Vehicle Inspection Reports: VIRs (Day 2)
Part of Lesson Plan: **5 Gases (updated) by Michael Fleming
Activity Overview / Details
Start the second day with the PowerPoint again to briefly go over the 5 gases. The last two slides will be the ones to focus on. Talk about why the vehicle failed smog (what gas?). Since it is Day 2, you can discuss an ASM (Acceleration Simulation Mode) test verse TSI (Two Speed Idle) tests.
After discussing the VIR, go to the next slide and ask students to recognize the pattern of individual gases as the fuel ratio changes. You can also ask what systems and factors contribute to fuel ratio changes.
