The correct method of hot car, how long is the hot car time?

Today, we answer a question that many people ask. What is the best degree or state of hot car?

first, let's talk about what idle speed is. Idle speed is the lowest speed that can keep the engine running when the engine enters the normal working state. Now idling is not only to keep the engine running, but also to consider laws and regulations. As we all know, when the engine speed is very low, hydrocarbons will increase because the cylinder scavenging is not clean, which is illegal. After driving for an hour or two, the temperature was normal. Generally, the speed is about 7 to 9 rpm, so this state is basically idle. Many friends say that you nag about the hot weather every day.

hot penetration means entering idle speed.

the engine is a thermal engine.

when the heat reaches a certain level

at this time, the minimum speed is idle.

more popular.

according to the formula, it is not the second.

why does the diathermy car idle?

the idle speed is controlled by the water temperature sensor.

that is, the engine water temperature rises.

reach the overall thermal state of the car.

at this time, the water temperature sends a signal to the computer ECU.

send a command signal to the idle speed control system.

this is to keep the idle speed control in this state.

as long as the car is too hot.

the idle speed changes from fast idle speed to normal idle speed.

when people know that cars are cold.

in cold weather, take a taxi from 12 to 15.

different engine working conditions, different temperatures and different gasoline states.

there will be some differences in rotational speed.

the water temperature rises to a certain extent.

normal operating temperature of the engine

high idle speed. It's that simple.

many friends ask how long it will take to heat up.

thermal penetration has nothing to do with time.

but it's hot enough to be idle.

it is not directly related to time.

only related to ambient temperature and combustion conditions.

the combustion condition is normal combustion.

the engine is hot through quickly.

there is another case, if the engine has some carbon pollution.

when there is carbon deposit in the combustion chamber, it is equivalent to covering yourself with a thermal quilt.

this heat will not interfere with the water jacket.

this leads to a long warm-up time.

Some friends haven't been hot enough to sit around for ten minutes

This proves that the engine has serious carbon pollution.

carbon itself has the function of heat preservation.

even if you can't keep warm, you can't get through.

this causes the water temperature to rise for too long.

the carbon pollution level of any engine is different.

in this case, the warm-up time will be different.

as long as it is hot under the working conditions of the engine.

we all know that there is always an increase in engine oil with small displacement and T.

that is, after the mixture enters the lower cylinder, it absorbs oil.

causing too much oil.

after a few minutes, the piston will not heat up, but will descend.

a large amount of gas or mixed gas dilutes the oil.

Because the structural characteristics of the crank connecting rod of today's engine

have not changed.

because the automobile engine is a hot engine.

when the heat is less than the idle speed, it belongs to the warm state.

at this time, the fuel injection amount is also large, and the decrease amount of mixed gas is also large.

the oil will be diluted quickly.

I hope today's explanation will help you.
