All onmouseover="pv(event, 73)" onmouseout="unpv(73)" style="">Mazda Wankel "rotary" engines are essentially a single family - they all derive from the first Wankel experiments in the early 1960s. Over the years, displacement has been increased (somewhat), and turbocharging has been added to great effect. This is the engine family that made Mazda famous.

Prof. ...

In auto racing, the displacement of a Wankel engine is usually doubled for classing purposes. For Japanese tax purposes, the displacement of Wankel engines is defined as the equivalent of 1.5 times the nominal displacement. So the 1.3 L 13B engines count as just under 2.0 L for these purposes. Auto racing (also known as automobile racing, autosport or motorsport) is a psuedo-sport involving racing automobiles. ...

Wankel engines can be classified by their rotor size in terms of width (diameter) and depth (thickness). These metrics function similarly to the bore and stroke measurements of a piston engine. Nearly all Mazda production Wankel engines share a single rotor diameter: 105 mm (4.1 in) with a 15 mm (0.6 in) crankshaft offset. The only engine to diverge from this formula was the rare 13A, which used a 120 mm (4.7 in) diameter and 17.5 mm (0.7 in) offset. Engine displacement is defined as the total volume of air/fuel mixture an engine can draw in during one complete engine cycle; it is normally stated in cubic centimetres, litres or cubic inches. ...

40A

Mazda's first prototype Wankel was the 40A, a single-rotor engine very much like the NSU KKM400. Although never produced in volume, the 40A was a valuable testbed for Mazda engineers, and quickly demonstrated two serious challenges to the feasibility of the design: "chatter marks" in the housing, and heavy oil consumption. The chatter marks, nicknamed "devil's fingernails", were caused by improper sealing at the apex of the rotor. The oil consumption problem was addressed with heat-resistant rubber oil seals at the sides of the rotors. This early engine had a rotor diameter of 90 mm (3.5 in), an offset of 14 mm (0.6 in), and a depth of 59 mm (2.3 in). Wikipedia does not yet have an article with this exact name. ...

L8A

The very first Mazda Cosmo prototype used a 798 cc L8A two-rotor Wankel. The engine and car were both shown at the 1963 Tokyo Motor Show. Hollow cast iron apex seals reduced vibration and thus chatter marks. It used dry-sump lubrication. Rotor diameter was up from the 40A to 98 mm (3.9 in), but depth dropped to 56 mm (2.2 in).

The Tokyo Motor Show is an annual auto show held in November in Tokyo, Japan. ... A dry sump is a lubricating oil managment method for four-stroke and large two-stroke piston internal combustion engines that uses a secondary reservoir for oil, as compared to a conventional wet sump system. ...

One-, three-, and four-rotor derivatives of the L8A were also created for experimentation.

10A

The 10A series was Mazda's first production Wankel, appearing in 1965. It was a two-rotor design, with each displacing 491 cc for a total of 982 cc. These engine featured the mainstream rotor dimensions with a 60 mm (2.4 in) depth. 1965 (MCMLXV) was a common year starting on Friday (the link is to a full 1965 calendar). ...

The rotor housing was made of sand-cast aluminum plated with chrome, while the aluminum sides were sprayed with molten carbon steel for strength. Cast iron was used for the rotors themselves, and their eccentric shafts were of expensive chrome-molybdenum steel. The addition of aluminum/carbon apex seals addressed the chatter mark problem.

0810

The first 10A engine was the 0810, used in the Series I Cosmo from May, 1965 through July, 1968. These cars, and their revolutionary engine, were often called L10A models. Gross output was 110 hp (82 kW) at 7000 RPM and 130 Nm (96 ft.lbf) at 3500 RPM, but both numbers were probably optimistic. Wikimedia Commons has media related to: Mazda Cosmo There have been 4- generations Mazda automobiles named Mazda Cosmo. ... 1968 (MCMLXVIII) was a leap year starting on Monday (the link is to a full 1968 calendar). ...

The 10A featured twin side intake ports per rotor, each fed by a one of four carburetor barrels. Only one port per rotor was used under low loads for added fuel economy. A single peripheral exhaust port routed hot gas through the coolest parts of the housing, and engine coolant flowed axially rather than the radial flow used by NSU. A bit of oil was mixed with the intake charge for lubrication. Stromberg side-draft carburetor The carburetor, carburettor, or carburetter (see spelling differences), also called carb (in North America) or carbie (chiefly in Australia) for short, is a device that mixes air and fuel for an internal-combustion engine. ...

