Engine Diagnostic Sensor
The FirstLook Engine Diagnostic Sensor offers a fast and accurate
method to diagnose automotive engine problems such as burnt valves, bad
injectors and other performance problems without major disassembly of the
engine.
When connected to the exhaust or vacuum side of the engine to be tested the
FirstLook engine diagnostic sensors enables a mechanic to quickly display a
complete picture of core engine performance on a suitable digital storage lab
scope.
The FirstLook sensor requires no external power source and is particularly
suitable for use with a PicoScope automotive
oscilloscope but can also be used with most other modern lab scopes.
“I really liked this unit,
especially the sensitivity it offers in capturing information on each
cylinder” —Professional Tool & Equipment News
How Does it Work?
The FirstLook sensor looks at the pulse waves generated by the normal
operation of an internal combustion engine. All engines produce a predictable
pattern of these pulses and so any change or irregularity in the pulse wave can
be traced back to problems in the engine. The pulse wave can also be affected by
unburned fuel in the exhaust and this abnormality is also detected and
displayed.
In typical use the FirstLook sensor is either placed in the exhaust pipe or
attached to a vacuum port where it detects the air stream pulse waves. When
connected to a suitable dual trace oscilloscope the display shows in real time
the valve, cylinder and injector activity in any two or four stroke, gasoline or
diesel internal combustion engine. By displaying timing triggers on the scope,
observed malfunctions may be pinpointed to specific cylinders. The ability to
identify the specific cylinders where valve or injector problems are occurring
greatly reduces the time and expense required to diagnose engine problems.
Examples of waveforms captured using the sensor are available at the Pico Library of Automotive
Waveforms.
