The Caterpillar C0.5 is a 0.5 L (507 cc, 30.94 cu·in) natural aspirated two-cylinders four-stroke liquid-cooled internal combustion vertical diesel engine, manufactured by Caterpillar Inc. for a wide range of small, off road applications.
The Cat C0.5 engine has a two-cylinders, cast-iron cylinder block, overhead valve design, indirect injection fuel system, 12 volts electric starter motor, and 12 Volts (65 amp) alternator. This engine used a belt-driven coolant pump, coolant temperature switch. The lubrication system consists of a closed-circuit breather, spin-on lube oil filter, lube oil pressure switch, and lube oil sump.
The CAT C0.5 engine produced:
- For auxiliary power and other special applications: 10.3 PS (7.6 kW; 10.2 HP) at 2,800 rpm of maximum output power and 27.0 N·m (2.8 kg·m, 19.9 ft·lb) at 2,800 rpm of peak torque.
- U.S. EPA Tier 4 Final, EU Stage IIIA emission standards: From 11.2 PS (8.2 KW; 11 HP) at 2,800 rpm to 13.9 PS (10.2 KW; 13.7 HP) at 3,600 rpm of maximum horsepower.
