怠速时间不要太长车子启动后在原地停留超过1分钟,不但损害发动机,也增加了二氧化碳排放。实验证明,发动机空转3分钟的油耗足够让汽车多行驶1公里。建议:不用原地热车,只要不马上加速,慢行几分钟让引擎热起来,再均匀加速就可以了。在等红灯或者等人时,超过1分钟或是堵车怠速4分钟以上,请马上关掉引擎。加速不要猛踩油门猛力加油要比缓慢加油多耗油12毫升左右,还会造成噪音污染、轮胎磨损和追尾风险。不要低挡行车较低的档位意味着较高的发动 Idle time not too long After the car started to stay in place more than 1 minute, not only damage the engine, but also increased carbon dioxide emissions. Experiments show that the engine idling 3 minutes of fuel consumption enough to allow cars to drive more than 1 km. Recommendation: do not use the original hot car, as long as not to speed up, slowly for a few minutes to let the engine heat up, then uniform acceleration on it. Wait for red light or others, more than 1 minute or traffic jam idle for 4 minutes or more, please immediately turn off the engine. Accelerate do not violently step on the accelerator fierce refueling than slow refueling more fuel consumption of about 12 ml, but also cause noise pollution, tire wear and rear-end risk. Do not lower the block lower gear means higher launch
