How tdc and bdc setting?
TDC (Top Dead Center) and BDC (Bottom Dead Center) are critical reference points in an internal combustion engine's cycle. TDC is the position where the piston is at its highest point in the cylinder, while BDC is where it is at its lowest. These settings are used to determine ignition timing, valve timing, and overall engine performance. Properly aligning TDC and BDC ensures optimal engine function and efficiency.
The distance from TDC and BDC?
180 degrees Stroke.
How many degrees of crankshaft rotation are required for a piston to travel from tdc to BDC and return to tdc?
90
The distance the piston must travel from TDC to BDC is referred to as the?
stroke
The distance the piston must travel from tdc to BDC is referred to as the of the engine?

What can cause cylinder compression in new engine?
The movement of the piston from BDC to TDC.
What does bdc stand for on a bank statement?

Port timing diagram for two stroke diesel engine?
PORT TIMING DIAGRAM FOR 2S ENGINE Aim : To draw the port timing diagram of given two stroke cycle petrol engine . Apparatus Required : 1. Two stroke petrol engine 2. Measuring tape 3. Chalk Theory and Description : In the case of two stroke cycle engines the inlet and exhaust valves are not present . Instead , the slots are cut on the cylinder itself at different elevation and they are called ports. There are three ports are present in the two stroke cycle engine . 1. Inlet port 2. Transfer port 3. Exhaust port The diagram which shows the position of crank at which the above ports are open and close are called as port timing diagram. The extreme position of the piston at the bottom of the cylinder is called " Bottom Dead centre " [BDC] . The extreme position of the piston at the top of the cylinder is called "TOP dead centre " [TDC ] In two stroke petrol engine the inlet port open when the piston moves from BDC to TDC and is closed when the piston moves from TDC to BDC . 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 . The exhaust port is opened , when the piston moves from TDC to BDC and is closed when piston moves from BDC to TDC . The exhaust port opening and closing are measured with respect to the BDC. Procedure : 1. Remove the ports cover and identify the three ports . 2. Mark the TDC and BDC position of the fly wheel . To mark this position follow the same procedure as followed in valve timing diagram . 3. Rotate the flywheel slowly in usual direction (usually clockwise ) and observe the movement of the piston 4. When the piston moves from BDC to TDC observe when the bottom edge of the piston . Just uncover the bottom end of the inlet port . This is the inlet port opening (IPO) condition , make the mark on the flywheel and measure the distance from TDC 5. When piston moves from TDC to BDC observe when the bottom edge of the piston completely covers the inlet port . This is the inlet port closing (IPC) condition . Make the mark on the flywheel and measure the distance from TDC . 6. When the piston moves from TDC to BDC , observe , when the top edge of the piston just uncover the exhaust port . This is the exhaust port opening [EPO] condition . Make the mark on the flywheel and measure the distance from BDC . 7. When the piston moves from BDC to TDC , observe , when the piston completely cover the exhaust port ,. This is the exhaust port closing condition [EPC] . Make the mark on the flywheel and measure the distance from BDC . 8. When the piston moves from TDC to BDC observe, when the top edge of the piston just uncover the transfer port . This is the transfer port opening [TPO] condition . Make the mark on the flywheel and measure the distance from BDC 9. When the piston moves from BDC to TDC , observe , when the piston completely covers the transfer port. This is the transfer port closing [TPC] condition . Make the mark on the flywheel and measure the distance from BDC . Note : 1. The inlet port opening distance and closing distance from TDC are equal . 2. The exhaust port opening distance and closing distance from BDC are equal . 3. The transfer port opening distance and closing distance from BDC are equal . Result : The port timing diagram for the given two stroke cycle petrol engine was drawn.
What does BDC stand for?
Bottom Dead Centre
What takes place during each stroke of a four stroke engine?
Stroke 1: Intake, as piston moves downwards from top dead center (TDC) to bottom dead center (BDC), it draws in the air fuel mixture through the intake valve.Stroke 2: Compression, with both valves closed, the piston moves upwards from BDC to TDC, compressing the air fuel mixture.Stroke 3: Combustion, with the piston at TDC, the spark plug ignites the air fuel mixture, forcing the piston down to BDC, this is also called the power stroke.Stroke 4: Exhaust, the exhaust valve opens and the piston moves from BDC to TDC, forcing the exhaust gases out of the cylinder.Summary: Suck, Squeeze, Bang, Blow
How many degrees of camshaft rotation are needed for a piston to travel from tdc to BDC and return to tdc?
A camshaft would travel 180 deg for every 360 that the crank turns.
