Although I have done pulse monitoring over the years loads of times using diagnostic equipment I have to confess that in attempting to crack this manually overnight I find myself struggling. The only addition to yesterday is I think the factor 60 comes into this calculation to convert the reading ba...

Good one, that saves me ringing you at 3 am to confirm whether I was right or not. Get some sleep now tonight maybe. But what's the conversion factor? That's the million dollar question. Four stroke scenario in my head, crank turns twice in four stroke cycle for one injection pulse felt. So crank tu...

Pinkies clamped around an external injector pipe feeling the distinctive pulses when injection takes place in that pipe? We have a machine that's about fifteen years old at work which does this, does rpm, injection timing, pulse duration, pulse width and measures the acoustics therein. Will dig it o...

Nearly there, Hall effect square waveform pattern? Crankshaft angle sensor which doubles up on a lot of engines as a speed sensor, read rpm straight from the horses mouth. Camshaft angle sensor which obviously runs at half the crank rpm, your pulse theory nearly there, times the result by two to get...

Or the other CAS times two?

CAS.

I bet you would be glad to go back to the old days ref price of beer/woodbines/petrol coupled with today's money though. Still got my MF SSB licence from 1973 but haven't used 2182 Mz for years. Like BP said link calls via Niton and Portishead long gone, last MF set I had was 14 years ago and it see...

Full ahead both then for the gas conversion boys, but is the grass " greener " or not? The subject seems to be gaining in momentum over here in the UK / EU. Seems a leaner burn, cleaner emissions even before CATS / Scrubbers etc but more expensive again. Seeing black clouds over the horizo...

Thanks JK, poor old Bill H has long gone but Dennis L is still around aged about 75 now and playing bowls which ironically was one of his sneering pet hates " all right for old b stards " he used to say, " old mans game ". Weird how it all turns round. I will know if he has read ...

Years ago I remember major gas turbine manufacturers on aircraft offering monitoring services, loads of sensors on the engines transmitting readings to the cockpit and thence automatically to a ground station and thence if you paid for it back to the engine manufactures. Great emphasis was placed on...

Anchored off in the lee of bum island reflecting of recent happenings at work resurrected perhaps past performances of items still photographed firmly in the back of the old brain. Looking back on it all, so many many engine hours ago on my counter of life this one certainly seems to stand out more ...

Mark Two model is for internal crankcase use age whilst underway. Peering through the oil mist, counting the droplets and looking for hot spots. Seeing whose oil manufacturer is the best and most dense when under load. Putting relief valve manufacturers on crankcase doors out of business. Really see...

Maybe they steamed over an old treasure laded Spanish flagship with hundreds of millions worth of gold on board and with the sea suction those things pull drew a few bars on board and the super efficient impeller mashed it all up and Via leaky O rings on an engine oil cooler entered the lub system? ...

Well that's just about the most descriptively titled speech that I ever heard about the mighty city of London to date, methinks the jury are still out on this one. Dunno when your next visit is due but you better have a good incognito jobby on board or you could well be in the sh one t here.

Not convinced that this non duplex chain drive is entirely Gorviendo valve oscillation free here? Anyone?
