KTM 690 Duke R
The KTM 690 Duke is the latest generation in KTM's line of midrange single-cylinder engine supermoto, or naked motorcycles that began with the 1994 displacement Duke 620 or Duke I, followed by the 1998 Duke 640 or Duke II, followed by the Duke III, and finally the Duke IV made since 2012. Both the Duke III and Duke IV are called the 690 Duke The Duke was KTM's first street bike, and first supermoto, having previously made only off-road and racing motorcycles. In 1998 KTM introduced the 640 Supermoto, so the Duke line became a more street oriented standard or streetfighter, while retaining some off-road characteristics like a relatively long suspension travel. Initially the Duke was KTM's entry level street bike, but later KTM partnered with Bajaj Auto Bajaj Auto Limited () is an Indian multinational automotive manufacturing company based in Pune. It manufactures motorcycles, scooters and auto rickshaws. Bajaj Auto is a part of the Bajaj Group. It was founded by Jamnalal ...

Dell'Orto
Dell'Orto is an Italian company, headquartered in Cabiate, specialized in the construction of carburetors and electronic injection systems. The company was founded in 1933 as "Società anonima Gaetano Dell'Orto e figli" (Gaetano Dell’Orto and Sons) but actually only founded by Gaetano's sons, Luigi Piero and Giuseppe. The first production was carburetors for motorbikes. Right before World War II the company started producing carburetors with aluminum body, for competitive racing. Under the second Dell'Orto generation, towards the end of the 60s, the company began producing OEM carburetors for the Fiat group, as well as other Italian and foreign manufacturers (i.e. Flandria, Belgium). At the end of the 1980s, under the supervision of Luigi Dell'Orto (son of Gaetano), the company's first injection systems were released. In 2006, the company expanded on the Indian market, opening Dell'Orto India. In September 2009, Dell’Orto India Private Limited, founded in 2006 with the coope ...

Electric Starter
A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic. The starter can also be another internal-combustion engine in the case, for instance, of very large engines, or diesel engines in agricultural or excavation applications. Internal combustion engines are feedback systems, which, once started, rely on the inertia from each cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two (intake, compression) strokes of the next cycle, as well as powering the engine's external load. To start the first cycle at the beginning of any particular session, the first two strokes must be powered in some other way than from the engine itself. The starter motor is used for this purpose and it is not re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Release
A compression release mechanism works to ease the starting of internal combustion engines by allowing them to spin up to starting speed without having to work against the pumping action of the pistons. It does this through a release valve that is incorporated within the cylinder head that vents the cylinder pressure to the outside atmosphere until the engine has sufficient momentum to overcome it. At that point the valve closes and the ignition is engaged. Motorcycles Early large displacement motorcycles provided riders with a manual control for this when kick starters were used while later models linked them to the kick start lever through a cable for automatic operation. Though it only uses electric start, not kick start, the 2012 Ducati 1199 uses a compression release, which is automatically activated at low engine speed by a centrifugal flyweight on each exhaust cam. This reduces the work of cranking the high 12.5:1 compression ratio engine, allowing a smaller battery and small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kick Start
Kick start is a method of starting an internal combustion engine (usually that of a motorcycle) by pushing a ratcheting lever with one's foot. Kick start mechanisms were almost universally a part of motorcycle engines before the mid-1970s, and were phased out of production over the next twenty years or so as electric starters became standard equipment. There are still some motorcycles produced that have both kick and electric starters. Many mopeds and scooters also carry both a kick start and an electric start, the former being useful in case the latter fails, as scooter and moped batteries tend to be smaller and, as a result, run down much faster than other forms of automotive batteries. Also, it is usually not possible to push start a moped or scooter with automatic transmission. Larger motorcycles featured a manual compression release mechanism that made starting easier while modern units did this automatically through a cable attached to the kick start lever. Today, dedic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-cylinder Engine
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

SOHC
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 en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multivalve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which can redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
