Oil System Modifications | Rotary Engine Specialists | Mazda ...

Mazda factory engines are equipped with a device located in the front of the E-shaft called a "Thermopellet." It is a type of valve or thermostat which allows the engine oil which cools the rotors to bypass the rotors while the vehicle is warming up.

This reduces flex in the e-shaft at high rpm's thus enabling the rotor clearances to be set at minimum and seal clearances to be tighter. This means more horsepower. And it's 2.6 lbs lighter than the stock Mazda eccentric shaft, which means quicker rev's and less stress.

For most purposes, there are only two choices of rotor bearings (technically, there are other models for the 13G 3-rotor, and to fit a 13G rotor to a 13B eccentric shaft, but these are relatively rare). Both 12A and 13B rotors use the same bearing. The two choices are the stock bearing and the MFR bearing.

Mazda Wankel engine - Wikipedia

Displacement is 3 √ 3 radius·offset·depth, multiplied with the number of rotors (note that this only counts a single face of each rotor as the entire rotor's displacement, because with the eccentric shaft – crankshaft – spinning at three times the rate of the rotor, only one power stroke is created per output revolution, thus only one face of the rotor is actually working per "crankshaft" revolution, roughly equivalent to a 2-stroke engine of similar displacement to ONE rotor face).

How the elusive 4-rotor rotary engine works

Nov 28, 2016 · A 3-rotor engine places the rotors 120 degrees apart. And the 4-rotor? On the eccentric shaft, rotors 1 and 2 sit at a 180-degree angle to each other, and so do rotors 3 and 4, though 3 and 4 are ...

Engine revolution: Mazda's rotary and its uncertain future ...

A 2:3 gear ratio yields three full turns of the eccentric shaft for every 360 degrees of rotor motion. To visualize the overall kinesis, think hula hoop: rotor spin compounded by eccentric-shaft rotation. The moving rotor's apexes define a path called an epitrochoid. (Google this word for an extra helping of confusion.)

The main bearing-to-eccentric shaft clearance should be .003" +/- .0005" for operation at less than 8,500 RPM; if the engine will exceed 8,500 RPM, proper clearance is .004" +/- .00025". In addition, bear in mind that as power, rotor weight and/or RPM increase, so should bearing clearance.
