As fuel economy, performance and emission should be greatly increased in development of the engine to meet recent stringent emission regulations, the design of the piston requires mostly fuel economy enhancement by reducing friction and lower inertia by reducing mass and thickness but also thermal durability for high power. The piston’s temperatures in various points were measured using ratio telemetry monitoring system. In this study, the piston temperatures were measured with and without oil jet which is nowadays adapted for recent high power engine and different oil jet targeting and according to engine coolant temperature, oil temperature and EMS parameters such as spark timing, air fuel ratio, TQ transient, to suggest fundamental data for developing engine.
