||||
| Vehicle Inspection Report (VIR) | show 🗑
|
||||
| show | A failing vehicle is eligible for one free retest at the original station if it returns with 30 days of the initial test.

|
||||
| Tampered Systems | show 🗑
|
||||
| Referee Process | show 🗑
|
||||
| Gasoline | show 🗑
|
||||
| show | Exhaust pollutant that is unburned fuel from incomplete combustion or a misfire.
🗑
|
||||
| show | Toxic exhaust pollutant formed when there isn't enough oxygen to support combustion.
🗑
|
||||
| show | Exhaust pollutant that is highly toxic and increases when combustion chamber temperatures exceed 2,500 deg. F.
🗑
|
||||
| show | Fuel ratio below 14.7:1 that represents an excess of gasoline and not enough oxygen.
🗑
|
||||
| show | Fuel ration above 14.7:1 that represents an excess of oxygen and not enough gasoline.
🗑
|
||||
| show | Ideal fuel mixture of 14.7 parts oxygen to 1 part fuel. (measured by weight)
🗑
|
||||
| show | Exhaust gas that is a good lean indicator.
🗑
|
||||
| Carbon Dioxide (CO2) | show 🗑
|
||||
| show | Precombustion emissions control that allows a small amount of exhaust gas mix with the air/fuel entering the combustion chamber to reduce the volatility of the mixture and reduce NOx production.
🗑
|
||||
| show | Valve location on top of the engine for the purpose of regulating the flow of blow-by gases being removed from the crankcase.
🗑
|
||||
| Evaporative Control System (EVAP) | show 🗑
|
||||
| show | Valve located in the gas cap that is designed to open and fresh air to enter the fuel tank to relieve vacuum that might build up during cooling down periods.
🗑
|
||||
| show | A valve found in the fuel cap that is designed to relieve pressure that may develop in the fuel tank. If pressure gets to be excessive, this valve opens to lower internal tank pressure.
🗑
|
||||
| Air Injection Reaction (AIR) | show 🗑
|
||||
| Non-Pump (Pulse Air) System | show 🗑
|
||||
| show | Valve used to control the flow of exhaust gas back into the intake and can be controlled by either vacuum, pulse-width modulation or other electronic controls.
🗑
|
||||
| show | Located in the exhaust stream, it uses the heat from combustion, unburned fuel, and air in the exhaust stream to convert the pollutants into environmentally acceptable non-pollutants.
🗑
|
||||
| show | Temperature around 500°F when a catalytic convertor begins to work.
🗑
|
||||
| Oxidation Converter | show 🗑
|
||||
| show | Catalytic converter that reduces NOx emissions by reducing them back into their main components of N2 and O2.
🗑
|
||||

||||
| Closed Loop | show 🗑
|
||||

🗑
|
||||
| show | Warning to indicate a sever misfire that can cause Catalytic Converter damage.
🗑
|
||||
| Misfire | show 🗑
|
||||
| show | Onboard diagnostic test that is executed by the PCM.
