Tongues in engines manner of measurement of amount of mechanical horse.
Each engine owns invariable parameters about definite , like :
Sum of inertia mass, sum inertia springs, chains ,valves,etc.
Each model of engine has this parameters exactly SAME !!
And if for example, we want it without load for 4000 RPM ,at same time , we need exactly SAME horsepower.
It is principle my idea: Horse Power Meter.
Manner of measurement Horse Power:
Car is stop !!
We have running engine in idle RPM.
We need only same impulse classic RPM meter
Next we push and press i electronic meter switch "measurement"
Next we must push throttle in FULL .
Engine go to eg 5000 RPM.
Electronic measurement TIME with special SOFT , how long engine going measurement period 3000 rpm to 4000 rpm . This TIME are equivalent horsepower of engine.
Little power -long time , normal power - short time
Idea in diagram:
Next diagram electronic of Horsepower Meter, can made little 8 -bit processor eg. AT2051. Small individual Soft for each model of engine:
