Advanced design and sophisticated manufacturing increase its high strength , heavy-duty work ability, using Holset wastegate makes power ability better.
Integrated design block, cylinder heads and other parts , ” a pluripotent ” , reducing the connections, 40% fewer parts than other similar engines, the failure rate is greatly reduced.
High-pressure fuel pump rotor lower fuel consumption , lower noise
