CRD engines are diesel turbocharged engines with a direct fuel injection system, installed on Chrysler, Dodge, and Jeep cars. They have been available since 2000. These power units are produced by VM Motori, Fiat Powertrain, Volkswagen AG, and Daimler AG. They are characterised by high performance and excellent torque values.
Features of CRD engines
Most CRD engines have a cast iron engine block; versions with an aluminium block are rare. The cylinder head is always made of aluminium. The valve timing mechanism uses a chain or a belt. As a rule, a common rail is used for fuel supply. ECD engines, which are equipped with unit injectors, are an exception. Turbochargers for these engines are usually made by Garrett or IHI.
