How does a modern Common Rail fuel injection system with ultra-high pressure (up to 2,500 bar) and multiple injection events per cycle improve engine efficiency and emissions?

1. Extremely fine fuel atomization ensures rapid, complete combustion; pilot injections soften pressure rise to reduce noise and mechanical stress, while precise main and post injections minimize particulate formation and support aftertreatment regeneration
2. It pumps fuel directly into the radiator to cool the engine
3. It eliminates the need for an air filter
4. It operates mechanically with a single fixed injection per revolution
