三测量结果的比较和分析一、两种气缸盖温度的比较(已登在上半部)二、各种因素对缸盖温度的影响1.进气温度对缸盖温度的影响进气温度对缸盖温度的影响如图12所示。当进气温度升高时,缸盖温度也升高,功率下降。进气温度平均每升高10℃,高温区缸盖温度升高3～7.5℃,功率下降1.5～3%。这是由于进气温度升高后气缸充气量减少、燃烧变坏的缘故。
Comparison of three measurement results and analysis First, the two cylinder head temperature comparison (has been posted in the upper half) Second, the impact of various factors on the cylinder head temperature 1. Intake air temperature on the cylinder head temperature Intake temperature The effect of cylinder head temperature is shown in Figure 12. When the intake air temperature increases, the cylinder head temperature also increases, the power down. Each time the temperature of the intake air is increased by 10 ℃, the cylinder head temperature in the high temperature zone is increased by 3 ~ 7.5 ℃ and the power is decreased by 1.5 ~ 3%. This is due to a decrease in the air charge of the cylinder after the intake air temperature has risen and the deterioration of the combustion.
