LONDON - Ricardo Consulting Engineers has teamed up with DaimlerChrysler and Kistler Instrumente, the Swiss sensor supplier, in a project to develop advanced engine management technology that will lower fuel consumption and improve vehicle performance.
The objective of the project is to assimilate cylinder-pressure eng-ine management system technology (CPEMS) on a vehicle.
The underlying goal is to obtain substantial improvements in the cost, efficiency and reliability of sophisticated `model-based' engine management control systems.
Ricardo says the impact on the engine will be reduced emissions and lower fuel consumption as well as improved vehicle performance, driveability and refinement - resulting in more comfort for the driver and passengers.
The AENEAS project - Application and Evaluation of a Novel Engine management system - has also won financial support from the European Commission as an Innovation Program.
The project is expected to lead to:
Better controlled combustion giving lower emissions and smoother running
Improved catalyst warm-up because of better control over exhaust conditions
Improved sensing leading to a reduced number of sensors which work faster
Reduced number of engine maps
Improved adaptive capabilities
Increased suitability for model-based control systems
Improved on-board diagnostics
Despite the potential benefits of model-based control and diagnostic applications, their use within the automotive industry has been hindered mainly by the lack of inexpensive sensing devices that can closely monitor the engine's performance.
In particular, the measurement of cylinder pressure, which would give valuable information on the engine's performance, has suffered because of the expense.
