Good afternoon,
in the french Messageries , we had in the early 30's , two mix cargo vessels ( the OREGON and the SAGITTAIRE ) built in 1929 in Germany ; they were fitted each with two two cycle , double acting , 5 cylinders , blast injection MAN engine , directely reversible .They were scrapped in the late 50's .As some informations strawed from the magazines and periodics of the company , both ships had always troubles with driven injectors needles of their atomisers ( quite fragile ) , but not from their 3 stages , engine driven compressor .they ( of course à suffered ) a lot fron the piston rods that had tendencies to bend .All the history of these ship have , most of the time , at least one line saying : " left Marseille harbor , but had to come back 4 hours later due to engine trouble "( ....) .And this frm 1930 up to 1955...
Also , some ww1 subs still in use in the French navy , in 1940 , ere powered with medium speed 2 stroke Sulzer engines , with blast injection ( an air compressor was driven by the engine , as well as the scavening pump) ; and in some books , one can read " resetting of the injection needle vaves " or " had to stop std engine to fix leaks on the compressor high pressure valves ".
some photos are available on the net , if you use polymeta , and write " blast injections engines "
i know also that B and W used this for their 4 stroke , double acting , 10 cylinders , twin engines fitted in 1927 on the ship GRIMPSHOLM .But i got no infos about it , except that in the engineering galeery here , one pic of it exist .
