dSPACE has added new functions for diesel engine simulation to its Automotive Simulation Models (ASM). From the start of 2007, the ASM Diesel Engine Simulation Package has an exhaust gas aftertreatment system consisting of physical models for a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The model supports the development and testing of modern engine management systems with pollutant reduction that fulfi ls the legal requirements.

The functionality is rounded off by a new standard parameter set for a 40-tonne truck equipped with a 6-cylinder, 12-litre diesel engine. Thus, users can start work with the model even if they have no parameter data of their own.

Like other ASM functionalities, this new one is visible to users right down to Simulink block level. This makes the model ideal for making customer-specific modifications and extensions. The model can be run in real time on a dSPACE Simulator for testing electronic control units by hardware-in-the-loop (HIL) simulation. Used in function development, the model supports Simulink offl ine simulation.

dSPACE offers additional models for the ASM – Diesel Engine Simulation Package, such as a vehicle dynamics model for constructing a virtual vehicle, and a physical turbocharger model.
