Now as any rationale-thinking person would react, never mind Star World
TV programs like ‘When Cars Attack’ – I asked Suzzanne
for some more info and gathered the following:
Q1) When the Car stalled while attempting to over take on the up-gradient
- what was the engine temp indication like and for how long had you been
driving non-stop ?
A1) The engine temp was normal and we had started out from Goa at 6 am.
The time our car stalled out on us was 10 am, but before that, say at
around 9 am, we took a small break of about 10 minutes.
Q2) What was the passenger/baggage load like at that time ?
A2) Passenger load - just two of us. Baggage load - hardly any - only
one suitcase with two carry bags or some such thing.
Q3) In what gear were you attempting to overtake and was the Car pulling
well or just struggling ?
A3) We were in the 1st or 2nd gear (if my memory serves me right –
2nd more likely) and no, the car was not struggling. On the contrary,
it was pulling well ! And then suddenly... it just died out on us !!
Some basic reasons behind stalling of a running engine
Armed with all the above details, let’s first keep the following
in mind – for a Carb as well as an Mpfi Car :
1) Loss of ‘effective’ Fuel Supply ‘into’ the
Cylinders – for whatever reason.
2) Likewise, loss of correctly timed Ignition pulses to the Spark Plugs.
3) Overheating/Head Gasket failure due to any cause.
4) Engine Seizure – either due to Lube System or Material Failures.
5) Water ingress into the Cylinders via Air Intake – such as while
crossing rivers etc.
In Suzzanne’s case, going by her narration that the ‘car
just died out’ – thus assuming without any ‘splutter’
+ the fact that it subsequently could start in the normal way –
to me the possibility of a ‘transient’ Ignition System failure
appears strongest. For if it had spluttered too before dieing out, it’d
have meant that it was gasping for fuel but the Ignition was there.
