Summary:

This work compares procedures specified on standard ISO-1585 applicable to piston engine bench dynamometer, with two quasi-static procedures. The first one is based on maintain constant the engine rotation and the load during 1 minute and then modified the work conditions. This procedure results in a step test when using a continuous data acquisition system. The other one is based on change the engine rotation and load continuously during the test, in a way that load and rotation stay ever on PID equilibrium. This allow, during one season, acquire hundred of engine operating condition points. The objective is to demonstrate that these tests procedures accomplish the Brazilian standard and they don't introduce news mistakes. The advantage of these procedures is to reduce the time required to execute engine test. Other advantage is allowing the process automation. Power curves are shown for a four cylinders in line, 1300 cm3, 16 valves engine measured following the three procedures. The results showed the equivalence between the static and quasi-static test procedures
