RENAULT ENGINE F9Q. In December 1982, the Renault Board proposed a new 1,596 cc (1.6 L) diesel engine with 55 bhp (41 kW; 56 PS) for the Renault 9. Known as "F8M", the new engine was designed by engineer George Douin and his team and broke with tradition by featuring no removable cylinder liners, thanks to advances in metals technology that significantly slow the wear of rubbing mechanical parts. The new 4- cylinder unit adopted an overhead camshaft driven by a toothed belt that also controls the diesel injection pump. A second belt rotates the alternator and water pump, while a vacuum pump located at the rear operates the brake servo. The cast iron block is topped by a light alloy cylinder head featuring Ricardo Comet prechambers. The engine is mounted transversely inclined rearwards 12°. A few months after the release of the Renault 9 Diesel, the Renault 11 was launched in April 1983, the diesel version being introduced in autumn 1983.
