Derek R. Posted July 5, 2018 Report Share Posted July 5, 2018 (edited) 2 hours ago, Ray T said: Top dead centre, when the piston is at maximum upward travel. Fuel is usually injected at a few degrees before TDC so it gets compressed before ignition. Top Dead Centre as Ray says, is when the piston is at the top of its travel within the cyinder. As to zero timing, it's not an expression I have heard before, but will presume it means the fuel is injected at TDC rather than a few degrees before. Generally, the reason why fuel is njected a few degrees before, is to allow the flame spread from the injector nozzle, or the spark plug in a petrol engine, to reach the top of the piston at the TOP of its travel. The momentum of the flywheel then carries the crankshaft with the piston attached so that the maximum expansion of burning gas pushes the piston downwards on the power stroke. Slow revving engines such as the JP2 might benefit from zero timing due to their slow movement compared to a petrol engine or higher speed diesel, and thereby possibly reduce bottom end bearing life. But I'm no Lister engineer, and there may be a more technical reason for timing the engine so. PS Nice looking boat. Bit posh for me though. Edited July 5, 2018 by Derek R.

I've just had a brief goggle for "zero timing" in relation the diesels and there are no meaningful results for that term, so the advertiser has perhaps either heard it wrong or been bamboozled with gobbledegook by the uncle.

roland elsdon Posted July 5, 2018 Report Share Posted July 5, 2018 I bought her 70 ft sister in 2000 for 72000, and sold in 2006 for about the same. 85000 is about the same. Apparently shes 6.10 because when rebottomed a strip was removed. Dont know what that would do to the framings. Her sister went everywhere a 70 ft can go. Strangely im suddenly currently asking 85000 for my boat. Link to comment Share on other sites More sharing options...

Derek R. Posted July 6, 2018 Report Share Posted July 6, 2018 (edited) Searching for spill timing on the JP2 has come up with some results, though I still have no idea what 'zero' timing is. It may even refer to the point at which the injector pump STOPS injecting fuel. However, 18° - 20° BTDC (before top dead centre) seems to be the point at which the injector pump should begin to pump fuel to the injector. More info: http://www.utterpower.com/lister_s.htm Scroll down to past the images for spill timing. It should be noted that this is for CS engines, though the same timing figures for a JP (Joint Productiom between Lister and Ruston Hornsby) appear elsewhere. http://www.oldengine.org/members/diesel/Articles/rrchapt6.htm Scroll down just past halfway for FUEL PUMP TIMING. 20° BTDC seems optimum. Lastly, there are manuals available through Winget: http://www.winget.co.uk/document/LISTER ST WORKSHOP MANUAL.pdf Though it was flagging a 25 minute download, so I didn't wait. NB: Most of my petrol engined vehicles are timed at static around 8° - 10° BTDC, and around 30° at 3000rpm and controlled by the automatic advance and retard mechanism. Such a mechanism is (I believe correctly) not fitted to old diesel engines! So we have a difference of volatility of the fuel used which will almost certainly affect burn rate and flame travel between diesel and petrol, as well as the rpm attainable. The twin plugged Guzzi engine will require slightly less advance due to two plugs firing the fuel, but not by a great deal. Edited July 6, 2018 by Derek R.

Yep. Zero-timing is a General Aviation expression meaning that a component (engine, gearbox, CSDU etc.) has been rebuilt to the extent that it now has an authorised installed life the same as a new part and when installed the log card records zero hours used. Doesn't mean you will get all the authorised life though! IIRC a helicopter engine of my acquaintance had an authorised life of 1200 hours. The actual mean time between replacements was well less and to get one to 900 hours was worthy of a party.! N Link to comment Share on other sites More sharing options...
