This engine has been fitted in various forms to many Peugeot and Citreon models, ranging from the 205/405/306/405/406/605/Partner to Berlingo/XM etc.

Some are equipped with turbos, others not.

The 1.8L version of this engine is not recommended to be run on bio-fuels as it has the Lucas-CAV injection pump, the reason it is not recommended to run biofuel is because the fuel pump has different bearings/seals in it and they seem to be easily damageable and the pump seizes up.

Fuel Delivery

If the engine is fitted with any of the Bosch VE / VE derived pumps its fine, presumably they used a different material for the bearings in this pump. This engine has a built in fuel pre-heating system by means of a fuel swirl chamber built into the engines thermostat housing which can greatly benefit anyone using biofuels

The Bosch AS3 VP20 fuel injection pump, found on the later Peugeot 406/605 model, but same engine, can be adjusted to provide better running by means on electronics.

The engines that use a Bosch VE injection pump to delivers fuel through pintle nozzle fuel injectors are fitted with various add on modules depending on age and application.
