Diesel common rail direct injection (CRDI) and its benefits

Common rail is a fuel injection system found in modern diesel engines. Common rail systems provide a level of flexibility which can be exploited for class leading emission control, power and fuel consumption. This enables Original Equipment Manufacturers (OEMs) to design for optimum performance and exceptional end-user value across a range of machines and applications.