The 0810 was modified for the racing Cosmos used at Nürburgring. These engines had both side- and peripheral-located intake ports switched with a butterfly valve for low- and high-RPM use (respectively) Wikimedia Commons has media related to: Mazda Cosmo There have been 4- generations Mazda automobiles named Mazda Cosmo. ...

0813

The improved 0813 engine appeared in July, 1968 in the Series II/L10B Cosmo. Its construction was very similar to the 0810, but the ports and carburetion were revised to produce 128 hp (96 kW) at 7000 RPM and 140 Nm (103 ft.lbf) at 5000 RPM. Again, these were Japanese net output figures. 1968 (MCMLXVIII) was a leap year starting on Monday (the link is to a full 1968 calendar). ...

0820

The 10A was substantially revised for wide-scale production in the R100/Familia Rotary. Many changes were made in an effort to reduce production costs. These included the use of cast iron in the housing sides, less-expensive molded (instead of sand-cast) aluminum for the housings, and chrome-steel for the eccentric shafts. The port arrangement remained the same, but exhaust was no longer routed around the housing. The Mazda R100 used the chassis from the Familia and the rotary 0820 engine similar to the one used in the Cosmo Sport Series II. It was a 2 door 2+2 coupe and was produced from 1968 to 1973. ...

Japanese-spec gross output was 100 hp (75 kW) at 7000 RPM and 98 ft.lbf (133 Nm) at 3500 RPM. The use of less-expensive components raised the weight of the engine from 224 lb (102 kg) to 268 lb (122 kg).

0866

The final member of the 10A family was the 1971 0866. This variant featured a cast-iron thermal reactor to reduce exhaust emissions and re-tuned exhaust ports. The die-cast rotor housing was now coated with a new process: The new Transplant Coating Process (TCP) featured sprayed-on steel which is then coated with chrome. Gross output was 105 hp (78 kW) at 7000 RPM and 135 Nm (99.5 ft.lbf) at 3500 RPM. 1971 (MCMLXXI) was a common year starting on Friday (the link is to a full 1971 calendar). ...

13A

The 13A was designed especially for front wheel drive applications. It had two 655 cc rotors for a total of 1310 cc. This was the only production Mazda Wankel with different rotor dimensions: Diameter was 120 mm (4.7 in) and offset was 17.5 mm (0.7 in), but depth remained the same as the 10A at 60 mm (2.4 in). Another major difference from the previous engines was the integrated water-cooled oil cooler. Front wheel drive is the most common form of engine/transmission layout used in modern passenger cars, where the engine drives the front wheels. ...

The 13A was used only in the 1969-1972 R130 Luce, where it produced 126 hp (94 kW) and 126 ft.lbf (172 Nm). This was the end of the line for this engine design: The next Luce was rear wheel drive and Mazda never again made a front wheel drive rotary vehicle. 1969 (MCMLXIX) was a common year starting on Wednesday (the link is to a full 1969 calendar). ... 1972 (MCMLXXII) was a leap year starting on Saturday. ... Mazda used the Luce name on its largest sedans in Japan from 1969 until 1989. ... Rear wheel drive was a common form of engine/transmission layout used in automobiles throughout the 20th century. ...

12A

The 12A was a "bored-out" version of the 10A - the rotor diameter was the same, but the depth was increased by 10 mm (0.4 in) to 70 mm (2.8 in). Each of its two rotors displaced 573 cc for a total of 1146 cc. The 12A series was produced for 15 years, from May 1970 through 1985. In 1974, a 12A became the first engine built outside of western Europe or the U.S to finish the 24 hours of Le Mans. 1970 (MCMLXX) was a common year starting on Thursday (the link is to a full 1970 calendar). ... This article is about the year. ... 1974 (MCMLXXIV) was a common year starting on Tuesday. ... To meet Wikipedias quality standards, this article or section may require cleanup. ...

In 1974, a new process was used to harden the rotor housing. The Sheet-metal Insert Process (SIP) used a sheet of steel much like a conventional piston engine cylinder liner with a chrome plated surface. The side housing coating was also changed to eliminate the troublesome sprayed metal. The new "REST" process created such a strong housing, the old carbon seals could be abandoned in favor of conventional cast iron. 1974 (MCMLXXIV) was a common year starting on Tuesday. ...

Early 12A engines also feature a thermal reactor, similar to the 0866 10A, and some use an exhaust port insert to reduce exhaust noise. A lean-burn version was introduced in 1979 (in Japan) and 1980 (in America) which substituted a more-conventional catalytic converter for this "afterburner". A major modification of the 12A architecture was the 6PI which featured variable induction ports. Catalytic converter on a Saab 9-5. ...

