / natural gas dual fuel method, which is ...
