The Mazda Rotary Engine Part 2

Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the Rotary engine works with comparisons to the Piston Engine. Also shows the Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or 110S). Originates from the late 60's.

My dad owns a 2009 mazda rx8 and it says in the handbook U MUST CHECK THE OIL LEVELS EVERY 3 PETROL STOPS witch is every 4 days for him. why do they use so much oil?

[djphilmanns]

@arrancooper69

it's the way rotary engines work, oil is injected diectly into the rotor housings for lubrication in the mazda engines and is burnt with the fuel. in the nsu engines it's mixed into the fuel feed by an oil metering pump. they don't actually use that much oil, but it's very important to keep it topped up to the max! :)

the rotary would have been way more efficient today if ford didn't buy half of mazda and made them build a bunch of piston engines... now mazda is back on its own two feet and now we will see much change in the rotary industry

@UAE224455 It never had. The 13B engine (as delivered with the FC3S and FD3S) has 2 rotors, while RX-7s with 3-rotor engines will have had an engine swap (probably 20B) from larger, heavier cars. They were never sold with the 20B engine, though.

@Jutzujin so funny that my friend's Turbo 2 has over 150K on it and it's still running strong. and my own NA has 210 on ODO and it's still getting normal compression readings.

if u don't know shit that's ok, but don't comment on things u know nothing about. Thx.

My God I want an RX-8 so bad!!!

@bboyhwoarang The Mazda Rx7 has 3 Rotors

[manolo44op]

how many parts a rotary engine needs to be compare to a 2jzgte engine? ;) maybe 6 rotors xD

[stealthlol266]

@bboyhwoarang

Around 2-4 rotors

[bboyhwoarang]

how many rotors or that triagle thingy are in one rotary engine?

[woggleboggle123]

@Alex35J simply because they wear down more quickly. dunno about being more complicated as such but you burn a lot more oil and have to replace things much more often then with a piston.

Rotaries are great in terms of getting a large amount of power in proportion to the displacement of the unit, a 2 "cylinder" rotary engine can put out as much as a 4 cylinder piston engine but obviously at a cost; that being quicker wear, lots of oil burned for lubrication and poor fuel economy.

[Alex35J]

than do they say that its more complicated and expensive to fix rotary engine problems???? cuz im thinking bout gettting an RX8 but everybodys telling me that their hard to fix and cost more money 

[Jutzujin]

A spirited driver in a rotary powered vehicle will most likely experience engine failure at around 70-80 thousand miles, while piston engines can operate effectively after 250 thousand miles. Diesel engines can double or even triple that, some still running on original parts for over a million miles. That's why the Rotary engine hasn't replaced anything. The piston engine is more efficient, gets better gas mileage, makes more torque, and doesn't require 9000rpm to make the torque of a 4 cyl.
