Daimler Double-Six may refer to either of two different series of Daimler V12 engines or to a car produced by Jaguar Cars under the Daimler nameplate.
The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre–World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling, and the Knight system double sleeve engine's tendency to burn a lot of lubricating oil or to seize due to lack of it. The Scottish Argyll company used its own, much simpler and more efficient, single sleeve system (Burt-McCollum) in its cars, a system which, after extensive development, saw substantial use in British aircraft engines of the 1940s, such as the Napier Sabre, Bristol Hercules, Centaurus, and the promising but never mass-produced Rolls-Royce Crecy, only to be supplanted by the jet engines.
The inline-six engine is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders.
The Daimler Company Limited, before 1910 known as the Daimler Motor Company Limited, was an independent British motor vehicle manufacturer founded in London by H. J. Lawson in 1896, which set up its manufacturing base in Coventry. The company bought the right to the use of the Daimler name simultaneously from Gottlieb Daimler and Daimler-Motoren-Gesellschaft of Cannstatt, Germany. After early financial difficulty and a reorganisation of the company in 1904, the Daimler Motor Company was purchased by Birmingham Small Arms Company (BSA) in 1910, which also made cars under its own name before the Second World War. In 1933, BSA bought the Lanchester Motor Company and made it a subsidiary of the Daimler Company.
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.
The Jaguar XJ is a series of mid-size/full-size luxury cars produced by British automobile manufacturer Jaguar Cars from 1968 to 2019. It was produced across five basic platform generations with various updated derivatives of each. From 1970, it was Jaguar's flagship four-door model. The original model was the last Jaguar saloon to have been designed under the leadership of Sir William Lyons, the company's founder, and the model has been featured in countless media and high-profile appearances.
An evolution of the 1964 DOHC prototype “XJ13” engine, the Jaguar V12 engine is a family of SOHC internal combustion V12 engines with a common block design, that were mass-produced by Jaguar Cars for a quarter of a century, from 1971 to 1997, mostly as 5.3‑litres, but later also as 6‑litres, and 7‑litre versions that were deployed in racing. Except for a few low-volume exotic sports car makers, Jaguar's V12 engine was the world's first V12 engine in mass-production. For 17 years, Jaguar was the only company in the world consistently producing luxury four-door saloons with a V12 engine. The V12 powered all three series of the original Jaguar XJ luxury saloons, as well as its second generation XJ40 and X305 successors.
The Lanchester Motor Company Limited was a British car manufacturer in active trade between 1899 and 1955. Though the Lanchester Motor Company Limited is still registered as an active company and accounts are filed each year, the marque has been dormant since. As of 2014 it is marked as "non-trading".
Sydney Charles Houghton "Sammy" Davis was a British racing motorist, journalist, graphic artist and clubman.
The Mercedes-Benz R129 SL is a roadster which was produced by Mercedes-Benz from 1988 until 2001. The R129 replaced the R107 in 1989 and was in its turn replaced by the R230 SL-Class in 2002 for the 2003 model year.
The Mercedes-Benz M104 is a automobile straight-six engine produced from 1988 through 1999. It has a double overhead cam design with 4 valves per cylinder, and used a crossflow cylinder head. It replaced the M103 and was replaced by the M112 V6 starting in 1997. The bore spacing on all M104 engines is the same as M103 engines.
The Mercedes-Benz W140 is a series of flagship vehicles manufactured by Mercedes-Benz from 1991 to 1998 in sedan/saloon and coupe body styles and two wheelbase lengths. Mercedes-Benz unveiled the W140 S-Class at Geneva International Motor Show in March 1991, with the sales starting in April 1991 and North American launch was on 6 August 1991.
The Knight engine is an internal combustion engine, designed by American Charles Yale Knight (1868-1940), that uses sleeve valves instead of the more common poppet valve construction.
Daimler V-8 engines were designed for the Daimler Company by Edward Turner and produced from 1959 to 1969. Initially used in the SP250 sports car and the Majestic Major saloon, the engine was mostly used in the Daimler 2.5 V8 saloon made with Jaguar Mark 2 unit bodies from 1962 to 1969. Approximately 20,000 of the 2.5-litre version of the engine were made for use in the SP250 and the 250 saloon, while approximately 2,000 of the 4.5-litre version were made for use in the Majestic Major saloon and its limousine variant which remained in production until 1968.
The Volvo 900 Series is a range of executive cars produced by the Swedish manufacturer Volvo Cars from 1990 to 1998. The 900 Series was introduced in 1990 to replace the 700 Series from which it derived. Prior to the end of its production, the 960 was renamed as the Volvo S90 (saloon) and Volvo V90 (estate), and the 940 was renamed 940 Classic, becoming the last rear-wheel-drive cars from Volvo, until the 2023 Volvo XC40.
Daimler Sovereign was a name applied by British manufacturer Jaguar Cars to a sequence of luxury automobiles built by it but carrying the Daimler badge between 1966 and 1983.
Laurence Henry Pomeroy (1883–1941) was an English automotive engineer trained as a locomotive engineer and particularly interested in the introduction of light alloys into automotive applications.
The Daimler Fifteen was a saloon car at the low end of Daimler Company’s range, offered between 1932 and 1937. It was the first Daimler product for more than two decades with an engine that breathed conventionally through poppet valves. Conventional valve gear had improved, superseding the former advantages of the Daimler-Knight sleeve-valve technology. The car's name derived from its tax rating of 15 hp. The design of its 6-cylinder 1.8-litre engine was developed from the 4-cylinder 1.2-litre Lanchester Ten which was installed in Lanchester's shorter versions of the same chassis and bodies and using the same Daimler semi-automatic transmissions.
The Daimler Double-Six sleeve-valve V12 was a piston engine manufactured by The Daimler Company Limited of Coventry, England between 1926 and 1938. It was offered in four different sizes for their flagship cars.
Daimler Straight-Eight engines were eight-cylinder in-line petrol engines made by the Daimler Company to power the largest and most expensive cars in their range. The Straight-Eight engines replaced Daimler's earlier Double-Six V12 engines. Unlike the Double-Six engines, which used sleeve valves based on the Knight patents, the Straight-Eights used conventional poppet valves in the overhead valve configuration.
