Turbo is briefly overfeed. In other words, it is a system that works with the aim of obtaining more torque from the vehicle engine with its charging system. It is an air pump in general. The unit consists of a turbine wheel, a compressor wheel and a shaft connecting them. When the pressure laden exhaust gas comes to the stage of leaving the car's engine, it is directed to the turbine wheel of the turbo system. The shaft in the hub rotates with the turbine and allows the compressor wheel to be turned on the other side of the shaft. Thus, the compressor starts rotating at high speed. It absorbs high volumes of air and sends it to the cylinders of the engine. In order to increase the efficiency of the turbo system in vehicles, the intercooler unit, commonly known as a coolant, is added in between. The air temperature exiting the turbo unit reaches about 160 degrees. This hot air is cooled by passing it through the intercooler unit. Thus, the density of the air is increased. The air density increases, causing more air to enter the vehicle cylinders. The most sensitive and noticeable point of the vehicles with turbo engines is that the vehicle is kept idle for a while in starting and stopping the engine. The vehicle must remain at idle speed until the engine oil pressure reaches the desired level at first. The gas should not be depressed in the neutral position. This period should be extended on cold days.
