冬季天气越来越冷了，特别是北方多地的气温也跌破了“冰点”，瞬间由“常温模式”转为“雨雪冰冻模式”。当然车主们纠结的问题也随之而来。雨雪严寒的冰冻天的早上，爱车是“点火就走”还是“原地热车三分钟”?到底正确的热车方法是怎样的?热车多长时间合适?  很多人知道要热车，但并不知道为什么要热车。大多数车主认为一大早或长时间不用车，发动车子以后，以怠速原地热车，等个三五分钟再上路对车最好。现在我们上海轿车托运公司为大家说到汽车冷车启动时候，很多车主常进入的误区，常犯的错误！告诉您如何正确的启动方法！

　　In winter, the weather is getting colder and colder, especially the temperature in the north of the North has also fallen out of the "freezing point". Of course, the problems that the owners are entangled are also coming. The cold rain and snow frozen morning, the car is "fire away" or "in situ hot three minutes"? What is the correct way to do? How long is right? Many people know but do not know why the hot, hot. Most of the owners that morning or long time no car, start the car after the in situ hot idle, wait 35 minutes on the car again for the best. Now we Shanghai car consignment company for everyone to say that car cold car start, many car owners often enter the misunderstanding, often make mistakes! Tell you how to start the right way!

　　1、打不着火连续启动

　　1. Continuous start without fire

　　第一次启动不着，间隔20秒左右后再进行第二次启动，启动后不要着急行驶增加预热时间。一般车辆水温达到40度起步最节约车子。

　　The first start is not, the interval of 20 seconds or so after the second start, after starting, do not hurry to increase the preheating time. General vehicle water temperature reaches 40 degrees to start the most saving car.

　　2、过分依赖启动液

　　2. Excessive reliance on the starting fluid

　　启动液具有易挥发、燃点低等特点，在低温下可缩短发动机启动时间。但车在户外放置时间过久，发动机各摩擦副之间都会出现无润滑油情况，此时若用冷启动液助启动的话，发动机严重会造成冷拉缸或烧瓦事故。在用冷启动液之前对油箱和油底壳进行一定的预热使发动机内各运动部件得到良好润滑，安装油箱加热器进行预热。

　　The start-up liquid has the characteristics of easy volatilization and low ignition point, which can shorten the starting time of the engine at low temperature. But the car is placed outdoors for a long time, the friction between the engine side there will be no oil, if the cold start with liquid can start, the engine will cause severe cold or burning accident cylinder. Before the cold start fluid is used, the fuel tank and the oil pan are preheated to make the moving parts of the engine well lubricated, and the heater of the oil tank is preheated.

　　3、启动后猛踩油门

　　3. Stepping on the throttle after starting

　　冷起动后猛踏油门，机油泵会高速运动，泵油量和泵油压力急剧增大，而与其相连的机油滤清器以及机油压力传感器一时难以承受这么高的油压，容易导致滤芯膨胀，甚至涨破。正确的操作是在发动机的温度升高到40摄氏度以后再适当加油准备起步。三大因素引发车辆冷车启动怠速抖动。

　　After a cold start with the throttle pedal, engine oil pump will be high speed, oil pump and oil pump pressure increases rapidly, which is connected with the oil filter and oil pressure sensor are difficult to bear such a high pressure, easily lead to filter expansion, even broken up. The correct operation is to start the engine properly after the engine's temperature rises to 40 degrees centigrade. The three major factors trigger the idle jitter of the vehicle cold car.
