6.11 IGN ignition angle measurement module
IGN technical specs
imc CANSAS-IGN is a module for determining the ignition angle of gasoline engines. The module has
electrically insulated inputs for connecting the ignition signal, a crankshaft sensor and a reference signal,
as well as any camshaft signal. Based on the ignition time and the crankshaft position, the module
determines the ignition angle and the engine's current rotation speed.
CANSAS-IGN
Ignition signal
The ignition signal is measured to determine the exact moment of ignition. Based on this time and the
crankshaft position, the module determines the ignition angle.
The ignition signal can be captured byinductive
transducers (e.g. clamp ignition sensor).
The resulting signal contains the typical pointed and high
pulses at the moment of ignition. The measurement is
performed at the ignition coil's secondary line. The pulses
can reach up to 100V.
Ignition signal: High level
