The Gunderson Do-All Machine is a colorful, interconnected network of dozens of machines that have been cross-sectioned to reveal their internal operating mechanisms. It was designed by Mark Gunderson to illustrate mechanical concepts.
The Gunderson Do-All Machine includes more than 30 individual machines that are linked together by an array of belts, gears, pulleys, and transmissions. Collectively, they operate in a continuous chain reaction on the power of one 10-horsepower (7.5 kW) Whitte gas oil well engine, forming a kinetic sculpture. The entire network is mounted on a 15-foot (4.6 m) flat bed trailer platform, so that it can be transported to engine shows, educational venues, and county fairs. The combined weight of the trailer and all components is about 6000 pounds.
The Do-All's layout and design allows one to follow the chain reaction from machine to machine while observing the internal cogs, gears, and other components that make them work. The variety of machines include an automatically reversing worm gear, a water pump impellar, a governor/gas valve from a 20-horsepower (HP) JC engine, a blacksmith blower/bubble maker, the main line shaft and pulley from an antique corn grinder, a floating gear, a DC 110-volt generator and lights, a 38-to-1 gear reducer, a bicycle light generator, and a fan blower painted to look like a clown. Recent additions include a penny press that creates a commemorative Do-All Machine coin and a rotating satellite dish with sun and moon images painted on opposite sides.
The Gunderson Do-All includes the following major engines that have been cut away to reveal their inner workings in action:
Felix Heinrich Wankel was a German mechanical engineer and inventor after whom the Wankel engine was named.
The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing around a fixed-toothed gearing. The midpoint of the rotor moves in a circle around the output shaft, rotating the shaft via a cam.
The Mazda RX-7 is a front-engine, rear-wheel-drive, rotary engine-powered sports car that was manufactured and marketed by Mazda from 1978 until 2002 across three generations, all of which made use of a compact, lightweight Wankel rotary engine.
The Mazda RX-8 is a sports car manufactured by Japanese automobile manufacturer Mazda between 2003 and 2012. It was first shown in 2001 at the North American International Auto Show. It is the direct successor to the RX-7. Like its predecessors in the RX range, it is powered by a rotary Wankel engine. The RX-8 was available for the 2003 model year in most parts of the world.
The Mazda Cosmo is an automobile which was produced by Mazda from 1967 until 1996. Throughout its history, the Cosmo served as a "halo" vehicle for Mazda, with the first Cosmo successfully launching the Mazda Wankel engine. The final generation of Cosmo served as Mazda's flagship vehicle in Japan, being sold as the Eunos Cosmo through its luxury Eunos division in Japan.
The Mazda Luce is an executive car that was produced by Mazda in Japan from 1966 until 1991. It was widely exported as the Mazda 929 from 1973 to 1991 as Mazda's largest sedan. Later generations were installed with luxury items and interiors as the Luce became the flagship offering. The Luce was replaced by the Sentia in 1991 which was also exported under the 929 nameplate.
Redline refers to the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine. The redline of an engine depends on various factors such as stroke, mass of the components, displacement, composition of components, and balance of components.
The Mazda Wankel engines are a family of Wankel rotary combustion car engines produced by Mazda.
The Mazda 787 and its derivative 787B are Group C sports prototype racing cars that were developed by Japanese automobile manufacturer Mazda for use in the World Sportscar Championship, All Japan Sports Prototype Championship, and the 24 Hours of Le Mans from 1990 to 1991. Designed to combine a mixture of the Fédération Internationale du Sport Automobile (FISA) Group C regulations with the International Motor Sports Association (IMSA) GTP regulations, the 787s were the last Wankel rotary-powered racing cars to compete in the World and Japanese championships, using Mazda's R26B engine.
A horse engine is a machine for using draft horses to power other machinery. It is a type of animal engine that was very common before internal combustion engines and electrification. A common design for the horse engine was a large treadmill on which one or more horses walked. The surface of the treadmill was made of wooden slats linked like a chain. Rotary motion from the treadmill was first passed to a planetary gear system, and then to a shaft or pulley that could be coupled to another machine. Such powers were called tread powers, railway powers, or endless-chain powers. Another common design was the horse wheel or sweep power, in which one or several horses walked in a circle, turning a shaft at the center. Mills driven by horse powers were called horse mills. Horse engines were often portable so that they could be attached to whichever implement they were needed for at the time. Others were built into horse-engine houses.
Hydrogen technologies are technologies that relate to the production and use of hydrogen as a part hydrogen economy. Hydrogen technologies are applicable for many uses.
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power.
The following outline is provided as an overview of and topical guide to machines:
Max Bentele was a German-born pioneer in the field of jet aircraft turbines and mechanical engineering. His contributions to the development of the Wankel engine earned him the title, "Father of the Wankel Engine in the United States".
The Mazda Furai was a concept car revealed on 27 December 2007 and designed by Swift Engineering and manufactured by Mazda. A teaser image of the vehicle was released on 11 December 2007. The Furai officially debuted at the 2008 North American International Auto Show in Detroit.
The Mazda RX-01 was a concept car produced by Mazda that debuted at the 1995 Tokyo Motor Show.
Kenichi Yamamoto was a Japanese mechanical engineer and business executive. He supervised the development of the Mazda Wankel rotary combustion engine, and served as Mazda's President (1984–1987) and Chairman (1987–1992).
The Mazda HR-X was the first hydrogen powered concept car produced by Mazda. The car was unveiled at the Tokyo Motor Show in 1991. The car seated four people in a plastic shell and was powered by a two rotor Wankel engine which propelled it to 130 km/h (81 mph). The hydrogen was stored in a cooled metal hydride tank and 3.32 kilograms (7.3 lb) provided a range of 190 km (120 mi). It was the first in a series of demonstration hydrogen internal combustion engine vehicles produced by Mazda.
The Mazda MX-30 is a subcompact crossover SUV produced by Mazda and sold as a battery electric (BEV), plug-in hybrid (PHEV) or mild hybrid (MHEV) variant. Based on the CX-30, it was unveiled at the 2019 Tokyo Motor Show. Production of the vehicle, which is Mazda's first mass-produced electric car, began at their Ujina factory on 19 May 2020.
