All B series engines are 4 cylinder, 4 cycle diesel engines. Most were manufactured by Hino
Industries, a sub-contractor of Toyota. Some were manufactured by Daihatsu, identified by the letter
"D" on the timing cover. Apparently Hino engines similar to the B and 3B are used to run the
refrigeration units on some tractor-trailers. Most diesels in Japan and Canada are 24V (and
therefore meet NATO military specs), with the exception of Canadian BJ60s and 1985 BJ70s which
are 12V. In Europe, all diesels before 1984 are 24V, and most B series after 1984 are 24V as well.
Australian diesels are 12V.
