Automotive ApplicationsEdit

3 CylinderEdit

HR 392 SOHCEdit

92 mm × 89.2 mm (3.62 in × 3.51 in) bore and stroke, 1.8 L; 108.6 cu in (1,779 cc) straight-three engine, of an OHV pushrod design with two valves per cylinder. The block was cast iron, with an alloy head. It featured a four main bearing crankshaft, a balance shaft, and a Bosch VE3/10 fuel injection pump. A KKK 14 turbocharger was used, with an intercooler for the facelifted 'Nuova 33' of 1990.[1] Although out of production, this was the biggest three-cylinder engine ever made for a car.
