Sky cold car fears winter cold start misunderstanding inventory

Misunderstanding 1, can not start a continuous fire

Winter car battery power consumption is larger, the battery will generally discharge after parking in the evening, winter car static discharge for a long time, when the start will not start when the fire will continue to damage the battery.

When the first time does not start the fire, make a second start after an interval of about 20 seconds, do not hurry to increase the warm-up time after starting. General vehicle water temperature reaches 40 degrees to start the most economical car. It is advisable for card members to turn off the power-consuming device and then turn off the engine car before parking, and start the engine warm-up before turning on the air-conditioning radio and the like to prolong battery life.

Misunderstanding 2, excessive dependence on the starter

The starter fluid has the characteristics of easy volatilization and low ignition point. It can shorten the engine start-up time and prolong the service life of the battery under cold and low temperatures. However, when the vehicle is left outdoors for too long, there will be no lubricating oil between the friction pairs of the engine. The surface is in a state of dry friction. At this time, if a cold starter is used to start the engine, the engine suddenly generates a large impact and the amount of wear must be large. If the spray starter fluid is a little more serious, it will cause a cold cylinder or a burning tile. ACCIDENT.

Tank heater

The correct method is to use a certain warm-up of the oil tank and the oil sump before the cold start fluid is used so that all moving parts in the engine are well lubricated. Install the tank heater to warm it up. You can use the blowtorch to heat but it is not recommended that the open flame be present. Big security risks.

Misunderstanding 3, after starting a slam step on the throttle

Many truck drivers will slam on the throttle after the vehicle starts in winter. This actually has serious damage to the vehicle:

1, this will not only fuel consumption, but will exacerbate the wear of the engine, after the vehicle parks for a period of time, there will be no lubricant between the engine friction pairs, even if the engine has been started, but because the engine oil from the oil pan into each Lubrication points require a period of time. Due to the low temperature in winter, the viscosity of the lubricating oil is large and takes a relatively long time. If the engine has just started the cold start and slams on the accelerator, the moving parts in the engine will not be well lubricated, and the friction surfaces will be in a state of dry friction, and the amount of wear will naturally be great. In the long run, this will inevitably shorten the service life of the engine. Pull cylinders or tiles, and damage engine components.

Burning tile

2. Due to the large viscosity of the oil in the winter, the throttle is struck after starting, the oil pump will move at a high speed, the pump oil quantity and the pump oil pressure will increase sharply, and the connected oil filter and oil pressure sensor will not be able to withstand such a high one at a time. Oil pressure can easily cause the filter element to expand and even burst. Although some automobile oil pumps have pressure limiting valves installed on them, they can play a protective role to a certain extent, but due to the large viscosity of the oil in the engine during the winter, the engine components will still be damaged.

In short, slamming the throttle after a cold start has nothing to do with the performance of the engine. The correct operation is to start the engine properly after the temperature of the engine has risen to 40 degrees Celsius.

Myth 4, direct start after start

Starting from the start to do so on the vehicle damage is very great, because just started the various parts of the engine oil is not yet in place, the engine temperature is low, will produce mechanical dry grinding, resulting in early wear of cylinder liners, journals, gears and other components.

After starting up, it should be heated up for a while and wait for the water temperature to rise and reach normal speed before starting off. After starting the car, it should travel steadily for several kilometers until the vehicle reaches a good warm-up state and then speeds up.

However, the warm-up time does not need to be too long. The general judgment criteria are as follows: The pointer of the water temperature gauge has just started to move, or the engine tachometer has started to fall back to the idling state and can be driven. It takes about one minute or so. In addition, the first 2 km after the start of the first low speed, and then normal speed, so as not to turn off.

No matter which kind of engine is difficult to avoid difficulties in the cold winter, the more you should avoid reckless operation damage to the engine, develop good habits for your car is responsible as a qualified truck driver. The necessary conditions.
