First Electronic Single-Cylinder Diesels

Hatz presented at Bauma 2019 trade show the new E1 technology to equip single-cylinder engines with electronic controls. This new technology is intended for Hatz’ single-cylinder diesels of the B-series and D-series.

The first three Hatz engines equipped with E1 – the 1D90E, the 1B30E and the 1B50E – have been unveiled at the show in Munich, Germany.

Maximilian Eder, Hatz’ project manager E1, explained that the most important components of this technology are the engine control unit, sensors and fuel injector, with an electromagnetic valve specially developed by Hatz in cooperation with Bosch. He added that the control unit continuously measures the speed, oil pressure, oil and engine temperature, operating time or environmental data, such as air pressure or air temperature. Machine manufacturers and operators can retrieve engine-relevant data using the new Hatz diagnostic tool HDS² and via CAN J1939, for analysis or servicing purposes. 

The E1 technology features additional functions, as for example automatic start protection for preventing starter damages and idle connection control for automatic shut-down in case of too-long idle times.

A universal interface allows for a continuous data exchange with the control unit. The transfer of data in both directions enables engine data to be analysed and new data to be loaded. Various operating modes can be set, for example constant speed for certain applications, eco mode for emission-sensitive environments or an adjustment of the engine to different fuel alternatives. Furthermore, the interface of the E1 technology functions as the core component for the integration and networking of machines in digital applications and the Internet of Things in order to also integrate small devices and light equipment in the digital applications and processes of modern companies for the first time: a capability that Hatz has labelled ‘Connected Services’.
