You're talking about an engine compression brake, commonly referred to as a Jake Brake.
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.
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.
Well if you lined up the timing marks properly then it would not matter. The engine would run anyway.
As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.
The power stroke. The order is intake, compression, power and exaust. The piston moves down on intake and power but is only forced down on the power stroke
No compression could be various things from your piston to your crank start with your piston by doing a compression test
Depends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust strokeDepends on if this engine is a 2 stroke, 4 stroke, or rotary engine.

There is only one intake stroke in a four-stroke engine. The other three strokes are compression, power, and exhaust. The intake stroke is a down stroke of the piston in which fuel is drawn into the cylinder while the fuel intake valve is open. The next stroke is the compression stroke in which the valves are closed and the fuel is compressed for combustion. The following stroke is the power stroke - a downward stroke of the piston after fuel combustion that drives the crankshaft. The final stroke is the exhaust stroke, an upward stroke of the piston as the exhaust valve opens to relieve the exhaust fuel fumes.
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
There is no separate compression stroke on a 2 stroke engine, but there is compression - the intake and compression take place on the same staroke, the intake on the first part and compression on the later part.
Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
