Hatz Diesel introduces the four-cylinder engine 4H50TIC, the first in the company's new H-Series. The 2-liter diesel engine offers extremely low emission values, performance and fuel efficiency in the 37 to 56 kW class.

  • Offers reduced size and weight while maintaining high performance and excellent exhaust gas values
  • Achieves maximum output of 55 kW and weighs just 173 kg
  • Meets EU 97/68 Stage IIIB and EPA Tier 4 Final emissions limits
  • Exhaust aftertreatment requires just a robust diesel oxidation catalyst (DOC), which in contrast to a diesel particulate filter (DPF) is maintenance-free and built for a lifetime
  • DOC works without any electronics
  • Use of DPF is not necessary due to the reduction in particulate matter (PM) during the combustion process, but can be added as an option based on regional and local requirements
  • Can be individually adjusted to any application due to electronic control
  • Compact design enables integration into existing applications
  • Fans and the oxidation catalyst can be installed in different mounting positions, providing more flexibility during set up
  • Includes starter protection integrated into the control unit
  • Maintenance-free hydraulic automatic valve adjustment system ensures there is no need to interfere with the fuel system
  • Pre-heat system enables a cold start at -22 C 
  • Features two auxiliary power take-off points (PTO) in addition to the main PTO which can be loaded with 130 Nm continuously
  • Mounting works with an additional housing with a gear ratio that is driven directly by the camshaft
  • Includes sophisticated sensor system which can shut off engine in an emergency to avoid damage
  • Equipped with two valves per cylinder for high efficiency, mechanical robustness and functional simplicity
  • Bosch Off-Highway common rail system with 1,800 bar works with three injections per working cycle, providing durability, quiet combustion and excellent emission values
  • Features efficient fuel consumption rate of 205 g/kWh
  • Fuel savings potential is approximately 30% compared to EU Stage II engines
  • EGR mixing nozzle evenly distributes recirculated exhaust gas together with fresh combustion air to all four cylinders
  • Features fewer moving parts which leads to reduced internal friction for improved fuel efficiency
