Perspective on Low-Temperature Combustion Applied to the Strategies of NOx Emission Reduction

Abstract

Compression ignition engine and PPCI-Partially Premixed Combustion Ignition, in which part of the fuel is sprayed on the fill line and the remainder is directly sprayed in the cylinder, bringing the advantages of both gasoline engine (fuel blends well with air) and diesel engine (compressed by compression). At the same time, it is possible to control the burning time of the mixture and the engine is stable and continuous thanks to the second fuel injection directly in the combustion chamber. This new method of forming mixtures and fire concepts in engines can solve both the problem of toxic combustion and emissions on internal combustion engines as well as energy security due to the use of various types. renewable fuel.
