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.
