Specifications
The T4.230 propulsion engine delivers a power output of 169.1 kW (230 hp) at 3600 rpm. It features a 2.982-liter displacement with a 4-cylinder inline configuration and 4 valves per cylinder. The engine operates on a 4-stroke diesel cycle with a bore and stroke of 96 x 103 mm and a compression ratio of 15:1. It achieves peak torque of 573 Nm at 2000 rpm and has a dry weight of 350 kg. The engine is based on a Toyota platform and includes a direct injection fuel system with a high-pressure common rail that is electronically controlled. The air intake is turbocharged with an intercooler, and the cooling system is closed with a heat exchanger. The engine can be mounted at a 7° angle front up or down and includes a 12 Volt, 100 Amp alternator. It complies with RCD 94/25/EC, EPA marine Tier 3, and BSO 2 emission standards.

Technical Description
The engine block consists of 4 cylinders in line with dual overhead camshafts and a water-cooled exhaust manifold. It includes internal balancers for smooth operation. The fuel system features a common rail injection system, a fuel filter with a hand primer, and an integrated fuel cooler. The lubrication system includes a replaceable full-flow oil filter, an oil dipstick, and a transmission oil cooler. The cooling system is equipped with a gear-driven self-priming raw water pump and a coolant circulating pump. The electrical system includes a 12V 100A alternator and complete instrumentation with key switch and alarms. The air intake system features a dry turbocharger and intercooler. Additional features include flexible engine mounting and optional equipment such as marine propulsion systems, transmission adaptation kits, and additional instrumentation.

Rating
The engine is rated for up to 500 annual operating hours with a load factor up to 35%. Full power operation is limited to 30 minutes per 8-hour period, with the remaining time at or below cruising speed.

Transmissions
