Description

Hatz H-series: innovation meets reliability.

The 4H50TIC Hatz Diesel Engine is the pinnacle of this new breed of heavy duty Diesel Engines from the German Manufacturer, Motorenfabrik Hatz GmbH & Co.

A groundbreaking downsizing approach was adopted in the development of the Hatz H-series. The outcome are extremely compact, turbocharged engines that reach a maximum output of 64 kilowatts, setting benchmarks in their performance classes.

• Power from 28.7 to 55.4 kW
• Max. torque 244 Nm
• Bosch OHW common rail-system with 1800 bar
• Exhaust-gas turbocharger with intercooler
• EPA Tier 4 final certified
• Available as an Open Power Unit

Downsizing Approach

The key objectives were the reduction of size and weight with simultaneously higher power and good exhaust gas values. The results are very convincing: Weight and consumption values are lower than those of any other engine in this class. This could be achieved, among other factors, thanks to the iHACS technology (intelligent Hatz Advanced Combustion Strategy) with its sophisticated combustion chamber geometry, Bosch injection technology, minimised friction and a maximum charge air pressure of 1.7 bar.

Modern Engine Family.

Compact, light, economical, robust and environmentally friendly: The common-rail diesel engines of the Hatz H-series provide everything expected from powerful and modern industrial engines. They impress through their quiet running, dynamics and maintenance friendliness. Their constantly low fuel consumption over a wide load range sets the benchmark.

High Maintenance Friendliness

A maintenance interval of 500 hours means the engine scores top points with regard to customer friendliness and reliability. The extended intervals are due to hydraulic valve adjustment and large-sized filters. Additionally, the engine has a shut-off sensor system that switches off the engine in an emergency to avoid major damage.

Optimum Combustion Strategy For Every Need

The exhaust gas return system was further developed by Hatz engineers to have a positive effect on the exhaust gas values. A pre-cooling unit for the exhaust gas return (EGR) significantly reduces the exhaust gas temperature before the EGR valve, protecting it against thermal damage and sooting. An optimized EGR-mixing-nozzle is also used. It uniformly distributes the recirculated exhaust gases together with the fresh combustion air to all four cylinders. Together with the common rail system, the result is an outstanding exhaust gas quality which ensures that the TIC models are only equipped with a diesel oxidation catalytic converter (DOC) and there is no need for an additional particle filter. Furthermore the engines significantly undercut the emission limits of EPA Tier 4 Final and EU Stage IIIB.
