Detroit Diesel 8V-71T as used in the U.S. M109 self-propelled howitzer. Bore and stroke are the same across all units, at 4 + 1 ⁄ 4 in × 5 in (108 mm × 127 mm). Inline models were famously "symmetrical," meaning that the blower, exhaust, water manifold, starter, and other components could be mounted on either side of the basic block to fit ...
For this reason the motor-mower (essentially an engine-driven, walk-behind sickle-bar mower) model 243 was created. This was among the first self-propelled motor-mowers in the world. At the end of the 1960s BCS entered into a technology-sharing venture with the Grillo company of Italy, the goal being to integrate soil-working implements into ...
Allis-Chalmers was a U.S. manufacturer of machinery for various industries.Its business lines included agricultural equipment, construction equipment, power generation and power transmission equipment, and machinery for use in industrial settings such as factories, flour mills, sawmills, textile mills, steel mills, refineries, mines, and ore mills.
Smaller mowers often lack any form of self-propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" types or, more often, are "ride-on" mowers that the operator can sit on and control.
[12] [13] [14] A Van Duzen single-cylinder gasoline engine was mounted on a Robinson engine chassis, which could be controlled and propelled by Froelich's gear box. [15] After receiving a patent, Froelich started up the Waterloo Gasoline Engine Company and invested all of his assets. The venture was very unsuccessful, and by 1895 all was lost ...
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.

The simplest inlet to a centrifugal compressor is typically a simple pipe. Depending upon its use/application inlets can be very complex. They may include other components such as an inlet throttle valve, a shrouded port, an annular duct (see Figure 1.1), a bifurcated duct, stationary guide vanes/airfoils used to straight or swirl flow (see Figure 1.1), movable guide vanes (used to vary pre ...
