Some years ago I developed a theory relating to measuring the efficiency of balanced systems or nearly balanced systems (according to the laws of physics ).
It was not until later, I realized that the combustion engine of a motor car was in itself a balanced system. Or rather the individual pistons within cylinders were systems within the overall system of the engine! (They could be considered individual motors making up a part of the total motor)
Anyway getting back to the theory - This required the monitoring of the system over a time frame of five timing points and at the end of that time to come to a logical conclusion as to whether the system was operating as efficiently as it could be or if there should be a small adjustment made!
This theory could then be applied to each cylinder of a combustion engine. There would be one timing point at top dead centre, a second at the bottom of the downstroke and three others in between.
The monitoring of the system would be via the compression ratio at each timing point per cylinder. Those five readings could be linked to get an overall picture of the performance of each cylinder.
ie.
1 - 2
1 - 3
1 - 4
1 - 5
2 - 3
2 - 4
2 - 5
3 - 4
3 - 5
4 - 5
These figures can be fed into a computer for analysis of exactly how much fuel that particular cylinder required injecting.
I am convinced this theory would work and would result in -

1. Greater fuel economy.

2. Greater horsepower for size of motor.

3. Greater Torque.

4. Smoother throttle for all loads.

5. Less maintenance costs.

6. Less emissions.

7. Cooler running.

I also am convinced that much of the present gadgetry on modern engines would not be required and would remain obsolete. With the cost of fuel rising exponentially the further we get into this Century, I believe it is imperative that we run smaller cars with more efficient engines.

In creating this article I wish it to be known that I am a layperson with very limited access to working on motor engines. All of my theories have been derived from logic! Excuse the pretty rough explanation involved!

With Kind Regards,

I have some quieries with this system
1 how would you monitor it whilts driving
2 if you could monitor it what sort of system would you use to vary the indiviual injectors
3 as far as less matinance costs i could only see it going up if you need a sie

Thanks for your interset Wayne. I did not mean for it to sound so complicated - it isn't really.

1. The system would utilise EFI and as such the ECU would do all the monitoring.

2. For the complete upstroke, the performance of the piston is monitore
