Toyota 1C Engine Specifications
The Toyota 1C is a 1.8 L (1,839 cc, 112.2 cubic inches) four-cylinders,
4-stroke water-cooled naturally aspirated internal combustion diesel
engine, from the Toyota C-family, manufactured by the Toyota Motor
Corporation from 1981 to 1992.
The Toyota 1C diesel engine has a cast-iron cylinder block with 83.0 mm (3.27
in) cylinder bores and an 85.0 mm (3.35 in) piston stroke. Compression
ratio rating is 23:1. The engine has a cylinder head with a
single overhead camshaft (SOHC) and 2 valves per cylinder (8 in total).
This engine was available in the following modifications:
1C is a longitudinally mounted engine. This engine produced 65 PS (48
kW; 64 HP) at 4,700 rpm of horsepower and 118 Nm (12 kgm, 87 ft-lb) at
2,700 rpm of torque.
1C-L is a transversely mounted version of the 1C.
1C-TL is a turbocherged version was installed in the Toyota Camry and
Vista. It produces 73 PS (54 KW; 72 HP) at 4,500 rpm of output power and
