It was the result of a Ford Motorsport project with the purpose of producing an outright winner for Group A racing in Europe. The project was defined by Stuart Turner in the spring of He had recently been appointed head of Ford Motorsport in Europe, and he realised right away that Ford was no longer competitive in this area.
Turner got in touch with Walter Hayesat the time the vice-president of public relations at Ford, to get support for the project. Hayes had earlier been the driving force behind the development of the Ford GT40 that won Le Mans inand the Cosworth DFV engine that brought Ford victories and 12 world championships in Formula One during the s and s.
Hayes found the project very appealing and promised his full support. Turner then invited Ken Kohrs, vice-president of development, to visit Ford's longtime partner, the automotive company Cosworthwhere they were presented a project developed on Cosworth's own initiative, the YAA engine. This was a twin camvalve engine based on Ford's own T88 engine block, better known as the Pinto.
This prototype proved an almost ideal basis for the engine Turner needed to power his Group A winner. Turner's project would only need about 5, engines, but Ford nevertheless accepted the conditions. The extra 10, engines would later become one of the reasons Ford also chose to develop a four-door, second generation, Sierra RS Cosworth.
To find a suitable gearbox proved more challenging. The Borg-Warner T5also used in the Ford Mustangwas chosen, but the higher revving nature of the Sierra caused some problems.
Eventually Borg-Warner had to set up a dedicated production line for the gearboxes to be used in the Sierra RS Cosworth. Much of Ford's external documentation for customer race preparation indicated "developed for the XR4Ti" when describing parts that were Sierra Cosworth specific.
Some production parts from the XR4Ti made their way into the Cosworth such as the speedometer with integral boost gauge and the motorsport chassis stiffening plates. In AprilTurner's team decided on the Sierra as a basis for their project. The Sierra filled the requirements for rear wheel drive and decent aerodynamic drag.
A racing version could also help to improve the poor, and somewhat undeserved, reputation that the Sierra had earned since its introduction in Lothar Pinske, responsible for the car's bodywork, demanded carte blanche when it came to appearance in order to make the car stable at high speed.
Experience had shown that the Sierra hatchback body generated significant aerodynamic lift even at relatively moderate speed. This was based on an XR4i body with provisional body modifications in fibreglass and aluminium. The car's appearance raised little enthusiasm. The large rear wing caused particular reluctance. Pinske insisted, however, that the modifications were necessary to make the project successful. Eventually, the Ford designers agreed to try to make a production version based on the prototype.
A requirement for participation in Group A was that 5, cars were built and sold. The feedback was not encouraging. The dealers estimated they could sell 1, cars. Hayes did not give up, however, and continued his passionate internal marketing of the project. As prototypes started to emerge, dealers were invited to test-drive sessions, and this increased the enthusiasm for the new car. In addition, Ford took some radical measures to reduce the price on the car.
As an example, the car was only offered in three exterior colours black, white and moonstone blue and one interior colour grey. There were also just two equipment options: with or without central locking and electric window lifts.Statement "most successful F1 engine in history" is not completely right. Cosworth as a company has supplied 67 Formula One teams with engines over the last 48 years. But most victorious F1 engine is Ferrari engine, whose engines have been behind and sometimes in front of Grand Prix-winning cars.
The first Ferrari engine victory was at the British GP. In this time more than units was produced. The only other engine with more than GP wins is Renault, withalthough Mercedes is closing in, currently with At the other end of the scale Porsche and Weslake engines have had one GP success apiece. Statistics are till the end of season Keith Duckworth and Mike Costin founded the company Cosworth in in a little shop with just the basics, like an engine stand, in Shaftsbury Mews, London, England.
The two Englishmen wrote their own success story for over 20 years before Cosworth was sold for the first time in to United Engineering Industries. However, both continued to be involved in the firm even when it changed hands again later.Mercruiser mefi
Inafter Duckworth's retirement, the Vickers Group took over the ownership and then, insold Cosworth Engineering to the Audi Groupwith a potentially dramatic effect on Ford's racing program, until the company was split in two: Cosworth Technology including the engineering, manufacturing and casting units stayed with the the Audi Group, while Ford Motor Company took control of Cosworth Racing and the company became works engine and electronics supplier to the Stewart Grand Prix Formula One team and its successor - Jaguar Racing.
Duckworth and Costin made the pages of motor sports history in openwheel, rally and closedwheel racing over the years. Their accomplishment in Formula One tops the charts.Fast house cap
The first assignment that the two new partners accepted after the founding of the new company was to develop parts for the Ford road car engines, concentrating on the Mk1 -- a modified 4-cylinder pushrod Ford E Anglia engine. Cosworth has had a long and distinguished career in Formula One, beginning in The 3. InDuckworth designed the DFV Double Four-Valve F1 engine on behalf of Ford Motor Company, at the time, he simply stated, "We are too small as a company to allow development and debugging to win over sound design.
