Abstract

When an I. C. engine is designed and manufactured, then it is tested in the laboratory. The purposes of testing include: to determine the information which cannot be obtained by calculation; to confirm the data used in design, the validity of which may be doubtful; and to satisfy the customer regarding the performance of the engine. By performance, we mean the operation of all variables relating to the working of the engine. These variables are power, fuel consumption, etc. An internal combustion engine is put to the thermodynamic tests, so as to determine the following quantities: indicated mean effective pressure, indicated power, speed of the engine, brake torque, brake power, mechanical losses, mechanical efficiency, fuel consumption, thermal efficiency, air consumption, volumetric efficiency, various temperatures, and heat balance sheet. It may be noted that these quantities (analytically determined) are measured after the engine has reached the steady conditions.
