"We've been working with ANSYS technology throughout this engine project and know that its software delivers fast and accurate results," said Sylvain Tremblay, president of SpeedSource. "We received one of the first production-block test engines straight from Mazda's production plant a bit later than originally expected, so we knew that we had to make strategic adjustments to the development process to compensate. With ANSYS, we were able to decrease the total solve time by around two-thirds, which was a huge time savings, and were completely confident that we had arrived at the optimal engine design."

ANSYS simulation software was instrumental in the design and validation of such SKYACTIV-D engine components and subassemblies as the racing piston geometry and bowl volumes. Specifically, SpeedSource used ANSYS� Fluent to model the in-cylinder combustion process for a full engine cycle and the results of this simulation, such as cylinder pressure and temperature. These results were then used to guide the design on other critical engine components such as connecting rods, pistons, and crankshaft. Fluent was also used to accurately model fuel injection, which is critical to engine performance and efficiency.
