All wankel engines Mazdarotary enginerotary engines are essentially a single family - they all derive from the firstrotary engineexperiments in the early 1960srotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesOver the years, displacement has been increased (somewhat) wankel engines , and turbocharging has been added to great effect rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThis is the engine family that made Mazdafamousrotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
In auto racingand for Japanese tax purposes, the displacement of rotary wankel engines engine engines is defined as the equivalent of 1.5 times the nominal displacementrotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesSo the 1.3 L 13B engines count as just under 2.0 L for these purposes rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
rotary enginewankel engines engines can be classified by their rotor size in terms of width (diameter) and depth (thickness)rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThese metrics function similarly to the bore and stroke measurements of a piston engine rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engineswankel engines Nearly all Mazdaproductionrotary engineengines share a single rotor diameter: 105 mm (4.1 in) with a 15 mm (0.6 in) crankshaft offsetrotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThe only engine to diverge from this formula wankel engines was the rare 13A, which used a 120 mm (4.7 in) diameter and 17.5 mm (0.7 in) offset rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
40A
Mazda's first prototyperotary enginewas the 40A, a single-rotor engine wankel engines very much like the NSU KKM400rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesAlthough never produced in volume, the 40A was a valuable testbed for Mazdaengineers, and quickly demonstrated two serious challenges to the feasibility of the design: wankel engines chatter marks in the housing and heavy oil consumptionrotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThe chatter marks, nicknamed devil's fingernails, were caused by improper sealing at the apex of the rotor rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThe oil consumption problem was wankel engines addressed with heat-resistant rubber oil seals at the sides of the rotors rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThis early engine had a rotor diameter of 90 mm (3.5 in) , an offset of 14 mm (0.6 in) wankel engines , and a depth of 59 mm (2.3 in) rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
L8A The very first MazdaCosmo prototype used a 798 cc L8A two-rotorrotary enginerotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThe engine and car wankel engines were both shown at the 1963 Tokyo Motor Show rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesHollow cast iron apex seals reduced vibration and thus chatter marks rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesIt used dry-sump lubrication rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesRotor diameter was up from the wankel engines 40A to 98 mm (3.9 in) , but depth dropped to 56 mm (2.2 in) rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
One-, three-, and four-rotor derivatives of the L8A were also created for experimentation rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
wankel engines 10A The 10A series was Mazda's first productionrotary engine, appearing in 1965rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesIt was a two-rotor design, with each displacing 491 cc for a total of 982 cc rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThese wankel engines engine featured the mainstream rotor dimensions with a 60 mm (2.4 in) depth rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
The rotor housing was made of sand-cast aluminum plated with chrome, while the aluminum sides were sprayed with wankel engines molten carbon steel for strength rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesCast iron was used for the rotors themselves, and their eccentric shafts were of expensive chrome-molybdenum steel rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThe addition of aluminum/carbon apex seals addressed the chatter wankel engines mark problem rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
0810 The first 10A engine was the 0810, used in the Series I Cosmo from May, 1965 through July, 1968 rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThese cars, and their revolutionary engine, were wankel engines often called L10A modelsrotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesGross output was 110 hp (82 kW) at 7000 RPM and 130 Nm (96 ft.lbf) at 3500 RPM, but both numbers were probably optimistic rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
The 10A wankel engines featured twin side intake ports per rotor, each fed by a one of four carburetor barrels rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesOnly one port per rotor was used under low loads for added fuel economy rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesA wankel engines 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 rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesA bit of oil was wankel engines mixed with the intake charge for lubrication rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary engines
The 0810 was modified for the racing Cosmos used at Nürburgring rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesThese engines had both side- and peripheral-located intake ports switched with a wankel engines butterfly valve for low- and high-RPM use (respectively) rotary engine, wankel engines, wankel rotary, wankelrotary engine, wankelrotary enginesBy: Jon beal |
