What is the operation of a piston?

It transfers force from the expanding gas in the cylinder to the crankshaft via a piston rod.


Where is piston rings located in engine?

The piston rings are fitted round the piston to make a better gas-tight fit in the cylinder.


What happens to the density of gas particles in a cylinder as the piston is raised?

As the piston is raised in a cylinder with gas particles, the volume available for the gas particles to occupy increases. This results in the gas particles spreading out and the density of the gas decreasing.


Why piston rings are too loos on piston?

gas pressure has to get round the back of the ring to force it against the cylinder wall


How much clearance is allowed from the piston to the cylinder wall on a 2000 YZ 125?

Well...... you need A LITTLE bit of clearance for the gas mixture to lubricate the piston and cylinder. Plus your piston expands when it gets hot.


How do cars use gas?

Simple explanation : the gas in forced into the cylinder, then the piston compresses it, then the spark plug makes it explode, which forces the piston back down, turning the crankshaft, forcing another piston into compressing more gas. rinse and repeat.


Is piston cylinder process is constant pressure process or constan volume process?

A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.


So if a gas tank and cylinders aren't the same what do the cylinders do?

No a gas tank is where you store the fuel a cylinder is the housing for the piston in the engine.


What is a stirling engine?

The Stirling engine was invented by Reverend Dr. Robert Stirling and patented by him in 1816.It is an engine that gets it's power from the movement of heat energy from a hot place to a cold place. It consists of two cylinders, the first one is called the displacement cylinder and the second one is the power cylinder.The displacement cylinder has two sections, a hot section and a cold section, the piston in the displacement cylinder is a loose fit so that air or gas can pass by when it is moving, the purpose of this piston is to move the air or gas from the hot section to the cold section and back to the hot section hence "displacing it".Second is the power cylinder containing a double acting piston that is connected to a crankshaft fitted with a fly wheel.When the displacing piston moves to the cold part of the cylinder, the largest volume of air or gas is in the hot part of the displacement cylinder, where it will heat up and expand to a higher volume and push the power piston outwards, when the displacement piston moves to the hot side of the cylinder the air or gas moves over to the cold side of the cylinder, where it will cool down and shrink to a smaller volume and form a vacuum that sucks the power piston in the opposite direction.


What is difference between reciprocating compressor and a rotary compressor?

A rotary compressor has screws or gears that compress a gas. A reciprocating compressor has a piston in a cylinder compressing the gas.


What happens when a piston moves down on the gas?

When a piston moves down in a gas-filled cylinder, the volume of the gas increases, leading to a decrease in pressure according to Boyle's Law, which states that pressure and volume are inversely related for a given amount of gas at constant temperature. If the temperature remains constant, the gas molecules spread out as the piston moves down, resulting in lower density. If the gas can absorb heat, it may also expand and do work on the piston, potentially increasing the temperature depending on the conditions.


What would cause gas in the oil?

Could be a serious problem. Most likely a bad piston ring allowing gas to slip by the piston and cylinder wall, and mixing with the oil in the crankcase. --- It would depend on the car. It could also be sticking injectors.
