Diameters for belly and stinger on 2 stroke expansion chambers, tapered header pipes E10 - Duration: 7:08.

greetings two stroke fans, this is a series for those that don't know, About the

secrets of two-stroke expansion chambers. Have a look in the links at the top for

the playlist in previous videos, ok we'll get right into it,

previous video I broached on the subject of pipe diameters and how the pipe

diameters are mostly related to the gas pressures and calculating the gas

the actual gas pressures is extremely complex and there are models used and

one of the most well known by Blair and I've read through all the lines of code

and I can tell you the the pathway to actually achieving all of these

diameters but he also tested all his models against many engines and came up

with some basic empirical rule of thumb values that can be reliably used for the

different types of engines and what to expect, starting with the header pipe the

header pipe dimensions, the belly section neutral chamber diameter in relationship

to the rest and the actual diameter of the outlet in relation to the rest, now

I'll just cover briefly the header pipe and and tapered types of header pipes is

in relationship to not just the port but also the angle of angles of the diffuser

because it's not included in the diffuser timing calculations but what it

does is it aids gas expansion and the movement of the compression wave and if

we've got a lack of angle in our port or a long port we can get more expansion in

the header and likewise if we've got a steep angle here on the diffuser we can

have a higher angle here to actually smooth the effect of the way of going

over there because it can actually break down due to shock waves at the wave

front from a steep change so that aids that and the empirical value is given or

anything between one and three degrees of taper, the neutral

chamber is also in a relationship to the to the gas values again complex and I

can go through that if you like but I think for basic purposes we'll stick to

the empirical values that Blair also gave because they do come from those

models don't forget, the neutral chamber again with gas if we're working for peak

power we want a larger neutral chamber, if we're working for more broader

power we want a more narrow neutral chamber likewise with the tapers the

shallower taper gives us broader power a steeper taper gives us a higher peak so

for working for peak power or working for broad power we have a difference in

not just the tapers but also the diameters okay.

That's fairly intuitive but the one that is not as intuitive is the outlet pipe

size and the outlet pipe size, the reason I got this picture again is comes

back to the port plugging effect aside from the baffle cone reflecting the port

plugging as the exhaust port closes that also after a number of cycles the gas

builds up that pressure also has a has a port plugging effect off the power and

off the peak and outside of the timing of the of the baffle cone so we have to

be aware of that now if we've got an engine we were going for broad power and

we haven't got a high gas peak pressure then we need to back off the port

plugging a bit because if we have a strong port plugging effect and we don't

have much gas and we're trying to use shallow tapers and what not to exploit

more low end power and a broader power range our port plugin could ruin that so

in the case of the outlet pipe if we've got lower gas pressures for broader

power we have a slightly larger outlet pipe and a slightly smaller outlet pipe

to give us a stronger port plugging effect if we've got high peak gas

pressures and numbers for those given by Blair.

Header pipe that's the diameter factor so that's between the exhaust port

diameter which is exhaust port area converted into a round diameter figure,

neutral chamber ratio between the diameter, that's the multiplication

factor, broad power 0.6 times outlet 0.7 times for broader power, there are values

given for the header pipe angles by Graham Bell these are in the 90s, I was

into karting then a bit and tinkered with expansion chambers a bit then but

my biggest time the expansion chambers was in the 80s so I was working from the

Jennings formulas back then and these empirical values that Jennings gave

because he got all those from measuring pipes a lot worked so these were for road

