Hello
I have been seeking information
on the 160 hp Bolinder semi-diesel available in 1916. It was
used in an Arctic vessel, the
Great Bear, and I would like to know its fuel consumption. Do
you know or could you advise me whom to ask?
Thank you. Paul Spitzer

To Paul Spitzer.
The Great Bear
was a schooner. It's name appears in a book published by
Bolinder's in about 1915. Sadly, there is no picture of this
particular vessel although there are many others, including the
Yavari.
Fuel consumption,
according to Walter Pollock's "Hot Bulb Engines and Suitable
Vessels", published 1919,
" An average
consumption for an engine above 100 B.H.P., is about 0.55 lb per
B.H.P.per hour, using a good cheap fuel of a specific gravity
rather under 0.9, such as gasoleum and similar fuels mentioned
in Chapter V. ( I could provide this if required) When running
light the total consumption per hour is never likely to exceed,
say, one-fifth of the full load figure.
When running
light an engine will burn about 5% less fuel when governing by
the fuel pump stroke than when the stroke remains full and the
governing is solely by " hit-and-miss."
Again, engines
fitted with means of throttling the scavenge air effect a
further saving of some 10% in the fuel consumption when running
light."
The Marine Oil
Engine Handbook gives a figure of 0.547lb per B.H.P. hour.
Query 010
To Dr Davide
Gnola.
Pollock's "The
Bolinder Book", published 1930, foresaw engines being produced
in Italy " in the not far-distant future". The Agent in Italy at
that time was;
Bolinder's S.A.
Italiana,
99, Via Vittorio
Venito, Roma. I do not have any literature on these engines.

Can someone
help please ???? what size thread is the oil gauge take off
connection on the side of the block of our Bolinder 1052 ,it looks
like 1/8" B.S.P. I don't want to undo it until I'm sure, (I'm
going to put an oil pressure gauge out side next to the steering
wheel) cheers

Oil
Pressure Take-Off Adapter
I have removed the oil take off
adapter from Bolinder 1001 it measures 9.7mm and has 28 threads per
inch. According to
http://www.fullermetric.com/Dimensional_Information/ThreadIDBritish.htm
this would make it 3/8” British
Standard Pipe (BSP)
