The Yamaha TZ-head right picture uses both these ideas. Log in or Sign up. That approach is a completely waist since port area don't give any information about port shape. The mechanism of a squish band is to push the gas as close to the spark as possible at the ignition phase. Kurlon , Jun 26,

Tom retired in after a long and successful career. An area change far up on the port will give a completely different change than bimotiln the bottom of the port.

Two Stroke Engine Porting Head Mods Pipe

I ride on high altitude with my KTM Enduro and sometimes the jetting wasn't fine. The different heat release properties will suite different engine characteristics and should be orchestred with the actual exhaust port height, which decides the opening pressure, i.

Finally, the stinger need to be large enough to let the engine breathe. The length becomes critical to pulse resonance over about rpm.

MOTA 2-stroke engine simulation software

The blue line shows the mathematical correct squish band shape. The same port but without auxiliary ports. Time area is still the standard unit for 2-stroke ports since at least At that point the plunging effect at the stinger end will interact with the pipes internal pressure and help to lower the evacuating pressure at piston BDC. The red length is shorter than the blue length in the picture and the gas must pass these gates.

You can compare 2-Stroke and 4-Stroke bikes. This module allows the study of gearboxes and know how a gear ratio change can affect the bike performance.

Expansion Chamber When the exhaust port shape is decided from time area targets etc. Already made pipes for my RD and they're loud and crisp, good biimotion

The same principal can be used to minimize heat transfer at the squish band. In the upper picture there is no barrier to the head surface, more heat transfer to expect due to 2-strooke gas velocity next to the head surface.

Exhaust port opening Many people talk about a port area 2-sroke a target value and indirect refers to a header area with an area factor for the port. We believe that using this software will help your 2-Stroke development or racing results on different 2-etroke of competition. I have some questions about certain modules of RacingSM Software, can you help me?

This version is limited to 1 License per Windows computer without Time Limit and can be used Offline. Overall had helped me a lot on my 2-Stroke hobby as an enthusiast.

Yes, my password is: Developed by Pedro, with more than 20 lines of code, all the know-how applied to software comes from us and also a lot from the legendary Portuguese 2-Stroke tuner LUFO Racing, this software is directed for all 2-Stroke: Many people talk about a port area as a target value and indirect refers to a header area with an area factor for the port.

Calculate 2 or 3-Stage exhausts. This Article Courtesy Of. First check our Minimal Requirements, if your computer has all the requirements: The internal length between the diffusors will also decide the power production characteristics, so if the first diffusor is relative long then it will gain 2-strokf in the lower rpm range etc.

I was searching for a software that allowed me to calculate racing 2-stroke exhausts. To optimize the squish behavior we need to have a constant squish velocity over the squish band. We should then be more careful with the machining precision as the curve height bimotiob since that part of the port is open for a longer time. This version is the most complete.

A bad designed squish band will cause such detonations which will destroy the surrounding metal and sometimes hammer the piston, making it plastic deformed over a big area and size due to the expansion. If the pressure on the piston varies as in the picture at a certain rpm, the area below the curve could represent the work. Bimmotion section describes the basic function and the most important processes in the 2-stroke cycle a tuner need to consider in general and with the Bimotion tuning software in particular.
