Hi Steve,Road trip and hit a snow squall.
I am not sure I told this back story before... KJRR may determine I told this in another post, but here goes.
I was was asked by my Executive Engineer to develop a 2.0L Ranger as an entry leader vehicle. Using the venerable 2.3L destroked to 2.0L. I did not really want to do this but I needed a paycheck and believed in following my superior's direction. So this 2.0L would have a progressive two barrel carburetor from Asien in Japan. Asien would send an engineer to do the carburetor tuning and the emissions system. An accelerated program. Early development went relatively smoothly and then we headed to cold weather development...This was where we hit major problems. As we headed North out of Dearborn toward our Minnisota test facility in Bemidji MN the trucks, three of these prototypes, we hit drivablility problems and loss of power to the point we would be stranded on the side of the road in sub 0° temps. WTF????? Engines would idle roughly but no power. Pop the hood and look for a possible cause. None of the other engineers, two other engineers including the Japanese engineers could figure this. So I took this approach...what is new to this engine from the 2.3l...Well the Carburetor was one and then there was this EGR transducer (Exhaust Gas Recirculation). I turned to the other folks and told them that the engine was choking on its own exhaust via the EGR system being wide open. I took one of the transduces out of the engine and put it under my coat...it was frozen but my body heat thawed it out after a while and we reinstalled it on the motor and the performance returned...So we had an EGR Transducer icing problem and about 500 miles to go to get to Bemidji. How do we do this? So I hit upon visiting McDonnolds, Burger King etc. We would drive in to the fast food emporium, pull the transducers and plead with the counter help to put them under a heat lamp to thaw them out....then shake the water out of them and reinstall. We usually bought coffee and one Tea... So that is how we made Bemidji MN, by driving between fast food restaurants...
Call back to Japan after this resulted in a total redesign of the EGR system for the 2.0L...
Quite a nightmare in freezing cold...
best,
Phil
