A 6 h.p. engine at full load required 62 litres of acetylene
carburetted with 197 grammes of petroleum spirit per horse-power-hour
(uncorrected); while a similar motor fed with low-grade Taylor fuel-gas
took 1260 litres per horse-power-hour, but on an average developed the
same amount of power from 73 litres when 10 per cent. of acetylene was
added to the gas. Lepinay found that with pure acetylene ignition of the
charge was apt to be premature; and that while the consumption of
carburetted acetylene in small motors still materially exceeded the
theoretical, further economics could be attained, which, coupled with the
smooth and regular running of an engine fed with the carburetted gas,
made carburetted acetylene distinctly the better power-gas of the two.
CHAPTER XI
COMPRESSED AND DISSOLVED ACETYLENE--MIXTURES WITH OTHER GASES
In all that was said in Chapters II., III., IV., and V. respecting the
generation and employment of acetylene, it was assumed that the gas would
be produced by the interaction of calcium carbide and water, either by
the consumer himself, or in some central station delivering the acetylene
throughout a neighbourhood in mains.
