Our two-cycle engine is more responsive and productive with a lower cost single gear driveline. A four-cycle engine is restricted to operate in a very narrow range, compromising productivity and fuel consumption, requiring a second gear in the driveline.
Our two-cycle 710 engine is the most responsive in the world. With generator sets, testing proves our 5,000 horsepower 20-cylinder engine is able to accept full load in one step and recover speed in two seconds. Similar testing in marine applications has demonstrated acceleration from idle to full load in less than 11 seconds. By firing each cylinder once per revolution and benefiting from plentiful combustion air through our unique clutched turbo-changer design, the 710 engine is unique in its ability to smoothly accept load at any engine speed and at a rate no other medium speed engine in the world can match.
We are the world leader in manufacturing two cycle, medium speed engines for marine, drilling, power generation, and locomotive markets.
