A piston moves down during the compustion stroke because of the energy produced by fuel compustion... but what makes it move up again during exhaust stroke then down during intake stroke then up in compression stroke?

1. the momentum created by rotating mass, ie: crankshaft, flywheel and harmonic balancer
2. When one piston is not on it's power stroke, at least one of the other 3, 5 or 7 pistons are.

Newton's law that an object in motion tends to remain in motion. The power stroke starts the flywheel turning. The kinetic energy will keep it moving through the exhaust stroke (exhaust valve open, little Resistance, putting the byproducts of the explosion out the tail pipe), the intake stroke pulling air fuel in, again with an intake valve open, the compression stroke which will have some residence as the fuel air compression, and again the power stroke that starts it all over again. As long as the power stroke will keep things moving for the next three cycles, it will continue to run.

As each cylinder fires, they do so in an order that will allow the other cylinders to constantly be providing power to the crankshaft, thus, the other cylinders firing are what move the piston during its compression and exhaust stroke

Spinning Mass of the flywheel "FLYING WEIGHT" inertia stored energy. Newton's law something in motion tends to stay in motion. The flywheel drags the piston(s) around the 540 degrees. Remember if there are more than one cyl four cyl engines fire every 180 degrees six cyl and V-8 have enen more power pulses. The more cyls the smoother the engine runs and better the exhaust tone.

The flywheel is what keeps the piston moving. The piston has to actually stop and reverse direction so it's momentum does not help, it actually hurts. The other cylinders do help but there are single cylinder engines in motorcycles etc. that rely solely on the flywheel.

The main reason the piston keeps moving is momentum there is usually a flywheel attached to the crankshaft. The more cylinders there are the lighter the flywheel can be.

1. Momentum for one thing. An object in motion remains in motion until acted upon by a force.
2. The remianing pistons firing and keeping the crankshaft in motion. All the pistons are connected to the crankshaft, so each piston in turn fires, and drives the crankshaft and all the pistons continue to move.

because you have no longer have been given a distributor to reference slack interior the chain with, you're caught with pulling a valve cover. Then placed a wrench on the crank, slowly turn the crank at the same time as gazing the valve practice for circulate. as quickly because it strikes, mark the crank with chalk and now bypass interior the alternative direction. How a techniques are you able to progression it in the previous you notice valve circulate lower back? this is the slack interior the chain, something in a techniques extra suitable than 8 stages is time to swap the timing chain and gears. stable luck

The balances and counter weights on the crankshaft work to balance the blast of the power stroke and evens out the initial explosion ,, thus carring the stroke more than the one turn ,,
