Measurement of Wrist Pin Rotation relative to piston is achieved using IRT's proprietary sensors and wireless telemetry technology. Our system not only measures the angular value, but also the angular velocity, direction, and number of rotations over the course of a running cycle. These values provide insight to lubrication and bearing design. By optimizing these factors, engineers can reduce losses and improve overall engine performance and efficiency. Leading engine manufacturers have relied for years on data from our Wrist Pin Rotation Sensor to guide their design optimization. When combined with our proprietary Piston Friction Measurement System, a comprehensive understanding of piston behavior can be achieved. Contact us for a detailed review of your requirements.
