The piston moves up and compresses the trapped air fuel mixture that was brought in by the intake stroke. The amount that the mixture is compressed is determined by the compression ratio of the engine. The compression ratio on the average engine is in the range of 8:1 to 10:1. This me...

These gasses well only in engines like free piston engines that don’t use a spinning mechanical output shaft and can be completely sealed. The Whispergen Solution Some recent designers of Stirling engines, notably Don Clucas the designer of the Whispergen Stirling engine from New Zealand, have ...
As the gas expands, it pushes the work piston to the right, which drives the flywheel and whatever the engine is powering. In this part of the cycle, the engine converts heat energy into mechanical energy (and does work). Transfer and cooling: The displacer piston moves to the left and...

How an engine works Almost all cars currently use a four-stroke combustion cycle to convert gasoline into motion. That is to say that the Intake stroke, Compression stroke, Power stroke and Exhaust stroke are one engine cycle. When the fourth stroke is completed, the cycle begins again. The...
So if we press down with a small force on a small area, at the narrow end of the tube on the left, there must be a large force acting upward on the larger area piston on the right to keep the pressure equal. That's how the force becomes magnified....
The piston is connected to the crankshaft by a connecting rod. As the crankshaft revolves, it has the effect of "resetting the cannon." Here's what happens as the engine goes through its cycle: The piston starts at the top, the intake valve opens, and the piston moves down to let the...
The radial engine has the same sort of pistons, valves and spark plugs that any four-stroke engine has. The big difference is in the crankshaft. Instead of the long shaft that's used in a multi-cylinder car engine, there is a single hub -- all of the piston's connecting rods connect...
That said, the engine did in fact propel itself during short portions of my testing, even if it isn't completely obvious in this test.Step 2: Theory of Operation: How a Jet Engine Works Before one being build a jet engine, it's important to first know how a jet engine works. ...
