基于增压发动机的PCV阀匹配研究

Investigation of PCV Valve Matching Based on TGDI Engine

为满足日益严苛的汽车排放法规要求,提高动力性和经济性,防止因PCV阀匹配失效导致的密封泄漏、排放不符合法规要求、机油消耗量大、机油老化和稀释、冬季管路结冰等问题,需进行PCV阀匹配研究工作。

To reach the requirements of increasingly stringent vehicle emission regulations, improve the power performance and fuel economy, prevent seal leakage, emissions not meeting the requirements of laws and regulations, oil consumption, oil aging and dilution, winter pipeline frozen caused by the PCV valve matching failure, PCV valve matching research work need to be done in this paper.
