Technical - Compound gauge -20s what was its purpose?

Aug 02, 2021 Boneyard51Memberfrom Muskogee, Oklahoma. Compound gauges are found all over fire trucks, but I cannot see a reason on a car for one other than an engine that has a charged intake. The pressure is in PSIG and the vacuum side is in inches of Mercury, which translates to about 1/2 of the psi. This gauge has an odd scale, 1to 5 inches of Mercury is ...

Understanding Vacuum and Vacuum Measurement

Understanding Vacuum and Vacuum Measurement

Low Vacuum – also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum – is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance ...

May 08, 2015 The gauge at left shows an extremely low reading, which holds fairly steady. This means the engine is producing less power and, therefore, less vacuum. Common causes of steady low reading are blowby due to worn piston rings or possibly late ignition or valve timing. An extremely low reading could also indicate an air leak at the intake manifold ...

May 19, 2012 This 1989 Dodge B250 camper van with a 318 V8 has a vacuum gauge on the dash. I know vacuum leaks can cause problems like engine running rough, etc, and that’s when the real mechanics pull out the old vacuum gauge…but if the vehicle is running well, can the driver tell anything useful from the vacuum readings? I noticed on my highway drive today that …

Run the engine at idle, low cruise (1800 to 2200 rpm) and high cruise (2500 to 3000 rpm). Note the vacuum readings, and any fluctuations, at each speed. Next, hold engine speed steady at about 2500 rpm for 15 seconds and read the gauge. Now release the throttle and watch the gauge as the speed drops.
