Can a foreign object work its way into the piston chamber from the valve head of a car?

Yes. That is why it is important to use an air filter.

Why is spark plug smashed?
Usually it's because SOMETHING found it's way into the combustion chamber and was bounced around for a while by the piston. Occasionally when that happens the foreign object will embed itself into the piston or find it's way out the exhaust valve. Whatever it is, it's not good.
What do piston do in a car?
A piston draws air into the cylinder through an intake port. The intake valve closes and the air/fuel mixture compresses as the piston moves back up. Once the mixture is fully compressed, it is ignited and explodes forcing the piston down (this is known as the power stroke). An exhaust valve opens and the burned gases are expelled out of the cylinder as the piston moves back up to complete its cycle. This is different from a heart valve. A heart valve would be similar to a bicycle tire pump though. As the piston draws air into the air chamber,the valve opens to allow the air to fill the chamber. the piston then, changes direction and pushes that valve closed and opens another valve to allow the air to be pushed out the air line. The difference is in the valves. a bicycle pump uses check valves. Check valves allow flow in one direction.
Why would a engine have no compression on one cylinder?
most likely a valve is not seated,burned or 'missing'.. i.e 'dropped valve' this swopuld have made an obvious noise when it happened! if any of these are happening, the piston chamber will not seal... hence no compression.. another possibility is a hole in the piston itself ...
How do 4-cycle engines work?
4 cycles consist of: Intake cycle Compression cycle Ignition cycle Exhaust cycle Intake cycle - piston in lowest position intake valve open allown atomized fuel to enter combustion chamber Compression cycle - piston in upward stroke compressing atomized fuel mixture All valves closed Ignition cycle- Spark is introduced to combustion chambeer blowing piston back down in chamber valves closed Exhaust cycle- exhaust valve open piston rises in chamber to expel spent gasses.
What is the function of cumbustion chamber?
The combustion chamber has an exhaust valve and an intake valve. The power stroke is ignited just before TDC, in timing with the spark plug to ignite the fuel/air mixture. Hence, this forces the piston down with both valves closed. NOTE:Intake stroke (valve open to receive the f/a mixture), Compression stroke, both valves closed, Power stoke (see above), Exhaust stroke (piston upwards, with only exhaust valve open.
Is the 2.4 engine in the 2004 PT cruiser an interference fit between the valves and piston?
Valve to piston, no. The interference is valve to valve.
When the timing belt goes on a 1993 1.9 liter ford escort engine goes does it damage the top end of the engine?
It can. If one of the valves was in the combustion chamber at the time and the piston came up, it could damage the valve train and the top of the piston.
How does the intake valve work?
The intake valve opens as the piston is going down. It lets in an air fuel mixture. The valve then shuts as the piston reaches the bottom.
What occurs in each combustion chamber during operation of a 4-stroke-cycle Otto engine.?
Away-ward motion of piston draws Fuel-Air mixture into chamber via Intake Valve (Exhaust Valve closed).Intake Valve closes as piston begins toward-ward motion (Exhaust Valve still closed).Fuel-Air Mixture compresses as piston continues motion to maximum-squeeze extent of motion towards combustion chamber.Just before maximum compression of Fuel-Air Mixture (also called BTDC), Spark Plug "fires" to produce spark across its cathode-anode gap and ignites Fuel-Air mixture causing rapid burning and (now) gas expansion.Piston is forced away from Combustion Chamber with explosive force.Usable force of burning, expanding gas has been expended as piston reaches maximum distance from Combustion Chamber.Inertia and impulse from other cylinders causes piston to reach limit of travel away from Chamber and, then, to begin travelling back towards Chamber (and towards TDC) during which Exhaust Valve begins to open (Intake Valve closed).Reducing cylinder volume as piston continues toward TDC causes burned combustion products and unburned fuel product from previous plug firing out of the Chamber via the now-fully-opened Exhaust Valve.Piston reaches TDC, at which point Exhaust Valve closes, then reverses direction and begins travelling away from chamber again under its momentum as well as impulse from any other cylinders via the crankshaft to which pistons are connected in the crankcase.As Piston travels away from Chamber, Intake Valve opens, drawing in fresh fuel mixture and beginning a new cycle (starting again at 1. above). So what you have then is a description of Combustion Chamber status during each "stroke" portion of the 4-stroke-cycle (Otto) internal combustion engine:Intake (10. and 1. & 2. above) of fuel mix into ChamberCompression (2. & 3.) of fuel mix in ChamberExpansion (4. - 7.) of exploding fuel mix in ChamberExhaust (7. - 9.) of fuel mixture from Chamber
Why is there oil on your spark plugs?
bad valve seals, bad piston rings bad valve seals, bad piston rings
Does a piston check valve open because of pressure or flow under the piston?
NO IT WILL NOT OPEN.....
What is function of a piston in a petrol engine?
Answer The piston is a key engine part, which is used to compress gases withing the combustion chamber or cylinder of an engine. The piston is sealed with a piston ring, often constructed under freezing temperatures, to allow expansion and therefore complete sealing, to seal the chamber to prevent leaks, or dangerous gases escaping. As the piston moves downwards, a valve opens to allow fuel into the chamber, this fuel is then compressed, combusted and expelled. All of which is transferred through the cam or prop shaft, through a differential and gear box, into the axle and ultimately onto the road via the tire.
