Totally, and everytime one of those is replaced with a new one our air gets better. Related - there are a ton of old Detroit 2 cycle diesel motors on heavy trucks that are being phased out. Its getting harder to find mechanics to work on them. Super interesting motor if your interested in that kind of stuff, 2 cycle diesel, very reliable, highly polluting.
