Product catalog summary

Specifications:
The 8F21 common rail diesel engine features an 8-V type cylinder configuration with a bore and stroke of 127 x 165 mm, resulting in a total displacement of 16.7 liters. The engine rotates counterclockwise and has an idle speed of 650 RPM. It includes a 14-inch flywheel and an SAE 1 flywheel housing. The engine is equipped with a two-stage turbocharging system and is designed for various duty applications ranging from continuous to high performance.

Performance and Fuel Consumption:
The engine offers different power ratings for various applications: P3 (809 kW at 2300 RPM), P4 (919 kW at 2300 RPM), and P5 (1000 kW at 2300 RPM). Fuel consumption varies slightly across these ratings, with optimum values ranging from 204 to 211 g/kWh. The engine is suitable for intermittent, light, and high-performance duties, with specific applications such as seasonal passenger vessels, fishing boats, and private pleasure boats.

Engine Components:
The engine block is made of cast iron with separate cylinder heads and replaceable valve guides and seats. It features a steel forged crankshaft with five bearings and lube oil-cooled light steel pistons with three high-performance piston rings. The cooling system includes a two-stage circuit with a built-in HT thermostatic valve and a high-efficiency tubular heat exchanger.

Fuel and Lubrication Systems:
The engine uses a common-rail electronic injection system with a high-pressure pump and shielded high-pressure injection rail and pipes. It includes duplex-type fuel oil filters and an external fuel pre-filter with a water separator. The lubrication system features full-flow lube oil filters and a fresh water-cooled lube oil heat exchanger.

Electrical System:
The engine operates on a 24V DC insulated electrical system with an electrical starter and a 200A battery alternator.

Reference Conditions:
The engine's performance is based on reference conditions of 25°C ambient temperature, 100 kPa barometric pressure, and 30% relative humidity. It complies with classification societies' maximum temperature definitions without power derating, even at ambient temperatures of 45°C and raw water temperatures of 32°C.
