摘要
排气余热回收系统(EHRS)是一种汽车废热能量回收装置。在新欧洲驾驶周期(NEDC)不同温度冷起动工况下,对有无EHRS作用下的发动机冷却液温度,整车燃油消耗量,HC、CO和NOx排放进行对比分析,探讨EHRS装置对整车油耗及排放的影响。在-20℃复杂工况下进行空调采暖试验,探讨EHRS对乘座舱空调采暖舒适性的影响。试验结果表明:使用EHRS装置后,在NEDC(25℃)工况下,HC、CO和NOx排放分别减少约13.9%,3.9%和0.1%;在NEDC(-7℃)工况下,HC、CO和NOx排放分别减少约25.99%,13.91%和18.18%;在-20℃的复杂工况空调采暖试验中,乘座舱可以提前13min左右到达26℃,且平均温度升高了10℃左右。
Exhaust heat recovery system(EHRS) is a device for vehicle exhaust heat recovery. The coolant temperature, fuel consumption rate, HC, CO and NO x emissions were compared and analyzed on the engine with and without EHRS under different cold start conditions with different temperatures in new European driving cycle(NEDC), aiming to explore the influences of EHRS on fuel consumption and emissions of whole vehicle. In addition, the air conditioning heating experiment of passenger compartment was conducted under complicated condition(-20 ℃) to study the effects of EHRS on the comfort of air conditioning heating. Experimental results indicate that HC, CO and NO x emissions decrease by about 13.9%, 3.9% and 0.1% respectively under NEDC(25 ℃) while decrease by 25.99%, 13.91% and 18.18% approximately under NEDC(-7 ℃).And the temperature of passenger compartment reaches 26 ℃ about 13 minutes earlier and its average temperature increases about 10 ℃ by using EHRS in the air conditioning heating experiment with complicated condition(-20 ℃).
