The Caterpillar C1.5 is a 1.5 L (1,496 cc, 91.29 cu·in) natural aspirated or turbocharged three-cylinders four-stroke liquid-cooled internal combustion vertical diesel engine, manufactured by Caterpillar Inc. for general-purpose applications.
The Cat C1.5 engine has a three-cylinders, cast-iron cylinder block, overhead valve design, indirect injection fuel system, 12 volts electric starter motor, and 12 Volts (65 amp) alternator and glow plug starting aid. This engine used a belt-driven coolant pump and 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.
