What Does A Bubble Emission Test Do, And Why Is It Done?

Using technology like bubble emission tests, manufacturers can identify bubbles in a material before it is even made or assembled. Learn about how these tests work and why you should use them for your manufacturing process by browsing to flexpakinc.com/test-methods/bubble-emission-test.

What does a bubble emission test do?

A bubble emission test is done to check the amount of air in an engine. It's typically done by filling an engine with a gas, and then blowing a blast of air at it. The amount of time it takes for the engine to start leaking bubbles into the gas shows how much air is in the engine. If there is more than 50% more air than petrol, then the car will stop running.

How to Perform a Bubble Emission Test?

A bubble emission test is a way to examine the quality of the fuel used in an engine. It works by being able to determine how much fuel is being lost during the combustion process of an engine. The air mixture has bubbles added into it in order for the test to work. 

When ignited, these bubbles allow the testers to examine how well the engine can actually combust properly. This information can then be used by mechanics in order to improve the overall efficiency of an engine.

How is a Bubble Emission Test done in an engine?

Every type of engine uses a fuel in order to create energy, but the molecules in this fuel are not all the same. For example, one type may have more of a heavy element or light element. The mixture needs to be balanced to maintain proper combustion and prevent engine knock which happens when there is an imbalance in the mixture. 

There is also a danger of knocking which can cause expensive damage to your engine. A bubble emission test is done on the air intake where air bubbles are injected into the engine's cylinders during the test and then they are burned off by sparks from electrodes.
