In the car era of the carburetor, the hot car is very necessary. The domestic automobile engines 20 years ago were all used carburetor technology, and the carburetor required a suitable temperature for better atomization of the fuel. Before the operating temperature is reached, people are using hot wheels in order to obtain the best atomization effect. Why hot car? 1. After the car has been parked for a long time, the engine oil flows back to the oil sump in the lower part of the engine. Therefore, the engine is started after a long period of use (for example, overnight). At this time, the upper half of the engine is in a condition where there is no oil and lubrication is lacking. About 30 seconds after launch, the oil will be pumped to the pistons, connecting rods and crankshafts where the engine needs lubrication most. However, even if it is started immediately after the engine is started, as long as it does not slam the accelerator and keep running at a low speed, the effect is the same as that of idling. 2. Before the engine reaches the operating temperature, the fuel supply system of the engine is unable to fully gasify the gasoline because the temperature is still low. Does the car still use a hot car? From the oil's point of view: the oil with a viscosity value around 10 has a true lubrication effect. The viscosity of the oil in the cold state is around 40. With the increase of the oil temperature, the viscosity value becomes smaller and smaller, and the viscosity reaches 10 The longer the previous process wears away, the greater it will be. Therefore, the effective method of minimizing wear is to increase the cold start idle speed. This is the reason for the high idle speed of our car. It is the vehicle's computer settings. A hot car in situ is slower than a slow hot car, which increases the time for the oil to run in a high-viscosity state, but does not benefit the engine. From the perspective of gasoline: Modern automobiles have adopted electronically controlled gasoline injection systems, and carburetors have long since been eliminated (in 2001, the state banned the sale of carburetor vehicles). The working principle of the EFI system is completely different from that of the carburetor. Through computer control, the amount of fuel injected can be precisely controlled, and good atomization effects can also be ensured. The rotation speed can be stabilized within a very short time after start-up, and the external temperature influences it. Very limited, so no warm-up is needed. The hot car is not needed. The best way is to keep the engine running at a low speed after the fire. The temperature rise of the components can help the engine to warm up more quickly. Personally think that the method of replacing the local hot car at low speed is more effective.
