When I started in the fuels and lubes research business in 1967, a big part of my job was to monitor changes in automotive technology and the effect that these changes had on the fuels and lubricant requirements.
I remember the first emission control engines and their effect on temperature and operating conditions. I followed the technology through VW’s electronic fuel injection to electronic ignition, EGR, catalytic converters, and on and on.
The new technology worked very well, except for a few initial problems like when one of the manufacturers used aluminum connectors in its electronic ignition circuits. Just a small amount of corrosion increased the resistance and the engines died. But these gremlins were worked out and the new systems work very well.[Read more…]
