The straight-eight engine or inline-eight engine is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase. The type has been produced in side-valve, IOE, overhead-valve, sleeve-valve, and overhead-cam configurations.
An overhead camshaft (OHC) engine is a type of piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block.
The Alfa Romeo 164 is a four-door executive saloon manufactured and marketed by Italian automaker Alfa Romeo from 1987-1998, styled by Pininfarina, and cooperatively designed and sharing platforms and numerous elements with the Fiat Croma, Saab 9000 and Lancia Thema.
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
Vittorio Jano was an Italian automobile designer of Hungarian descent from the 1920s through 1960s.
The Alfa Romeo 8C was originally a range of Alfa Romeo road, race and sports cars of the 1930s. In 2004 Alfa Romeo revived the 8C name for a V8-engined concept car which made it into production for 2007, the 8C Competizione.
Alfa Romeo Twin Spark (TS) technology was used for the first time in the Alfa Romeo Grand Prix car in 1914. In the early 1960s it was used in their race cars (GTA, TZ) to enable it to achieve a higher power output from its engines. And in the early and middle 1980s, Alfa Romeo incorporated this technology into their road cars to enhance their performance and to comply with stricter emission controls.
The Alfa Romeo Twin Cam engine is an all-alloy inline-four engine series produced by Alfa Romeo from 1954 to 1994. In Italian it is known as the "bialbero" ("twin-shaft"), and has also been nicknamed the "Nord" (North) engine in reference to its being built in Arese, close to Milan, in the North of Italy and to distinguish it from the Alfa Romeo Boxer engine built in the South (Sud) for the Alfasud.
The Alfa Romeo V6 engine is a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and first used on the Alfa 6 with a displacement of 2.5 L (2,492 cc) and a SOHC 12-valve cylinder head. Later versions ranged from 1,996 to 3,179 cc and had DOHC 24-valve valvetrains. The original design had short pushrods for the exhaust valves in a design similar to earlier Lancia Fulvia engines. The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves.
The Alfa Romeo Giulia TZ was a sports car and racing car manufactured by Alfa Romeo from 1963 to 1967. It replaced the Giulietta SZ. In 2011, the name was reduced from Giulia TZ to TZ in the new TZ3 model.
The Alfa Romeo 158/159, also known as the Alfetta, is a Grand Prix racing car produced by Italian manufacturer Alfa Romeo. It is one of the most successful racing cars ever; the 158 and its derivative, the 159, took 47 wins from 54 Grands Prix entered. It was originally developed for the pre-World War II voiturette formula (1937) and has a 1.5-litre straight-8 supercharged engine. Following World War II, the car was eligible for the new Formula One introduced in 1947. In the hands of drivers such as Nino Farina, Juan Manuel Fangio and Luigi Fagioli, it dominated the first two seasons of the World Championship of Drivers.
Giuseppe Merosi was an Italian automobile engineer and designer.
Alfa Romeo P1 or Alfa Romeo Tipo P1 was the first Grand Prix car made by Alfa Romeo in 1923. The car had a 2.0 L straight-6 engine and it produced 95 bhp (71 kW) at 5000 rpms. The bore and stroke were 65mm and 100mm, respectively. Three cars were entered in the Italian GP at Monza in 1923, for Antonio Ascari, Giuseppe Campari and Ugo Sivocci. When Sivocci was practicing for the GP in September 1923 he crashed and was killed. Alfa Romeo withdrew from the competition and development of the car was stopped. In 1924 a new version with Roots-compressor was made and became the P1 Compressore 1924.
The Maserati 4CL and its derived sister model the Maserati 4CLT are single-seat open-wheel Grand Prix racing cars that were designed and built by Maserati. The 4CL was introduced at the beginning of the 1939 season, as a rival to the Alfa Romeo 158 and various ERA models in the voiturette class of international Grand Prix motor racing. Although racing ceased during World War II, the 4CL was one of the front running models at the resumption of racing in the late 1940s. Experiments with two-stage supercharging and tubular chassis construction eventually led to the introduction of the revised 4CLT model in 1948. The 4CLT was steadily upgraded and updated over the following two years, resulting in the ultimate 4CLT/50 model, introduced for the inaugural year of the Formula One World Championship in 1950. In the immediate post-war period, and the first two years of the Formula One category, the 4CLT was the car of choice for many privateer entrants, leading to numerous examples being involved in most races during this period.
The Alfa Romeo Tipo 308 or 8C-308 is a Grand Prix racing car made for the 3 litre class in 1938. Only four cars were produced, actually modified from Tipo C with the engine mounted lower into the chassis and a slimmer body. The chassis was derived from the Tipo C and the engine from the 8C 2900. The 308 was engineered by Gioacchino Colombo under the control of Enzo Ferrari who was then in charge of Alfa's racing team, Alfa Corse. The car debuted at the Pau Grand Prix in 1938, where two cars were entered to race, one for Tazio Nuvolari and the other for Luigi Villoresi. Both drivers had to withdraw from competition, however Nuvolari had by then set a lap record. The next race was the Tripoli Grand Prix. The new 312 and 316 were entered, but they had engine trouble during practice and Clemente Biondetti took the start at the wheel of the 308 held in reserve. He failed to finish, while Hermann Lang, driving a Mercedes-Benz W154, was the winner. In this race, Eugenio Siena, driving a 312, was killed after hitting a wall.
The Alfa Romeo 12C or Tipo C was a 12-cylinder Grand Prix car. The 12C-36 made its debut in Tripoli Grand Prix 1936, and the 12C-37 in Coppa Acerbo 1937. The 12C-36 was a Tipo C fitted with the new V12 instead of the 3.8 litre straight-eight of the 8C-35. The 12C-37 was a new car, with a lower chassis and an engine bored and stroked to 4475 cc, now with roller- instead of plain bearings and two smaller superchargers instead of a single large one. The car suffered poor handling, which could not be cured in time for the 1937 Italian GP, and thus was not successful. This is given as the reason for Vittorio Jano's resignation from Alfa Romeo at the end of 1937. The 12C-36 used the existing six Tipo C chassis. Four examples of the 12C-37 were built, although only two were actually assembled for the 1937 Coppa Acerbo and Italian GP. Early in 1938, the Tipo C chassis were modified into 308s, with the straight-eight engine fitted lower in the chassis and a completely new body. The four 12C-37 chassis were instead assembled into 312 and 316 formula race cars.
Italian motor manufacturer Alfa Romeo has participated many times in Formula One. It currently participates as Alfa Romeo F1 Team Stake while being operated by Sauber Motorsport AG. The brand has competed in motor racing as both a constructor and engine supplier sporadically between 1950 and 1987, and later as a commercial partner since 2015. The company's works drivers won the first two World Drivers' Championships in the pre-war Alfetta: Nino Farina in 1950 and Juan Manuel Fangio in 1951. Following these successes, Alfa Romeo withdrew from Formula One.
This article gives an outline of Formula One engines, also called Formula One power units since the hybrid era starting in 2014. Since its inception in 1947, Formula One has used a variety of engine regulations. "Formulae" limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era.
The Viper engine is a high-performance naturally-aspirated pushrod 2 valves-per-cylinder 90° V10 engine designed by Chrysler but with aluminum block castings designed by Lamborghini for use in the Dodge Viper. Despite its large displacement, it is based on the Chrysler LA V8.
