Is the fuel is ignIted during the combustion cycle by the exhaust manifold?

Nope, the manifold carries out the burnt fuel air mixture (usually 14/1) then it enters the cylinder through the intake valve, then after the piston reaches the top on the compression stroke, your distributor connects the high voltage ignition coil to the spark plug wire, inside the cylinder the spark jumps across the gap between the electrodes of the spark plug and THAT is what ignites the fuel...
Now, if the timing is off, or the mixture too rich, some unburnt mixture could go into the exhaust manifold, and the high temperature there might cause it to ignite there, but that is caled a backfire, the noise is like a shotgun and flames go out the exhaust pipe and it may blow up your muffler, but that is very wrong, it shouldn't happen.

What can cause white smoke from the exhaust during acceleration?
coolant entering the combustion chambers, possibly thru head gasket, intake manifold, etc. What vehicle? 2005ford power stroke deisel
What does a egr valve do?
The EGR (Exhaust Gas Recirculation) directs exhaust gasses into the engine's combustion chamber via the intake manifold. The exhaust gasses are inert (do not support combustion) and displace oxygen that would normally be drawn into the engine during the intake stroke. Think of the engine as a vacuum pump and can only draw in a fixed amount of oxygen to be mixed with the fuel for ignition. The reason that exhaust gasses are drawn into the combustion chamber is to cool the exhaust. With less Oxygen in the fuel mixture the flame burns cooler and cooler exhaust temperatures result in lower NOX (oxides of nitrogen) emissions.
Will the exhaust manifold on a 99 Chevy S10 2.2 need to be removed during blown head gasket repair?
Yes, the exhaust manifold on a 99 Chevy S10 2.2 will need to be be removed during the blown head gasket repair.
Will a piston burn a hole in as a result of a binding exhaust valve?
A hole in piston is caused by extreme heat! most likely cause is coolant being introduced into the cylinder during combustion from a leaking head gasket,faulty intake manifold gasket or a defective cylinder head!
What are the functions ofengine inlet and exhaust manifolds?
Inlet manifolds are actually called intake manifold and this is to allow air to be injected into the fuel for either a rich or lean mixture for either performance or gas mileage (which can be adjusted). The Exhaust manifold is used to expel your burnt fuel, or air/fuel mixture, during the exhaust stroke on a 4-cycle engine to allow room for the intake stroke to bring in your fuel, or air/fuel mixture. The exhaust manifold simply directs the exhaust and become extremely hot. The exhaust is pushed out by the exhaust stroke.
What describes the position of intake and exhaust valves during the most powerful stage in a four-cycle gas engine?
-intake: exhaust closed, intake open -compression: exhaust closed, intake closed -combustion: exhaust closed, intake closed -exhaust: exhaust open, intake closed
What happens to a intake and exhaust valve during the power stage cycle in a four cycle gas engine?
If im not mistaken, during the power stage the intake and exhaust valves are both closed. the intake valve opens pulling air into the cylinder (cycle one) and the exhaust valve opens (cycle 4) to relase the air fuel mix that was ignited.
What causes gray smoke from exhaust?
grey exhaust smoke is caused by your engine burning oil during the combustion process. this could be caused by a piston ring that doesnt properly seal, or another leak in your engine.
Clicking tapping noise coming from driver side cylinder head increases during acceleration but decrease during idle or at stoplight?
I'd check the exhaust manifold first. A cracked manifold or leaking gasket can cause a sound that's a lot like what you describe.
What is the valve size in your set of heads?
Depends on the heads. The size is different for the exhaust valve and the intake valve, and different engines have different size valves. The valves are mechanical devices in the engine heads that open and close. The intake valve opens to let the air/gas mixture into the combustion chamber,. Both valves close the combustion chamber during the compression stroke, and the exhaust valve opens to let the burnt gas out during the exhaust stroke.
What is a diesel particulate filter?
It traps carbon particles from the exhaust stream of a diesel engine, and, during regeneration, serves as a combustion chamber to incinerate those particles.
What is humming in gas turbine?
The formation of combustion oscillations can occur during an operation of a gas turbine burner. This is also known under the concepts of "combustion chamber humming", "combustion chamber oscillations", "combustion-induced pressure pulsations", "oscillating combustion processes". The combustion oscillations are due to an interaction between the quantity supplied per unit time of combustion air/fuel mixture flowing in the flow duct of the burner. The mixture is ignited after entry into a combustion chamber and burns in a flame, with the momentary combustion conversion in the flame. Combustion conversion designates the quantity of combustion air/fuel mixture converted per unit time during a combustion process in a flame. Pressure fluctuations in the combustion chamber, which can lead to the formation of a stable pressure oscillation, can occur due to a change in the combustion conversion. In addition to an increased production of noise, the combustion oscillations cause an increased mechanical and thermal load on walls associated with the combustion chamber and on other parts belonging to the combustion system.
