The “4” in the engine title refers to the number of cylinders and the lack of a “V” describes a four-cylinder design. The “236” in the engine name refers to the total engine piston displacement in cubic inches.
The 4,236 is a four-stroke diesel engine. Total engine piston displacement is 235.8 cubic inches. The diameter per stroke of the pistons is 3.875 by 5 inches, while the compression ratio is 16 to 1. The engine is naturally aspirated and uses a direct injection fuel combustion system. Engine rotation is counterclockwise when viewed from the rear of the engine. The governor uses a mechanical system and the engine uses a heat exchange liquid cooling design. The fuel pump is of a rotary distributor design. The 4.236 uses a 12-volt starter motor and a 65-amp alternator.

The engine weighs 1,100 pounds. The piston firing is in the following order: one, three, four, and two. The installation angle uses a maximum static angle of 17 degrees and provides an additional 3 degree magnification.
The motor can be equipped with a set of four anti-vibration motor mounts. A driveline and oil cooler are also available, as well as a manual oil pump. A water-injected exhaust elbow that is compatible with a 3-inch exhaust hose, as well as a multi-front PTO pulley system is optional. A shaft coupling device and an engine instrument display are available. The instrument panel can display oil pressure, voltmeter, tachometer, low oil warning light and temperature warning light.
