CRD engines: what it stands for and its performance parameters

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.

The air mass flow sensor gets soiled prematurely. Usually it is caused by tearing of the membrane of the crankcase ventilation valve.ENJ
The thermostat has a relatively short lifespan.ENJ; EXF
The crankshaft position sensor sometimes breaks down.EDJ; ENJ
The turbocharger has a short lifespan.ENS; EXL; ECE; ECD; ENR
The connector of the fuel filter heater loses its tightness often.ENS; ENR
The EGR valve quickly builds up carbon deposits and gets jammed.ECD; ECE
Turbocharger hoses are prone to cracking.EXF
The valve of the engine oil cooler gets broken, leading to oil starvation.EXF
The intake manifold flaps often jam.EXL; EDJ
The quick release connectors of the fuel system lose elasticity, leading to its airlocking.EDJ
