To meet the EPA's emissions reduction requirements, many states are implementing more stringent emission inspection and maintenance (I/M) programs. An I/M program may be currently operating in your state, or could be soon.
Many states have incorporated the OBD testing method as part of the vehicle emissions inspection for 1996 and newer vehicles. These OBD tests replace tailpipe tests by identifying emissions problems through information stored in the vehicle's on-board computer system. Some states have even proposed only testing vehicles with the OBD test, limiting the vehicles that need to be tested to those manufactured in 1996 and later. The I/M 240 is an enhanced emissions testing program, with "240" representing the number of seconds that the tailpipe portion of the test lasts. I/M 240 tests require visual inspection of emissions control devices, an evaporative emissions test, and a transient drive-cycle exhaust emissions test, performed while the vehicle is running on rollers. Many state programs mistakenly fail vehicles in the visual test based on the presence of aftermarket engine products or force older collector vehicles to undergo some type of testing.
Policy makers must properly focus inspection procedures and not confuse legitimate aftermarket parts with emission-defeat devices and tampering violations. The hobby must also pursue proactive legislative initiatives to establish exemptions from inspections for low-mileage vehicles, classic vehicles (defined as 25 years old and older), and newer vehicles. It is useful to remind legislators that the emissions from this small portion of the vehicle fleet are negligible. This is especially true when you consider the low miles typically driven by hobby vehicles and the excellent condition in which these vehicles are maintained.
My engine is not vegetarian-it wants gas.
There is a battle raging in Washington that may force you to put ethanol in your car, whether you want to or not. The U.S. EPA currently allows gasoline to include up to 10 percent ethanol (E-10), a fuel additive made from corn or other biomass sources. The ethanol industry wants the EPA to increase the amount to 15 percent.
Who would object? Millions of owners of high-performance engines and older cars who fear corrosion and other nasty side effects. Ethanol attracts water. In turn, the resulting condensation can corrode the fuel lines, fixtures and tank components (steel, rubber, aluminum, etc). We're talking rust, clogging, and deterioration. For modern cars, the oxygen atom in the ethanol molecule may confuse the exhaust sensor when measuring the fuel/air mixture going into the cylinders. The mixture may be too lean, producing a hot exhaust capable of damaging the catalytic converter. The end result may also be more nitrogen oxides, a building block for smog.
Many newer engines and parts have been designed to be more compatible with alcohol fuels, and E-15 will not be an issue. But E-10 has been a problem for some current and older models, and E-15 may be worse. Many in the auto industry have cautioned the EPA to do more science before it rules on the request.
Why does it matter? The fact is gasoline without ethanol may eventually become scarce or non-existent when you pull up to the pump. We also face an education curve. For many people who already ignore the "contains 10 percent ethanol" sign will not understand that 15 percent may cost them a pretty penny in repair bills.
