Vacuum Gauge

Vacuum Gauge is a device for measuring pressures below atmospheric pressure.Vacuum gauges are connected to control units via cables; the control units afford power supply, analysis and display of the measured data. These devices usually also have analog voltage outputs.

Vacuum is generated in a car engine by the action of the pistons moving up and down, sucking air in during one cycle of the strokes. To give the ideal air fuel mixture the air feeding the engine is restricted therefore a vacuum forms. The vacuum is often made use of by the braking system which uses it to provide power and assist in actuating the breaks. The vacuum level can be used by a hypermilling driver to improve driving technique. The lowly vacuum gauge is the grand-daddy of fuel economy instrumentation.

Installing and using one remains a cost effective way to help a driver fine tune certain driving tasks for better efficiency, particularly driving with load .As well as aiding efficiency, adding a vacuum gauge is useful as an indicator of the general health of an engine.

The purpose of a vacuum gauge is to measure how much throttle you are giving and how much load is on the engine. How it helps is by giving you feedback as to how hard you are on the throttle and can therefore ease off a little on the uphills and generally drive with as much vacuum as possible.
