PSA XD engine

The PSA XD engine, also called the Indenor XD, is a family of four-stroke diesel engines with in-line four cylinders and capacities from about 1.8 to 2.5 litres, developed and produced by the Indenor company between 1963 and 1992. It has a cast iron block, an aluminium cylinder head, a five-bearing crankshaft and a lateral camshaft that works eight overhead valves through rods and rocker arms, driven by a timing chain except on the XD85 and XD88, which use a cascade pinion drive. The family grew out of the TMD 85 engine of the 1959 Peugeot 403 Diesel, and the number in each type name gives the bore in millimetres. The types run from the XD85 and XD88 through the XD90, XD2 and turbocharged XD2S to the XD3, XD3T and XD3TE, and a six-cylinder inline version was built alongside. Peugeot used it in the 404, 504, 505 and 604, and it also powered the Ford Granada and Sierra, the Talbot Tagora, Mahindra and Leyland vehicles and the UAZ jeep, as well as boats, tractors and generators.
