Hi All
A few weeks back, well more like months, truth be told, I had a spare couple of hours and whilst gazing at my CS I was wondering about fine tuning.
On the theory that an engine in a high state of tuning would use less fuel I came up with a simple power meter that magnifies the movement of the injector pump fuel rack.
It's a simple cam that is directly connected to a pointer. there's a movable marker against the dial face, the idea being that before making any further adjustment the current rack position is marked with a fixed load, 500w lamp, immersion element, electric kettle, whatever is to hand.
After making an adjustment, IP timing, injector pressure, tappet clearance ect. any change in fuel usage when running with the same load, at the same revs, should be apparent.
Obviously it won't be the ultimate tuning device, but from the few minutes I spent playing with it it certainly detects extra load being applied, and I hope it will register the difference when using fuels other than dino diesel.
Since then other projects, log splitter, car port, local farmers livestock trailer, running a B&B ect, have got in the way so I've yet to put theory to the test but as the site is pretty quiet I thought I'd post up and see what sort of reaction it gets.........
Cheers Stef
