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 |

i might add @technicalninja
there is very little written about the history of Ljet and its development. even by bosch themselves. its possible texts exist in german and are held in technical universities in germany. but i have not found anything in searches. i don't even know who the main mind behind it was. but its a classic bit of avant garde modernist thinking. its called inversion. you rigorously observe the opposite principle. you force yourself to think the opposite way from the way it is. thats basically what they did. thought of it as the opposite of D jet. thats a very smart way to go about things. regarding australia and lumping it in with the rest of the world. very american attitude. no offense taken. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) post WW2 australia is riven politically and economically by two tensions. the establishment tied to the british upper ruling class and the aftermath of its origins as a colony and their interests in the "mother" country. and a new emergent group allied to the United States and its vision for the pacific post WW2. despite the awfulness of WW2 and the aftermath of the Japanese being the enemy Australia was one of the first countries to really open itself culturally and economically wit Japan. we supplied them with iron ore etc etc. we got all their cars before you guys. we were the guinea pigs for the japanese export car market. it all came here and got tried out before it was sent in big numbers to you guys. i believe some of the earliest datsun 240Zs ever made came to australia before they even hit the domestic J market. it helps to be right hand drive when it comes to japanese product. secondly a massive immigrant population post WW2 of greeks, italians, germans. lithuanians, russian jews. you name it fostered the import industry of european cars. alfas, fiats, lancias, VWs, Porsche, Mercs, Citroens, Panhards, on and on. the only carmakers to suffer defeat were you guessed it. the mother countries rolling junk piles. morris, austin, shaguars, etc. |
