Douvrin engine

This engine had an aluminium alloy block with cast iron liners, and an aluminium alloy head with one overhead camshaft driven by belt. Its displacement varied from 1995 to 2165 cc. This engine should not be confused with the PSA-Renault X-Type engine whose displacement varied from 954 to 1360 cc and had a gearbox integrated to the block. The Douvrin engine on the contrary, had a conventional (external) gearbox setup, and was longitudinally or transversely mounted depending on car model. ==2.0==

The was an oversquare design with a single belt driven overhead camshaft, an bore and stroke. Applications PSA Renault It was produced in a variety of configurations for Renault: • naturally aspirated 8-valve, single-barrel carburetor, , from 1978 to 1993 • naturally aspirated 8-valve, double-barrel carburetor, , from 1977 to 1992 • naturally aspirated 8-valve, multipoint, Bosch L(U/E) Jetronic fuel injection, ( with catalytic converter), from 1984 to 1989 (Catalytic converters required in North American market only.) • naturally aspirated 8-valve, multipoint, BENDIX ECU-driven, fuel injection, ( with catalytic converter), from 1989 to 1996 • naturally aspirated 12-valve, multipoint fuel injection, , ( with catalytic converter), from 1989 to 1996 • turbocharged 8-valve, multipoint fuel injection, ( with catalytic converter), from 1987 to 1993 (Catalytic converters fitted IAW EC directive in MY '89; now referred to as EURO III). • Renault 18[1] • Renault 20 • Renault 21 • Renault 25 • Renault Espace • Renault Fuego • Renault Safrane • Renault Trafic Others • SIMI Cournil SCE15/25 • Auverland SC 11/200/250 ==2.2==

The version was derived from the by a stroke extension from , making it an undersquare design. Most parts, including the cylinder head, were identical to those of the 2-liter unit. This engine proved as reliable as its 2.0-liter counterpart. It is often confused with the somewhat similar 2.2 litre Chrysler Type 180 engine, which displaced Applications PSA Renault Renault offered the 2.2 in fewer configurations than the smaller version: • normally aspirated 8-valve, double-barrel carburetor, , from 1977 to 1992 • normally aspirated 8-valve, multipoint fuel injection, ( with catalytic converter), from 1983 to 1996 • normally aspirated 12-valve, multipoint fuel injection, , from 1989 to 1996 • Renault Espace • Renault Fuego • Renault 18 • Renault 20 • Renault 21 • Renault 25 • Renault Master • Renault Medallion • Renault Safrane Others • 1987–1989 Eagle Medallion • 1983–1992 Winnebago LeSharo (built on Trafic chassis and cab) • 1983–1992 Itasca Phasar (built on Trafic chassis and cab) == 2.1 Diesel==

The Diesel version was derived from the petrol version by a bore reduction from and a stroke extension from . Cast-iron cylinder liners were used to withstand the higher compression ratio of Diesel combustion. The cylinder head was a Ricardo-type pre-chamber design fed by a mechanically controlled fuel pump. This engine was only used by Renault in three versions: • normally aspirated 8-valve, , from 1979 to 1992 • turbocharged 8-valve, , from 1982 to 1992 - 1),2) • turbocharged 8-valve with variable-nozzle, , from 1990 to 1996 :- Garrett T2 turbocharged 8-valve version was fitted by AMC-Renault in the 1984-1987 Jeep Wagoneer, Cherokee and Comanche models :- Garrett T3 turbocharged 8-valve version was fitted by AMC-Renault in the 1983-1986 Winnebago Lesharo/Itasca Phasar, based on the Renault Trafic I 'P'latform chassis, albeit only in FWD, LWB designs. • Renault 18 • Renault 20 • Renault 21 • Renault 25 • Renault 30 • Renault Fuego • 1992–1996 Renault Safrane • Renault Espace • Renault Trafic • Renault Master • 1983–1986 Winnebago LeSharo (built on Trafic chassis and cab) • 1983–1986 Itasca Phasar (built on Trafic chassis and cab) • Jeep Cherokee (XJ) • Jeep Comanche == See also ==
