Honda PC50
The Honda PC50 is a moped produced by the Honda Motor Company in Japan from May 1969 until February 1977. The PC50, though much smaller and lighter, had some similar features to Honda's popular C50 /70 /90 Super Cub line, with a step-through pressed-steel frame, a fuel tank under the saddle, a chain cover, and optionally equipped with leg shields, Construction Engine A distinctive feature of the PC50 is the use of a four-stroke engine, at a time almost all pedal-equipped mopeds used two-stroke engines. Honda's early development of 50 cc four-stroke engines was a result of Soichiro Honda's dislike of the sharp noise of two-stroke engines. The PC50 used two different engines during its production. The first models featured an overhead camshaft (OHC) engine derived from the Honda P50 moped which used an engine in wheel arrangement. The OHC engine was used from start of PC50 production until April 1970 when the OHC engine gave way to the OHV (pushrod) engine in the same cycle fram ...

Honda Super Cub
The Honda Super Cub or Honda Cub is a Honda underbone motorcycle with a four-stroke single-cylinder engine ranging in displacement from . In continuous manufacture since 1958 with production surpassing 60 million in 2008, 87 million in 2014, and 100 million in 2017, the Super Cub is the most produced motor vehicle in history. Variants include the C100, C50, C70, C90, C100EX and C70 Passport, as well as the Honda Trail series. The Super Cub's US advertising campaign, ''You meet the nicest people on a Honda'', had a lasting impact on Honda's image and on American attitudes to motorcycling, and is often used as a marketing case study. Development The idea for a new motorcycle was conceived in 1956 when Honda Motor's Soichiro Honda and Takeo Fujisawa toured Germany and witnessed the popularity of mopeds and lightweight motorcycles. Soichiro Honda was primarily the engineering and production leader of the company, always with an eye towards winning on the racetrack, while his close ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Telescopic Fork
A telescopic fork is a form of motorcycle front suspension whose use is so common that it is virtually universal. The telescopic fork uses fork tubes and sliders which contain the springs and dampers. The main advantages of the telescopic fork are that (i) it is simple in design and relatively cheap to manufacture and assemble; (ii) it is lighter than older designs using external components and linkage systems; and (iii) it has a clean and simple appearance that bikers find attractive. Telescopic forks sometimes have gaiters to protect the fork tubes from abrasion and corrosion. A more modern (and more expensive) version of the conventional telescopic fork is the inverted or "USD" (upside-down) fork. BMW's patented telelever front suspension appears at first glance to be conventional telescopic fork, but the fork tubes contain neither springs nor damping. Instead, a wishbone and an inboard monoshock perform suspension duties, and the forks serve to locate the front wheel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Splash Lubrication
Splash lubrication is a rudimentary form of lubrication found in early engines. Such engines could be external combustion engines (such as stationary steam engines), or internal combustion engines (such as petrol, diesel or paraffin engines). Description An engine that uses splash lubrication requires neither oil pump nor oil filter. Splash lubrication is an antique system whereby scoops on the big-ends of the connecting rods dip into the oil sump and splash the lubricant upwards towards the cylinders, creating an oil mist which settles into droplets. The oil droplets then pass through drillings to the bearings and thereby lubricate the moving parts. Provided that the bearing is a ball bearing or a roller bearing, splash lubrication would usually be sufficient; however, plain bearings typically need a pressure feed to maintain the oil film, loss of which leads to overheating and seizure. The splash lubrication system has simplicity, reliability, and cheapness within its v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soichiro Honda
was a Japanese engineer and industrialist. In 1948, he established Honda Motor Co., Ltd. and oversaw its expansion from a wooden shack manufacturing bicycle motors to a multinational automobile and motorcycle manufacturer. Early years Honda was born in Kōmyō village, Iwata District, Shizuoka, near Hamamatsu on November 17, 1906. He spent his early childhood helping his father, Gihei Honda, a blacksmith, with his bicycle repair business. At the time his mother, Mika Honda, was a weaver. Honda was not interested in traditional education. His school handed grade reports to the children, but required that they be returned stamped with the family seal, to make sure that a parent had seen it. Honda created a stamp to forge his family seal out of a used rubber bicycle pedal cover. The fraud was soon discovered when he started to make forged stamps for other children. Honda was unaware that the stamp was supposed to be mirror-imaged. His family name 本田 (Honda) is symmetrical when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Honda P50
The Honda P50 (known as the P25 in some markets) was introduced in June 1966. It was the last motor-wheel moped design by Honda (and probably by any other large manufacturer). The P50 features a step-through frame made from steel pressings, leading-link front suspension, plastic fenders and chainguard. The fuel tank is located above the rear fender, and the key distinguishing feature of the design is the engine being located at the extreme lower left rear of the frame, with all of the driveline components housed within the large hub of the rear wheel. The engine is also 4-stroke — unusual when almost all pedal-equipped mopeds used simpler 2-strokes. Soichiro Honda was a Japanese engineer and industrialist. In 1948, he established Honda Motor Co., Ltd. and oversaw its expansion from a wooden shack manufacturing bicycle motors to a multinational automobile and motorcycle manufacturer.

Moped
A moped ( ) is a type of small motorcycle, generally having a less stringent licensing requirement than full motorcycles or automobiles. The term used to mean a similar vehicle except with both bicycle pedals and a motorcycle engine. Mopeds typically travel only a bit faster than bicycles on public roads. Mopeds are distinguished from motor scooters in that the latter tend to be more powerful and subject to more regulation. Some mopeds have a step-through frame design, while others have motorcycle frame designs, including a backbone and a raised fuel tank, mounted directly between the saddle and the head tube. Some resemble motorized bicycles. Most are similar to a regular motorcycle but with pedals and a crankset that may be used with or instead of motor drive. Although mopeds usually have two wheels, some jurisdictions classify low-powered three- or four-wheeled vehicles (including ATVs and go-kart) as a moped. In some countries, a moped can be any motorcycle with an engine c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
