Hatz B-series: Flexible solution for all areas The Hatz B-series scores high marks in mobile and stationary operations with compact installation dimensions and for all applications with a power requirement up to 8 kW due to its low weight. With its robustness and longevity, the series sets standards in the market. Regardless of whether on vibration plates or in the inhospitable environment of the Antarctic, the B-series has been tried and tested a hundred thousand times in harsh surroundings. Environmental aspects In our company protection of the environment is regarded as a key component of the company objectives. For example, the B-series engines are exclusively produced and marketed to the specification of the strict EPA Tier IV exhaust directive, even in countries where no limits are imposed on exhaust emission.

One power train – many variants Thanks to the intelligent design of the engines, not only is it possible to offer various displacements based on the same power train but we have also succeeded in bringing the entire series as vertical engines (engine with vertical crankshaft and horizontal cylinder) with the same basic power train onto the market. For the customer, this provides many options for making the best possible use of the existing space on a machine, either heightoptimized with the vertical engine, or with the conventional engine with optimum base area.

Optional noise package Depending on the engine type the current low noise level can be significantly reduced further, even by 2 to 4 dB(A), by a noise package, decreased power and speed. This is possible thanks to optimizations in the area of intake and exhaust components.

SCS (Single Cam System) One of the numerous innovations of the B-series is the single cam system, where the injection pump and the two valves are operated by just one cam and rocker arm. This design detail, for which Hatz has applied for a patent, substantially determines the very short overall length of the engine. In addition, the camshaft is driven via a gear wheel which is, at the same time, a component and drive of the oil pump.

1B20V / 1B30V / 1B40V / 1B50V As the only engine manufacturer worldwide, Hatz offers a diesel series with vertical crankshaft. For many applications, such as the prime example of the lawnmower, this design provides major advantages and significantly simplifies installation.

Flexibility through additional equipment The B-series can be fully customized to the needs of the customer with an almost endless list of accessory parts. Among other things, there are six different output shafts for each type, an electric start with 12 or 24 V as well as various options for fuel tanks and filters, to name but the most important ones.
