2.2 HDi engine (Peugeot) - opinion, problems and malfunctions

2.2 The HDi engine has 4 cylinders, 16 valves, direct injection common rail, floating flywheel clutch, particulate filter, variable geometry turbocharger and belt as drive. It is available in 7 different variants: 130, 136, 156, 170, 173 and 204 horsepower.

The first 2.2 HDi appeared in 1994 and stood out with its complicated construction. Six years later, the technology was updated by installing common rail electromagnetic injectors, which are suitable for repair, power increased from 130HP to 156HP. Six years later (in 2006) they were installed piezo injectors which on the one hand, are fast and good due to the precise amount of fuel injected, and on the other hand are not suitable for reparation, which in case of failure is associated with expensive replacement. Then the power was increased to 170 hp, which is associated with the use of another turbocharger. The last modification was made in 2010 and was mainly related to the addition of an additional 34 hp (204 hp in total) through changes in the injection system. It is important to add that the system is back one turbine with liquid cooling.
