Douvrin Engine - 2.1 Diesel

2.1 Diesel

The 2.1 L (2068 cc) Diesel version was derived from the 2.0 L petrol version by a bore reduction from 88 to 86 mm (3.4 in) and a stroke extension from 82 to 89 mm (3.5 in). Cast-iron cylinder liners were used to withstand the higher cylinder pressure of Diesel combustion. The cylinder head was of course specific and was a Ricardo-type prechamber design fed by a mechanically controlled fuel pump. This engine was only used by Renault in three versions:

• normally aspirated 8-valve, 65 PS (48 kW; 64 hp), from 1980 to 1992
• turbocharged 8-valve, 88 PS (65 kW; 87 hp), from 1982 to 1992
• turbocharged 8-valve with variable-nozzle turbocharger, 92 PS (68 kW; 91 hp), from 1990 to 1996

Reliability of all Diesel versions has been outstanding, surpassing even that of the 2.0 L petrol version.
