  • Man dies in bike explosion !

    A 40-year-old chartered accountant, Vipul Gada, died hours after he suffered severe burns in a blast that occurred when he was trying to kick-start his bike. The two-wheeler was parked on the premises of his building in Parel. The incident occurred around 9.50am on Thursday.

    The Bike was Yamaha and still in inspection of what caused the Blast.

    Approved!

    Sad news indeed. Overheated carb leading to heating/ignition of petrol and eventual explosion?

    May he R.I.P and god give his family the strength to sail through rough tides.


    B.T.W - The news reports it happened on 29th March last year!

      Very sad incident! The news was published on Mar 29, 2013 in TOI. I remember one of my friends sharing the same with us in office.

          Strange! how does carb overheated in this incident which leds to explosion and causes the death of this man.

                WTF!! how will the carb get hot to an extent that it might ignite?...
                btw before cleaning my carb the fuel tank used to heat up like hell in peak traffic, i could feel the heat through my thigh even with a jeans, but the heating has reduced after cleaning the carb....now the oil is 4k old yet it wont heat up like before..

                  Explosion of a carburetor or a gas tank can only occure if these parts are leaking or there was any heat source nearby, or some electrical malfunction in the bikes electricals, but still it's not beliveable.After the incident one can only assume of what might have happened.

                      Yes, I questioned that myself.
                      Carb wouldn't overheat in the morning at that time, I suspect that the technical 'expert' wasn't .
                      We have millions of 2 wheelers in the country which run safely every day without 'overheating' carbs.
                      These could have been two issues at the same time. It could have been a minor fuel leakage through the tank/pipe (or a corroded/leaky tank). Petrol vapour is very flammable, hence while kicking, if there was a spark anywhere due to improper earthing or a defective plug cable, there is every chance of the vapour combusting and causing an explosion.
                      I doubt the carb had anything to do with it.

                        Intake valve stuck open can bring the flame front to fuel in carb. This type of carb flame has been seen by me personally due to improper cam timing , in zen inline 4 while i was trying to tune it. If cam is keeping the intake valve open while spark is produced , flame front travels far down the inlet manifold.
                        In this case looks like inlet valve failed to close , not timing problem but guide failure / return spring failure or valve seat failure.

                        Petrol actually has very high flash point. It does not catch fire just due to temp , else who would need a spark plug.

                        I am sure police expert will come out with a theory which does not hold manufacturer responsible. No manufacturer will own up , not in india!

                          Police experts in India has only one theory for this kind of incidents, that it was short circuit in the vehicle wiring simple as that, on the other hand company won't even bother to look into the incident, infact these companies don't even listen to the daily problems of the consumers regarding there product so who's gonna listen or investigate such bizzare incident.

                            valid theory, might have happened this way.

                            although theory is good, in my opinion, it seems remote possibility for two reasons -

                            if intake valve stuck and flame front did move along intake manifold, it has to cross the carb or FI unit and then cross the fuel pipe and reach the petrol tank, and it will take some time, coz explosion can only occur in tank when petrol burns and pressure is created. even if carb catches fire, it should only burn and not explode.

                            second if intake valve was jammed, that means overhead cam should also jam leading to everything jammed and open valve may also hit piston, thereby jamming everything and the person should not be able to kick the bike anymore. just a theory.

                              Prince bhai, I have zero clue as to how it may have happened. But I feel that given the inflammability of petrol, it'd hardly take a blink for enough gases to be created to rip through he tank.
