Design

The designs optimize fuel injection and intake porting to improve combustion performance, particularly low-temperature combustion stability though lean air-fuel rationing.

This ensures that we satisfy the world’s strictest exhaust emission standards while providing the smooth, quiet and efficient power for which Hyundai SeasAll is becoming known.

Cast iron cylinder block

Durability and Reliability

The use of Compacted Graphite iron (CGI) for the cylinder block gives Hyundai Seasall engines several advantages. The CGI block is lighter and quieter than conventional grey cast iron and demonstrates at least 85 percent higher tensile strength, 45 percent higher stiffness and approximately double the fatigue strength of iron and aluminum. It lasts longer than even we ever expected. this technology is a prime example of the innovation and improvement we bring to the marine engine industry. with Hyundai Seasall, you are on the cutting edge.

Performance

The S270 features leading edge diesel technologies for a quieter, cleaner, greener, meaner inboard engine

Powertrain technology

Hyundai Powertrain Technology, already proven in a full range of modern diesel engines, now brings this exceptional performance and reliability to the marine market.

Engine

At the core of Hyundai Seasall’s Advanced diesel technology is a focus on stability, performance, fuel efficiency and reliability: key elements which make their engines world class.
