Hi Arriane. I think EGR's first appeared on petrol engines in 1973.

I'm not sure diesel engines are more complex. They didn't used to be regarded as such due to the lack of an ignition system. True they have gained an EGR but petrol engines already had that. The only thing I can think of that petrol engines don't have is the DPF, but against the complexity of the petrol's ignition system seems to me the petrol is still more complex. Diesel's were regarded as being more robust due to the need to cope with higher combustion pressures.

I think the only real way to get a less complex engine is to buy a classic car pre 1973. 245's are pretty simple really. The exhaust stinks though.