Turbo

The ultimate 12A engine was the turbocharged and fuel injected engine used in the Japan-spec Cosmo, Luce, and RX-7. It featured "semi-direct injection" into both rotors at once, a technique that was much more successful than it would appear. A passive knock sensor was used to eliminate detonation, and later models featured a specially-designed "impact turbo" which was tweaked for the unique exhaust signature of the Wankel engine.

The Mazda RX-2 was a midsize car introduced in 1970 and sold through 1978. ... The Mazda RX-3 was an automobile sold in the 1970s. ...

13B

The 13B is the most widely-produced engine. It was the basis for all future Mazda Wankel engines, and was produced for almost 30 years. The 13B is no relation to the 13A. Instead, it is a lengthened version of the 12A, having 80 mm (3.1 in) thick rotors. It had the largest displacement yet at 654 cc, for a total of 1308 cc.

In the United States, the 13B was available from 1974 through 1978 and was then retired until the 1984 RX-7 GSL-SE. It was retired again in 1996 with the cancellation of the RX-7. The engine was continually used in Japan from 1972's Mazda Luce/RX-4 through 2002's RX-7. 1972 (MCMLXXII) was a leap year starting on Saturday. ...

13B-RESI

A tuned intake manifold was used in a Wankel engine for the first time with the 13B-RESI ("Rotary Engine Super Injection"). The so-called Dynamic Effect Intake featured a two-level intake box which derived a supercharger-like effect from the Helmholtz resonance of the opening and closing intake ports. The RESI engine also featured Bosch L-Jetronic fuel injection. Output was much improved at 135 hp (101 kW) and 133 ft·lbf (180 N·m).

13B-DEI

Like the 12A-SPI, the second-generation RX-7 bowed with a variable-intake system. Dubbed DEI, the engine features both the 6PI and DEI systems, as well as four-injector electronic fuel injection. Total output is up to 146 hp (109 kW) at 6500 rpm and 138 ft·lbf (187 N·m) at 3500 rpm. The examples and perspective in this article or section may not represent a worldwide view. ...

13B-Turbo

The 13B-DEI was turbocharged in 1987. It features the newer four-injector fuel injection of the 6PI engine, but lacks that engine's eponymous variable intake system. The twin-scroll turbocharger is fed with a two-stage valve to reduce turbo lag. Output is way up at 185 hp (138 kW) at 6500 rpm and 183 ft·lbf (248 N·m) at 3500 rpm.

13B-REW

A twin-turbocharged version of the 13B, the 13B-REW, became famous for its high output and low weight. The twin Hitachi HT-12 turbos were operated sequentially, with the primary providing boost until 4,500 RPM, and the secondary coming online afterwards. Output eventually reached, and may have exceeded, Japan's "maximum" of 280 hp (208 kW) for the final revision used in the series 8 Mazda RX-7.

13B-MSP RENESIS

The RENESISwas an evolution of the 13B and first appeared (in production) in the 2004 Mazda RX-8. The Renesis 13B is very different from any other Wankel for two reasons: First, the exhaust ports are no longer located on the rotor housing (the only other rotary ever to do this was the 10A), and the rotors are shaped differently. The MSP designation thus stands for multi-sideport. The rotors have grooves cut along the sides to prevent timing overlap. With a 13B engine, certain companies such as CTS Racing made super lightweight racing rotors with similar features. The naturally aspirated RENESIS produces 232hp @ 8500 RPM with a 9000 RPM redline (Mazda originally reported 250hp, but dyno tests have proven otherwise - compare this to 255hp (190 kW) for the twin turbocharged 13B in the Mazda RX-7.

Mazda was fully committed to the Wankel engine just as the energy crisis of the 1970s struck. The company had all but eliminated piston engines from its products in 1974, a decision that nearly led to the company's collapse. A switch to a three-prong approach (gasoline, Diesel, and Wankel) for the 1980s relegated the Wankel to sports car use (in the RX-7 and Cosmo), severely limiting production volume. But the company has continued production continually since the mid-1960s, and is the only maker of Wankel-powered cars (the RX-8) today.

Though not reflected in the graph at right, the RX-8 is a higher-volume car than its predecessors, and Mazda is considering adding more Wankel models. The company has also developed a hydrogen-powered version of the Renesis. Though sales leveled off in the 1990s, these factors could cause the Wankel to again be a substantial force in the automotive market.
