Performance test

Performance testing is conducting a test of performance by actually running an engine under various running conditions to learn engine performance.
Normally, the engine is run with a fixed load and power meter load, rotational speed, fuel consumption, lubricant temperature, lubricant pressure, coolant inlet and outlet temperature, intake pressure, etc. are measured; and, after these measurements are complete, the amount of lubricant consumed is measured.
Output, torque, fuel consumption rate, and net thermal efficiency, etc. are calculated from these measured values and shown on a line diagram. This line diagram is referred to as an engine performance curve.
