We think, design and realize electronic systems able to totally respond to customer’s specifications. From prototyping to mass production. Our experience in developing embedded technology, especially in control electronics, hardware development software, microcontrollers and power electronics makes us able to offer innovative high technology solutions and also a broad range of services from PCB design to product re- engineerization. During these past years we pointed a lot on innovation acquiring a highly growing potential ready to be adequate to future change of the market
Engine management systems
CMD is specialised in developing electronics and special software for engine. Today we have the possibility to cover each phase to project engine management systems for each kind of engine (Diesel, gasoline, LPG).
WE successfully developed and put into mass production an Engine Control Unit for FNM common rail diesel engine based on FIAT engine 1,9JTD and 2,4 JTD. The ECU uses all the characteristics of the injection system to electronically control the fuel quantity, injection advance and fuel pressure. The ECU is also equipped with an autodiagnosis system able to recognize sensors and actuators failures. For each problem detected a recovery algorithm is triggered. The diagnosis communication was developed according to KWP2000 protocol.
In 2008 we developed an auto motive ECU for diesel engine. The different environment forces us to use adequated control algorithm specifically for emission controls thanks to EGR valve handling. The car had successfully complied with EURO 4 specifications (ECE 15 -cat. N1 -class III). Actually, the ECU is able to perform 3 injections by cycle. It is also possible to control both solenoid or piezo injectors.
CMD is developing two aeronautical engines: the GF56 (2 stroke diesel common rail engine) and the ULM220 (4 stroke gasoline engine). On each cases, CMD were chosen to develop the engine management systems.The entry of CMD on aeronautical market is a huge growing opportunity. Using aeronautical rules and specifical standards allows the creation of a design assurance system to control the projects.
To verify the status of an ECU it is necessary to use a diagnosis tool. Our EDR (Ecu Data Reader) is the tester to use with our ECU products and for FNM marine engines. Thanks to a powerful graphical interface it is possible to easily troubleshoot an engine. The tool runs on PC or PDA tank to a USB to OBD interface which simply plugs in the OBD connector of the engine. The EDR allows to read engine parameters (RPM, throttle position, rail pressure, etc…) and to log them for further analysis.
The calibration is a very delicate phase of engine development and needs special tools and methodology to create a robust product and improve the efficiency of experimentation.
CMD’S know-how allows to get a complete vision of engine’s behaviour and directly found the best compromise solution.
During last years, CMD, thank to collaboration with large research centres used methods and tools advanced to optimise experimental activity reducing both costs and time without penalizing results quality.
Calibration of control parameters and diagnosis algorithm present inside the ECU are reprogrammable in real-time thanks to the CID software developed by CMD.
CMD Crater’s is a diagnosis tester that allows to send to a control centre all the working data of the embedded systems of a vehicle. Particularly the ECU is accessible remotely.
Diagnosis tester doesn’t need installation of costly sensors but simply uses all the autodiagnosis features available on-board. It does so thanks to the use of appropriate communication protocols
CMD is also able to design and build wiring looms for engine. Thanks to our experience we can offer the best suiting solution for all wiring requests – engine, data acquisition, instruments, etc…
We can assure the complete development of a wiring solution. From the feasibility study to the virtual and real assembly.
Our experience allows us to offer:
- Analyze of current and voltage loads to appropriately choose cables dimension and quality. Selection of all the components (fuses, connectors…) adapted for the type of vehicle.
- Knowledge of computer aided design tools (CAD, CATIA, Unigraphics, Logical cable) to design, analyze and generate all the documentation necessary to build the wiring solution..
- Integration of electric and mechanical development in 3D.
- Handling of the project data and files: flowcharts, blueprints, schematics.
