The piston moves down the cylinder
WebbThe piston pushes upward compressing the fuel and air into a much smaller space in the cylinder head, where it is then ignited by the spark plug. The resulting explosion forces … WebbThis is called "blow down". Depending on the cylinder pressure and how quickly the valve opens, a loud or sonic pulse can be generated. That is where the exhaust noise comes from, and why engines make more noise at full power than at idle. The piston then moves back to TDC up the cylinder, forcing all the remaining burnt air/fuel (exhaust) out.

In order to drive an alternator 11, Fig. 6, at a constant WebbAll functions are controlled solely by the piston covering and uncovering the ports as it moves up and down in the cylinder. In the 1970s, Yamaha worked out some basic principles for this system. They found that, in general, widening an exhaust port increases the power by the same amount as raising the port, but the power band does not narrow …

If the piston is at an angle, as it moves it makes contact with various places, and this can cause engine damage. The piston ring supports the piston so the piston can travel smoothly up and down. Types of Piston Ring fly by securityCommonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.
