Is there anything to pay attention to in the hot car with turbocharged engine?
Whether it is a naturally aspirated engine or a turbocharged engine, a hot car is needed when the cold machine is started. of course, the external ambient temperature has a great influence on the hot car time. We can't copy it mechanically, as long as we have a car that suits us.
A car is made up of many precision parts. The "turbine engine" engine has a more complex structure and a larger load than an ordinary natural intake engine. However, if the engine is stopped and turned off immediately, or if it starts running without preheating, the service life may be shortened.
If the temperature of the engine oil is low, the fluidity of the oil is poor, so when the engine is not started, the oil released from the oil sump will be slower and thicker. When the engine is hot, the oil released after the hot car has much better fluidity and less viscosity, which will make the oil cleaner and faster. If the temperature is about 20 degrees, the hot car can take 20 seconds, if the temperature is about 10 degrees, the hot car can be about 40 seconds, and if the temperature is about 0 degrees, the hot car can be hot for 1 minute. The first hot car is a hot engine, because the engine did not start for a long time, most of the oil inside the engine fell back to the engine oil sump, and the oil in the case of cooling, the fluidity is not very good, so it needs a hot car link.
When the engine is cold started, when the idle speed falls to 1000, or after the water temperature rises a little, the speed can be controlled at about 60, and the engine speed does not exceed 2500 rpm, and then the hot car is carried out. This is also a hot engine and gearbox, basically driving for about 3 minutes, basically the engine water temperature and oil temperature have reached the normal working temperature. At this time, you can throttle as much as you like, that is, the hot car is over.
Last but not least, the hot car steps of turbocharged engines are the same as those of naturally aspirated engines, but the specific hot car time depends on the external environment. When the ambient temperature is high, we can usually ignite and leave. Hot cars are carried out during driving to avoid rapid acceleration.
