Willys Jeep Truck
The Willys Jeep Truck is a truck made by Willys-Overland Motors from 1947 to 1965. The styling and engineering of the Jeep Truck was based on Willys' existing vehicles, the Willys Jeep Station Wagon and the Jeep CJ-2A. Production The Jeep Truck was introduced in 1947 as a 1-ton four-wheel drive truck with a wheelbase of . It was available as a pickup truck, a platform stake truck, a chassis cab, or a bare chassis. A ¾-ton two-wheel drive version became available by 1949. The truck was restyled in 1950 with the addition of a V-shaped grille with five horizontal bars. In 1951 the ''Hurricane'' IOE four cylinder engine replaced the earlier flathead engine, increasing power from to . Optional accessories included an engine governor, a power takeoff, and a pulley drive. A "Dump-O-Matic" hydraulic hoist became available for 1957. Over 200,000 of these trucks were manufactured. Models Drivetrain The Jeep Truck was available with only one transmission, the Borg-Warner T- ...

Willys
Willys (pronounced , "Willis" ) was a brand name used by Willys–Overland Motors, an American automobile company, founded by John North Willys. It was best known for its design and production of World War II era and later military jeeps (MBs), as well as civilian versions (Jeep CJs), and branding the 'jeep' military slang-word into the '(Universal) Jeep' marque. History Early history In 1908, John Willys bought the Overland Automotive Division of Standard Wheel Company and in 1912 renamed it Willys–Overland Motor Company. From 1912 to 1918, Willys was the second-largest producer of automobiles in the United States after Ford Motor Company. In 1913, Willys acquired a license to build Charles Yale Knight's sleeve-valve engine which it used in cars bearing the Willys–Knight nameplate. In the mid-1920s, Willys also acquired the F.B. Stearns Company of Cleveland and assumed continued production of the Stearns-Knight luxury car, as well. John Willys acquired the ...

Straight-six Engine
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 75 ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ...

Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though so ...

Continental Motors Company
Continental Motors Company was an American manufacturer of internal combustion engines. The company produced engines as a supplier to many independent manufacturers of automobiles, tractors, trucks, and stationary equipment (such as pumps, generators, and industrial machinery drives) from the 1900s through the 1960s. Continental Motors also produced automobiles in 1932–1933 under the name Continental Automobile Company. The Continental Aircraft Engine Company was formed in 1929 to develop and produce its aircraft engines, and would become the core business of Continental Motors, Inc. Company history In 1905, Continental Motors was born with the introduction of a four-cylinder, four stroke cycle L-head engine operated by a single camshaft. In August 1929, the Continental Motors Company formed the Continental Aircraft Engine Company as a subsidiary to develop and produce its aircraft engines. Continental Motors entered into the production of automobiles rather indirect ...

Power Take-off
A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine. Most commonly, it is a splined drive shaft installed on a tractor or truck allowing implements with mating fittings to be powered directly by the engine. Semi-permanently mounted power take-offs can also be found on industrial and marine engines. These applications typically use a drive shaft and bolted joint to transmit power to a secondary implement or accessory. In the case of a marine application, such shafts may be used to power fire pumps. In aircraft applications, such an accessory drive may be used in conjunction with a constant speed drive. Jet aircraft have four types of PTO units: internal gearbox, external gearbox, radial drive shaft, and bleed air, which are used to power engine accessories. In some cases, aircraft power take-off systems also prov ...

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced so ...

IOE Engine
The intake/inlet over exhaust, or "IOE" engine, known in the US as F-head, is a four-stroke internal combustion engine whose valvetrain comprises OHV inlet valves within the cylinder head and exhaust side-valves within the engine block.V.A.W Hillier: ''Fundamentals of Motor Vehicle Technology'', 4th edition, Standly Thornes, Cheltenham 1991, , p. 39+40 IOE engines were widely used in early motorcycles, initially with the inlet valve being operated by engine suction instead of a cam-activated valvetrain. When the suction-operated inlet valves reached their limits as engine speeds increased, the manufacturers modified the designs by adding a mechanical valvetrain for the inlet valve. A few automobile manufacturers, including Willys, Rolls-Royce and Humber also made IOE engines for both cars and military vehicles. Rover manufactured inline four and six cylinder engines with a particularly efficient version of the IOE induction system. A few designs with the reverse system, exhaust ...

Rolling Chassis
A rolling chassis is the chassis without bodywork of a motor vehicle ( car, truck, bus, or other vehicle), assembled with suspension and wheels. Heavy vehicles Separate chassis remain in use for almost all heavy vehicles ranging from pickup trucks to the biggest trucks and commercial passenger carrying vehicles. The rolling chassis is delivered to the commercial body maker, coachbuilder, or bulk transporter on its own wheels, under its own power. Automobiles Rolling chassis was a stage of manufacture of every vehicle. Mass produced cars were supplied complete from the factory, but luxury cars like Rolls-Royce were supplied as a chassis from the factory to several bespoke coachbuilders like J Gurney Nutting & Co who would supply a body to the customer's order (or build a car which was sold from their showroom). Automobile construction methods changed when unibody A vehicle frame, also historically known as its '' chassis'', is the main supporting structure of a ...

Chassis Cab
A chassis cab, also called a cab chassis or half truck, is a type of vehicle construction, often found in medium duty truck commercial vehicles. Instead of supplying the customer with a factory pre-assembled flatbed, cargo container, or other equipment, the customer is given the vehicle with just chassis rails and a cab. This allows the customer to add any desired aftermarket equipment, such as fire apparatus, ambulance, or a recreational vehicle conversion package, which can be customized for the specific needs of the customer. Cutaway van chassis are similar vehicles, but have specific components at the rear whereas chassis cabs usually do not have additional components. Vehicles of this type are produced by Ford, Chevrolet/ GMC, and Ram Trucks Ram Trucks, stylized as RAM and formerly known as the Ram Truck Division (of Chrysler), is an American brand of light to mid-weight trucks and other commercial vehicles, and a division of Stellantis (previously Fiat Chrysler A ...
