If you read this series of 4 articles about Chevron oil development along with the changes in emission controls on diesel truck engines, you can get a grip on how advanced the modern engines are over their 1980 cousins.
The new engines have about 5% of the pollution of a typical 1980 engine. So little exhaust soot, that the tailpipes might start to rust on the inside!
The injection pressures in the 60's and 70's was around 3,500 PSI, and timing took a while to inject the proper amount of fuel per injection. Todays fuel injectors have 35,000 PSI and can shorten the time it takes to inject the fuel, or even give a pre-squirt then full fuel squirt on each top dead center of the engine.
