Increasing air compression, that is the amount of gas included in the same volume, at the same time, its temperature is increased. Higher temperature is connected with lower density, which means that cylinders receive the amount of oxygen smaller than if the air temperature were lower. Therefore, a charging air radiator (intercooler) is used. Most frequently, this is an air exchanger of air-air type or (seldom) air-water.
Cars equipped with turbo compressors have the following properties:
A turbo charged engine is capable of generating the power 7 times higher than its atmospheric, not charged counterpart. Formula 1 engine, which was used a few years ago, may serve here as an example, which with capacity of 1.5l generated the power exceeding 1000 KM on the wheels. In standard conditions, it is possible to double the power of atmospheric engine, making the car react faster to driver`s commands, which results in safety. Turbo charging also prevents engine power drop along with increasing height above the sea.
Turbo compressors use and process energy generated by gases leaving the engine, transforming it into power. In consequence, charged engines are considerably more fuel efficient than their atmospheric counterparts.
Since a turbo compressor supplies considerably more air to the engine, there is more efficient and complete combustion in the cylinder chamber, and as a result “clearer”. Today`s turbo diesel engines generate approx. 50% less NOx and CO2 than traditional engines.
