In winter preheat car considerations Winter cold, before driving preheat car is a lot of owners must have homework every day. Why, then, must be preheat car? If you start directly on the road, why there is a series of questions? Now let's have a look at the reasons for it! First, after a long period of time in the car parked, engine oil flows back into the lower part of the machine within the engine oil pan, the engine is in the upper half there is no oil, lack of lubrication conditions. Second, before the engine below the operating temperature (approximately between 90-110 degrees Celsius), the fuel system due to temperature is still low, are unable to effectively completely vaporized gasoline. Third, the transmission gear lubrication, it is generally best to understand most easily overlooked. Fourth, in the winter don't preheat car is damage car engine and waste oil. Preheat cars this thing would have been for car owners are not difficult, but because there are a variety of errors, the majority of owners are difficult to do properly preheat car. The following errors several preheat car, do you have? Error one, don't need preheat car in winter Error two, winter preheat car as long as possible Error three, "Step on the gas" can improve the speed of hot cars Error four launch x431 pro, with in-situ methods idling preheat car Winter car idling shake very common, usually caused by changes in the engine cylinder gas forces are likely to result in failure of the engine idle jitter. Now let's have a look at the system from the following causes idle jitter! (1) Four reasons leading to the intake system idle jitter: intake manifold or a variety of valve leakage; throttle and excessive intake fouling; idle air actuator failure; intake air inaccurate. (2) Fuel system jitter leads to idle four reasons: injector fault; fuel pressure failure; injection quantity inaccurate creader viii. (3) Leads to the ignition system idle shake four reasons: the ignition module and ignition coil; spark plugs and power lines; ignition advance angle misalignment; other reasons. (4) From the mechanical structure analysis idle jitter causes: valve, engine block, piston rod mechanism. Other reasons: Engine cold start wear accounts for about half of the entire amount of wear normal idling warm car can reduce this wear, thus extending engine life. But preheat car isn't the time as long as possible is the better, time as longer as possible the engine can achieve stable and normal idle speed can be driving it. Preheat car idling for too long, in addition to increased fuel consumption and coke, but to improve the device's operating temperature catalytic did not help. Also note that the car must be low-grade fever after slow driving, speed not look pulled too high, according to the situation and condition of the engine speed slowly changing speed. Best to wait until the water temperature reaches the water table in the second division (60 C) when driving at normal speed. In addition, not only the engine needs to be done in a timely manner of "warm-up " , gearbox, hydraulic power assist system, even the tires have to do "warm up ." Some diagnostic tools can help you maintenance your car very well, such as: Launch X431 Diagun 3 and Autel maxidas DS708. It can help you save time and money.
