PRV engine

The PRV engine is a six-cylinder V- engine, which was manufactured from 1974 to 1998.

In 1966, Peugeot and Renault formed a consortium to develop a V-engine with eight cylinders. 1971 Volvo came to the consortium and completed to the PRV name.

However, the first oil crisis in 1973 restricted the market for 8- cylinder engines a strong. The motor has been reduced to two cylinders in 1974 brought as a six -cylinder V- engine to the market.

A prototype of the 8- cylinder engine has been maintained at the factory and is also shown in guided factory tours.

Since the cylinder bank angle was maintained at 90 ° ( firing order 1-6-3-5-2-4 ) and opposed cylinder used a common crank pin, an unusually harsh for a six cylinder engine running condition resulted. Only in 1985 a firing interval was introduced, which had a smoother running result. However, Volvo began to withdraw from the consortium and future vehicles equipped from 1990 with a largely self-developed series engine.

Except for the marks of the consortium members of the PRV engine was popular due to its relatively compact design also in sports cars manufacturers such as Alpine, De Lorean or venturi and came in some cars Lancia used.

The engines were initially fitted with a two- carburetor system consisting of a single Solex carburetor 34TBIA and a double carburetor Solex 35CEEI and performed in this configuration 136 hp. Starting in 1977, a version with Bosch K -Jetronic fuel injection was available and there were 144 hp achieved. Talbot increases in Tagore in 1981 with unchanged engine displacement with changes to the piston and cylinder head by means of two Weber carburetors triple the power to 166 hp.

The PRV engine was further developed. The different providers changed among other things the displacement (initially at Peugeot among others 2664 cc (504 Coupé/604 ), later there in 2849 cc ( 505), in 605 Peugeot achieved as much as Renault Safrane and Espace in 2963 cm ³). Read this development is due to the different engine types (with Peugeot: ZM112, ZMJ140, ZNJK, ZN3J and ZPJ or ZPJ4 ). Until the cessation of production in 1998 a total of 970 315 pieces were manufactured.

In the former PRV "La Française de Mécanique " in Douvrin have since been inter alia V6 engines with 60 - degree cylinder angle for Renault and PSA Peugeot Citroën produced.
