Condensing unit for heat pump unit making knocking noise What causes my heat pumps condensing unit to making knocking noise?
There could be loosened internal mounts (connecting rods, pistons, pins, crankshafts or other related parts) in the compressor causing the banging or knocking noise. A simple call to a technician should resolve the issue.
What is meant by the knock range of an engine?
It is the octane number range the distributor automatic spark advance can handle without the engine knocking.
What is the reason for Knock in the diesel engine?
Diesel knock is generated due to fully advanced timing and retard conditions. If the timing is retard the fuel will not be burned purely and rapid pressure will be developed and pinking noise will be generated. In a advance condition the fuel is injected in to the combusion chamber before reaching the piston tdc the burning will start suddenly otherhand the piston is being compresses the charge. The combusion should be done at maximum pressure and temperature but in this case the fuel does not burnt at that stage (actually piston wants the load at that time)the pressure is not developing instanteniously rapid pressure developed thats why the diesel knock generates. Another reason for diesel knock if diesel does not have the good cetane number knocking will be generatedTHIS ANSWER HAS SUBMITTED BY LOHITHKUMAR S FROM TATA MOT0RS MANGALORE

Pinking scissors are called pinking shears because they create a zigzag pattern along the edge of fabric to prevent fraying. The zigzag pattern resembles the teeth of pinking shears, which is where the name comes from.
What the function of pinking shear?
Pinking shears create seam edges from fraying.
What does a knock sencor do?
A knock sensor listens for the 'knock' (or pinking), that shows that the fuel is exploding, rather than burning. Via the engine management computer, it retards the timing of the spark, until the knocking stops. 'Knocking' can damage valves and piston crowns, if allowed to continue. A knock sensor allows different grades of fuel to be used, without damaging the engine.
What element was added to gasoline to prevent knocking?
Compounds of the element Lead (Pb) was added to gasoline to help prevent pre-ignition, commonly known as "pinking" or "knocking". Environmental concerns required the introduction of non-leaded gasolines, which we have now. Modern cars use computer controlled spark timing and fuel injection timing to prevent pre-ignition.
What is pinking?

What cuts zig zag edges?
Pinking Shears
What is the name of zig zag scissors?
pinking shears
Are fabric scissors stronger than pinking scissors?
The difference between fabric scissors and pinking shears is not one of strength. Pinking shears are designed to give a zig-zag cut rather than a straight cut (which for some kinds of fabric will help prevent the cloth from unravelling into its constituent threads).
What are the Safety points of pinking shears?
Dont cut your fingers with them
What is the function of shear?

What are pinking shears?
Used to finish edges of cloth with a zigzag cut for decoration or to prevent raveling or fraying.
