Vehicle Compression Test with WPS500X | #PicoScope #Howto #Mechanic
Compression tells only part. In Pico Automotive Diagnostics' most-watched upload this week, Phil Rutt uses a WPS500X pressure transducer on a 1.6 FSI gasoline engine to examine inlet and exhaust valve events, not just a single pressure reading. “Vehicle Compression Test with WPS500X | #PicoScope #Howto #Mechanic” has reached roughly 350,000 views.
The week's other upload turns from capturing a waveform to sharing one. In “15,000 Waveforms in the PicoScope Waveform Library! 🎉 #PicoScope,” Rutt explains how users can search, download and contribute captures. It drew a much smaller audience, but offers a useful companion to the practical lesson: somewhere to find reference waveforms when a signal needs context.
The earlier cam-and-crank correlation overview remains the channel's busiest video by current daily views, followed by the compression test. Steve Smith's metal-strap resonance demonstration also continues drawing attention.
Pico added about 7,000 subscribers over the week, while daily viewing is running well above its usual pace. Nearby motoring channels Joe Achilles and Tyre Reviews are having slower viewing days than usual; Pico's week centers firmly on the diagnostic bench, with both a new test and a growing reference library.

Which stroke in a four-stroke engine squeezes the cylinder's contents before combustion?
During the compression stroke, the piston moves upward with the valves closed, compressing the cylinder's contents.
