Air Filtration Test - Bob is the Oil Guy

The filters in this test were tested for both flow and filtration. The pressure drop across a filter is a good indication of its ability to rob the engine of needed airflow and hence power. Obviously the air filter with the least pressure drop is the highest performing. For the filtration test, I used a secondary filter after the filter being tested to catch any particles that passed through ...

Porosity - Wikipedia

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and . Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are many ways to test porosity in a ...

K&N Air Filter Efficiency Testing

K&N Air Filter Efficiency Testing. The air filter industry uses the ISO 5011 testing protocol when testing filtration efficiency and dust capacity. The test protocol calls for the introduction of a measured amount of "test dust" into the air filter at a selected airflow rate. The test is then terminated after the filter reaches a selected level ...

Bad Mass Air Flow Sensor? (7 Symptoms with …

A bad mass air flow sensor won't reliably measure the amount of air coming in through the air filter, resulting in a delay in the fuel delivery during sudden acceleration and a temporary lack of power. In such a scenario, the ECU will sense the drop in engine vacuum first and then using other sensors, will decide if more fuel is required.

Fundamentals of Soil Compaction

• Compaction increases the shear strength of the soil. • Compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dam. • Compaction can prevent the build up of large water pressures that cause soil to liquefy during earthquakes. 3.2 Factors affecting ...
