The industry's leading real-time engine simulation tool
WAVE-RT is the industry's leading real-time engine simulation tool providing faster-than-real-time plant models which don’t require any reduction in model complexity or fidelity.
How it works
WAVE-RT converts a donor WAVE model into a real-time engine model that accurately predicts crank-angle resolved engine behaviour throughout the air path and within individual cylinders. It does this through a combination of mathematical modelling based upon the quasi-propagatory model (QPM) and highly optimised code that results in a minimal reduction in model accuracy. It represents a suitable compromise between the accuracy of 1D computational fluid dynamics (CFD) models (such as WAVE) and lumped parameter models. Therefore, it is a significant advancement over traditional map-based approaches.
What is it typically used for?
Developed to validate engine management systems, WAVE-RT can run on software-in-the-loop (SiL) and hardware-in-the-loop (HiL) environments, rapid prototype control units (rCube2) and mini computers equipped with ARM processors. It facilitates the design of advanced performance, emission and carbon dioxide (CO2) control strategies, and on-board diagnostic (OBD) algorithms.
In addition, WAVE-RT can be used for virtual indicating, which provides access to states not easily measured, such as in-cylinder temperature and residual mass fraction augmenting experimental measurements.
