Although it is relatively easy to derive a 90 ° V6 from an existing V8 design by simply cutting two cylinders off the engine, this tends to make it wider and more vibration-prone than a 60 ° V6.

Although many manufacturers licensed the design, including Citroën with their M35 and GS Birotor, using engines produced by Comotor, General Motors, which seems to have concluded that the Wankel engine was slightly more expensive to build than an equivalent reciprocating engine, although claiming having solved the fuel economy issue, but failed in obtaining acceptable exhaust emissions, and Mercedes-Benz which used it for their C111 concept car, only Mazda has produced Wankel engines in large numbers.

Although in two dimensions the seal system of a Wankel looks to be even simpler than that of a corresponding multi-cylinder piston engine, in three dimensions the opposite is true.

Although engineering studies of all of these designs were made, only the solid-core engine was ever built.

Although he also developed a type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft.

Although it was the popularity of the Oldsmobile division vehicles that prompted this change, declining sales of V8 engines would have made this change inevitable as all but the Chevrolet version of the 350-cubic-inch engine were eventually dropped.

Although it was only fractionally longer than the contemporary Volkswagen Beetle, Time said the length of its hood over the front-mounted engine made " the difference seem considerably more ", adding that the car " resembles a sawed-off station wagon, with a long, low hood and swept-up rear, and is faintly reminiscent of the original Studebaker Avanti.

Although it was to be several years before Bristol showed any profit from the aero engine division, the Jupiter engine eventually proved enormously successful: indeed, during the inter-war period the aero-engine division was more successful than the parent company and Bristol came to dominate the market for air-cooled radial engines.

Although a small car, the engine has great elasticity and gave the feeling of better output than its small nominal size.

Although cocoa is originally from the Americas, today Western Africa produces almost two-thirds of the world's cocoa, with Côte d ' Ivoire growing almost half of it.

Although much has been made of its status as a major exporter of oil, Nigeria produces only about 2. 7 % of the world's supply.

Although oxidative phosphorylation is a vital part of metabolism, it produces reactive oxygen species such as superoxide and hydrogen peroxide, which lead to propagation of free radicals, damaging cells and contributing to disease and, possibly, aging ( senescence ).

Although modern steelmaking processes negate the need to blend different steels, pattern welded steel is still used by custom knifemakers for the cosmetic effects it produces.

Although the proteasome normally produces very short peptide fragments, in some cases these products are themselves biologically active and functional molecules.

Although constitutively expressed proteasomes can participate in this process, a specialized complex composed of proteins whose expression is induced by interferon gamma produces peptides of the optimal size and composition for MHC binding.

Although the Sun produces Gamma rays as a result of the nuclear fusion process, these super high energy photons are converted to lower energy photons before they reach the Sun's surface and are emitted out into space.

Although there are only static electric and magnetic fields, the calculation of the Poynting vector produces a clockwise circular flow of electromagnetic energy, with no beginning or end.

Although the Hanna-Barbera name remains on the copyright notices of new productions based on " classic " properties like the Flintstones, the Jetsons and others, the studio that produces these works is Warner Bros.

Although incapacitation may result from physiological changes such as mucous membrane irritation, diarrhea, or hyperthermia, the term " incapacitating agent " as militarily defined refers to a compound that produces temporary and nonlethal impairment of military performance by virtue of its psychobehavioral or CNS effects.

Although differential hardening produces a very hard edge, it also leaves the rest of the sword rather soft, which can make it prone to bending under heavy loads, such as parrying a hard blow.

Although Scotland sustains approximately 90 distilleries, Ireland has only four ( although each produces a number of different whiskeys ): economic difficulties in the last few centuries have led to a great number of mergers and closures.

Although fewer by-products are formed by ozonation, it has been discovered that ozone reacts with bromide ions in water to produces concentrations of the suspected carcinogen bromate.

Although his wage seems to be based on hours worked, in an economic sense this wage does not reflect the full value of what the worker produces.

Although the most common isotope of uranium, uranium-238 (< sup > 238 </ sup > U ), can be used as secondary fissionable material in hydrogen bombs, it cannot be used as the primary fissile material for an atomic bomb .< sup > 238 </ sup > U can be used to produce < sup > 239 </ sup > Pu, through the fission of < sup > 235 </ sup > U which produces neutrons, some of which will be absorbed by < sup > 238 </ sup > U creating < sup > 239 </ sup > U. After a few days the < sup > 239 </ sup > U will decay, turning into weapons-usable < sup > 239 </ sup > Pu.
