Besides the already existing water-cooled Hatz 4H50 engines there also will be three-cylinders available in the future. For an optimal combustion process, best operating characteristics and reduced emissions they are also equipped with the Bosch common rail technology – maximum injection pressure 1800 bar – similar to the successful four-cylinders. For the first time this system is used in an off-highway diesel engine with three-cylinders. Thanks to the turbo charger and the intercooler the engines have a maximum torque of 185 newton meters (at 1600 to 2000 revolutions per minute) and a maximum power of 42 kilowatts. This all requires an installation space of a quarter of a cubic meter only.
With a capacity of 1.5 litres and a maximum speed of 2800 revolutions per minute this three-cylinder engine sets standards. Furthermore, an additional power-take-off is added to the H-family with this engine.
Following the family concepts, the various three-cylinder versions are also orientated on the currently valid and future emission standards. The Hatz 3H50TI does not need any exhaust after treatment and reaches the standards EU Stage IIIA and EPA Tier 4 interim in the power range 19 to 37 kilowatts.
The Hatz engine 3H50TIC in particular is designed for the US market, Canada and some Asian countries. In order to comply with the exhaust emission standards EPA Tier 4 final (19 up to 56 kilowatts) and EU stage IIIB (37 to 56 kilowatts), a combination of external exhaust gas recirculation (EGR) and diesel oxidation catalyst (DOC) guarantees the necessary reduction of exhaust emissions. Both engine variants will extend the Hatz engine product range from 2018.
“At Bauma, we will present the EU stage V solutions Hatz 3H50TICD and 4H50TICD which will be launched in the market well before the introduction of the new exhaust emission legislation in 2019, says Wolfram Hatz, Commercial Managing Director at Hatz. “Field tests with customers of the H series who will use the new Stage V engines from 2019, have already been carried out.”
