Desaxe
A desaxe engine, is one in which each cylinder is positioned with its exact center (the bore axis) slightly offset from the center line of the crankshaft. "Désaxé", in French, means "unbalanced". Desaxe engines are usually automotive, but the term can also apply to steam engines. If the offset is in the direction of rotation, it has the effect of increasing the leverage applied to the crankshaft during the "power" stroke, and reducing thrust wasted against the cylinder wall. In a conventional four-stroke engine, each of the strokes (intake, compression, power, exhaust) involves a nominal rotation of 180°, totaling 720° for the complete 4-stroke combustion cycle. A desaxe engine adds to the duration of the two downward strokes (intake and power), and subtracts the same amount from the two upward strokes (compression and exhaust), with the total remaining 720°. A typical desaxe engine will have strokes of 185° - 175° - 185° - 175°, etc., with the differential roug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.

Puch
Puch () is a manufacturing company located in Graz, Austria. The company was founded in 1899 by the industrialist Johann Puch and produced automobiles, bicycles, mopeds, and motorcycles. It was a subsidiary of the large Steyr-Daimler-Puch conglomerate. History Foundation From 1889 Johann Puch (1862–1914) worked as an agent for Humber vehicles and manufacturer of ''Styria'' safety bicycles in a small workshop in Graz and in 1890 he founded his first company, Johann Puch & Comp., employing 34 workers. Cyclists like Josef Fischer, winning the first edition of Paris–Roubaix in 1896, popularized ''Styria'' bicycles which were even exported to England and France. By 1895, Puch already employed more than 300 workers producing about 6000 bikes a year. In 1897 Puch left the company after a dispute with his business partners. Two years later he founded the First Styrian Bicycle Factory AG (''Erste Steiermärkische Fahrradfabrik AG'') in Graz. Puch's company became successful throu ...

Split-single
In internal combustion engines, a split-single design is a type of two-stroke where two cylinders share a single combustion chamber. The first production split-single engine was built in 1918 and the design was used on several motorcycles and cars until the mid 1950s, although one company continued producing split-single engines for motorcycles until 1970. During this time, the design was also occasionally used for engines with four or more cylinders. Principle of operation The split-single uses a two-stroke cycle (i.e. where every downward stroke produces power) with the following phases: # Pistons travel upwards, compressing the fuel-air mixture in both cylinders. A spark plug ignites the mixture (in the right side cylinder in the animation) when the pistons are near the top of the cylinders. # Pressure from the ignited air-fuel mixture pushes both pistons downwards. Near the bottom of the travel, an exhaust port becomes exposed (in the left side cylinder in the animation), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yamaha MT-09
The Yamaha MT-09 is a street motorcycle of the MT series with an liquid-cooled four-stroke 12-valve DOHC inline-three engine with crossplane crankshaft and a lightweight cast alloy frame. For 2018, the bike is now designated MT-09 in all markets. Design and development The MT-09 competes against the Triumph Street Triple, Kawasaki Z900, and MV Agusta Brutale 800. It is intended to restore Yamaha's fortunes, as the factory has in recent years lost its reputation for innovation. The MT-09's product manager, Shun Miyazawa, said Yamaha had considered parallel-twins, inline-threes, inline-fours, and V-twins, but that the inline-three gave the "best solution" of power, torque, and low weight. Comparing the MT-09 to the Street Triple, he said the Triumph was a streetfighter, but the Yamaha was a "roadster motard".MotorCycle News 4 September 2013, page 11 Both the frame and the double-sided swingarm are made of lightweight alloy, which are cast in two pieces. The frame castin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VR6 Engine
VR6 engines are V6 piston engines with a narrow angle between the cylinder banks and a single cylinder head covering both banks of cylinders. Volkswagen Group introduced the first VR6 engine in 1991 and VR6 engines currently remain in production. From 1997 to 2006, Volkswagen also produced a five-cylinder VR5 engine based on the VR6. Description The name VR6 comes from the German initials for a V engine (German: ''V-Motor'') and a straight (inline) engine (German: ''Reihenmotor''), therefore the VR engine is described as a "Vee-Inline engine" (VR-Motor). VR6 engines share a common cylinder head for the two banks of cylinders. Only two camshafts are needed for the engine, regardless of whether the engine has two or four valves per cylinder. This simplifies engine construction and reduces costs. Since the cylinders are not located on the centreline of the combined cylinder head, the lengths of the intake and exhaust ports are different for each bank. Without compensation, ...

Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ... [...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 ...
