North American Premiere of the New Hatz 3-Cylinder Diesel Engines
Hatz presented its new 3H50 engines at CONEXPO-CON/AGG 2017. Developed for compact applications, the first 3-cylinder models will go into series production in 2018. The 3H50 will expand the Hatz H-series which already includes the 4-cylinder 4H50.
The 1.5 l Hatz 3H50 will replace engines with displacements over 2.5 l in many applications where its performance and packaging compare favorably with current engines. At the same time the fuel consumption values are significantly reduced thanks to iHACS (intelligent Hatz Advanced Combustion Strategy) that features a sophisticated combustion chamber geometry, Bosch injection technology, minimized friction and a charge air pressure of 25 psi. All this in a package measuring less than 653 x 612 x 650 mm (LxWxH) including engine mounted aftertreatment.
Following the family concepts, the various 3H50 models are also orientated on the currently valid and future emission standards.
The 133 kg lightweight Hatz 3H50TI does not need any exhaust emission aftertreatment at all. Nevertheless, the engine achieves compliance with the EU Stage IIIA and US EPA Tier 4 interim standards in the power range from 25 to 50 hp. Avoiding sulphur sensitive components, the use of diesel fuel with up to 5000 ppm sulphur is no problem. Higher ambient temperatures in comparison to other 3H50 models are also possible. With a maximum torque of 146 lbf ft @ 1600-2200 rpm and up to 62 hp, the Hatz 3H50TI is the top performer of the 3-cylinders.
The Hatz 3H50TIC was primarily developed for the U.S. market and Canada as well as some Asian countries. In order to ensure compliance with emission standards, the proven combination of an external gas recirculation (EGR) and a diesel oxidation catalyst (DOC) reduces substances potentially harmful to the environment to the required level without the need of a diesel particulate filter (DPF). Therefore the engine still achieves up to 56 hp and provides a torque of 136 lbf ft. The additional components add approximately 21.3 kg of extra weight. The requirements of the new EU Stage V emission level require the use of a DPF. The Hatz 3H50TICD is thus optimally prepared for future emission standards while performance is the same.
The Hatz OPU concept is ideal for equipment manufacturers who have less capacity for specification of radiators, tubing and wiring of electronics, due to a tremendous ease of installation. The main application areas are primarily working machines such as hydraulic lifts, hydraulic power units, forestry machinery, drilling rigs and stationary applications such as pumps and generators. All H-series engines are also available as an OPU version. The customer only needs to connect the fuel supply, control box and battery.
