IMC's CANSAS-IGN module has been designed for simple measurement of ignition angles on combustion engines.
This compact, stand-alone module calculates ignition angle and engine speed in real time, per cylinder, for up to 12 cylinders. These calculations are based on the ignition signal, the crankshaft position signal, an absolute angle reference signal and the camshaft position signal. The high-speed, high-resolution sampled signals are stored in the module, and the display angle and speed are digitally displayed and output via CAN bus and 0-10V. In the age of hybrid vehicles, it's particularly important to understand the behavior of internal combustion engines. Until now, ignition angle measurements have required elaborate dedicated analyzers that are difficult to integrate into existing test systems.
IMC's CANSAS-IGN module overcomes these obstacles by measuring a signal crossing threshold with a resolution of a fraction of a second (sampling 3Mech/sec). From this measurement, the ignition angle is calculated, giving a crankshaft position with an accuracy of 0.1° (resolution 0.01°) up to 20,000 rpm. Its configurable CAN bus outputs make it easy to integrate into existing test benches. A built-in snapshot mode lets you "see" input signals to determine the right trigger and signal pre-processing settings.
