State-of-the-art Rig Testing equipment is deployed for validating the prototype in a near virtual engine condition. For example, a Piston can be pulsated for over 2 million cycles to confirm the design strength under varying gas force loads. For an ultra light gasoline piston, the same test can be done to check fatigue failures both under gas forces and inertia forces.
Apart from these, there are custom made rigs for testing new materials and surface coatings in Piston Rings as well.
A separate engine testing facility has been established to validate the prototypes in line with the test cycles specified by the OEM. SPR is proud to have partnered with many leading OEMs for sharing the responsibility of testing for many new programs. The various tests being conducted are:
The concept model is refined through Finite Element Analysis (FEA) by applying the various load conditions foreseen in the engine. FEA analysis of a piston will yield following:
