Hello
ok
I didn't really know how a direct petrol injection worked.
I thought it resembled diesel: injection just before the spark.
thank you for the explanations.

elsewhere on the technical review of my car (205d 1985), it is noted:
in case of extreme cold, you can put kerosene in diesel.
especially no petrol!

Why?

something else: andré, you have heated the diesel on one of your cars
this decreases the knocking and must reduce the unburned.

someone has the ideal intake air and fuel temperatures on diesel engine?

Hello
When you reheat the diesel it is preferable not to exceed 80c but in general seen there, important return on certain engine and that one uses the coolant of cooling of the engine which is at 90c one cannot hope more than 60c, unless to have a large size exchanger.
What happens if you overheat the diesel is the expansion of the internal parts of the pump, so slightly more play and less than it is old it oozes diesel between the piston and the body of the pump.
Reheating diesel results in more efficient operation
gentle less banging especially in very cold weather and a slight gain on consumption, but a slight loss on maximum power. (tractors that make shooting competitions at fairs
they do the opposite it cools the diesel to inject more, it's impressive to watch and hear!)
