The SGS Thompson microprocessor was developed for Bosch as an automotive engine controller. They are used in many leading European cars. DieselGas chose the ST10 269 microprocessor for DieselGas engine control applications because of its suitability and flexability. The embedded software is written in C language and runs to more than 15,000 lines.

The algorithms use 3 servos, up to eight tables and more than 400 settings. The software is written to allow for expansion and modification.

The ST10 269 microprocessor allows the software to be locked giving the ultimate security for this intellectual property.

The engine management system includes the DGTech technician interface programme that allows automatic fault detection reducing the possibility of engine damage. Self diagnostics and automatic fault logging allows for the identification of any fault by automatically recording the engine operating parameters at the time a fault occurs. The fault log records the 20 seconds of engine operation prior to a fault being logged. A graphing programme allows detailed analysis of all parameters to identify the cause of a fault. Diagnostic, statistical and substitution logs can be recorded manually and analysed. The logs can be easily sent electronically to the factory for analysis and rapid diagnosis of problems or review of the engine operating history.

Dual fuel & dedicated

The DieselGas controller was initially developed for dual fuel engine control and is now available for dedicated gas engine control. The next development is to use the ST10 for genset applications.

Development for other applications

The ST10 is also suitable for diesel engine control and can be used to control an electronic governor on diesel or dual fuel engines.

Applications

DieselGas controller are available as part of dual fuel or dedicated gas kits or alone for other applications.
