1976 Is it a 49 state or Cali car? Options

[gnomefabtech]

Car came from Nevada but I can't tell if it was originally a California car. It still has injection but doesn't have a cat or smog pump. Doesn't look like it ever had either but I'm wondering since I'm going to try and register it here in California. Thanks in advance!!

Here is the Vin:

All car still have the function of the secondary air injection. It was first handled by an actual belt driven pump. Many cars changed over to electrically driven pumps like the mentioned Toyotas and many more.

Modern cars just use the engine itself. One cylinder doesn't get fuel or fire for one cycle and 500cc of secondary air enters the airstream. You cannot feel this when it happens, and it happens far more often than you might imagine.

The EGR function is now handled by intentional cam profile overlap. Putting more duration into a cam requires a higher static compression ratio which further helps efficiencies. It's not just VVT stuff. It's everything now. The only new cars that currently have EGR valves are all diesels and those vehicles didn't get EGRs until 2007 when the diesel emission laws went ballistic.

New cars have tailpipe emissions so clean from the combustion chamber that the cats don't have to work nearly as hard as they did in the past. They "light off" faster and can live 200K miles now.

I will say the new M20A-FKS/FXS 2.0L and A25A-FKS/FXS 2.5L 4 cylinder Toyota gasoline/hybrid engines now have EGR valves and EGR coolers now as of 2018 to current model year equipped vehicles. As it's not just diesels these days.
