Dynamometer Project
This project will involve mechanical, electrical and electronic engineering.
The dynamometer will enable us to compare the power output of different engines, or different settings and tuning arrangements of a particular engine.
The principal of calculating the power output is very simple.
We will load the engine using it as a generator producing DC current to light up
a flood lamp. By measuring voltage and current we can calculate the power output
which we can use for comparison purposes. If we then measure the efficiency of
the dynamo we can calculate the true power of the engine.
