What part causes the valve to rise and fall opening and closing the ports on a engine?
The valve's rise and fall, which opens and closes the engine ports, is primarily controlled by the camshaft. As the camshaft rotates, its lobes push against the valve lifters or tappets, causing the valves to move upward and open the ports. Springs then pull the valves back down to their closed position when the cam lobe rotates away, ensuring proper timing for intake and exhaust processes. This coordinated movement is crucial for efficient engine operation.

Are the heads on a 65 289 motor reversible?
No, the heads on a Ford 289 motor are not reversible. The cylinder heads are designed to be installed in a specific orientation to match the intake and exhaust ports on the engine block. Reversing the heads would result in misalignment of the ports and poor engine performance.
What is IO PORTS?
I/O ports, short for Input/Output ports, are physical interfaces on a computer or device that allow the exchange of data with external devices. These ports can be used for connecting peripherals such as keyboards, mice, printers, and storage devices to a computer. There are different types of I/O ports, including USB, HDMI, Ethernet, and audio ports.
Which state have maximum number of ports?
Texas has the maximum number of ports in the United States, with over 1,000 miles of coastline and numerous ports, including the Port of Houston, which is one of the busiest in the nation.
Russia has few ocean ports that are?
some of the largest and most strategic in the world, including ports in cities like St. Petersburg, Vladivostok, and Novorossiysk. These ports play a crucial role in facilitating Russia's trade with other countries and are important for both military and economic purposes.
How is it possible for ships from ports over 1000 miles inland to sail to ports around the world?
Ships from inland ports can reach the ocean through interconnected waterways, such as rivers, canals, and locks. Once they reach the ocean, they can sail to ports around the world using established international shipping routes. Navigation technology and infrastructure make it possible for ships to travel long distances across oceans.
A forcible closing of ports?
is a blockade
Can side cam engine be installed in 4 stroke or 2 stroke engine?
sidecam engine cannot be installed in 2 stroke engine because in 2 stroke engine we have inlet & exhaust ports not valves... so when piston moves up and down it automatically opens the inlet and exhaust ports so it does not require any camshaft for opening of valves as it is required in 4 stroke engine
Closing of the Southern ports so supplies couldn't be shipped in or out?
Union Blockade
How do you close port 8080 on a Mac 10.6?
Closing internet ports are closed/open on the modem if you only use a modem or the router if you use a modem/router. Read you manual on the router or go to the manufacturer and you can down load the instructions there and/or look for the FAQ on closing ports.
What is a valve and where would you find them?
A valve is a device used to regulate the flow of fluids or gases by opening, closing, or partially obstructing passages. Valves can be found in various applications such as plumbing systems, water treatment plants, oil refineries, and industrial machinery to control the flow of liquids and gases in pipes and ducts.
What is term for a focible closing of ports?
A: Blockade - Cut off an area by means of troops or warships to stop supplies or people from coming in or going out; to close off a country's ports.
What causes shortages for the confederacy during the war in the southern ports?
Union's naval supremacy and blockade of Southern ports.
Which nation did japan sign the treaty of kanagawa opening ports for trade?
the united states
How can you differentiate between the inlet and outlet ports in an ic engine?
outlet ports are smaller to reduce the exhaust losses
What is Napoleon's policy closing European ports to British goods?
The Continental System which was a failed Economic Boycott against the UK.
What are the wired ports?
this is answer in view of IT and Ethernet port. Answer: An Ethernet port is an opening on computer network equipment that Ethernet cables plug into. These ports are alternatively called jacks or sockets. Ethernet ports accept cables with RJ-45 connectors.
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.
