Irrespective of whether the required standards are met within the engine itself and/or with different exhaust aftertreatment concepts, we can no longer do without state-of-the-art control units that operate discretely in the background. The number of electronically regulated components on combustion engines will continue to increase in the future. This in turn increases the integration effort, while also making extensive test series necessary, increases the likelihood of responsibility conflicts("finger-pointing') and lowers the level of reliability. The use of platform solutions however does help to re-duce system complexity, while simultaneously spreading the testing outlay between the OEMs own R&D and development partners. The new HEINZMANN control unit model series represents a platform solution which enables those customers who wish to develop their own software to relieve themselves of the need to deploy scarce and valuable R&D resources for routine tasks, and to concentrate on the expansion of core competencies, unique selling points and complex control algorithms. Customers that do not have their own software department benefit from the use of HEINZMANN-developed function libraries that have proven their value time and time again in the field. An open software platform based on RTOS has almost no restrictions in terms of the development tools to be used. Established development tools are supported such as,e.g. Matlab/Simulink, CoDeSys, and, naturally, the conventional method of programming using Embedded C. Thanks to the modular software architecture, the integration of customer-specific solutions and protected algorithms is extremely easy. One of the key elements in complying with state-of-the-art exhaust standards in diesel engines is the CR injection technology including the control system. More and more complex actuation algorithms, combined with calculation-intensive methods for the compensation of injection-system component tolerances and long-term drift, require powerful hardware and optimized soft-ware operating-times, that when used together enable not only emissions to be reduced, but also compensates for the wear suffered by the injection system components. Special attention was paid to both the simple connection ability to the various exhaust after treatment components, as well as the actuation of VVT, EGR and WG. Dual fuel applications are also gaining more and more in significance. To this end the new HEINZMANN control system provides a basis both for actuation on the diesel side as well as comprehensive range of monitoring and control of exhaust-gas components. Here too our platform solution provides ideal integration of components with each other while the final result achieves maximum efficiency with regard to the diesel-to-gas conversion rates and reliable operation. Nowadays, next to pure functionality, it is the ease of configuration and user friendliness that are of major significance. Remote support options and fast link-up to superordinate systems is another important factor, which enhances the appeal of the customer end product, while opening up brand new options for developing individual service solutions and products.
