........
I've heard that damage may occur if you coasted in a car while in gear. Not sure, but it had something to do with the emission systems (cat maybe ??). Anyway, I was wondering if anybody has ever done something like this to their Spyder, and if I did any long-term damage to our bike.
Thanks in advance....
If anyone is interested in the background behind all this..... :dontknow:
Back in the days of Carburetors & Mechanical (or even separately powered electrical) Fuel pumps on internal combustion engines, not only was there a significant risk of damage due to the lack of power and control, but there was a
BIIG potential for 'in the exhaust system' trouble if you shut off the ignition and continued coasting in gear before re-applying spark.... but quite a few people did it, and only
some of them ever got caught out & blew things up!! :shocked:
Then came emission control & catalytic converters etc, and that 'in the exhaust system' trouble changed, cos those cats
REALLY don't like raw unburnt fuel, so that added to the
potential for damage - and even when Fuel Injection first came out, before all of the electronic and computer controls that we have today happened along, it was still possible to get raw atomised fuel into the exhaust by coasting in gear with no ignition, where either heat (from the exhaust itself, or from the 'built in heat generator', the catalytic converter) or turning the ignition back on could cause it all to ignite and cause a pretty substantial '
bang' that
could but didn't often do some explosive damage, but it didn't take long to work that out, so some genius linked the fuel pump operation to the ignition circuit and with that, the risk was suddenly made a whole lot less than with those earlier fuel/spark systems.... but that unburnt or even partially burnt fuel in the exhaust
could still damage the catalyst on the catalytic converter so your engine emissions weren't quite so clean for ever after! :lecturef_smilie:
But these days, with Common Rail Fuel Injection Systems and computer timed fuel pulses that are matched with the injection pulses and fail-safes that cut not only the fuel pump output but also both the fuel injection and/or the spark if anything isn't timed right, it takes something
REALLY out of the ordinary (or someone who's really 'talented'

) to get raw unburnt or partially burnt fuel into the exhaust system and then re-ignite it.... that's not saying it
can't &/or
doesn't ever happen, it's just that there's
HEAPS of fail-safes built into the systems now that hafta either all throw in the towel at the same instant or they've
ALL gotta be subverted at that same instant somehow for anything really bad along the lines of what could happen with carbie'd engines & mechanical fuel pumps 'in the exhaust system' - and the risk of damage to the catalytic converter by un or partially burnt fuel has been massively minimised by all the controls & fail-safes too - so not only do we get
WAAAAYYY more power and better fuel economy from our modern engines, we also get less of the damaging emissions
AND there's virtually
NO chance of actually damaging anything 'in the exhaust system' of your modern vehicle by coasting in gear with the ignition off!!

hyea:
That's not saying there still isn't a significant risk of damage to you/your vehicle/other road users due to rolling along without power & reduced control :shocked: but accidentally flicking the Emergency Stop button on your Spyder isn't all that likely to do much 'internal' damage, just so long as you don't make a habit of it or let it continue for too long/too often!! :lecturef_smilie: So rest easy on that count - we've probably all done it, or will do it, without any significant issues (apart from in our shorts! :sour: ) but we do all try pretty hard not to make a habit of it! :thumbup:
