Flat-twin
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 as the ‘Twin 500’ and ...

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 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 less than six cylinders) and V engines (for engi ...

Citroën 2CV
The Citroën 2CV (french: link=no, deux chevaux(-vapeur), , lit. "two steam horse(power)s", meaning "two ''taxable'' horsepower") is an air-cooled front-engine, front-wheel-drive, economy family car, introduced at the 1948 Paris Mondial de l'Automobile, and manufactured by Citroën for model years 1948–1990. Conceived by Citroën Vice-President Pierre Boulanger to help motorise the large number of farmers still using horses and carts in 1930s France, the 2CV has a combination of innovative engineering and straightforward, utilitarian bodywork — at first with extra thin panels, reinforced by ''corrugating'' the metal. The 2CV featured overall low cost of ownership, simplicity of maintenance, an easily serviced air-cooled engine (originally offering 9 hp), and minimal fuel consumption. In addition, it had literally been designed to cross a freshly ploughed field, because of the great lack of paved roads in France then; with a long-travel suspension system, that con ...

Toyota Publica
The is a small car manufactured by the Japanese automaker Toyota from 1961 until 1978. Conceived as a family car to fulfill the requirements of the Japanese Government's "national car concept", it was the smallest Toyota car during that period and was superseded in that role by the Toyota Starlet, which itself started out as a version of the Publica. It was available as a 2-door vehicle only, but in a selection of body styles, ranging from the base sedan through a station wagon, convertible, coupé and even a coupe utility (pickup), which outlived the other models by a decade, and spawned other models, such as the Toyota Sports 800 and the Toyota MiniAce. Development MITI "national car" concept The origins of the Publica can be traced to the " national car" concept of the powerful Japanese Ministry of International Trade and Industry (MITI), which was announced in 1955. The concept stipulated for a vehicle fulfilling several requirements, like maximum speed over , weight bel ...

BMW 600
The BMW 600 is a four-seater microcar produced by the German automaker BMW from mid-1957 until November 1959. Partially based on the BMW Isetta two-seater, it was BMW's first postwar four-seater economy car. It was not a sales success, but it began the design process for its more successful successor, the BMW 700. Concept, design, and engineering BMW needed to expand its model range, but they did not have the resources to develop an all-new car with an all-new engine. Therefore, it used the Isetta as starting point for a new four seat economy car. As a result, the 600 used the front suspension and front door of the Isetta. The need to carry four people required a longer frame, a different rear suspension, and a larger engine. A new perimeter frame was designed, using box section side members and straight tube crossmembers. The rear suspension was an independent semi trailing arm design; this was the first time BMW had used this system. The chassis had a wheelbase of , a fron ...

Jowett Bradford
The Jowett Bradford was a British light van produced from 1946 to 1953 by Jowett Cars Ltd of Idle, near Bradford, England. It was also available as an estate car from 1947 to 1953. The vehicle was based on the pre-war Jowett Eight and was the first Jowett to be re-introduced after the Second World War. Although it was very basic, the Bradford's economy and availability appealed to the post-war market. Design features The chassis featured half-elliptic leaf springs front and rear with beam axles. The front-mounted flat-twin engine produced and drove the rear wheels through a three-speed non-synchromesh gearbox. In 1950 the engine was updated to give and synchromesh was fitted to the top ratio. This improved the top speed to . The drum brakes were operated mechanically using a Girling system. Body variants Initially only a 10 cwt van version was made but in 1947 it was joined by an estate car, the Utility. This was little more than the van with side windows and r ...

Wasted Spark
A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines. In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus "wasted". This design halves the number of components necessary in a typical ignition system, while the extra spark, against much reduced dielectric resistance, barely impacts the lifespan of modern ignition components. In a typical engine, it requires only about 2–3 kV to fire the cylinder on its exhaust stroke. The remaining coil energy is available to fire the spark plug in the cylinder on its compression stroke (typically about 8 to 12 kV). Advantages Perhaps the most significant advantage of the system, compared to a single coil and distributor systems, is that it eliminates the high-tension distributor. This significantly ...

Firing Order
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder. Four-stroke engines must also time the valve openings relative to the firing order, as the valves do not open and close on every stroke. Firing order affects the vibration, sound and evenness of power output from the engine and heavily influences crankshaft design. Cylinder numbering Numbering systems for car engines The numbering system for cylinders is generally based on the cylinder numbers increasing from the front to the rear of an engine (See engine orientation below). However, there are differences between manufacturers in how this is applied; some commonly used systems are as listed below. ;Straight engine Cylinders numbered from front ...

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 ...

Panhard
Panhard was a French motor vehicle manufacturer that began as one of the first makers of automobiles. It was a manufacturer of light tactical and military vehicles. Its final incarnation, now owned by Renault Trucks Defense, was formed by the acquisition of Panhard by Auverland in 2005, and then by Renault in 2012. In 2018 Renault Trucks Defense, ACMAT and Panhard combined under a single brand, Arquus. History Panhard was originally called Panhard et Levassor, and was established as an automobile manufacturing concern by René Panhard and Émile Levassor in 1887. Early years Panhard et Levassor sold their first automobile in 1890, based on a Daimler engine license. Levassor obtained his licence from Paris lawyer Edouard Sarazin, a friend and representative of Gottlieb Daimler's interests in France. Following Sarazin's 1887 death, Daimler commissioned Sarazin's widow Louise to carry on her late husband's agency. The Panhard et Levassor license was finalised by Louise, w ...
