Future engine technology capable of meeting the dramatic emissions reductions and fuel economy legislators are asking for will require much faster simulation techniques than are currently available.
WAVE-RT is the first real-time simulation software package which can eradicate many of the cumbersome techniques currently in use, producing precise results in real-time and at blistering speed.
Despite the high levels of sophistication reached in current combustion engine designs, demands to reduce regulated emissions and fuel consumption and hence CO2 will certainly lead to the need for even more technically advanced solutions in the future. Far from being at the limits of what is possible today, new control strategies and engine architectures are already evolving that, in as little as five years, could transform the low emissions capabilities of both gasoline and diesel engines.
The talent and knowledge to do this is not in short supply. But time is; time to run the kind of simulations needed to provide these solutions and time to get answers needed for decision making early in the life of a new engine project. An additional problem is the limitation imposed by current simulation tools, particularly when it comes to hardware-in-the-loop testing (HiL) when it comes time to validate strategies for controlling these technologically-advanced engines.
Historically look-up maps have been used to model the engine in HiL tests, but these are very simplistic and do not properly represent the engine in situations such as transients. In recent years, maps have been replaced by mean-value engine models (MVEMs - also known as lumped parameter models). Until now, MVEMs have been generally satisfactory for existing engine technologies. However these also do not respond well to rapid transient events as they are unable to capture wave dynamics; they also suffer from....
