What drivers used to know - lean jolting
12/20/2019
In the past, especially in the seventies and eighties, you often read about it in test reports. There was talk of "lean-burn". What was meant was a consumption-optimized tuning (lots of air, little fuel) of the carburettor, which led to a jerking of the vehicle when accelerating, i.e. could not ensure continuous traction.
Drivers then compensated for the jerking by pulling the choke, which made the mixture richer. And yes, of course, modern drivers no longer know the "choke" either.
With electronically controlled injection systems, the lean-burn phenomenon later disappeared to a large extent, although even today you still sometimes get the opposite impression, especially in winter and during the warm-up phase. Nevertheless, hardly anyone talks about "lean-burn" today.
