I had an early version of a Volvo 245 - a 1975, which had a 240 body and a B20 engine, with the same K-Jet that ran in the 140s. The K-Jet without a Lambda Emissions control system.
The add-on that Phil described - the Lambda Sond Emissions Control, with a CAT as part of the exhaust, came in with the B21 engine.
The first 240s with B21s did not have Lambda systems or CATS. 77-78 I think was the transition to that emission control system.
The K-Jet is, as noted entirely mechanical---and was a welcome replacement to Carburators.
Used in BMW and Porsche... too.
