if auto related it stands for top dead center and refers to the position of the crank in relation to the positon of the number one cylinder.

How do you find TDC 2.2 L 4 cylinder?

To find the Top Dead Center (TDC) on a 2.2L 4-cylinder engine, first ensure the engine is off and safely secured. Remove the spark plug from cylinder number one (typically the front cylinder) to allow for easier access. Rotate the crankshaft using a socket and ratchet in the direction of normal engine rotation while feeling for the piston to rise. Once the piston reaches its highest point, align the timing mark on the crankshaft pulley with the TDC mark on the engine block, confirming that the engine is at TDC for cylinder one.

You must be at TDC on the Compression stroke.


What is the deg that the crankshaft timing mark what deg to set be for TDC?

The crankshaft timing mark is typically set at 0 degrees (TDC) for the top dead center position of the engine's first cylinder. This indicates that the piston is at its highest point in the cylinder, and both the intake and exhaust valves are closed. In some engines, the timing marks may be labeled differently, so it's essential to consult the specific service manual for your engine to ensure accuracy.


What is the compression ratio for an engine if each cylinder has a maximum volume of 500 cubic centimeters and a minimum volume of 50 cubic centimeters?

Compression ratio is exclusive to each cylinder, though they will all have the same result if they are the same dimensionally ( and they always are) > Divide the total engine capacity by the number of cylinders, this gives the capacity or swept volume of each cylinder (bore * stroke) > So in a 2.0 (2000 cc) litre 4 cylinder engine, each cylinder has a 2000 / 4 = 500 cc swept volume (bore * stroke) > The combustion chamber is the volume remaining at top dead centre (TDC) > Compression ratio = volume at BDC (swept volume + volume at TDC) / volume at TDC


What is the comparison of the volume of space between the piston's top surface and the top cylinder at BDC and TDC is called?

The answer is Compression Ratio. You should try reading the Study Unit it really helps!
