Description

Technical field [0001] The present invention relates to the field of diesel engine technology, in particular to a big data-based combustion chamber processing parameters affect emission detection methods and systems. Background [0002] The piston combustion chamber is an important part of the diesel engine. Piston combustion chambers have a direct impact on the power, economy and emissions of diesel engines. At present, due to the entry of emissions into the National VI stage, the NOx emission limit has been greatly reduced, and the sensitivity to emission fluctuations has increased, and it is necessary to control the processing quality and improve the consistency of emissions to enhance product competitiveness.
