Engines that have a positive pressure forced into the cylinder, by an exhaust driven centrifugal compressor (turbo), are called:
What the reasons an engine may be turbocharged?
- It offsets the effects of decreased performance when operating at higher altitudes
- It increases the engines power output without adding much more weight
- It increases the power output without increasing engine size
It compensates for varying load demands during operation
- It decreases emissions due to an increased combustion efficiency and fuel economy
When an engine is turbocharged, the intake air temperature increases. What effect does this have on power output?
It decreases engine power output as the oxygen molecules are farther apart, therefore decreasing volumetric efficiency.
