FirstLook™ Timing Charts
Four Cycle Engines
(in Adobe PDF format. Need the Adobe Reader?)
The following chart displays the cylinder exhaust and intake event timings for a four cycle engine at various engine speeds. This is the key to using the FirstLook™ Engine Diagnostic Pulse Sensor.
Important points to note in the chart for setting up your automotive diagnostic scope are noted on the far right. These points allow for full-scale viewing of one cycle (or two rotations) of a four cycle engine at working RPM ranges.
