Fiat 130 - Engine

Engine

Using the "128 type A" motor as a basis, a new crossflow V6 engine, with a 60° vee angle and rubber-toothed-belt driven twin overhead camshafts was developed for the model by Ferrari engine designer Aurelio Lampredi. It became known as the "130 type A" engine with a capacity of 2866 cc and a power output of 140 bhp (104 kW; 142 PS) at 5600 rpm.

The engine was uprated to 160 bhp (119 kW) for 1970, which involved raising the compression ratio from 8.3:1 to 9.0:1, increasing the size of the carburettor choke from 42 to 45 mm and reducing back pressure by extending the portion of the exhaust manifold that used individual pipes on each side of the V format engine. This provided useful performance improvements in a market-segment where relatively new models from Mercedes-Benz and Jaguar north of the Alps were setting an increasingly competitive pace.

In 1971, the "130 type B" engine was introduced, featuring a slightly increased bore (102 mm instead of 96 mm), displacing 3235 cc and producing 165 bhp (123 kW) at 5600 rpm.
