    tops and bottoms, opps, when the small piston is at it's TDC, it's so confusing late at night.

    Ha Ha well, at least then you could say that I'm predictable, more predictable than a lot of two stroke powered machinery ( perhaps a little slower!).
    I do need a night's sleep for my brain to sift through and take in what's been said! - this morning? I dunno - think I may have accidentally shut down my brain instead of my computer last night!

    ( I also understand of course that the message wasn't actually intended for me!)

    Let me put you out of your misery Neil .

    Will, here is some basic explanation, leaving the phase difference between the main crank at TDC and the small crank at TDC aside for now.

    When the main piston is at its BDC, the small piston is at its TDC.

    When the main crank turns 90°, the main piston is about half-way up, about to close the exhaust, and the small crank has turned 180°, so the small piston is at BDC.

    Another 90°-turn for the main crank and another 180°-turn for the small crank, and the main piston is at its TDC, and the small piston is also at its TDC.

    Below is a little program you can play with, provided you use Win98 (on some computers it will also run under Win XP) or a Win98-emulator.

    HCCI.ZIP

    Frits,
    I haven't got WIN 98 computer running at the moment, but last night I had drawn a few basic sketches (which I should have done in the first place!) and so had it already 99% sussed.

    Neil,
    Sorry to put you through having to answer all those basic crappy questions - it's pretty easy demonstrating things to people when they are present but on a forum and when you're about to shut down...... maybe not so easy!

    I still expect you guys to make some allowances for me though! - At least I'm interested!

    I haven't been here much lately - how is the progress with the experimental engine project? I am assuming that this one is straight line piston assembly, FOS? or HCCI (with the little piston that I couldn't get my head around?) or just conventional up top? my guess it's completely new from the bottom of the crankcase up!
    Have you got the Gyro engine sussed out and flying?

    Will, this is a relatively standard engine, I just want something to ride other than the F9.
    this is a rotary valve engine, with the sliding throttle Gibs.
    also using the mark two TPI, all technology with no risk. All ready run these systems, but separately.
    360cc, I just want lots of power with a wide usable torque curve and burn fuck all fuel, simple really.

    a double sided tooth belt (5mm pitch) and 10 tooth pulleys, throttle linkage, one shaft has to turn backwards.
    gyro is sorted, it needs a new Ignitech.

    If this 360 works well with all the new gear, is there the possibility that it could eventually become a single cylinder test bed for a revised (Mk 2) gyro engine? - sounds to me that it might be a good candidate for that role - especially if it has a good torque spread and fuel economy - enjoyable way of testing too! ..........(bigger and more efficient prop maybe ?).

    another step, rear pipe fitted, end will be plugged with exhaust gas being drawn off the center section. I have run the swing arm, with wheel, full travel to be sure nothing collides.

    Looks like you have found a satisfactory way of routing the rear exhaust considering that it will be longer than say a road racing machine!
    ( my life's ambition is to save the two stroke by getting rid of the bulky chambers and smokey exhaust - is that possible?)

    As usual, I haven't really got what you mean about the end being plugged with exhaust gas etc! but.... having looked in ESE, could it be this new fangled and mysterious W.T.F. "I.P." thing they are discussing?? ..... Injection Pulse ?? or could "IP" stand for inverted pipe/stinger as proposed by Gordon Jennings, who wrote the famous two stroke tuning book? (it'll come to me ..... eventually!)

    Guess you used the flat surface of that "hefty" nameplate and the bearing boss (same level?) as a hold down surface/datum on the mill table?

    Hes putting the stinger outlet in the pipe mid section. rather than the end of the baffle cone.

    He needs to do something like ths as he has a lowish reving two stroke with a reverse cylinder so hes runing out of room.
    Remember where and how a normal front exhaust MX bike curls arround Will.
