There is only a turbocharged car, don't you need a hot car? In addition, we should also pay attention to the engine idling as much as possible, and the speed should not exceed 2000 rpm. After driving for 3 or 5 minutes, the engine can be started at will. Your own driving habits. Don't idle the turbocharged engine for a long time, and don't exceed 20 minutes.
The so-called in-situ heating is actually unnecessary, because in-situ heating will have many disadvantages. The automatic transmission also needs heating. If you idle in place, the transmission will not work and the heating effect will not be achieved. Idle running will produce a lot of waste gas, which is toxic and harmful. First of all, it pollutes the environment.
If your car is driven by external circulation and gas is supplied in the car, it will easily affect your health after a long time. As we all know, if the valve is not lubricated with lubricating oil for a short time, it will have little impact on the engine and only make noise, but the turbocharger is different. The two propellers are connected by a shaft, so there is no time for lubrication.
It will accelerate wear, increase axial clearance, lead to poor sealing and reduce the pressure of turbocharger on cylinder. Will lead to a decrease in horsepower. Because the wear of engine cylinder wall mainly occurs in the cold start stage of the vehicle. At the same time, if the vehicle is parked for too long, the engine temperature will not rise immediately after cold start.
Because the oil flows back to the bottom of the oil pan, especially in low temperature season, the engine liquidity is poor. If the oil and engine are not lubricated immediately, "dry grinding" will occur. At this stage, the cylinder wall of the engine has been basically worn. If the cylinder wall is excessively worn, the vehicle will have a serious oil burning problem and the power will be seriously reduced.
It may even be scrapped prematurely. Because the engine overhaul not only costs a lot of money, but also will be scrapped in a few years at most after tightening the cylinder and replacing the cylinder liner. The quality of all cylinder liners is not the level of the original car, so they are very wear-resistant. It can be seen that the basic components of turbocharged engines and naturally aspirated engines have not changed, and engines with the same displacement.
For example, 1.5L and 1.5T, with the letter L Atmospheric and the letter T Turbocharged. The output power of an engine with the same displacement should be increased by about 40%. Normal operation should wait until the tachometer reaches about 800 revolutions, because the turbine will not interfere at low speed, and the turbocharged engine is equivalent to a naturally aspirated engine and needs to be warmed up.
The specific preheating time can be seen at the bottom. It depends on the environment. When the ambient temperature is high, we usually turn on the ignition device to start, so that we can warm up the car while driving and avoid sudden acceleration. After the engine warms up for 20 seconds, shift gears and slow down. The gearbox also needs to be lubricated with oil.
Driving at a low speed for about 5 minutes, the gearbox will be full of parts that need lubrication, and the vehicle can run normally. Especially in cold weather, cars must be warmed up. Don't suddenly step on the accelerator after driving, drive at a low speed for a while, and then start driving normally. Developing good driving habits can prolong the service life of vehicles.
It should be noted that the turbine temperature is very high after long-term driving, and it is best to idle after stopping. Of course, the current car will automatically blow air to cool the turbine after the flameout. In addition, the current turbine technology is very good, in fact, the role will not be great. If the oil pressure is enough, the turbocharger will not break down so easily.
Hot cars in life don't need to idle for ten or twenty minutes. Depending on the local temperature, the seat belt will be idle for a few seconds or minutes. In winter, you need the original factory floor heating for 5 minutes, so you don't have to step on the accelerator and wait for the speed. After the warm-up instructions are finished, turn off the engine and start it again.
Press the accelerator pedal hard and drive slowly for 15 to 10-20 minutes, then you can drive normally. You don't have to keep warm outside in summer! Compared with the previous engines, the current engines are more and more scientific with the continuous development of science and technology. That is to say, cars can go straight on the road after a fire. But for many drivers, no matter what is written in the car manual, they are still used to hot cars.
