Diagnosing Mass Air Flow / Volumetric Efficiency Issues

Saturday, November 11, 2023: 1:15pm - 5:15pm

The Internal Combustion Engine (ICE) is basically no more than a gloried air pump that generates kinetic energy to propel a vehicle. The more ICE design/developments have changed- the air pump analogy remains somewhat of a constant. The ICE has to be able inhale/exhale properly and make accurate measurements of the air coming in and exhaust gases going out are still a crucial part of it. This class will examine different types of air measure systems for fuel calculations, their failures and how to go about accurately diagnosing them. Vacuum leaks, “pirate air” leaks, as well as, intake and exhaust restrictions issues will be discussed. Moreover, a common sense/logical approach to diagnosing them backed up by real world case studies will be presented. Learn how to leverage technology that will aid techs in diagnosing VE issues.
