Compact module for the interactive engine management system of commercial vehicles

Kohler-Lombardini optimizes the control of its diesel engines with the CANarmatur from ehb electronics gmbh.

In use where performance counts: Kohler-Lombardini is one of the global technology leaders in engine production for commercial vehicles. The company optimizes the control of its diesel engines with the help of CANarmatur from ehb electronics in Hanover. The result of this combination of Italian driving pleasure and German engineering competence is a high torque, long maintenance intervals and excellent exhaust emission values that meet all worldwide exhaust emission standards; i.e. Stage V for Europe, Tier 4 Final for the USA and for the rapidly expanding Asian market.

"Tommaso Maria Vezzosi, Jr. Communication Specialist at Lombardini Srl, says: "In addition to the technological excellence of our products, the compactness of all components is decisive in our production processes in order to manufacture our powerful motors as small and light as possible. ehb electronics specialists work closely with us to offer our customers a compact control module for installation on the motor as well as on the machine".

Power control via CANbus ensures economical fuel consumption

Whether in an excavator, in a 4WD tractor or as a drive for a compaction roller - the KDI 1903 TCR, 2504 TCR and 3404 TCR engines have a lot to offer. With a maximum torque of 640 Nm at 1400 rpm, the KDI 3404 TCR is the most powerful engine in these three product series. All engine variants feature a CANbus SAE J1939. This in turn forms the interface for the individual configuration of all settings for the different areas of application of the engines. The respective engine management system (MMS) of the individual engines provides information on operating values on the CANbus - for example, oil pressure, temperature, target and actual speed, operating hours and much more.
Since Kohler-Lombardini works with an MMS according to the SAE J1939 protocol, the ehb CANarmatur can receive and decode all values provided by the MMS and display them on the integrated and backlit display with automatic contrast adjustment. For very few applications, all available data is actually relevant, so that it is possible to determine which key figures are to be used depending on the type and use of the vehicle. For example, the parameters for the advanced combustion system and the diesel oxidation catalyst (DOC) integrated into the exhaust system are configurable. All critical engine parameters are visible and controllable at a glance and the resulting fuel consumption is up to 15% lower than for a similarly powerful engine without communication capability with the MMS.

Well positioned: Low-emission high-performance diesel engines with optimized maintenance cycles

According to the VDMA Construction Machinery and Building Material Industries Association, the global turnover of the construction machinery industry in 2017 was approx. 117 billion euros, with positive prospects for the business climate of European construction machinery manufacturers. Even if these figures do not yet take into account the latest developments in the tense trade relations with the USA, the number of infrastructure projects planned and approved by the European Commission is enormous and suggests a continued positive development in order intake and sales in all sub-sectors of building construction, earthworks and road construction. In addition to the energy and pollutant efficiency of the high-performance engines, another factor is decisive for the purchase decision: continuous availability even under the most demanding climatic conditions.

Bernd Reinmold, Managing Director of ehb electronics, explains: "Kohler-Lombardini's KDI engines are known for their high product quality and the plant in Italy offers its customers excellent service with short delivery times. The machine operators can communicate directly with the engine management system via the ehb CANarmatur and it is conceivable in the future to transmit the data to the fleet management system almost in real time and jointly expand the area of predictive maintenance. The technologies are already available and the added value would be enormous".
