What is BDC in bike?
BDC – Bottom Dead Center As it relates to cycling, BDC is when the cleat is at the furthest point away from you, which is also the point at which the leg is fully extended in the pedal stroke. In BDC, you are neither pushing on the pedal nor are you at the point where you are pulling back and up on the pedal.
Why is TDC and BDC important?
(a) The “Displacement volume” is the volume displaced by the piston as it moves between top dead center (tdc) and bottom dead center (bdc). This volume determines the capacity of the engine. The ratio of this volume to the swept volume determines the compression ratio of the engine.
What happens at BDC?
The piston reaches Bottom Dead Center (BDC). As the piston travels up the cylinder, the intake valve closes. The air/fuel mixture is compressed in the chamber. Near the top of the compression stroke, the spark plug fires.
What is a dead center used for?
A dead center (one that does not turn freely, i.e., dead) may be used to support the workpiece at either the fixed or rotating end of the machine. When used in the fixed position, a dead center produces friction between the workpiece and center, due to the rotation of the workpiece.
What does BDC mean in motorcycle jargon?
According to Timberwoof, the maintainer of the rec.motorcycles FAQ: BDC means Bottom Dead Center, the position closest to the crankshaft that a piston travels in its cylinder. Alternatively, Brain-Dead Cager (refering to a car, cage, driver that is not attentive to the road: especially motorcycles on it).
What is TDC and BDC in internal combustion ( IC ) engine?
Que: What is TDC and BDC in internal combustion (IC) engine? Ans: TDC (top dead center) means the upper most position of piston in cylinder & BDC (bottom dead center) means maximum lower position of piston in IC engine.
When does the piston move from BDC to TDC?
The transfer port is opened when the piston is moved from TDC to BDC and the fuel enters into the cylinder through this transport from the crank case of the engine . The transfer port is closed when piston moves from BDC to TDC . The transfer port opening and closing are measured with respect to the BDC .
What do you call a broken down motorcycle?
