Injected engine start
Hi There
Problem with very cold starts is that the engine may well be much colder than the ambient (cold soaked) and therefore may be in the 'pre heat' regime.
I did a test the other morning at 10 am when the oat had risen to 9deg,yet the engine was still at 3.
Does your start procedure require the electric pump to be left on or should it only be used for priming then switched off.On some systems leaving the electric pump on will provide too much fuel once the engine is cranking.
I always find that a fan heater into the cowling for 30 mins before start on very cold days gives a great start as is gives the intake system a bit of help to keep the mixture as a vapour not petrol droplets.
Does the engine have separate priming lines operated by a ki-gas pump !,or is this electric aswell.
