World’s New Standard Engine for Marine & StationaryWorld’s New Standard Engine for Marine & Stationary

Hyundai ’s Own Developed. . . HiMSEN Engine

The Most Practical Engine......for the 21st Century

Hi-Touch Medium Speed EngineA Well Proven Design with Practical Applications

...for higher performance

...for higher reliabilityA Simplified Structure with minimum components

...for easier maintenance

...for lower initial and operating cost

HHI has developed its own specially designed HiMSEN engines incorporating its valuable experience and technical know-how acquired in manufacturing diesel engines for over two decades. The theme “Humans, Technology, and the Future” was synthesized in this new engine. Also, “HiM” means “power”, and “SEN” means “strong” in Korean.The Hi-Touch concept was introduced to make this truly innovative engine a reality for humanity. It was designed to be “the Most Practical Engine” in regards to both humans and the environment. Through HYUNDAI’s accumulated technology and experience, this new challenge has beensuccessfully realized. HHI also has received certificates of New Technology(NT) and Excellent Machine,Mechanism & Materials(EM) for the HiMSEN engines from the Ministry of Commerce, Industry & Energy, Korea.Thus, the HiMSEN is a highly advanced product that shows HYUNDAI’s deep respect for its customers and the environment.

KEY FEATURES

HiMSEN ENGINE4

The amount of NOx emission depends on the engineoperating condition, typically high combustiontemperature and specific fuel oil consumption. A newengine shall be optimized to meet the customer‘sspecific requirements. However, an engine in servicealso can be optimized further regarding NOx emission,if needed. In this case, trade off with SFOC might beconsidered as follows.

HiMSEN is designed for environment-friendly engineand satisfies IMO NOx emission limit with low fuelconsumption and nearly smokeless operation even atidle load.Typical exhaust compositions in volume ratio at full loadare as follows;

Nitrogen N2 approx. 75%Oxygen O2 approx. 13%Carbon Dioxide CO2 approx. 5%water(Vapour)H2O approx. 6%Argon Ar approx. 1%Soot, Ash, NOx, CO, HC, etc.

The remaining is little in amount but ecologicallycritical. Therefore, a careful attention is required for thetreatment of fuel oil and engine operating conditions.If there is no special requirements from customerregarding the exhaust gas emission, HiMSEN Gensetshall be delivered with optimized performanceconditions fulfilling the IMO limit value of NOx emission.Therefore, it is strongly requested to contact the enginemaker if there is any further requirements regardingexhaust gas emission or special operating conditions.

Measurement of NOx Emission

NOx emission from Generator Engine Test Cycle D2 in accordance with ISO 8718-4 and IMO NOx Technical Code.

General NOx Emission

Better fuel consumption and NOx emission Better starting and low load performance

A Higher Stroketo Bore Ratio provides . . . ready for current economical considerations

as well as future environmental requirements.High Stroke to Bore Ratio(320/210=1.52)High Compression Ratio(=17)High Combustion Pressure(max. 200 bar)High Turbocharging Efficiency(Pscav. 3.8 bar)Optimized Cam Timing(Miller Timing)High Fuel Injection Pressure(max. 2,000 bar)

Smart Cooling Water Control(Optional)The HiMSEN engine has a unique cooling water system which is incorporated into the Feed System Module.This is another benefit derived from Hi-Touch designs that maximize a customer’s satisfaction as well as takethe environment into consideration.

Cold combustion air can be heated by air cooler with high temperature(H.T.) cooling water, which insures engine startups in any cold conditionand also reduces smoke to invisible level even at idle load operation withheavy fuel oil.

A simple and smart design of Flow control valve can be incorporated in air cooler cover and enables easy Change-Over of LowTemperature(L.T.) and High Temperature(H.T.) cooling water flow.
