hat is the Old Vehicle Retrofit Program?
A program operated by Neutronics Enterprises, Inc. to upgrade the
emission control systems of certain older vehicles. It is designed to assist
people whose vehicles have failed smog checks and who want to keep their
Who is responsible for the program?
Neutronics Enterprises, Inc., working in conjunction with the Air Pollution Control District of San Diego County.
Why did I fail my smog test?
All car components wear out. Something in your car has worn enough that combustion in the engine is incomplete and emissions are higher. Your car may also be experiencing poor fuel economy as a result.
What does "higher emissions" mean?
Perfect combustion produces harmless carbon dioxide (CO2) and water vapor. When combustion is incomplete or inefficient, harmful smog-forming pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) are also produced. To minimize these pollutants, vehicles are equipped with an emission control system, which included a catalytic converter on most 1975 and later model-year vehicles.
How can I repair my car?
Depending on the specific problem, repair might range from minor adjustments to major engine work. If your vehicle requires more than a tune-up, your catalytic converter and other emission control components might need to be replaced. The cost of these repairs could easily exceed $300.
What else can I do?
Neutronics Enterprises, Inc. markets an emissions upgrade kit especially designed for 1975 and newer vehicles without electronic fuel injection or computer controlled carburetors. The kit adds feedback computer technology and fuel/air mixture of your vehicle and replaces the old catalytic converter with a new-technology three-way catalytic converter. This system significantly reduces the exhaust emissions and may also improve fuel economy.
The Neutronics Enterprises, Inc. kit has been tested to 30,000 miles on a fleet of vehicles and is warranted for two years. It will ensure that you pass the Smog Check inspection and should last many years, providing you continue regular tune-ups. The kit has been approved by the California Air Resources Board and the Bureau of Automotive Repair. Normally,
it would retail for $500. Because of a special program awarded by the San Diego Air Pollution Control Board, qualifying vehicles registered in San Diego County can be upgraded for $150 or less. Details are available from an authorized installer.
