Re: Strange Ping Issue

Strange Ping Issue

A name brand injector cleaner every few months solved my pinging
issues in one of my trucks.

Not sure how to cure the dog farting noises from my diesel's exhaust
when idling though.

Diesel and fuel injected engines don't ping. Diesels have
pre-detonation and fuel injected engines have computahs that adjust
the timing to just before it starts to ping. However, if it's a
conventional infernal combustion engine, either retard the timing, or
use higher octane fuel.

My 83 Dodge D50 diesel used to do that. I replaced the muffler and it
was still there but nowhere near as loud.

This isn't universally true - though with diesels its commonly called
'knocking'. By the way in the UK we call the noise petrol engines
make 'pinking' for some reason

Bwahaha! My 1954 landrover 2.6 Ltr diesel does certainly not have a
computer....

I sold my 1970 Series IIa last year. However, it was a petrol engine.
My 1983 Dodge D50 diesel also didn't have a computer. The most
complex electronic was the glow plug timer. Anyway, I was referring
to a modern diesel engine, which has all the modern technology, and
pays for it in lousy diesel mileage.

A dead car parked in front of the house is a local status symbol. I
had two for a while, but am down to only one dead car at the moment:

Injected engines usually don't ping, but under some conditions they
might do it for a slight bit before the electronics detect the pinging
and retard the ignition.

The higher the octane, the more the detonation is delayed.
The higher the ceptane, the faster the diesel fuels detonation.
The higher the prozac, the slower the detonation.

Are you certain? Diesel has a cetane number, not ceptane.

Yeah...sorry...haven't used the word in years.
