New ideas

Sometimes when you have a problem the best thing you can do is walk away from it. Well I am focused on this project again and some things caught my attention the second I loaded the CAD model today. For starters I am designing the engine block around the position sensors for the valve actuators. They are entirely too big and they rely on magnets. Entirely too much fluid must be displaced to move the valve actuator to a desired position and EMI would affect position sensor accuracy. I can miniaturize the whole system and solve these problems by going with a custom made position sensor. I'm off to start sketching out the new design and rebuilding the CAD model. Here are a few shots of the block before I begin redesigning it for a third time.
