Unique Drive System
The drive gear design is incorporated into the latest YARMAX diesel engine which will greatly reduce vibration and noise.
Fuel System Technology
Fuel systems assure high efficiency operation. The precision machined and precisely timed injection pump and the direct-injection design leads to lower fuel consumption and reduced tailpipe emissions. The engine meets current and proposed EPA emission standards.
Advanced Noise-reduce Design
The high efficiency muffler system greatly lowers exhaust noise. With the addition of the advanced design air induction system,intake noise is reduced to a low level. The design of the cylinder block, engine cover,and valve drain all combine to reduce engine noise levels.
