Cylinder pressure data at different oil temperatures (20℃、30℃、40℃) and corresponding different spark angles (0oBTDC、6oBTDC、12oBTDC ) were sampled in experiments of BN491DQ engine. Emissions at start were measured. Ignition advance angle, combustion cycle variation, intake system difference affect cold start. The deeply research has got some important conclusions.

实验采集了BN491DQ发动机在不同机油温度（20℃、30℃、40℃）对应不同点火提前角（0oBTDC、6oBTDC、12oBTDC）的气缸压力数据，对冷起动的排放，点火提前角、燃烧循环变动、进气系统差异对冷起动的影响进行了深入研究。
