The German based company Motorenfabrik Hatz will have a variety of new products at this year's CONEXPO in Las Vegas. Most important will be the American introduction of the 4H50TIC water-cooled, multi-cylinder turbo engine, which in particular is characterized by its compact design. Developed with a consistent downsizing approach, the engine is especially tailored to customers in the U.S. and the EU.

Moreover, the business field 'Hatz Systems', which develops and sells entire systems based on the Hatz diesel engines, will showcase a combination system, consisting of a climate compressor and alternator, as well as the PM generator IPP (intelligent power pack).

All exhibits will be shown on a newly designed booth in South Hall 4 booth No. 83740.

American premiere: Hatz 4H50TIC

Since January 2014, the engine lineup of Motorenfabrik Hatz has been extended with a new member: the 4H50TIC (TIC: turbo intercooler). Sales of the 2-liter diesel engine, which is equipped with a Bosch common rail system, started in January 2014. Like all Hatz engines, this engine also brings a number of technical innovations with it which make it the most compact in its class with the best power density compared to its competitors.

With 1,952 cc, the engine has a maximum power of 75 hp (55 kW) and a maximum torque of 240 Nm, which is already available from as low as 1,600 rpm. Including starter and alternator, the engine weighs just 381 lbs. (173 kg) and thus saves 198 lbs. (90 kg) compared to its next competitor. Therefore the engine has by far the lowest power to weight ratio in the power class up to 56 kW.

Due to the new combustion process iHACS (intelligent Hatz Advanced Combustion Strategy) and an optimized combustion chamber geometry, combined with the sophisticated technology of the Bosch common rail system, which operates with injection pressures up to 1,800 bar, the particulate emissions are considerably reduced. Therefore it is possible to achieve the exhaust emissions standards EU 97/68 Stage IIIB and EPA Tier 4 final without the use of a diesel particulate filter.

Apart from the technical data the engine also scores high marks with low cost of ownership; firstly because of a low fuel consumption of 205 g/kWh (best point), and secondly because of a long service interval of 500 hours.

1D81C Aircon APU

The 1D81C Aircon APU combines an air conditioning compressor with a generator and is driven by an air-cooled diesel engine. Application areas for the Aircon APU are primarily construction machines, which are driven by a large engine. On average, construction machinery is used between 30 and 50% of the time in daily use, and the large engines run at idle speed for the other times. In addition to an average fuel consumption of 16 to 20 l/h, this also shortens the time between maintenance intervals.

The Aircon APU supplies cooling air to the cab via the compressor and simultaneously charges the batteries of the machine. Depending on the requirements, the system can be operated with various Hatz engines. The Aircon APU consumes approximately 2.1 l/h. In best case, the system saves about 16,000 liters of fuel a year, so that it will pay for itself after 12 to 15 months. In addition, the Aircon APU gives security against upcoming non-idling laws in the U.S. that prevent the use of the main engine for air conditioning during idle time. Because of its compact size, the 1D81C Aircon APU can be easily integrated into existing applications.
