A Place For Fun With Old Engines
This subject is from the 1940s...
PRESENTING THE
Enterprise was a long time builder of marine diesel
engines located in California. The company dated back to 1866.
In addition to the two manufacturing facilities located near San
Francisco, the company also had sales offices on the Atlantic,
Gulf, and Pacific coasts and on inland waterways. Enterprise was
well known for their very heavily constructed four-stroke cycle
diesels that had operating speeds on the lower end of the medium
speed range.
The turbocharged versions of the engines used the
Buschi system of compounding impulses of exhaust gas. This arrangement,
and the general design of the Enterprise engines, had considerable
similarities to the ALCO M&S engines that were built in comparable
sizes and also used the Buschi system. The Enterprise engines
were arranged so that in marine applications the turbocharger
could be mounted on either end of the engine for layout convenience.
Enterprise was a very active diesel builder throughout
World War Two and made substantial improvements in their plants
in the late 1940s in anticipation of an expanding diesel market.
The engine series and illustrations shown here would be applicable
to the company's late 1940s product line.
**********
Above: The Enterprise DMX series engines were
heavily constructed medium speed four-stroke cycle diesels with
10-1/2 inch bore and 12 inch stroke. This series was built in
a normally aspirated version with ratings up to 375 horsepower
at 600 RPM, and in a turbocharged version with available ratings
up to 565 horsepower at 600 RPM.
**********
Above: The Enterprise DMG series four-stroke cycle
diesels were built in both six cylinder and eight cylinder versions,
all with 12 inch bore and 15 inch stroke. The normally aspirated
six cylinder engine had ratings up to 615 horsepower, the eight
cylinder engine was rated up to 820 horsepower, both at 600 RPM.
The turbocharged versions of the engine had ratings of 925 horsepower
for the six cylinder engine, and 1230 horsepower for the eight
cylinder, both at 600 RPM.
**********
Above: The Enterprise DMQ series were four stroke
cycle diesels with 16 inch bore and 20 inch stroke, and were built
in six cylinder and eight cylinder versions. The normally aspirated
six cylinder was rated up to 875 horsepower, the normally aspirated
eight cylinder at 1170 horsepower, both at 360 RPM. The turbocharged
versions of the engine produced 1315 horsepower from six cylinders
and 1755 horsepower from eight cylinders, both at 360 RPM.

The Enterprise manufacturing facilities were located
in San Francisco and South San Francisco California.
