Product catalog summary

Specifications
The 6.420TDI propulsion engine delivers a power output of 235.5 kW (320 hp) at the crankshaft with a displacement of 4.2 liters. It features a 6-cylinder inline configuration with 4 valves per cylinder and operates on a 4-stroke diesel cycle. The bore and stroke measure 94 x 100 mm, and it has a compression ratio of 15.7:1. The engine's rated speed is 3600 rpm, with an idle speed of 700 rpm. It achieves peak torque of 804 Nm at 2400 rpm. The dry weight with TTM50A is 469 kg. The engine base is Toyota, and it uses a direct injection fuel system with a mechanical governor. It is turbocharged with an intercooler and has a closed cooling system with a heat exchanger. The mounting angle is 7° front up or 0° front down. The alternator is 12 Volt, 80 Amp, and it complies with emission standards RCD 94/25/EC and BSO 2.

Technical Description
The engine block consists of 6 cylinders in line with 4 valves per cylinder and a water-cooled exhaust manifold. It includes internal balancers. The fuel system features direct injection with a mechanical governor and a fuel filter with a hand primer. The lubrication system includes a replaceable full-flow oil filter, oil dipstick, and transmission oil cooler. The cooling system is closed with a heat exchanger, gear-driven self-priming raw water pump, coolant circulating pump, and water-cooled exhaust elbow. The electrical system includes a 12V 80A alternator and complete instrumentation with key switch and alarms. The air intake system includes a dry turbocharger and intercooler. Other features include flexible engine mounting.

Optional Equipment & Accessories
Options include complete marine propulsion systems, marine transmission adaptation kits, throttle and shift controls, additional instrumentation, flying bridge extension harness, water boiler systems, stuffing box connections, complete fuel systems, complete exhaust systems, trolling valve, 12V 120A alternator, and a two-pole electrical system.

Rating
The engine is rated for up to 500 annual operating hours with a load factor up to 35%. Full power can be used for no more than 30 minutes out of each 8 hours of operation, with the remaining time at or below cruising speed.

Transmissions
Compatible transmissions include TTM50A, ZF220PL, ZF63, ZF63A, ZF63IV, and ZF80A. Contact a local dealer for more details and availability.
