Turbocharged Petrol Engines
Turbochargers have been used on various petrol engines since 1962, in order to obtain greater power or torque output for a given engine displacement. Most turbocharged petrol engines use a single turbocharger; however, twin-turbo configurations are also often used. In motor racing, turbochargers were used in various forms of motorsport in the 1970s and 1980s. Since the mid-2010s, turbocharging has returned to several motor racing categories, such as Formula One and the World Rally Championship. Several motorcycles in the late 1970s and early 1980s were produced with turbocharged engines. History *1962: The first turbocharged production car engine was the Oldsmobile Turbo Jetfire used in the Oldsmobile Jetfire. A Garrett AiResearch turbocharger with integral wastegate was used. Power was significantly increased over the naturally aspirated (non-turbo) engine, however reliability of these engines was poor and the production of the engine ceased in 1963. One month after the releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbochargers
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Bugatti Chiron
The Bugatti Chiron is a mid-engine two-seater sports car designed and developed in Germany by Bugatti Engineering GmbH and manufactured in Molsheim, France, by French automobile manufacturer Bugatti Automobiles S.A.S. The successor to the Bugatti Veyron, the Chiron was first shown at the Geneva Motor Show on 1 March 2016. The car's design was initially previewed with the Bugatti Vision Gran Turismo concept car unveiled at the 2015 Frankfurt Auto Show. The car is named after the Monégasque driver Louis Chiron. The car shares the name with the 1999 Bugatti 18/3 Chiron concept car. __TOC__ Specifications and performance The main carry over component from the Veyron is the quad-turbocharged W16 engine, though it is heavily updated. The engine in the Chiron has a peak power output of at 6,700 rpm and of torque starting from 2,000 to 6,000 rpm. The engine in the most powerful variant of its predecessor, the Veyron Super Sport generates less than the new Chiron, whil ...

1988 Formula One World Championship
The 1988 FIA Formula One World Championship was the 42nd season of FIA Formula One motor racing. It featured the 1988 Formula One World Championship for Drivers and the 1988 Formula One World Championship for Constructors, which were contested concurrently over a sixteen-race series that commenced on 3 April and ended on 13 November. The World Championship for Drivers was won by Ayrton Senna, and the World Championship for Constructors by McLaren-Honda. Senna and McLaren teammate Alain Prost won fifteen of the sixteen races between them; the only race neither driver won was the Italian Grand Prix, where Ferrari's Gerhard Berger took an emotional victory four weeks after the death of team founder Enzo Ferrari. McLaren's win tally has only been bettered or equalled in seasons with more than sixteen races; their Constructors' Championship tally of 199 points, more than three times that of any other constructor, was also a record until .

1977 Formula One Season
The 1977 Formula One season was the 31st season of the FIA's Formula One motor racing. It featured the 28th World Championship of Drivers and the 20th International Cup for Formula 1 Constructors, which commenced on 9 January 1977, and ended on 23 October after seventeen races, making it the longest Formula One season in the sport's history at the time. The season also included a single non-championship race for Formula One cars, the 1977 Race of Champions. Niki Lauda won his second championship, despite Mario Andretti winning more races. Jody Scheckter's Wolf won first time out, Shadow took their only victory, and Gunnar Nilsson achieved the only win of a career ended by cancer. Renault entered Grand Prix racing with a turbocharged car which was initially not very successful. The German ATS team took over the Penske cars and the South African Grand Prix was the last race a BRM ever qualified to start. Lauda departed Ferrari even before the season ended, so did not complete t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issued ...

Ferrari 126C
The Ferrari 126C is the car with which Ferrari raced in the 1981 Formula One season. The team's first attempt at a turbocharged Formula 1 car, it was designed by Mauro Forghieri and Harvey Postlethwaite and used between the 1981 and 1984 seasons. The engine chief engineer was Nicola Materazzi. Development and race history 126C (1981): Comprex vs Turbo The Ferrari 126C was designed to replace the highly successful but obsolete 312T series in use since . The basic chassis was almost identical to the previous car but the smaller and narrower V6 engine with forced induction, better suiting the ground effect aerodynamics now needed to be competitive (the previous car's wide flat-12 boxer engine obstructed the airflow necessary to generate efficient ground effect), and was a better package overall. During engine development Ferrari started experimenting with a ''Comprex'' pressure wave supercharger, supplied by a Swiss company; this car version was initially called 126BBC from th ...

