yacht diesel engine light weight stern drive
This engine adopted advanced design theory and design method, combing with the many years turbocharged inter-cooler technology and practice experience to develop unitedly the high speed yacht power, high reliability, lower emission.
Fast speed: High rotation speed running could guarantee the high speed of the yacht, better acceleration.
Reliability: High strengthened crankshaft, enhanced type gantry type cylinder block, inner cooling fuel pipe piston, the development is authorized by China government. Each circle nearly 20 sets of sample engine, three times of design, revising and testing to greatly protect the following volume production safety, reliable running.
Fuel-saving: Turbocharged inter-cooled technology, high press common rail technology application, it makes each milliliter fuel could release superlatively. Lower noise and comfortable: Small vibration, lower noisy, lower emission.
Safety: Water cooled air exhaust pipe, lower temperature and thermal insulation technology, to lower the engine room temperature.
Compact construction and light weight: Module design, light weight materials application, the whole unit engine weight is very light can be 380kg and the good surface looking.
