‌ Emission compatibility ‌
It meets the Tier 2/Stage IIA to Tier 3/Stage IIIA emission standards for off-highway equipment in Europe and the United States, and supports market access in multiple regions around the world.
Equipped with Holset wastegate technology to optimize combustion efficiency and reduce nitrogen oxide emissions.
‌ ‌ Military-grade reliability ‌
The crankshaft adopts alloy steel forging technology, and the journal is induction hardened, which increases fatigue strength by 30%. ‌
Key components (such as cylinders and camshafts) are modularly designed, the number of parts is reduced by 40%, and the failure rate is lower than the industry average.

Typical applications
Engineering machinery: 1.5-5 ton small excavators, port empty container stackers, municipal tow trucks.
Energy equipment: 30-100kW standby generator sets, oilfield fracturing pump power units.
Special vehicles: airport baggage tractors, cold chain logistics transport vehicle chassis power.
