Ignition timing | Digital Degree Wheel 4
The instrument for the 2-stroke and 4-stroke ignition timing engine
It is an essential instrument to know precisely the exhaust port and transfer ports diagram of 2-stroke engines and the degrees of opening and closening of the valves in the 4-stroke engines.
The Digital Degree Wheel 4 reads 100 times per second the absolute position of the crankshaft in order to not miss also a hundredth of a degree of measurement. It is possible thanks to the mechanical and electronic features of the encoder and of the display unit which are completely designed by Prisma Electronics
Example of application on a go-kart engine
The right 2-stroke engines phase diagram design is one of the most relevant and most important aspects when trying to improve performance in terms of power. It is even more important than in 4-stroke engines. Using the Digital Degree wheel 4 it is possible measure the diagram with 0.1° accuracy.
- Tuning up of the camshaft in the 4-stroke engines
