Hi sir, i'm really happy to come across with your channel. I'm now a student pilot and we study AGK right now. So, it is not enough for me to be content with just theoretical information without seeing how it works really. Thank you very much for sharing your knowledge and experience. I dont quite understand what causes pump to move. It said camshaft eccentric but as i see the pump not located on the engine block. So, can you explain a little bit about location?
Hi there, thank you for your post. The eccentric camshaft is an off centre lobe built onto the main engine camshaft. The rocker arm of the pump sits inside the engine with the eccentric camshaft sitting on top of the rocker arm. As the main engine camshaft rotates the lobe (eccentric camshaft) also rotates. If the eccentric camshaft wasn’t eccentric, I.e. it was perfectly round it would just rotate on top of the rocker arm of the pump and the rocker arm wouldn’t move at all. Because this camshaft is eccentric in shape (off centre), it presses down on the rocker arm on each rotation. This makes the rocker arm move up and down and in turn forces the diaphragm to move up and down, sucking fuel through the intake valve and out through the outflow valve. I hope this helps you understand this a bit better. Good luck with all your studies and best wishes on your journey to become a pilot. Please have no hesitation in reaching out if you need any more help with your AGK. Regards, Roy
