L Building a better future- 'Global Leader HiMSEN Engine Hi-touch Marine & Stationary ENgine / HYUNDAI I ENGINE & MACHINERY HEAVY INDUSTRIES CO..LTD.

HiMSEN family has been successfully launched into the market since 2001 thanks to support and cooperation from many owners, shipyards and classification societies. We would like to express our sincere gratitude to the everyone involved in this enterprise. And we hope that you have good business with our HiMSEN engines.

Introduction The HiMSEN H25/33V engine has been developed based on common philosophy of HiMSEN engine with smart, simple and robust. And the new engine has same bore/stroke and design concept as the current H25/33 in-line engine which is well proven in the market. The high power density contribute to easy and space-saving marine and stationary applications. The most advanced Hi-touch technologies are applied in this engine so that the engine has the excellent performance, low fuel consumption and low emission and so on. HiMSEN H25/33V medium speed engine marks the birth of a new era in...

Emission Control Technology IMO Tier II technologies The HiMSEN H25/33V engine has countermeasures to meet IMO Tier II regulations with advanced simulation and measurement by using of enhanced miller timing and optimized combustion. The enhanced miller timing with new turbochargers which has higher pressure ratio enables to get benefit in SFOC and lower combustion temperature which is critical in formation of NOx emission. Furthermore, controlled combustion with optimum combination of the piston bowl shape and F.O Nozzle’s specification helps to reduce NOx emission.

H25/33V IMO Tier III technologies HHI is already preparing many measures for IMO Tier III. Some of them have already been developed such as Selective Catalytic Reduction (SCR) and Scrubber. Newly developed SCR can reduce NOx emission by upto 95% to meet IMO Tier III regulation. Optimized application depending on customer’s requirement is possible including whole installation, performance and engine with low cost and satisfaction. Exhaust gas scrubbing is an alternative solution for high sulphur content fuels to reduce SOx emissions, and HHI can supply the best Scrubber in the world market....

Engine Block The engine block is made of monoblock cast iron and has the combustion air chamber and lubricating oil channel. There is no need for maintenance normally except for cleaning in side air chamber and outside. And also this is of stiff and reliable to internal and external forces. The main bearing and main bearing cap for the underslung crankshaft are carried in heavy duty supports tightened hydraulically by two vertical main bearing studs and two horizontal side studs. There are covers for maintenance and access to the crankshaft including connecting rod and camshaft with swing...

H25/33V Camshaft The camshaft is of a split type for each cylinder. And each camshaft is jointed by screws. Each piece of camshaft has a fuel cam, an intake cam and an exhaust cam. The surface hardening is done for the each cam profile. Furthermore, the fuel cam with high load is located very close to the camshaft bearing. The gear wheel for driving the camshaft as well as the gear wheel for connection of governor drive are mounted on the flywheel side. The extreme miller timing for intake cam has been applied to reduce NOx emissions. Piston & Piston Rings The piston is of composite type...

Front End Block The front end block is located on the free end of the engine. Pipes for cooling water and lubricating oil system as well as pumps are modularized to simple casting structure. The modularized front end block provides the direct accessibility and the easy maintenance for auxiliary parts. Lub. Oil Filter Front End Block H.T. Thermo V/V L.O. Thermo V/V L.T.C.W. Pump H.T.C.W. Pump Air and Exhaust Gas System The new generation turbocharger with high compression ratio, applied for enforced international environment regulations, IMO NOx limit.
