Tier IV Interim and CHD
The CHD (Compact Heavy Duty) family of liquid-cooled engines are known for their durability and reliability. They are particularly suited for equipping vehicles that are operated under severe conditions. With its indirect injection (IDI) system, two valves per cylinder, camshaft in the crankcase, setup for a third and fourth power take-off (P.T.O.) and valve gear with gear cascade, this engine is the perfect solution for heavy industrial applications.
The LDW line consists of three models:
Thanks to minor technical modifications, all the engines in the CHD family fully meet EPA Tier IV interim standards. Aspirated models (LDW 1603 and LDW 2204) only required a change in the dynamics of combustion to limit particulate emissions (PM). In addition to this improvement, the turbo version (LDW 2204/T) was equipped with a simple system for recirculating exhaust gasses internally to reduce nitrogen oxide (NOx) emissions. As a result, all the engines in the CHD line meet EPA Tier IV interim and State IIIS standards until the next regulations are issued.
