What is bottom dead center on an engine?
Bottom dead center is the point at which the piston of an engine is nearest to the axis of the crankshaft. On a vertical engine, this is the lowest point that the piston reaches. During the compression stroke, the piston moves up from bottom dead center.
What is meant by t DC and BDC in a suitable sketch mark the two dead Centres?
In a reciprocating engine, the dead centre is the position of a piston in which it is either farthest from, or nearest to, the crankshaft. The former is known as Top Dead Centre (TDC) while the latter is known as Bottom Dead Centre (BDC).
What does BDC stand for in engines?
Four-stroke engine The charge of air and fuel is induced into the engine cylinder as the piston moves from top-dead-centre (TDC) to bottom-dead-centre (BDC).
Is piston at the bottom of its stroke?
The piston starts its downward stroke (it moves from the TDC towards the BDC). Since the supply port is open, the fluid at the supply pressure (in the absence of pressure losses through the port) enters the cylinder.
What does BDC stand for?
Business Development Center
The goal of the Business Development Center (BDC) is to develop sales and service business for the dealership.
What makes up the bottom of an engine?
Consequently, It is made up of a whole list of engine bottom end components. Consequently, All of these engine bottom end components must work together properly to form a healthy engine. So, A lot of research has been made, to improve performance of automobile engines, by improving engine bottom end components.
How to turn in the direction of an inoperative engine?
One key to performing the turn correctly is to keep the turn coordinated with the ball moved approximately 1/2 out of the center marks – “uncage the ball” – in the direction of the good engine. This will ensure no sideslip in the turn.
Where are the engines located on a boat?
An outboard motor is a self-contained unit that includes the engine, gearbox and propeller, mounted on the boat’s transom sitting outside the hull at the back of the vessel. In addition to providing propulsion, outboard engines also provide steering control by pivoting and controlling the direction of the thrust.
Why do you not turn in the direction of a good engine?
The purpose of the banking toward the good engine is to stop the turn that would otherwise result (due to the rudder sideforce) when the ball is in the optimum position, NOT to influence the amount of sideslip that is present.
When does the piston travel from top to bottom in an engine?
A phase of the engine’s cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa.
Which is the major thrust side of the engine?
As viewed facing the front of the engine, if the crankshaft is rotating clockwise, the major thrust face is on the left side of the cylinder (the exhaust sides of the right/ passenger cylinders; and the intake sides of the left (driver) side cylinders. The minor thrust side experiences force on the compression stroke.

Where is the engine located in a front wheel drive car?
Don’t laugh: on a front-wheel-drive car, your engine could be located at the front left or front right, depending on where the transmission sits, and the engine could be in the rear of the car if you’re driving a Porsche or a VW bug. Once you figure out the oil is dripping from the engine, all you have to do is pinpoint the leak.
