Common-Rail Direct Fuel Injection (CRD) is a high-pressure injection system for diesel engines with direct injection. The central part of the system is a shared (common) high-pressure delivery rail. The CRD system keeps the fuel at a constant high pressure and pumps it through variable and exactly adjustable injector nozzles along the common rail. The advantages of the common-rail system are high performance and reduced fuel consumption, minimal emissions and quieter operation.
The advanced electronic injection system, found on Caliber's 2.0L CRD Turbo Diesel and Nitro's 2.8L CRD Turbo Diesel engines, is highly adaptable. Its common-rail architecture and electronic controls make the system capable of new features, such as multi-pilot injection (to smooth combustion and quiet the engine), and high operating pressures that the hydro-mechanical system used in older engines cannot duplicate. These new features contribute to smoother, quieter operation and compliance with the more stringent exhaust emission standards.
