Description
At the beginning of the Seventies, engines with more than 2 valves per cylinder were almost exclusively intended for racing. On the production models there was practically no trace of it. In June 1973, the presentation by the English company Triumph of the Sprint version of the Dolomite sedan, exhibited two years earlier at the London Motor Show, caused a sensation, destined to better compete on the market with cars such as the Alfa Romeo Alfetta and the BMW 2002. The Triumph Dolomite Sprint was equipped with a 1, 998 cc single-cam 4-cylinder with 129 HP (95 kW) developed by the designers led by Charles Spencer King: in practice, the first mass-produced multi-valve engine (22, 941 examples until 1980). Inside the light alloy cylinder head, a single chain-driven camshaft controlled all 16 valves using just 8 cams. The intake valves were in fact controlled directly by cup tappets, while the exhaust valves were operated by rocker arms. An ingenious solution that earned Triumph the Design Council award in 1974. Another peculiarity of the Dolomite Sprint was the 4-speed manual gearbox with electrically controlled overdrive on third and fourth. The Triumph Dolomite Sprint also boasts a good sporting CV. From 1974 to 1978 he regularly competed in the competitive British Touring Car Championship, winning it in 1975 with Andy Rouse.
Here we find a completely restored example of the mechanics and bodywork. Car still running in and customizable.
