It was truck engines that pioneered the transformation from mechanically controlled to the full authority electronic engines used throughout the large diesel engine industry today. The electronic control unit (ECU) fitted to the engines and often the gearbox transmissions has provided a wealth of diagnostics and also live data than could only previously been imagined. However this vast data source is often only available via specialist tools used by service agents. Most of the data available is filtered by the standard instrumentation fitted to the vehicles.
CANplus displays have many years of working directly with the top engine manufacturers and have a wealth of knowledge and insight into monitoring modern diesel engines. We can provide a generic off-the-shelf J1939 Engine Monitor (JEM) or customise our standard display to create a perfect match to your diagnostic and monitoring requirements. We can even supply the tools and support for your own engineering team to use the CANplus for research and development projects where your engineers can have full control over the functionality.
JEM supports 50 engine parameters and fault alarms in its standard form - a superset of all commonly required engine data - and will additionally calculate four further parameters including average fuel consumption. This information is displayed graphically using menu-driven split-screens, with a main display showing four gauges for key data, and other screens and information accessible by soft keys.
Users have a high degree of flexibility over display configuration, allowing application-specific gauges to be created easily. Configuration possibilities include the selection of gauges displayed on any screen, the use of analog or digital data display, graph trending, the units used, and selection of the language – with a choice of eight for the latter option.
Among JEM’s 19 engine data parameters are road speed, RPM, voltage, oil pressure and temperature, transmission oil pressure and temperature, coolant temperature and pressure, turbo pressure, inlet manifold and exhaust temperature, engine torque, and fuel level/pressure/rate.
JEM additionally offers the ability to manipulate data, and comes with four standard calculations that can be made available to end users: average fuel rate per hour, average fuel consumption per distance, trip fuel and trip hours.
Together with more than 30 fault alarms, this large J1939 feature set provides an adaptable platform that allows manufacturers to apply a single, standard product to entire range of diesel engine vehicles and products - ranging from the basic to the highly sophisticated.
The software is highly modular and designed for both modification and extension - and CANtronik will modify the displays on request. By using the built-in computing power and memory of CANplus displays, this programming flexibility extends to manipulating electronic control unit (ECU) and sensor data to create unique operator reports, views and calculations - giving OEMs a short-cut to differentiating their product offerings with high-value, user-focused controls and ergonomics.
CANtronik also offers support for Telematics. With our partner Webtrac we can also track your vehicle and send all of this data to a web-server so that fleet operators or individuals can remotely log any of the data and review historical data captured over weeks, months or years.
