FW: Electronic fuel Injection Worthy of Nobel Consideration?

Yeah, seeing is believing. I
would’ve expected the injectors to be closer to the spark plugs though as
both are at the cylinder heads. Still, I wonder if Chrysler knows how insanely
reliable that design has proven to be.


When and where’s lunch next week?

From the
Things-that-make-you-go-hmm department:.

 

It remains to be seen if my 1994
Dodge Ram 250 van is fuel injected or not. Tim McLean, Service Manager for
Helfman Dodge here in Houston swears it is, and Chrysler’s build record
(sort of the van’s birth certificate) bears him out. On the other hand,
the Crown Dodge salesman said nothing about fuel injection when I bought the
van new. Electronic Fuel Injection is something automotive manufacturers like
to crow loudly over, because it does improve engine performance. Virtually
every vehicle with EFI has at least one placard proclaiming its presence,
sometimes obnoxiously. Not mine. Not even a “Magnum” placard, as
the build record indicates the van to be. Computers weren’t controlling
the engine builds in 1994 so something could’ve been switched in the
paperwork.

 

At least that is my theory, and
I’m betting Tim lunch over it. The only way to determine if EFI is there
is through skilunking into the innards of the engine compartment for a couple
of hours. So the van goes back to Helfman tomorrow for the day. The good news
is that Helfman narrowed the problem down to cylinders 7 or 8. If EFI is
present, it’s one or two malfunctioning injectors. Expensive, but not
like a computer!

 

The thing I find amazing is that,
if my van has EFI, whoever designed those injectors is long overdue for a Nobel
Prize, because even Mercedes

EFI needs regular maintenance.
Injectors are really just electrically-fired atomizers, and they are prone to
clog. If I have injectors still purring after 120,000 miles and 14 years of
neglect, that designer is a god! J
