The Toyota 1C is a 1.8 L (1,839 cc, 112.2 cu·in) four-cylinders, four-stroke cycle water-cooled naturally aspirated internal combustion diesel engine, from the Toyota C-family, manufactured by the Toyota Motor Corporation from 1981 to 1992.
The 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 Toyota 1C 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 N·m (12 kg·m, 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 145 Nm (14.8 kg·m; 107.0 ft·lb) at 2,600 rpm of torque.
The breakdown of the engine code is as follows:
- 1 – 1-st generation engine
- C – Engine family
