Robinhood Posted February 28, 2016 Share Posted February 28, 2016 ...for 2005, the engine is likely to be a 2.2HDi PSA 4HY (2179cc). As you detail, this has a cam belt, not chain, and is not the same as the Ford Puma derived engine used in the later versions of the Boxer and Relay.

paulmold Posted February 28, 2016 Share Posted February 28, 2016 If you have time to read this it may help or it may totally confuse you.. https://en.m.wikipedia.org/wiki/Ford_Duratorq_engine Or you could ask Wildax, there no better maker for customer service.

disco duck Posted February 28, 2016 Author Share Posted February 28, 2016 Main article: PSA EW/DW engine looks like you found it DW12 Continuing the Ford/PSA diesel engine joint-venture[citation needed], these straight-four engines are again sold under the Duratorq TDCi name by Ford, and as the HDi by Citroën and Peugeot. A development of the existing DW10/DW12 engine[citation needed], the new engines have a traditional belt-driven system, moving away from the chain-driven camshafts of the previous generation (Puma) TDCi engines. Both engines utilise common rail diesel technology and are the result of the fourth phase of the cooperation between PSA and Ford (initiated in 1998)[citation needed]. Both engines utilise all-new, third-generation common rail injection systems. The 2.0 engines utilising a system from Siemens and the 2.2 a system from Bosch. In both systems the injection pressure has been increased to 1800 bar. This higher injection pressure, associated with new piezo-electric injectors in which each nozzle is equipped with seven apertures (instead of five previously), allows the number of injections to be multiplied (potentially up to six per cycle) and ensures meticulous uniformity of the diesel injection spray pattern. As a result of this optimised air/diesel mix, combustion is more complete and more uniform, and therefore reduces emissions at source. rgds.dd Link to comment Share on other sites More sharing options...
Derek Uzzell Posted February 29, 2016 Share Posted February 29, 2016 As Robinhood said, the motor will be a PSA 4HY unit. This is a Peugeot-built motor - hence the PSA (Peugeot SA) designator - not a Ford-built motor. Link to comment Share on other sites More sharing options...
Robinhood Posted February 29, 2016 Share Posted February 29, 2016 ....yes, and this Peugeot engine was the basis for the further and later (Ford) development used in Ford cars as in the above link. This was all reversed in the later post 2006 Relay/Boxer, where the different Ford-Puma based 2.2 chain-cam engine (as used in the Transit) was adopted and adapted by Peugeot and Citroen for the Boxer and Relay. Confusing, ain't it! Link to comment Share on other sites More sharing options...
