BMW M2B15
The BMW M2B15 was BMW's first flat-twin engine. Manufactured from 1920 to 1923, the M2B15 was intended to be a portable industrial engine, but it was used by several German motorcycle manufacturers to power their motorcycles. In 1920, BMW engineer Max Friz reverse-engineered the engine of foreman Martin Stolle's 1914 Douglas motorcycle and developed a similar 500 cc side-valve flat engine from it. This was referred to internally as the Type M2B15 and offered for sale officially as the "Bayern Motor". The engine was tried out by various motorcycle manufacturers. Starting in 1920, Victoria of Nuremberg Nuremberg (, ; ; in the local East Franconian dialect: ''Nämberch'' ) is the Franconia#Towns and cities, largest city in Franconia, the List of cities in Bavaria by population, second-largest city in the States of Germany, German state of Bav ... used the engine in their KR 1 motorcycle, and other manufacturers such as SMW and Bison also fitted it.

Flat-twin Engine
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the ''Lanchester 8 hp Phaeton'' car released in 1900. The flat-twin engine was used in several other cars since, however a more common usage is in motorcycles; early models oriented the cylinders in line with the frame, however later models switched to the cylinders being perpendicular to the frame to provide even cooling across both cylinders. Flat-twin engines were also used in several aircraft up until the 1930s and in various stationary applications from the 1930s to the 1960s. The Australian lawnmower manufacturer Victa also produced a flat-twin engine push mower from August 1975 to 1980 dubbed the ‘Twin 500’, and lat ...

Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1960s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cam-in-block
A cam-in-block engine is where the camshaft is located in the engine block In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attach .... Types of cam-in-block engines are: * F-Head Engine * Flathead engine * Overhead valve engine (the only type where the valves are above the combustion chamber) * T-head engine {{set index ...

Max Friz
Max Friz (October 1, 1883 – June 9, 1966) was a German mechanical engineer specializing in engine design. He was the key contributor of engine design and innovation that led to the founding of Bayerische Motoren Werke AG (BMW) in 1917. Early life Assumed to be originally from Urach, very little is known about Friz' youth. It is known however, that at a young age, he apprenticed to the Kuhn steam engine company in Cannstatt starting in 1898. In 1902, he enrolled at the Royal Building Trade School in Stuttgart-Esslingen furthering his engineering skills. In 1906, he was employed by Daimler Motoren Gesellschaft, in the Design Office, making major contributions to the design of the racing engine for the 1914 Mercedes Grand Prix car that won the French Grand Prix. Friz designed the first practical German aircraft engines in 1912-1913 while at Austro-Daimler. The engines had separate cylinders on the crankcase and an overhead camshaft driven by a vertical shaft and bevel gear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: information extraction, modeling, and review. Information extraction is the practice of gathering all relevant information for performing the operation. Modeling is the practice of combining the gathered information into an abstract model, which can be used as a guide for designing the new object or syst ...

Douglas (motorcycles)
Douglas was a British motorcycle manufacturer from 1907 to 1957 based in Kingswood, Bristol, owned by the Douglas family, and especially known for its horizontally opposed twin cylinder engined motorcycles and as manufacturers of speedway machines. The company also built a range of cars between 1913 and 1922. History The brothers William and Edwin Douglas founded the Douglas Engineering Company in Bristol in 1882. Initially doing blacksmith work, they progressed to foundry work. Joseph F. Barter's Light Motors Ltd. was one of Douglas's customers. Barter built a single-cylinder bicycle engine between 1902 and 1904; he then developed the Fée bicycle engine system. The Fée's 200 cc flat-twin engine was mounted in-line with the frame, using chain drive to a countershaft beneath (with clutch); this then used a drive belt to power the bicycle's rear wheel. Barter founded Light Motors Ltd. to build the Fée system. Production began in 1905, and the Fée's name was anglicized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks: in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine (Benz Contramotor) was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with fewer than six cylinders) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (motorcycle)
Victoria was a bicycle manufacturer in Nürnberg, Germany that made motorcycles from about 1901 until 1966. It should not be confused with a lesser-known, unrelated Victoria Motorcycle Company in Glasgow, Scotland that made motorcycles between 1902 and 1928. In its early decades Victoria in Nürnberg fitted proprietary engines purchased from various manufacturers including Fafnir, FN, Minerva and Zédel. 1920–1932 In 1920 Victoria launched the model KR 1, which has a 494 cc BMW twin-cylinder side-valve flat twin (boxer engine) mounted longitudinally in the motorcycle frame. The engine produced and transmission was via a two-speed gearbox. When BMW started making its own motorcycles, Victoria turned to making its own engines. In 1923 Victoria launched its KR 2, an overhead valve (OHV) flat twin producing . In 1924 Victoria followed this with the KR 3, which produces and has a 3-speed gearbox. In 1925 Victoria built Germany's first forced induction engine, and in 1926 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of BMW
The official founding date of the German motor vehicle manufacturer BMW is 7 March 1916, when an aircraft producer called ''Bayerische Flugzeugwerke'' (formerly '' Otto Flugmaschinenfabrik'') was established. This company was renamed to ''Bayerische Motoren Werke'' (BMW) in 1922. However, the BMW name dates back to 1917, when ''Rapp Motorenwerke'' changed its name to ''Bayerische Motoren Werke''. BMW's first product was a straight-six aircraft engine called the BMW IIIa. Following the end of World War I, BMW remained in business by producing motorcycle engines, farm equipment, household items and railway brakes. This was not enough and the company was suspended, effectively bankrupt, from 6 November 1918 to 1 February 1919. BMW turned to motorcycle engine manufacturing, building a smooth operating horizontally opposed engine to keep the centre of mass low and thus make a more responsive machine. The engine was well received but the motorcycles made using it were not and sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
