The Wankel Engine
The Wankel Engine has been said to be similar to the MYT Engine by some people. The Wankel engine has very few parts and is a rotary engine. I don’t see any how the
Wankel engine can be compared to the MYT Motor, but I am not an engineer or a inventor.
How the Wankel Rotary Engine works
I think the MYT Engine is a new green invention for our future and I believe will be more fuel efficient and have lower emissions. The MYT motor is fully scalable and
has the highest power to weight ratio of any engine in production today.
The MYT Engine is the only engine in the world that can supply high volume, high flow and high pressure all at the same time.
How Rotary Engines Work – Mazda RX-7 Wankel – Detailed Explanation
In this video we’ll be talking about how rotary engines work.
In front of me I have a thirteen be Wankel engine out of a 1985 Mazda rx7.
We will be talking about all of the different components in here.
We will be talking about how the combustion cycle works. From there we’ll talk about some of the different unique features on this engine. Then we will get into the advantages of this design.
Starting on the right here and then working your way across. This is the front plate here we have the rotor housing for the first rotor. We’ve got the centre-plate, the second rotor housing, and then the rear plate.
The 13 B is a two rotor design, so here we have the two rotors. These are the rotary equivalent of distance. Finally we have what is called the eccentric shaft. This is essentially the crankshaft but for a rotary engine.
This is where your two rotors are gonna be connected up to, and ultimately trying to rotate.
we are going to be getting into how combustion works now. We’re gonna be looking inside of this rotor housing. What we have here are the intake ports.
As the rotor rotates over this it’s gonna be drawing a vacuum pulling air out from these ports.
It is important to realise that there are ports on both sides. Both the back plate and the centre-plate have ports.
So air will be drawn in from both sides into the combustion chamber. Moving right along here you have the two holes for your spark plugs. There’s gonna be two spark plugs used.
As that rotor rotates it will press the gas flow through the exhaust port. You can see it here, so now we will work our way through the 4 cycles, which need to occur for combustion.
First we’re going to be starting without any pockets, so that you can see the rotors completely.
As it begins to rotate, it starts to open up a pocket and this creates a vacuum. As it continues to rotate that vacuum opens up to the intake ports. This allows you to draw in air, and fuel. It continues to rotate, and then eventually you start to fill up this entire chamber. Then you close off the intake ports, and now you’ve begun compression.
Now this chamber is going to start squeezing down that air, and fuel mixture, into a smaller chamber. It does that until it reaches the equivalent of top dead centre which is about here.
You can see you’ve got this really small pocket and so now you’re to spark plugs are going to fire into. So, to continue to rotate and combust, is going to force this rotor to rotate in this direction as you can see. It will continue expanding that pocket and then finally you will open up to the exhaust port. It is at the exhaust port where that exhaustion when dumped out in the rotor, continues to rotate. At the same time, it is, forcing out all of that exhaust.
This cycle repeats itself. So, looking on the side of the engine you can see the intake ports so in the centre for the centre-plate it’s going to divide between them. This will go to the rear housing and then this one will go to the front housing. Then you’ve got these two intake ports, one on either side, which will also feed into these rotor housings.
As you continue down, you’ve got the exhaust port. For each housing, it’s important to realise, that at any moment within this rotor housing you have multiple stages of combustion occurring so you’ve got the initial cycle.
Right here we’ve got the intake. That means that you’ve got compression happening right here. You’ve got your exhaust stroke occurring right here.
All of these can be happening almost simultaneously when the rotor is in this position after your to continue to rotate it. You’re gonna be having your spark!
They’re going to have the exhaust, and here you’re going to be having your intake stroke as you continue to rotate that rotor.
You can see combustion dickering, and we have our exhaust occurring, followed by starting to exit the intake stroke, and the necessary start to get into the compression stroke.
When the rotors in this position here we have our compression occurring. Here we have our combustion and the exhaust is finishing up and then the intake is just beginning.
Now, it’s also important to realise that while all this is occurring in one rotor, in the other rotor the rotor is exactly a hundred and eighty degrees offset from this rotor.
So, the opposite going to be occurring in there.
So, you’re about to start your combustion with the sports firing your ending your exhaust stroke over here, and you’re starting with your intake stroke over here.
Here we have the eccentric shaft and as you can see see these rotors are gonna be placed at a hundred and eighty degrees apart, and that’s done so that it balances on that axis so as this rotates its going to be well-balanced.
It was all said it wouldn’t be balanced. But, now you will still have a moment occurring because you’ve got one rotor going this direction, in other going this direction simultaneously.
But, because all of this is rotational, and because it’s balanced vertically along the axis. it’s gonna be a very smooth.
It’s also a very low vibration running engine.
So, let’s see if we can make sense of how this will work out so.
Here we have a rotor which will be on one end and then are eccentric shaft which will go inside of that and then our other rotors going to go on to the other lobe.
Of course, it’s going to be a set of agreements. It’s gonna look something like that and see you can see that the inside of this rotor has this year and so this year is actually gonna mess up with this stationary year and so as that rotor rotates, it’s going to force the eccentric shaft to rotate.
Because this is stationary, so that year’s gonna mess with this year and then forced that low to turn, as you can see demonstrated.
That’s it! As found on Youtube