racing bikes however because in the 80s I was road racing two stroke 350 twins,

wasn't everybody, the good ol days. So I think that will do it for today and

what I will get on to yeah so that'll do for the day I can get more

into these complex modeling but for now we'll just stick with the empirical

values so you've got those basic values and as in the previous videos if you

measure up your expansion chamber you can measure the diameters of the pipe

and you can measure the exhaust port area and then there's a conversion

factor to turn that into a diameter to work with the pipe ratio and you can

measure up the angles measure up the lengths for the timing and then you can

measure up the diameters according to these figures and you know if your pipe

diameters are within the ballpark here that's good but perhaps you know the

outlet pipe might be a little bit too small or towards large size and you want

to go the other way you know you don't want peak power you want broader power

and the outlet pipe is a little bit narrow okay if you have a narrow outlet

pipe you're gonna have too much port plugging affect down low you're gonna

knock off your knock off your your low end power

and because you've got not much gas pressure anyway for peak you know you

know the baffle effect isn't as isn't gonna work as well so yeah just a rough

guide there so you can measure your pipe and actually see how close they are and

that might point you to somewhere to being able to make modifications to it

to pep things up a little bit, okay well that will do it for today and

hopefully we'll catch you in the next video and if you have any questions by

all means hit the comment section and ask don't mind answering anything, bye

for now

5 Swim Toys To Help Improve Your Technique | Swimming Tips For Beginners - Duration: 3:39.

- We all know swimming can get a bit tedious

from time to time.

Trawling up and down that black line.

- Yeah, as triathletes, we are often quite guilty

of just sticking to front crawl

and not really changing it up much,

but there's still other ways in which

you can spice up your training

and using toys is one of them.

(bright music)

You're probably wondering what on earth we're talking about,

but I'm afraid we don't actually mean

jumping in the pool with a large inflatable

and messing about.

These are actually toys and tools

that can help you improve your swimming technique.

- Now there's a wide selection of different toys

that you can get,

so we've just picked a selection

that you can add into your training

to make it a bit more interesting.

(upbeat music)

So this is quite a common pull toy

and it's called a pull buoy

and basically, you put this between your legs

and it raises your hips slightly out of the water.

- Yeah, it's great if you are a swimmer

who struggles with sinking hips.

It basically does a similar action

to what a wetsuit would do in open water,

but it also helps to single out your arms,

so you're really working just on your upper body.

You can't really use your legs when you've got that.

If you're just stuck and you can't find a pull buoy

in your local pool, then a kick-board

can work as an improvisation,

it's just a little bit less comfortable.

- So you might have heard people refer

to the pull paddle combo.

And so using a pull buoy and a set of paddles,

you're basically gonna isolate the front end of your stroke.

- Yeah, if you're using large paddles like Mark and I,

then it's very much about power, working on your strength

and if you wanna feel fast,

you can just take the pull buoy out,

keep the paddles on, and use your legs

and it'll give you a great feel of the water.

But if you wanna work more on technique,

there are actually other paddles available on the market.

Slightly smaller ones that'll just really

reiterate getting that perfect stroke.

Now I know we've already mentioned the kick-board,

but as its name says, it's specifically designed for kick.

If you're got a board like this,

you can just place your fingers through the holes

and the whole idea is to be comfortable and relaxed,

resting your forearms on top

so you can concentrate purely on your kick.

- And you don't have to bury

your face into the water either.

Keep your head up so that you can breaths,

most importantly, and then it's social as well,

you can chat to the person next to ya.

But really you're doing it

so you can isolate your leg kick.

- Now another toy, slightly less usual is the snorkel

and if you look closely, you'll notice

that it's different to the snorkel you'd use on holiday.

This one goes down the centre of your face.

So you can concentrate on keeping your head

completely still when you're swimming.

Now a lot of swimmers struggle with the breathing.

It's the movement of the head that upsets the stroke.

But if you've got this, you can breathe

as much as you want and consistently

and then you're purely focusing

on what your arm and legs are doing.

- As you can see, I've got a set of fins on.

And what fins do is basically gonna propel

you out of the water slightly

and make you travel a lot quicker.

And it also improves your ankle flexibility

and I guess it's similar, it's a bit like

an outboard motor does on a boat.

And it's the closest you're gonna come

to feeling like Michael Phelps.

(upbeat music)

- Now we covered five toys in this video

and it might be a little bit daunting.

So if you wanna try before you buy,

quite a few pools will have a pull buoy

or a kick-board at least that you can borrow first.

- Yeah, so you don't have to get all those,

maybe just select a couple that are gonna help you

on some of the areas of the swim stroke

that you're focusing on.
