Fiat 100 Series Engine
Designed by Dante Giacosa, the Fiat 100 engine first appeared in a form in the all-new Fiat 600 in 1955. The in-line four-cylinder engine comprised an iron block and an aluminium cylinder head with pushrod actuated valves. The engine was produced at Fiat's Mirafiori (Turin) plant, and then at Bielsko-Biała, and remained in production until 2012 (Lada 1200 Ziguli), used in Fiat Panda and Fiat Seicento in its last capacity version fitted with SPI single-point injection and hydraulic tappets, although slowly being phased out starting from 1985 in favour of the new Fiat FIRE engine. It was also produced until 2008 in the Zastava plants in Kragujevac. Engine specifications The 100-series engine has a three main bearing crankshaft, a cast iron block and an aluminium cylinder head with an integrated intake manifold. The camshaft was placed in the block and was chain driven. There were 2 overhead valves per cylinder, actuated by an OHV valvetrain. Early versions were fed by a carb ...

Fiat Cinquecento
The Fiat Cinquecento (Type 170) (, ) is a front engine front-wheel-drive, four passenger, three door hatchback city car, manufactured and marketed by Fiat from 1991 to 1998 over a single generation. It was manufactured at Fiat Auto Poland, which had manufactured its predecessor the Fiat 126. Production of the Cinquecento ended in 1998, on introduction of the Fiat Seicento. Design The origins of the Cinquecento trace to the early 1980s, with focused research projects of the Consiglio Nazionale delle Ricerche in Rome, studying a super-economical vehicle – from which a series of prototypes evolved, with abbreviations X1/72 to X1/79. In parallel, FSM, not yet under FIAT's ownership, was studying the BOSMAL, a small car project that would culminate in the concept Beskid 106. Acquisition of FSM by the Italian automotive group led to the abandonment of this prototype in favor of a car that incorporated some of the concepts of the X1/7 series of previous years (until 1993 the ...

Single-point Injection
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present than what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically (by a fuel distributor), or electronically (by an engine control unit). Since the 1970s and 1980s, manifol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiat 850 Coupé
The Fiat 850 (''Tipo 100G'') is a small rear-engine, rear-wheel-drive car manufactured and marketed by Italian car manufacturer Fiat from 1964 to 1973. History Overview Its technical design was an evolution of the successful Fiat 600. The internal name for the Fiat 600 development project was "Project 100" and consequently, the internal Fiat codename for the 850 project was 100G (G was a follow on of model designations for the 600 which ran from A to F). The engine of the 850 was based on that of the Fiat 600, but had its capacity increased to 843 cc. The 850 came in two versions: "normale" (standard) with and engine code 100G.000 and "super" with and engine code 100G.002. The maximum speed was approximately . While it was not a large step forward in technical development, it possessed a certain charm with its large rolling eyes and its short tail, in which the engine sat. Variants The 850 family included several body styles sharing core technical components: * ''Fiat 850 Specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SEAT 800
The SEAT 600 is a city car made in Spain by SEAT from May 1957 until August 1973 under licence from Fiat. It helped to start the Spanish miracle (economic boom of 1959–1973) that came at the end of the slow recovery from the Spanish Civil War. It was a relatively inexpensive vehicle (then 60,000 Spanish pesetas) and was the first car that came within the modest but rapidly growing economic means of most Spanish families from the mid-1960s to the early 1970s. The vehicle has become an icon of the period. The SEAT company was born as a joint venture of the Spanish state holding agency National Institute of Industry, six Spanish banks and Fiat - almost all SEAT models up to 1982 were license-built Fiat-based cars, although the 1200/1430 Sport "''Boca negra''" and 133 were created in-house by SEAT in the 1970s. Up to 797,319 SEAT 600s and 18,000 SEAT 800s were made until 1973. They were exported to Argentina, Poland, and Finland. The Fiat version enjoyed far less success in its ho ...

Distributorless Ignition System
A distributor is an enclosed rotating switch used in spark-ignition internal combustion engines that have mechanically timed ignition. The distributor's main function is to route high voltage current from the ignition coil to the spark plugs in the correct firing order, and for the correct amount of time. Except in magneto systems and many modern computer controlled engines that use crank angle/position sensors, the distributor also houses a mechanical or inductive breaker switch to open and close the ignition coil's primary circuit. The first reliable battery operated ignition was the Delco ignition system developed by Dayton Engineering Laboratories Co. (Delco) and introduced in the 1910 Cadillac Model 30. This ignition was developed by Charles Kettering and was considered a wonder in its day. Atwater Kent invented his Unisparker ignition system about this time in competition with the Delco system. By the end of the 20th century mechanical ignitions were disappearing fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ...

Carburettor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American Engli ...

Chain Drive
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects. In other situations, a second gear is placed and the power is recovered by attaching shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go around corners by pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, t ...

Intake Manifold
In automotive engineering, an inlet manifold or intake manifold (in American English) is the part of an engine that supplies the fuel/ air mixture to the cylinders. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' epeatedly and refers to the multiplying of one (pipe) into many.manifold, (adv.) "in the proportion of many to one, by many times". AD1526 ''Oxford English Dictionary'', In contrast, an exhaust manifold collects the exhaust gases from multiple cylinders into a smaller number of pipes – often down to one pipe. The primary function of the intake manifold is to ''evenly'' distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is important to optimize the efficiency and performance of the engine. It may also serve as a mount for the carburetor, throttle body, fuel injectors and other components of the engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
