Product catalog summary

Specifications
The T4.270 propulsion engine delivers a power output of 194.9 kW (265 hp) at the crankshaft with a displacement of 2.982 liters. It features a 4-cylinder inline configuration with 4 valves per cylinder and operates on a 4-stroke diesel cycle. The engine has a bore and stroke of 96 x 103 mm and a compression ratio of 15:1. It achieves a rated speed of 3600 rpm and an idle speed of 700 rpm, with peak torque of 660 Nm at 2000 rpm. The dry weight of the engine is 350 kg. It is based on a Toyota engine and uses 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. It includes a 12 Volt, 100 Amp alternator and 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. 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, complete fuel systems, complete exhaust systems, and trolling valve.

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
Available transmission options include shaft line models TTM50A and ZF63A, and stern drive models Bravo X One, Bravo X Three, and Bravo X Two.

Performance Curves
The performance curves indicate power at the crankshaft and torque at various RPMs, as well as fuel consumption at calculated propeller load.