DFV engine featured 32 valves operated by twin overhead camshafts driven by a train of 9 gears. The metering unit for the Lucas mechanical fuel injection was rotated by gear and belt from the inlet cam, while the exhaust cam drove an alternator on the rear of the head. This engine dominated Formula 1 untiland was also used in sports car racing in 1.
Walter Hayesthe public affairs director at Ford, in turn, offered the engine to Lotus, which had been stranded without competitive engine following the withdrawal of Coventry Climax after FIA changed to the three-litre formula for the season.
That three-litre V8 engine, which debuted inturned out to become the most successful Formula One engine of all time, winning their first race out of the box. During the s, it was common for almost the entire field with the notable exception of Ferrari to use one of these engines - this at a time when independent wealthy individuals could buy exactly the same engine off the shelf that was also being used by McLarenl. It won a record World Championship races, the last being Detroit inpowering a Tyrrell driven by Michele Alboreto.
#Tech – The Cosworth BD engine.
Running on "pump" gasoline, 's Cosworth DFV produced hp per liter. Astonishingly, the last Cosworth 3. DFV of set the pattern for the contemporary engine with its "supersquare" wider than higher cylinder dimensions, its pent-roof shape combustion chamber, its narrow included valve angle, its four valves per cylinder operated by double overhead camshafts and its clean porting.
The DFV was not radically different from previous engines, Its significance was that its detail design took advantage of the potential of four, rather than two valves per cylinder for enhanced breathing and burning - the fundamentals of effective combustion. Although the DFV did not produce as much power as some of its rival cylinder engines, it was lighter, resulting in a better power to weight ratio. In addition to being lighter, it was also made a structural part of the car itself, by placing load bearing arms to stress the block.Cosworth is a high performance engineering company.
It was founded in London in Cosworth is based in NorthamptonEngland. It also has a facility in PuneIndia. Cosworth has had a long and well respected career in Formula Onebeginning in Cosworth stepped away from Formula One for three years when no team decided to use their engines for The first Formula One engines shipped in January. The company was founded as a British racing internal combustion engine maker in by Mike Costin and Keith Duckworth  The name Cosworth came by combining their last names.
Even thought it was an independent company, it was supported by the Ford Motor Company for many years. Most of the Cosworth engines were named Ford engines. The company went through a several ownership changes. The business was growing. Keith Duckworth did not want to run the day-to-day business. He became a UEI board director.
UEI was a group of small to medium-sized technology companies. UEI was taken over by Carlton Communications in Carlton wanted some of the audio-visual companies that were part of UEI. Cosworth was a poor fit, so Carlton sold the Cosworth part off. InCosworth was sold to Vickers, a British engineering company.
InCosworth was sold to Audiwhich is a part of Volkswagen. The road car engine division of Cosworth was renamed Cosworth Technology. Cosworth has had a long relationship with the Ford Motor Company. This started when Cosworth started building racing engines in These engines were modified versions of the 1, cubic centimetres Cosworth built a 1, cubic centimetres It was used in Formula 3 when 1, cubic centimetres This was the dominate engine.
This engine featured dual overhead camshafts with 16 valves. This engine dominated the category until It was also used in sports car racing as the FVC. A larger engine was built for endurance racing in the mid s. The FVC displaced 1, cubic centimetres Cosworth solidified its association with Ford inby developing a double overhead camshaft DOHC valve inline four-cylinder engine for road use in the Ford Escort.
As the bore size reached ever closer to the bore center distance, leaving little space in between cylinders, the all three types had brazed-in cylinder liners to the block. As a departure from the Ford iron block, the BDG received a newly designed aluminium block soon after, and this cylinder block was used as a replacement part in rebuilding many other BD series engines as well as some Mk.
XIII engines. InFord asked Weslake and Co of Rye to build the BDD for them, and by the end ofthe production line was installed at Rye and production was under way. The Hart R and the Zakspeed F1 engines owe much to the BDA series, being essentially an aluminium-block derivative using similar heads. Toggle Navigation. Cosworth Engines Ford Engines.

The agreement between Ford and Cosworth was for the design and development, not the building of engines. Design started in May of and the first cc engine ran in June of When introduced it was the first British engine to use cogged belts to drive the camshafts.
In the BDB version was introduced. This was developed for Ford for use in the Escort RS for rallying. The bore was increased for a capacity of cc.Camera parts
Modifications were introduced by Cosworth and several other companies. The company continued to produce kits of parts to build up BD engines into the s. Cosworth increased its association with Ford inby developing a double overhead camshaft DOHC valve inline four-cylinder engine for road use in the Ford Escort.
