Turbo engine works by supplying additional air into the engine to produce more complete combustion, thereby increasing the engine power produced. Turbo engine in the early days, only work to pump extra air into the engine using exhaust fans . The fan rotation will rotate the turbo pump with the help of connected shaft, thereby ensuring the total air exit are same with amount of air enter into the engine.
However, if the entry of air into the engine is over the limit, it can damage the engine. Therefore, an additional air release device known as "Westgate" must be installed to prevent this from happen. This "Westgate" will act to ensure that the number of air pumped into the engine does not exceed the prescribed limit.
Compressed air by the turbo engine will raise the temperature of the air in the engine. The engine will becomes hot. To prevent the engine from overheat, air is pumped-in using cooling device known as intercooler. Usually intercooler will be installed at the front of the vehicles.
If the turbocharged engine is turned off by sudden, the pump is not pumping more oil to the turbo lubricating system . This situation will increase the friction in the turbo engine, which will enhance the rate of turbo thirst system and damage the component in the turbo system.
Therefore, to avoid this situation, turbocharged engines must be stabilized by letting it running for 20 to 30 seconds before the engine is switch-off . For those who do not want or do not have time to wait before turning off the engine, a tool known as the "turbo timer" can be installed. It can be set to turn the engine off after the preset time passed.
In addition, turbocharged engines should also be warm-up before starting the journey to ensure that lubricating oil has been spread all over the engine. For turbocharged engines, users are recommended to use lubricants that hold high temperatures, especially synthetic oil.
