Many people thought when complete, or did not use it for a long time in the morning, to idle the original geothermal car again after five minutes on the road, think it is good for the car, in fact not the case. According to a statistics show that DLF learned that engine parts wear parts for more than 90% of the proportion is within 3 minutes after cold start.

Hot car because the car after a long period of time of parking, engine oil flows back to the engine in the bottom of the oil sump. DLF said after so long ago in the car (e.g. overnight) to start the engine, the engine is in upper no oil lubrication. It takes about 30 seconds after launch because of the oil pump operation, the engine oil to the engine most in need of lubrication of piston connecting rod and crankshaft and other parts. But even after the engine immediately on the road, as long as you don't accelerator pedal motorcycle racing, keep running at low speed, the effect is the same operation and idle.

In addition, the engine before failed to reach operating temperature (about 90 to 110 degrees Celsius), the oil supply system cannot effectively because of the low temperature of gasoline complete gasification temperature of the liquid (believe everyone know to rise to the boiling point is vaporized). There is a "wet" are not gasification in gasoline and when the liquid is not easy to burn and start the engine. This relies on the role of the choke stopped some air into the cylinder to enhance the fuel/air mixing ratio and improve the engine speed makes the engine does not die. After reaching the normal operating temperature automatic choke will naturally due to mechanical action and return to normal state. Manual choke car be sure to remember to put the choke back, otherwise for oil/gas mixing ratio not only high waste gas, power, and incomplete combustion of gas will smoke.

About the gearbox change gear lubrication is the most easy to ignore people. Transmission gear oil and engine oil in the same place is: in cold vehicle gear oil flow to the gearbox lower half. Only when driving because of the operation will be at the bottom of the gear oil of gear, lubrication upper half. This is why most of the car in the cold car shift crude. The solution is not the original geothermal car can, right way should be running at low speed is slow.

DLF said, according to the above three original geothermal idle car is unnecessary, because the effect is limited, but also waste of petrol and time, and the engine idle speed idling, gasoline may also caused by incomplete combustion carbon deposit is more likely to damage the engine.

The right way to hot car should be 30 seconds after launch to hit the road in a minute. DLF remind but never high speed driving, at this time should be kept in a low speed engine speed is not more than 3000 ~ 3000 RPM. Generally keep 2000 turn, otherwise the engine and gearbox are intense wear, unable to recover. After being engine temperature rise to normal operating temperature, and restoring the driving method of the personal habits.

Car maintenance, the engine parts wear problem is outstanding, of which more than 80% of the reason is because the owner did not grasp the hot hot car or not caused by the car time has fast speed.
