V - twin engine - wikipedia V - twin engine This article is about the two - cylinder V engine. For the Soviet V - 2 tank engine from World War II, see Kharkiv model V - 2. For other uses, see V2 ( disambiguation ). Harley - Davidson Road King 45 ° transversely mounted V - twin. A V - twin engine, also called a V2 engine, is a two - cylinder internal combustion engine where the cylinders are arranged in a V configuration. Although widely associated with motorcycles, V - twin engines are also produced for the power equipment industry and are often found in riding lawnmowers, small tractors and electric generators.

It was used as a stationary powerplant and to power boats. It was also used in Daimler 's second automobile, the 1889 Stahlradwagen ( `` steel - wheeled car '' ). The engine was also manufactured under licence in France by Panhard et Levassor. Princeps V - Twin ( Nov 1902 ) In November 1902 the Princeps AutoCar Co ( UK ) advertised a V - twin engined motorcycle, and in 1903 V - Twins were produced by other companies, including the 90 degree XL - ALL ( made by Eclipse Motor & Cycle Co in the UK ). Also, in 1903, Glenn Curtiss in the United States, and NSU in Germany began building V - twin engines for use in their respective motorcycles. Peugeot, which had used Panhard - built Daimler V - twins in its first cars, made its own V - twin engines in the early 20th century. A Norton motorcycle powered by a Peugeot V - twin engine won the first Isle of Man Tourist Trophy twin - cylinder race in 1907. Configurations Crankshaft configuration `` Fork & blade '' connecting rods Most V - twin engines have a single crankpin, which is shared by both connecting rods. The connecting rods may sit side - by - side with offset cylinders, or they may be `` fork & blade '' items with cylinders in the same plane without an offset. Some notable exceptions include the Moto Guzzi 500cc ( with 120 ° V angle and 180 ° crank pin offset ) that Stanley Woods rode to win the 1935 Isle of Man TT ; the 1983 Honda Shadow 750, claimed as being the first V - twin with an offset - dual - pin crankshaft ; and the 1987 Suzuki VX 800, 45 ° V angle with 45 ° crank pin offset in USA and 75 ° crank pin offset for the rest of the world. V angles Generally, any two - cylinder engine with its two cylinders arranged more than 0 ° and less than 180 ° apart is referred to as a V - twin. Although Ducati uses the name `` L - twin '' for its 90 ° twin engine ( with its front cylinder nearly horizontal and the rear cylinder almost vertical ), there is no technical distinction between V - twin and L - twin engines ; and these are merely names used by convention. A 90 ° V - twin will, with a correct counterweight, yield perfect primary balance, although its firing intervals are uneven. A V - twin with an angle of less than 90 ° is more compact and has more even firing intervals, but has significantly poorer mechanical balance. Offset crankpins are sometimes used to reduce the resulting vibration.

