Has there ever been a reason Porsche/VW speced L-jet injection for the 1.8 engines instead of D-jet like the 1.7 and 2.0 engines used?
Usually when manufactures do this there are financial reasons for the change. Either they have the same engine on other vehicles they produce, or its just cheaper to use whatever part is being used. But Porsche didn't use the T4 motor on other cars at the time. And if it was cheaper, they would have done away with Djet on the 1.7 and 2.0. I don't think VW was using l-let at the time for the bus... but maybe? There has to be a reason that Porsche wanted Ljet on the 1.8. Zach |

The early use of CDI ignition was single strike (most of them) and was employed to increase ignition power at higher RPM. The baby coils we had back then suffered bigtime power loss above 5K rpm.
I have a funny story about cascading capacitors... My wife, who loves to take pictures had an "all in one" 35mm film camera (compact) that the "on" button stopped clicking and the camera would not open. Felt like a mechanical switch malfunction. We upgraded to digital, and the old camera sat for 6+ months (no film or 2 double A batteries in it). I mess with shit... So, I figured out how to get the "Chinese finger puzzle" case off of it and started "playing". I was messing with the on button and got into the circuitry for the flash. GAARRRZAP! It knocked me clean off the bar stool I was sitting on... Bit me HARD! My brain screamed Capacitor! OK, it's discharged now... I'm SAFE! Nope! Again, it knocks me off the stool! CASCADING CAPICITORS!!!! Now, I'm pretty gun shy about this camera... The THIRD time it knocks my dick in the dirt I take it over to the round file and trash that critter. 3 volts, no voltage for 6 months, and it still had the ability to light my fire at LEAST three times... I KNOW where the personal stun guns came from. I WILL NOT pick up a flash capable camera that has fallen into water with bare hands ever again... |
