Default Detroit Diesel Knock offs

I remember in the late 70s seeing a knock off of the two cycle 71 series Detroit. I can`t remember the manufactures name or where they were made. Japan? China? They were a pair of marine engines and identified as 8V-75s They were two cycle with a blower but had a external high pressure fuel injection pump instead of unit injectors. I also remember seeing a brochure with the same model identifications as the Detroit. 3,4,6,V6,and V8-75s. I have searched the web and come up empty. Has anyone heard about or seen any of these engines? AL

Al, I know exactly what you are talking about. A friend in Oz has several of them, he calls them "Hiroshima Screamers". They were built by Nissan and labeled as UD Diesels. They were imported into the United States by Chrysler. This same friend has a Russian knockoff of a 4-71 which is very interesting. I will email you some more pictures of them.

Germany had an
eng, that looked like a Detroit before Detroit was around, it was upside down oil was pump to a pan overhead and dripped fed down to the eng. I saw it 40 years ago and the man that had it said it came out of a 1930 U boat. Looked a lot like a Detroit

I was told that the Russians liked the Detroit 12-V71 and made a two stroke knock off model. They supposedly could not manufacture a reliable crankshaft for it and used a genuine Detroit crank in it instead. They got them off the black market. Heard this account from my instructor at the factory 53-71 engine class in the late 60s. True or not it makes a good story. AL
