The 1966 Pontiac OHC Six engine was the first US mass-produced vehicle to use a timing belt, [21] [22] while the 1966 Fiat Twin Cam engine was the first mass-produced engine to use a timing belt with twin camshafts. Carmakers began to adopt timing belts in the 1970s and compared to timing chains are less expensive, smaller, lighter, quieter ...
cast aluminium alloy; four valves per cylinder, 16 valves total, low-friction roller finger cam followers with automatic hydraulic valve clearance compensation, timing belt and gear-driven (relay method: belt drives exhaust camshaft from Rear of engine, inlet camshaft is driven at rear of engine by gear from exhaust camshaft) double overhead ...
fully demand-controlled and returnless; – fuel tank–mounted low-pressure fuel pump, Fuel Stratified Injection (FSI): inlet camshaft double-cam driven Hitachi single-piston high-pressure injection pump maintaining a pressure between 30 and 110 bar (440 and 1,600 psi) in the stainless steel common rail fuel rail, four combustion chamber sited ...
Volkswagen use a variator system with two variators, one for each camshaft. Like the Alfa Romeo system, these are electrically-controlled hydraulic units, mounted in the camshaft's timing belt pulley. [11] These systems are fitted to the Volkswagen VR5 and VR6 engines, and also to the W8 and W12 engines.
cast aluminium alloy; two valves per cylinder, single overhead camshaft (SOHC) via toothed belt. fuel system & engine management Solex/Pierburg 30/35 PDSIT carburettor (early), Pierburg 2E3 carburettor (late) DIN-rated motive power & torque outputs 40 kW (55 PS; 54 bhp) at 5500 rpm; 91–94 N⋅m (67–69 lbf⋅ft) at 3200 rpm (ZA/ZP)
The W12 engine is constructed from two VR6 engines mated together at an angle of 72 degrees. Although Volkswagen has not produced a VR4 engine, nonetheless it briefly produced a W8 engine from 2001 to 2004. The largest Volkswagen W engine is the W16 engine introduced on the Bugatti Veyron in 2005. This engine uses an angle of 90 degrees between ...

The Volkswagen EA211 engine (EA = development order), also called modular gasoline engine kit, is a family of inline-three and inline-four petrol engines with variable valve timing developed by Volkswagen Group in 2011. [1] They all include a four-stroke engine and dual overhead camshaft drive into exhaust manifolds. [1]