Can-Am
The Canadian-American Challenge Cup, or Can-Am, was an SCCA/ CASC sports car racing series from 1966 to 1987. History Can-Am started out as a race series for group 7 sports racers with two races in Canada (''Can'') and four races in the United States of America (''Am''). The series was initially sponsored by Johnson Wax. The series was governed by rules called out under the FIA group 7 category with unrestricted engine capacity and few other technical restrictions. The group 7 category was essentially a Formula Libre for sports cars; the regulations were minimal and permitted unlimited engine sizes (and allowed turbocharging and supercharging), virtually unrestricted aerodynamics, and were as close as any major international racing series ever got to have an "anything goes" policy. As long as the car had two seats, bodywork enclosing the wheels, and met basic safety standards, it was allowed. Group 7 had arisen as a category for non-homologated sports car "specials" in Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 917
The Porsche 917 is a sports prototype race car developed by German manufacturer Porsche to exploit the regulations regarding the construction of 5-litre sports cars. Powered by a Type 912 flat-12 engine which was progressively enlarged from 4.5 to 5.0 litres, the 917 was introduced in 1969 and initially proved unwieldy on the race track but continuous development improved the handling and it went on to dominate sports-car racing in 1970 and 1971. In 1970 it gave Porsche its first overall win at the 24 Hours of Le Mans, a feat it would repeat in 1971. It would be chiefly responsible for Porsche winning the International Championship for Makes in 1970 and 1971. Porsche went on to develop the 917 for Can-Am racing, culminating in the twin-turbocharged 917/30 which was even more dominant in the role. Porsche drivers would win the Can-Am championship in 1972 and 1973. 917 drivers also won the Interserie championship every year from 1969 to 1975. Origins of the 917 In an effor ...

1968 Indianapolis 500
The 52nd International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Thursday May 30, 1968. For the second year in a row, one of Andy Granatelli's STP Turbine-powered machines was leading late in the race, but once again, it failed within sight of victory. On lap 174, Lloyd Ruby's engine misfired allowing Joe Leonard to take the lead in the Lotus 56 Turbine. Leonard, however, suffered a flameout on the lap 191 restart, and rolled to a silent and shocking halt. Bobby Unser in the venerable piston-powered Offenhauser, inherited the lead, and despite gear linkage trouble, won the first of his three Indy 500 victories (1968, 1975, 1981). This was the final Indianapolis 500 to feature a front-engined car in the starting field. Of the 33 cars, 32 were rear-engined machines (including three turbines). Jim Hurtubise's entry, which dropped out after only nine laps, was the last front-engine car to race in the 500. This was also the first 500 w ...

1966 Indianapolis 500
The 50th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Monday, May 30, 1966. The official program cover for the race celebrated both the 50th running of the race, and 150th anniversary of Indiana statehood. Eleven of the 33 starters were eliminated in a first-lap accident right after receiving the green flag on the main stretch. Only A. J. Foyt was injured, hurting his hand scaling the catch fence trying to escape the wreck scene. Only seven cars, the fewest finishers ever, were still running by the end of the race. First-time starter Jackie Stewart led by over a lap late in the race in John Mecom's Lola T90-Ford.Kettlewell, p. 2192. However, inside ten laps to go, his oil pressure dropped too low due to a broken scavenge pump. Stewart parked the car, and after briefly attempting to push some ways, he walked back to the pits. Fellow rookie Graham Hill inherited the lead and led a total of 10 laps to win, the first rooki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offenhauser
The Offenhauser Racing Engine, or Offy, is a racing engine design that dominated American open wheel racing for more than 50 years and is still popular among vintage sprint and midget car racers. History The Offenhauser engine, familiarly known as the "Offy", was an overhead cam monoblock 4-stroke internal combustion engine developed by Fred Offenhauser and Harry Arminius Miller. Originally, it was sold as a marine engine. In 1930 a four-cylinder Miller engine installed in a race car set a new international land speed record of . Miller developed this engine into a twin overhead cam, four-cylinder, four-valve-per-cylinder racing engine. Variations of this design were used in midgets and sprints into the 1960s, with a choice of carburetion or Hilborn fuel injection. When both Miller and the company to whom he had sold much of the equipment and rights went bankrupt in 1933, Offenhauser opened a shop a block away and bought rights to engines, special tooling and draw ...

1952 Indianapolis 500
The 36th International 500-Mile Sweepstakes was a motor race held at the Indianapolis Motor Speedway on Friday, May 30, 1952. It was the opening race of the 1952 AAA National Championship Trail and was also race 2 of 8 in the 1952 World Championship of Drivers. Troy Ruttman won the race for car owner J. C. Agajanian. Ruttman, aged 22 years and 80 days, set the record for the youngest 500 winner in history. It was also the last dirt track car to win at Indy. Ruttman's win also saw him become the youngest winner of a World Drivers' Championship race, a record he would hold for 51 years until the 2003 Hungarian Grand Prix when Spanish driver Fernando Alonso won at the age of 22 years and 26 days. Bill Vukovich led 150 laps, but with 9 laps to go, he broke a steering linkage while leading. He nursed his car to a stop against the outside wall, preventing other cars from getting involved in the incident. In the third year that the 500 was included in the World Championship, Ferra ...
