Both the distributor and the camshaft must be timed to the top of the piston stroke.
* The camshaft controls the valve operation, and valves must be timed to open only when there will be optimum gas flow (both air/fuel mixture during the intake and exhaust gas flow during the exhaust cycle) * The distributor (or whatever other ignition timing scheme is used) must be timed to fire at the top of the compression stroke so that the engine will extract the most usable power from the combustion process. Note that ignition timing is dynamic, meaning that ignition timing changes as the torque and speed demands change.

What causes no compression in a 2 stroke dirt bike?
No compression could be various things from your piston to your crank start with your piston by doing a compression test
How can you tell if your on the compression or exhaust stroke?
You can determine if you're on the compression or exhaust stroke by observing the position of the piston and the alignment of the crankshaft. When the piston is at the top dead center (TDC) and both valves are closed, it's the compression stroke. Conversely, if the piston is moving down from TDC and the exhaust valve is open, then it's the exhaust stroke. Additionally, you can feel for air pressure at the spark plug hole during the compression stroke.
Which piston stroke of the four stroke cycle prepares (squeezes) the fuel mixture for combustion?
The piston stroke that prepares the fuel mixture for combustion in a four-stroke cycle is the compression stroke. During this stroke, the piston moves upward in the cylinder, compressing the air-fuel mixture that was drawn in during the intake stroke. This compression increases the temperature and pressure of the mixture, making it more conducive to ignition when the spark plug fires.
Which type of the engine brake uses the compression stroke of the piston as its retarding stroke?
You're talking about an engine compression brake, commonly referred to as a Jake Brake.
Where should the cam position be when setting timing marks on a 1994 Honda Civic 1.5L sohc?
#1 piston should be at TDC and both valves closed (compression stroke)
What are the Strokes of the four-stroke cycle?
The four-stroke cycle consists of four distinct strokes: intake, compression, power, and exhaust. During the intake stroke, the piston moves down, drawing in a mixture of air and fuel. In the compression stroke, the piston moves up, compressing this mixture before the spark plug ignites it during the power stroke, which forces the piston down. Finally, in the exhaust stroke, the piston moves back up to expel the burnt gases from the cylinder.
What is the compression ratio for an engine?
It is the volume of the cylinder/combustion chamber/head gasket/piston volume(dish/dome) when the piston is at the bottom of the stroke divided by the volume when it is at the top of the stroke.
How does a 4-stroke engiene work?
A 4-stroke engine operates through four distinct phases: intake, compression, power, and exhaust. During the intake stroke, the engine draws in an air-fuel mixture as the piston moves down. The piston then compresses this mixture in the compression stroke, followed by ignition during the power stroke, where the burning mixture forces the piston down. Finally, in the exhaust stroke, the piston moves back up to expel the exhaust gases, completing the cycle.
Is top dead center the compression stroke?
Top dead center (TDC) refers to the position of a piston at the highest point in its cylinder. It can occur at the end of both the compression stroke and the exhaust stroke, depending on the engine cycle. During the compression stroke, the piston moves upward toward TDC, compressing the air-fuel mixture before ignition. Therefore, TDC is not exclusively the compression stroke; it is a position that can be reached at different points in the engine cycle.
Compression ratio of the internal combustion engine is defined as?
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
Differences between 2 stroke and 4 stroke engines?
Two strokes have two cycles the piston go through intake/compression and ignition/exhaust where four strokes have four separate piston cycles intake compression ignition and exhaust.
