torque that the engine will produce. Also,

sometimes referred to as COMMAND

plate.

2. Peak Torque RPM (RPM) - Engine speed at

which peak torque is generated. This is

listed on the engine data plate.

3. Maximum HP RPM (RPM) - Engine speed

at which maximum power is developed. This

is listed with Advertised Horsepower on the

engine data plate.

4. Advertised Horsepower (HP) - Maximum

power that the engine will develop. This is

provided on the engine data plate with its

corresponding engine speed.

5. Command Range (RPM) - The engine’s

operating range from COMMAND TORQUE

or Peak Torque up to the engine’s governed

speed.

6. COMMAND Point - The point on the per-

formance curve where maximum horse-

power and optimum fuel economy come to-

gether. This is the point where Advertised

Horsepower occurs.

7. Full Load Governed Speed (RPM) - De-

fined as the upper end of the engine’s full

load operating range. This is listed on the
