Hyundai launches workboat engine
Korean engine maker Hyundai has introduced a heavy duty diesel engine aimed primarily at the work and fishing boat markets – writes Dag Pike.
Rated at 500 hp, the L.500 is designed to operate for uninterrupted and unlimited use at full power. This new engine features electronic injectors which allow it to meet the strictest emission standards and to deliver heavy duty power and torque over a wide range of engine speeds.
Based on a 12.7 litre block, the L500 has been developed for reliability by using simplified design. There is a waste gate turbocharger and an integrated oil cooler in the cylinder block. The oil, fuel and seawater pumps are all gear driven rather than using belt drive and the monosteel pistons are gallery cooled. Easy servicing of the engine is assisted by such features as the easily accessible seawater pump and the oil cartridge. Both the air and the oil filters are of the washable and re-useable type and the engine is fitted with an electric oil change pump to facilitate maintenance.
The engine is a four stroke, four valves per cylinder unit with the valves driven by an overhead camshaft. Fresh water cooling is used and the air charge passes through an inter-cooler. The bore and stroke are 130 mm by 160 mm and the engine is designed to produce its maximum torque of 230 kg/m at 1,200 rpm. The maximum rpm is 1,800 and the maximum fuel consumption is 91 litres per hour.
First deliveries of this new engine are now available and this new more powerful engine will supplement Hyundai’s H380, 380 hp engine introduced last year. These new engines are manufactured in a joint venture between Hyundai and Kia Motors that is called Hyundai Seasall.
