The term-term basis Engines

   The terms of the engine.

i) The Top One (CASH) - refers to the very top limit movement of the piston (TDC)
ii) The Ground Once (KBS) - Refers to the bottom limit of movement of the piston (BDC)
iii) Cylinder - Division in which the piston moves
iv) Hole (Bore) - The diameter of the cylinder
v) stroke - the piston movement of the KBS CASH or otherwise.
vi) Distance Running - The distance between the center of the crankshaft with the crank pin center
vii) Rounds per minute (PSM) - The number of crankshaft rotation per minute

Capacitance term engine

i) Burning Room - a room or area where the air is compressed in the cylinder
ii) The volume of displacement - The volume or space occurs when the piston moves from the CASH to the KBS.

iii)     Compression Ratio - The ratio in which the compressed air and fuel in the cylinder. See Figure 2.1.2.iv

Compression ratio =

	The clearance volume + volume displacement
	The clearance volume

Example calculation:

Given that the clearance volume and the volume displacement 10cm3 70cm3. What is the cylinder compression ratio?
Answer:
Compression ratio
But the compression ratio = 8:1
