The Influence of Vehicle's Intake Temperature on Power Performance
With the development of the economy and the increase in household income,the number of pri-vate cars has gradually increased.During the rush hour of commuting,urban congestion has become in-creasingly apparent,and cars cannot travel smoothly.During the period of traffic,there are more and more idle and low-speed conditions.At this time,increasing the throttle often leads to insufficient power re-sponse and slow starting.One of the reasons is the high intake temperature,which leads to a decrease in in-take density and an increase in knock tendency,Delaying the ignition advance angle leads to a decrease in combustion efficiency,ultimately resulting in low combustion efficiency and reduced performance.How to reduce the intake temperature has become increasingly important for various engine manufacturers.By u-sing theoretical analysis and thermal load experiments,the structure of the entire vehicle's intake system was planned.From various aspects such as arrangement of air intake,and selection of materials,the intake temperature has been effectively reduced.
