Ford 2713E Engine

The Ford 2713E is a heavy-duty, naturally aspirated 6-cylinder vertical inline diesel engine belonging to the Ford 2700 Dorset Series. Produced in the United Kingdom until its discontinuation in 1984, this highly versatile power unit was engineered for rugged dependability across industrial, agricultural, generator-drive, and marine applications. It features a cast-iron engine block with semi-finished liners and is widely regarded in workshop environments for its simple, robust mechanical architecture that yields high service longevity and straightforward rebuild procedures.

The cylinder head utilizes an overhead valve (OHV) design with two valves per cylinder actuated via conventional pushrods and rocker arms from a gear-driven camshaft. Cylinder Bore: 105 mm (4.12 inches). Piston Stroke: 115 mm (4.524 inches). Total Displacement: 5.950 liters (363 cubic inches).

Fuel System: Fuel delivery relies on a mechanical Direct Injection (DI) configuration. The system incorporates a multi-cylinder mechanical fuel injection pump driven by the engine timing gears, paired with a mechanical governor to manage engine speed. Fuel is pressurized and delivered through steel high-pressure lines to individual multi-hole injectors positioned vertically above the pistons, spraying directly into the combustion chambers to achieve clean compression ignition.

The engine uses a full-pressure lubrication circuit powered by a positive-displacement oil pump driven internally off the gear train. The circuit distributes oil through a primary gallery supplying the main bearings, connecting rod journals, camshaft bearings, and overhead rocker assemblies. Oil filtering is handled by a spin-on element, supported by front and rear crankshaft lip seals to ensure system integrity.

Engine cooling is managed via a high-capacity, pressurized liquid-cooled circuit. A belt-driven centrifugal water pump forces coolant through the cast-iron cylinder block jackets and cylinder head passages. Temperature regulation is maintained by a mechanical thermostat opening into an external radiator or, in marine applications, a heat exchanger / keel-cooling circuit combined with a dry or wet exhaust setup.
