Specifiion

Description

A significant difference between a turbocharged diesel engine and a traditional naturally aspirated gasoline engine is the air entering a diesel engine is compressed before the fuel is injected. This is where the turbocharger is critical to the power output and efficiency of the diesel engine.

It is the job of the turbocharger to compress more air flowing into the engine’s cylinder. When air is compressed the oxygen molecules are packed closer together. This increase in air means that more fuel can be added for the same size naturally aspirated engine. This then generates increased mechanical power and overall efficiency improvement of the combustion process. Therefore, the engine size can be reduced for a turbocharged engine leading to better packaging, weight saving benefits and overall improved fuel economy.

Characteristic

1.Reducing bearing frictional losses, e.g., using a foil bearing rather than a conventional oil bearing
2.Using variable-nozzle or twin-scroll turbochargers
3.Decreasing the volume of the upper-deck piping
4.Using multiple turbochargers sequentially or in parallel
5.Using an antilag system
