Hino’s N04C Turbo-Diesel Engine Workshop Service Manual

Hino’s N04C turbo-diesel engine offers a class-leading combination of power and torque. The 4.0-litre engine is equipped with a common-rail fuel injection system and Variable Nozzle Turbo (VNT) technology to achieve lower emissions and uncompromised power and fuel efficiency.

Meeting both strict Euro 5 and Enhanced Environmentally-Friendly Vehicle (EEV) emissions standards, the new model’s gains in power, torque and fuel efficiency have been achieved through careful attention to engine design, turbocharger pressures and the high-pressure (common-rail) electronic fuel injection.

The engine features a cooled exhaust-gas recirculation system and closed crankcase ventilation, while the Diesel Particulate Active Reduction System (DPR) system has an 800,000km service interval and an automatic self-cleaning system which begins when the filter is only at 30 per cent of overall capacity.

Injection pressures have been increased and a new intercooler adopted, and the Hino engine has the added reliability of three fuel filters.

Wide cab manual models have 121kW of power at 2500rpm and 464Nm of torque at 1400rpm (N04C-UT), with a six-speed transmission.

Standard cab and wide cab automatic are rated at 110kW and 420Nm (N04C-US).

Standard cab has the choice of five-speed manual or six-speed automatic transmission, while the wide cab auto also has a six-speed transmission.
