Im doing a project for your school and you were woundering what kinds of differences there are between Dodge Chevy and Ford diesel pickup Trucks?

Dodge uses the Cummins 6bt turbo diesel, which is a medium duty engine and built to last. Up until 2008, Dodge used the 5.9L version of this engine, which has been in use since the introduction of the cummins to the Dodge line of pickups. There were 4 different generations of this engine used all with there own differences, mainly being the type of fuel injection used. Until 1998, they used all mechanical injection with two different pumps. The first pump was the Bosch VE fuel pump which was used until 1994 when they changed to the Bosch P7100 which is a very desirable pump for the aftermarket/performance enthusiast. They also used a 12 valve head design during these years. In 1998 they switched to an electric fuel injection pump and a 24 valve head design. These engines used a Bosch VP44 fuel injection pump that, if not properly supported, would get burnt up very easily if it was starved of fuel. In 2003, they kept the 24 valve head design and went to common rail injection and used the Bosch CP3 fuel pump to achieve the fuel pressured needed for the common rail system. In 2008, the bumped up the displacement to 6.7L in order to comply with new federal emissions. Ford uses the Powerstroke, which is made by Navistar. The 7.3L Powerstroke is arguably the best engine of the Powerstroke family which includes the 6.0L and the 6.4L. The 7.3L and the 6.0L used a HEUI (Hydroelectronic Unit Injection) system. In 2008, they made the switch to common rail with the 6.4L and also made use of a twin turbo system. The 6.4L is also the new emissions friendly Powerstroke. General Motors (Chevy and GMC) use the Duramax 6.6L engine. It is designed by Isuzu which is a branch of GM and has had the same displacement since its introduction in 2001 or 2002 (unsure of what year). It is an engine that is very capable of making quite a bit of power with few modifications and is taking over some classes of the diesel motorsports world, which until recently has been ruled by the Cummins powered Dodges. Now Duramax and Cummins powered trucks a very evenly matched while the Powerstroke still has some work to do to become reliable at the power levels the other two can achieve with relatively little work/money.
