Description

technical field

[0001] The invention relates to the technical field of power machinery, and more specifically, the invention relates to an air intake management test system for an internal combustion engine. Background technique

[0002] With the increasing number of automobiles in our country, the emission of automobiles has attracted more and more attention from the country and the government. With the increasingly stringent emission regulations, automobile companies have taken a series of measures to improve the performance of the engine so that it can organize combustion as fully as possible, such as variable valve timing technology, multi-valve technology, variable swirl At the same time, a series of advanced post-processing methods are adopted to achieve the purpose of fully controlling emissions. In short, with the stringent national emission regulations and the improvement of market requirements, it is necessary to start from two aspects of the oil supply system and...
