timing in PD Racing systems (inner rotor) |
|
|
|
The diagram here shows timing of spark in depencence of engine speed in
our sports systems with inner rotor. The line zero respresents the angle you set at point of installation by aligning stator and rotor markings with the piston in the wanted ignition position (say 2 mm before TDC which might be something like 25° or so). At start, something below 3000 revs ignition will happen later, nearer to TDC, here shown in the negative area of the graph. During main driving revs, say between 3000 and 10000 ignition happens in about the set timing (zero line) and in higher revs it again drops back a little towards TDC (the negative area here). This is something inherent in the material, but corresponds very well to what a 2-stroke engine would like. |
