This is a Hall Scott Model 177 engine. It has a displacement of 855 cubic inches with a 5-1/2” bore and a 6” stroke. It produces 245 horsepower at 1600 revolutions per minute and 900 foot-pounds of torque at 1200 revolutions per minute.

This is a cutaway of a White Model 250A truck engine. This 150-horsepower gasoline engine was introduced to the heavy truck market in 1940. This engine featured a number of innovations for its time. It reduced weight per horsepower by 35% and increased horsepower per cubic inch of displacement by 20%, increased miles per gallon and decreased fuel cost by almost 20%, increased the safe governed speed from 2400 to 3000 revolutions per minute, and introduced sodium-cooled exhaust valves, zero-lash hydraulic valve lifters, stellite-faced valve seats and the use of dry ice for shrink-fitting them, the two-barrel carburetor, and the first bypass thermostat cooling system for quick warm-up with water flowing freely.

This cutaway has been color-coded to help show what would be in each part of the engine: yellow is oil, dark blue is water, red is exhaust, green is intake gas, and light blue is intake air. This cutaway was created around 1960 at the University of Portland.

This Cummins HRS200 engine has a displacement of 743 cubic inches and produces 225 horsepower at 1800 revolutions per minute. It was originally used in the Lochausen’s 1946 Kenworth Model 523 Tractor #9, which is also here in the museum, having been equipped with a 220-horsepower Cummins NH220 engine in 1985.

IMG_5105 Detroit Diesel Allison GT404 Turbine Engine at Antique Powerland in Brooks, Oregon on July 31, 2010
Detroit Diesel Allison GT404 Gas Turbine on July 31, 2010

This is a Detroit Diesel Allison GT404 Gas Turbine Engine. Allison’s development of gas turbine engines was derived from the General Electric J31 engines used to power the Bell P-59 Airacomet, the first American fighter jet. After World War II, Detroit Diesel Allison went on to develop the Model 501 turboprop which powered the Lockheed C-130 cargo plane, and was adapted for generator sets, pumps, compressors, oil field and marine equipment. Detroit Diesel Allison also developed the 250 Series turbines to power light helicopters and fixed-wing aircraft. In the 1970s, Detroit Diesel Allison promoted the GT404 and GT505 gas turbine engines for use in highway trucks, scrapers and crawler tractors, generator sets, bulk unloaders, air compressors, motor coaches, pleasure boats, work boats and tug boats. Advantages of the GT404 and GT505 cited by Detroit Diesel Allison included clean exhaust, serviceability, smooth power with high torque rise, effective engine-dynamic braking, simplified transmission requirements, superior cold weather starting, light weight and a simple cooling system. Despite a variety of applications of the gas turbine engines, they fell from favor due to rising fuel costs, although Allison continued turbine development into the early 1990s.
