Winter heat loss of engine oil

Winter heat loss of engine oil in-place short hot car can be idling when driving
After cold start idle hot car, so, the original hot car was idling swift hot car, is still controversial. The view was expressed that, original hot car gearbox did not "move". Because, in the cold car, gear oil flow to the lower half of the gearbox. Only when driving, before the bottom of the running gear may be gear oil, lubricate upper part.
Technicians believe that, however, the original hot and idling the car slowly driving are among the hot car. The geothermal process should not be cancelled, there should be at least 30 seconds or so at a specific time, operation of the oil pump to transport oil to the most in need of lubrication of the engine piston, connecting rod and crankshaft and other components. Subsequently, the vehicle can be started. But, beginning within a short distance of the two hundred or three hundred meters, vehicle owners not to step on the gas. General operation is in accordance with what is said above, water temperature and speed standards and step on the throttle again.
Cold start should not be the heater
In addition, recently in particular, it is very cold in the morning, the owners crawl out from under the work, like to turn on the air conditioning blows warm air in the car. Need to be aware of is that cold starts hot car before the completion is not open after heating. From the energy point of view, winter launch vehicles overnight to open the heater, just blows out cold air, car has not hot air conditioning warm-not so fast, this will waste fuel.
Hot car is finished the water temperature and speed
Many owners in hot car after cold starts, but for how long no clear concept hot car. Some feel the need to 3-5 minutes, some believe that 30 seconds is enough. Shop technicians are not the answer. Asked the reason professional summary may also be because the specifications of the car is different, different experiences, different condition, hot cars vary in time. More mainstream ideas is that models currently on the market, as technology improved, hot cars than older models of vehicles be reduced correspondingly. Specific heat time can refer to two targets, one water, one is the engine speed.
Some owners hear vehicles as technology improves, hot car this step can be omitted. In order to work in a hurry often stopped overnight after the vehicle starts out. Almost all of the professionals when it comes to the driving habits, have argued that their loss of engine oil. According to reports, the engine after a night's rest, the lubricant on the friction surface residual stress disappeared, losing oil protection, low temperature viscosity of lubricants increased adhesion and liquidity. So, not hot car engine wear is considerable. Meanwhile, after a cold start the engine, then step on the gas grid, as temperatures are still low, fuel atomization is not sufficient, not burn completely easily formed Coke, oil.
In General, if in the process of idling hot car, you first need to speed back to normal idle speed of the engine. Some German cars high speed, until after its start at about 1000 rpm can run, other models have an idle state about 800 or so. This is one of the conditions you need to meet. Another condition is the instrument panel indicated a change in water temperature, you can advance the throttle travel. Some owners probably will wait until the water temperature rises to 70~80sheshidu to normal traffic, is also a good choice.
