Motorenfabrik Hatz and its North American subsidiary Hatz Diesel Of America, officially launched the second model in it H-Series diesel engine line at ConExpo-Con/Agg. The new 3H50 engine is a 1.5 L, three-cylinder engine that delivers up to 62 hp. Together with the established Hatz 4H50 engines, the 3H50 engines round out the company’s liquid-cooled diesel engine range.
The engine, which will go into series production next year, incorporates the iHACS (intelligent Hatz Advanced Combustion Strategy), which consists of sophisticated combustion chamber geometry, Bosch high-pressure fuel injection technology, minimized friction, cooled exhaust gas recirculation and a charge-air pressure of 25 psi. Designed to meet current and future emission standards, the 3H50 at 25 to 50 hp is engineered to meet EPA Tier 4 interim and EU Stage 3a standards without exhaust emissions aftertreatment and complies with Tier 4 final and EU Stage 3b regulations up to 56 hp with the addition of a diesel oxidation catalyst (DOC), the company said.
The engine is prepared to meet upcoming EU Stage 5 standards with the addition of Hatz’s optiHeat DPF system which is designed to provide an optimum length between two regeneration intervals.
Built to be compact and lightweight, the 3H50TI weighs in at 293 lb. in its Tier 4 interim/Stage 3a configuration and approximately 340 lb. with Tier 4 final and Stage 3b/Stage 5 aftertreatment.
The H-Series engines are also available in the Hatz OPU concept, which can incorporate a range of radiators, tubing and wiring of electronics, all of which is designed to make installation simpler in applications such as hydraulic lifts, hydraulic power units, forestry machinery, drilling rigs and stationary duties such as pumps and generator sets.
