Measure in Joules
The capacity to do work
"Rated Power" is the brake power developed by an engine in good condition under
standard conditions and at a stated RPM
full throttle
standard conditions and full throttle height
full throttle and at service ceiling
Power is
the rate of doing work
equal to Force x Distance
the capacity to do work
a turning or twisting force
Which of these conditions will produce the most efficient engine performance? Select all that apply
Mixture properly leaned

Mechanical Efficiency involves the relationship between power input and power output. It can be calculated by;
brake power divided by indicated power
brake power divided by fuel consumption
volume of the charge divided by piston displacement
fuel flow divided by brake power
Volumetric efficiency can be calculated by
brake power divided by indicated power
brake power divided by fuel consumption
volume of the charge divided by piston displacement
fuel flow divided by brake power
The Thermal efficiency of an engine is the
brake power divided by indicated power
brake power divided by fuel consumption
volume of the charge divided by piston displacement
fuel flow divided by piston displacement