A Moto Guzzi Technical Services representative tried to explain to LA Times columnist Susan Carpenter that Moto Guzzi engines are `` called ' transverse ' because the engine is mounted with the crankshaft oriented front to back instead of left to right. '' In spite of this, it could be assumed that those who call V - twin motorcycle engines `` transverse '' when they are mounted with the crankshaft front - to - back and the cylinders sticking out the sides are saying that to them, the engine 's axis is the line passing from one cylinder to the other, at a right angle to the crankshaft, rather than going by the crankshaft 's axis. Highly technical sources, such as V. Cossleter 's Motorcycle Dynamics, or Gaetaeno Cocco 's Motorcycle Design and Technology are careful not simply to use the terms `` longitudinal engine '' or `` transverse engine, '' but rather to specify that they mark the engine 's orientation based on the crankshaft, and so they will say `` transverse crankshaft engine '' or `` longitudinal crankshaft engine '', or, conversely, `` transversely mounted cylinders '' in referenced to the classic BMW orientation, with a longitudinal crankshaft and cylinders at a right angle to the axis of the frame. Transverse crankshaft mounting Honda 90 ° transversely mounted V - twin. The engine can be mounted in transverse crankshaft position as on Harley - Davidsons, Ducatis and many recent Japanese motorcycles. This layout produces a twin cylinder motorcycle engine that is little or no wider than a single. A narrower engine can be mounted lower in the frame with handling benefits. A disadvantage of this configuration for air - cooled engines is that the two cylinders receive different air - flows and cooling of the rear cylinder tends to be restricted. Cooling problems are somewhat mitigated by having all `` four '' sides of each cylinder exposed to air flow. This differs from a parallel - twin cylinder engine which has a distinct front, back, and sides, but the inside of each cylinder is not exposed to airflow as the cylinders are typically joined together with a cam chain running up through the block in - between the cylinders. Some transverse V - twins use a single carburettor in the middle of the V - angle to feed both cylinders. While this allows an economy of parts, it creates further cooling problems for the rear cylinder by placing its hot exhaust port and pipe at the back of the cylinder, where it may be exposed to less cooling airflow. Some cooling strategies of transverse - crankshaft 90 ° V - twins This air - cooled Ducati Monster 620 has a transverse crankshaft 90 ° V - twin with one cylinder lying horizontally, and one vertically, so that the rearward, vertical cylinder 's air flow is less obstructed by the one in front. Honda 's VTR250 is similar, but the engine is not leaning forward, thus each cylinder is about 45 ° from vertical. The rear cylinder 's air flow is blocked, but note this is a water - cooled engine, so what most matters is that the radiator is out in front with good air flow. As the Ducati models get larger engines, they gain oil -, and then water - cooling, as in this Monster S4R S. Like the VTR250, the radiators are out in front, but the basic engine orientation retains the cooling advantages of the Monster 620. Longitudinal crankshaft mounting Moto Guzzi Jackal with a longitudinally mounted 90 ° V - twin. The longitudinal crankshaft two - cylinder V as seen on Moto - Guzzis and some Hondas is less common. This orientation is suited to shaft drive, eliminating the need for a 90 ° bevel gear at the transmission end of the shaft. A longitudinal crankshaft engine fits neatly into a typical motorcycle frame, leaving ample room for the transmission, and cooling is facilitated by cylinder heads and exhausts protruding into the air stream. Longitudinal crankshaft mounting is associated with a torque reaction that tends to twist the motorcycle to one side on sharp acceleration or when opening the throttle in neutral and in the opposite direction on sharp deceleration. Many modern motorcycle manufacturers correct for this effect by rotating flywheels or alternators in the opposite direction to that of the crankshaft. Automobile use BSA made a V - twin car starting in 1921, then introduced a three - wheeler in 1929. V - twin engines, adapted from motorcycles, were featured in Morgan three - wheelers made from 1911 to 1939. Morgan introduced a new Morgan 3 - Wheeler in 2011. A number of Morgan - inspired models are produced today including the Triking Cyclecar, which uses a Moto - Guzzi V - twin ; the Ace Cycle Car, which uses a V - twin Harley - Davidson engine ; and the JZR which uses engines from the Honda CX series. Mazda made 356 cc and 571 cc V - twins beginning in 1960 for the Mazda R360. V - twin engines installed in automobiles JAP water - cooled V - twin engine installed in front of the radiator of a 1934 Morgan Super Sports three - wheeled cyclecar. Air - cooled Mazda V - twin engine installed in the back of a Mazda R360 kei car. Commercial use Commercial equipment such as pressure washers, lawn and garden tractors, tillers, generators and water pumps use V - twin engines when that equipment is large enough to need more power, usually in excess of 16 horsepower, than can be provided by a single - cylinder engine. These V - twin engines have horizontal or vertical crankshafts, usually have 90 - degree cylinder angles, and are usually forced - air -- cooled. The V - twin configuration gives these engines a smaller footprint and less vibration, in the absence of balancing shafts, than other two - cylinder configurations. Manufacturers of such engines include Briggs & Stratton with its Vanguard, Professional and Intek V - twin Series, Honda with its V - twin series engines, Kawasaki with its FD, FH, FS, and FX series, Subaru with its EH series, Tecumseh with its OV691EA and TVT691 engines, and Kohler.

By 1934 Guzzi offered a range of 175, 250 and 500cc models including full touring machines. The next year they raised the ante once again, challenging the all - vanquishing Norton at the legendary Isle of Man TT, basically a course the British racer owned lock, stock and single barrel thanks to a phenomenal rider, Scotsman Jim Guthrie. Moto Guzzi went to a Brit for riding skills, one Stanley Woods. They gave him a new racer featuring a 120 - degree V - twin with offset cranks firing at 180 degrees with bevel gears and shafts driving the SOHC, good enough for 44 hp at 7500 rpm and 112 mph, on equal standing with the Norton. It had an ace up its sleeve so to speak in that it incorporated a type of pivoted - fork rear suspension while the frontend was a springer, a design that had never won a Senior TT due to its handling deficiencies, or so was thought. Guzzi had done some tweaking in that department as well. It also came equipped with a massive twin - leading shoe front brake, a 4 - speed gearbox, and alloy wheels, another innovation to cut down unsprung weight. When the dust had settled and the calculations determined, the wreath of victory went to Woods and Moto Guzzi, leaving Norton as they say, gobsmacked. Not only that, the Guzzi had smashed the track lap record. The next day Moto Guzzi was world famous. External link in work = ( help ) Jump up ^ `` Honda : 1983 Shadow 750 ''.

At some point in the motorcycle 's development, the company changed the crankpin offset from 45 to 75 degrees in hope of creating a smoother - running motor. But just as production began, American Suzuki engineers decided that the new offset resulted is less mid-range power as well as a too - sanitized exhaust note, one that did n't sound very V - Twin - like. Presto, now the US models come with the 45 - degree offset, while the rest of the world gets the 75 - degree staggered crankpins. ^ Jump up to : Vittore Cossalter. `` Shaking forces of twin engines ''.

It is called ' transverse ' because the engine is mounted with the crankshaft oriented front to back instead of left to right. Because of this you can not run a chain or belt drive directly to the rear wheel like in most motorcycles. This is why you have a separate gearbox that bolts to the engine and transfers the power to the rear wheel via the drive shaft. This is how it is done on the Moto Guzzi and a BMW.
