摘要：
This article describes a process and results from measurements of mechanical friction in internal combustion engine as affected by oil temperature. Oil and cooling water temperatures were controlled in a wide range. Spark plug adaptor with integrated pressure transducer was used for IMEP determination. Obtained results were compared with engine motoring method. DC dynamometer was used for breaking and motoring the engine. Insufficient accuracy of torque measurement with reversible weight mechanism led to installation of measurement reaction force of dynamometer stator by strain gauge. This in-house designed arrangement is also described here.
