Suzuki SET
A four-stroke power valve is a device fitted to four-stroke engines that constantly adjusts the internal diameter of the exhaust system to better suit the speed of the engine. Yamaha was the first to develop such a system, called the Exhaust Ultimate Power Valve (EXUP). It first appeared on the Yamaha FZR EXUP and was later used on many other Yamahas. Later versions from Honda went by the names Honda Titanium Exhaust Valve (HTEV) and Honda Variable Intake/Exhaust (H-VIX), appearing on the CBR600RR and Honda CBR929RR. Suzuki's version is called Suzuki Exhaust Tuning (SET). The system is also used on the Triumph Daytona 675 triple. Operation At low engine speeds, the wave pressure within the pipe network is low. A full oscillation of the Helmholtz resonance occurs before the exhaust valve is closed, and to increase low-speed torque, large-amplitude exhaust pressure waves are artificially induced. This is done by partial closing of an internal butterfly valve within the exhaust whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda CBR600RR
The Honda CBR600RR is a sport bike made by Honda since 2003, part of the CBR series. The CBR600RR was marketed as Honda's top-of-the-line middleweight sport bike, succeeding the 2002 Supersport World Champion 2001–2006 CBR600F4i, which was then repositioned as the tamer, more street-oriented sport bike behind the technically more advanced and uncompromising race-replica CBR600RR. It carried the Supersport World Championship winning streak into 2003, and on through 2008, and won in 2010 and 2014. Model history Honda's previous 600-class sport bike, the CBR600F4i, was considered a balance of practicality and performance, as capable as other Supersport-racing 600s, but a more docile and comfortable street bike relative to the competing Kawasaki Ninja ZX-6R, Suzuki GSX-R600, and Yamaha YZF-R6. When introduced in 1999, the CBR600F "fought off racier contenders on the track while still managing to be a more practical streetbike", as described by ''Motorcyclist'', "one golf club ...

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 CBR929RR
The Honda CBR900RR, or FireBlade in some countries, is a sport bike, part of the CBR series introduced in 1992 by Honda. It was the first of a series of large-displacement Honda models to carry the RR suffix. The development of the first generation CBR900RR was led by Tadao Baba. History CBR900RR (893cc) SC28 The first generation CBR900RR was introduced in 1992 with an inline-four engine. It set a precedent for lightweight in the superbike class, being much lighter than other large-displacement bikes of the time. The CBR900RR was based on an advanced research stage model known within Honda as the "CBR750RR". With the objective of equaling the acceleration of competitors’ flagship sport bikes, Honda increased the stroke of its inline 4-cylinder 750 cc engine and thus raised displacement to 893cc. Complementing its power performance was the bike's dry weight of just 185 kg, wheelbase of 1,405 mm, and a body almost identical to that of the advanced research stage mo ...

Triumph Daytona 675
Introduced in 2006, the Triumph Daytona 675 is a three-cylinder sport bike, and the smallest of the Triumph triples. Built by Triumph Motorcycles, it replaced their four-cylinder Daytona 650. The 675 proved to be remarkably light, nimble and powerful; at a maximum of 128 bhp it was also very quick, and it was very successful against the Japanese 600 cc competition. In 2016, Triumph ceased production of the base model Daytona 675 citing diminishing demand for super sport bikes and increasingly strict European emission standards. Triumph continued to produce the up-spec Triumph Daytona 675R model until the 2018 model year. Triumph filed a new trademark for the Daytona, fuelling rumors that there may be a future version sporting the new 765 cc engine. History and development Triumph Daytona 675 development started in 2000 following the launch of the four-cylinder TT600. The TT600 was Triumph's first modern middleweight sports motorcycle, but it struggled to comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engines, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976-1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees. ...

Helmholtz Resonance
Helmholtz resonance or wind throb is the phenomenon of air resonance in a cavity, such as when one blows across the top of an empty bottle. The name comes from a device created in the 1850s by Hermann von Helmholtz, the ''Helmholtz resonator'', which he used to identify the various frequencies or musical pitches present in music and other complex sounds.Helmholtz, Hermann von (1885), ''On the sensations of tone as a physiological basis for the theory of music'' Second English Edition, translated by Alexander J.

Butterfly Valve
A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. Principle of operation Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In control engineering a servomechanism, usually shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. On displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a car's cruise control uses closed-loop feedback, which classifies it as a servomechanism. Applications Position control A common type of servo provides ''position control''. Commonly, servos are electric, hydraulic, or pneumatic. They operate on the principle of negative feedback, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
