All right, I had recently a surge of inspiration to create a very awesome contraption, however, one of the most crucial informations in order to start out the design of this contraption is this car cylinder-like mechanism that it uses, and I have no idea how car cylinders work, and by that I mean the technical aspects, such as how would I calculate how much force is exerted by each explosion of fuel? What information do I need in order to make proper calculations? How do I calculate the perfect mix of fuel, compression and air for this mechanism? How quickly would it burn fuel? By the way, the fuel I'm planning to use is either petrol or diesel due to the fact that it's easy to acquire and the material quite probably aluminium. There's so much to this idea that it's incredible! I really badly need some help!
