Hardening the Concept: day one

2012-08-11T09:26:00.000-07:00

Okay, now that I have the basic theory worked out, I have to do about a thousand concept sketches, and a lot of research.

I will start by designing the cylinders/pistons with a diameter of 3cm (just like in the concept explanation) and an 8cm stroke. then I will design the rest of the engine around those. and somewhere along the way (probably soon) I am going to do the math to work out the realistic fuel required for the strokes of the pistons.

If any of you understand the rough theory and have anything you want to say, feel free to leave a comment or email me at lcdx5000@gmail.com

Okay I have an interesting theory about internal combustion engines.
The thought basically is that by reducing the size of pistons of an engine, and keeping the amount of fuel per piston the same you could downsize engines and produce the same essential power if not more.

I can't draw a diagram on this website so I'm going to explain the concept: so you have a piston that is 6 cm (centimeters) in diameter and 10 cm long giving it a volume of 282.6 cm3 (2.826 m3). Then you take the gas/air mixture that causes the famed combustion, with a fictional power of 5 newtons (a newton being the force required to lift 1 ounce straight into the are: oz/m).
note that the hard numbers are fictional for the purpose of exemplifying the theory and basic equation.
The equation is F(the original force of the explosion without being affected by the area available, measured in newtons) / V (the volume available to expand in the cylinder measured in meters) = P the amount of contained force that propels the cylinder.
F/A = P
For the purposes of this equation F=5 and A=1.2304.
5N/2.826m3 = 1.7693N.
From the equation we can say that our fictional average cylinder has an overall force of 1.7693 newtons which is used to propel the piston and by extension the crankshaft and so on to move the car. lets call this the minimal force required.
Now lets take our new theoretical cylinder which is half the diameter but everything else is the same. that is to say, 3 cm in diameter 10 cm in length (or height if that helps you picture it) and giving it a volume of 70.65 cm3 (.7065 m3). And the gas/air mixture with its fictional power of 5 newtons.
Now lets do the equation 5N/.7065m3 = 7.0771N.
That is 7.0771N of force propelling the piston. witch is 5.7519 times stronger than the minimal force required.
However this much extra force is unneeded and potentially even damaging the engine. so how do you reduce the amount of overall force? you lower the amount of starting force? and you do that by lowering the amount of fuel you start with.
So in summation thinner pistons mean more power produced by the same energy, and less energy required for the same force to be produced . less energy less fuel.
now you understand the theory, which requires more research and more realistic facts, but for now lets just say with the theory. wile i do more research you try to poke wholes on the physics, math, and the internal combustion engine assumptions. thank you all.