Working from the Kent block, Cosworth created a 1, cc for homologation purposes. Running in Group 2 and Group 4 on either rallying or touring car racing, this engine could be enlarged to a maximum of 2, cc. The nominal homologation at 1, cc capacity meant that BDA-engined cars competed in what was usually the top class cc and up so were eligible for absolute victories rather than class wins.
In the BDG was introduced, it featured another increased cylinder capacity and produced bhp. The first versions had a cast iron block, but later engines had an aluminum block. The compression ratio was The cylinder numbering was 1 — 2 — 3 — 4 front to rear with a firing order of 1 — 3 — 4 — 2. I think you may be in error with respect to the statement that the BDA was the first UK belt drive production engine — the Vauxhall Slant-4 1.
Even before that was the or 2 Glas a German brand, later swallowed by BMW and that was the first production car implementation.
However, the construction of the Glas belt was different from the Uniroyal used by GM and upon which all subsequent belts have been based.
This was at cc and utilized a special Siamese bore cast iron block made specifically for racing by Ford.
I know…. I built many of them and all of the ones used by Mike the Bike. We spent a long time selecting the blocks by measuring the Siamese bore wall thicknesses to obtain the ones that had the best overall average wall thickness. Our cylinder heads were all modified in house by a great chap…Broddler Bill …. Brian was also the first to develop the alloy block for the BD using it initially in the 2Liter sports car series and it was designated Hart S This is not to be confused with the R which was a completely different engine with much bigger bores and bore spacing, longer than a BD We built all the Ford Escort factory rally engines and their team manager Peter Ashcroft was great friends with Brian and one evening Peter actually clipped his ankle on a covered block and what did he discover….
It was then discussions began and ultimately Ford bough the rights to the Hart Alloy BD block I was employed by Brian for almost 9 fantastic years.

Complete with electronic ignition Dyno time only.The name is an abbreviation of Double Four Valvethe engine being a V8 development of the earlier four-cylinder FVA, which had four valves per cylinder. For many years it was the dominant engine in Formula One, and it was also used in other categories of racing, including CARTFormula and sportscar racing.
The DFY variant had a revised bore and stroke of Up until that point, Colin Chapman 's successful Team Lotus cars had relied on power from fast revving Coventry Climax engines, but with the change in regulations Coventry Climax decided for business reasons not to develop a large capacity engine. Chapman then approached Ford of Britain's public relations chief, former journalist Walter Hayeswith whom he had developed a close working relationship from the early s.
Since Hayes had joined Ford in the pair had previously collaborated in the production of the successful Lotus Cortinaintroduced in The project was revealed by Hayes in a PR launch in Detroit at the end ofbut the engine was not ready until the third race of the season, on the 4 June at Zandvoort. Its debut proved successful.
Graham Hillwho was in the team at the specific request of Ford and Hayes,  put his DFV-powered Lotus 49 on pole position by half a second and led for the first 10 laps but was then sidelined by a broken gear in the camshaft drive. Team-mate Jim Clark moved up through the field in his identical car and came home to win. However, this dominant performance belied a serious fault in the timing gear. The progress of the engine was documented in a film produced by the Ford Motor Company's film section, entitled 9 Days in Summer.
Initially, the agreement between Ford, Cosworth and Lotus was binding on all parties, and Ford as the funder had no plans to sell or hire the DFV to any other teams. However, it occurred to Hayes that there was no competition: the Ferrari engine was underpowered; the BRM complex and too heavy; the Maserati unreliable; the Honda overweight; while Dan Gurney 's Weslake motor was powerful but unreliable.
Hayes concluded that Ford's name could become tarnished if the Lotus were to continue winning against only lesser opposition, and that they should agree to use the unit in other teams, and hence potentially dominate Formula One. At the end ofCopp and Hayes gently explained to Chapman that he would no longer have monopoly use of the DFV and in August it was announced that the power unit would be available for sale, via Cosworth Engineering, to racing teams throughout the world.
In and every World Championship race was won by DFV-powered cars, with the engine taking a total of wins from races between and The advent of ground effect aerodynamics on the F1 scene in provided a new lease of life for the now decade-old engine.16 wooden spoon
The principle relied on Venturi tunnels on the underside of the car to create low pressure regions and thus additional downforce. Previously, teams running Ferrari and Alfa-Romeo flat engines had enjoyed a handling advantage due to the low centre of gravity in such a configuration.
However, for ground effect, the wide engine was completely the opposite of what was required as the cylinder heads protruded into the area where the Venturi tunnels should have been. In contrast, the V-configuration of the Cosworth engine angled the cylinders upwards and left ample space under the car for the necessary under-body profile  which massively increased downforce and gave more efficient aero balance, thus increasing cornering potential and straight line speed.
The onset of the turbo era in the early s put an end to the DFV's F1 activities, as even with modifications the year-old engine could not hope to compete with the vast power being put out by the new 1.In alto adige test covid per turisti e personale
