My recall service was done today. The MC cap was fine, but the evap canister had started to melt. The dealer did not have one, so they robbed one from a new Spyder and installed it on mine.
What are the legal ramifications of altering the emissions system? I've always understood that to sell the vehicle, it must meet EPA. (I know that most folks wouldn't think to check before buying, but my question is one of legality, not practicality). Would you have to reinstall the canister before selling it?
It's just me; but I'd sure put it back before selling the bike...
The recall did include wrapping the "charcoal canister". My purge valve had gone bad and the dealer did not replace the canister so it was most likely full of fuel.
i was told besides the stupid heat tape they are going to install the dealer also said they were going to move or replace the canister i am getting old but i know he mentioned it
The EPA emission regulations impact manufacturers, distributors, dealers, OEMs, repair shops, rental centers and, as a result, end users.
All of these requirements are rolled into Title 40 of the U.S. Code of Federal Regulations under Sections 40 CFR 1054 and 40 CFR 1060. But, let’s face it, who has time to weed through and make sense of it all? To really understand what it all means, let’s break that down into something a little easier to digest.
What It’s About
To really understand how this affects consumers, it’s necessary to first take a look at what the regulation impacts: evaporative emissions. When liquid gasoline turns into a vapor, which happens when it’s warmed, evaporative emissions result. Everyone has smelled gas while filling a car’s tank or opening a fuel container on a warm day; that smell is the vapor.
The regulations aim to control running losses and permeation losses from fuel systems. Many people are surprised to learn just how much fuel vapor passes through the walls of untreated plastic fuel containers alone. Permeation is just one way in which fuel vapors are emitted, though. Evaporative emissions occur when an engine is running as well as through diurnal loss, when the engine isn’t running, due to daily temperature changes.
What It Looks Like
Some manufacturers have been ahead of the game in improving products to meet the standards. Those manufacturers employ a number of methods to control evaporative emissions, from special hoses to fuel caps on sealed fuel tanks to carbon canisters and vapor control valves. Here’s a breakdown of what that looks like inside any new equipment a consumer may purchase.
Hoses that come in direct contact with liquid gasoline must now be special low-permeation fuel hoses, which are manufactured specifically to limit the amount of fuel vapors that permeate through the hose wall. The hoses need to be kept free of kinks and obstructions to ensure good working order.
Most fuel systems are now sealed, and vented fuel caps have been primarily replaced with sealed caps to prevent evaporative emissions. When a sealed cap is used, there will be different hose connections. In addition to the normal fuel hose connection at the bottom of the tank, there also will be a connection for the vapor hose at either the top or bottom of the tank.
There’s one exception to the sealed fuel cap on some small engines, though. In those cases, the fuel cap self-vents through a carbon canister. The canisters come in different shapes and sizes and may be anywhere on the equipment, which makes it difficult to identify. The best method for locating a carbon canister is to first look for the spot where the vapor hose connects to the engine intake system, and then work backward toward the fuel tank. If the vapor hose connects directly to the tank, there will be no carbon canister. If the vapor hose appears to first go to a box, that is most likely the canister.
The carbon canister works to absorb diurnal vapors. When the engine runs, an intake vacuum draws any vapor from the tank into the engine, where it is burned. After the engine is shut off, vapors continue to be emitted into the atmosphere due to temperature changes throughout the day. The carbon canister absorbs those vapors, and when the engine is started again, the engine intake vacuum will draw in fresh air through the carbon canister’s vent port and thus purge the stored vapors.
Some engine manufacturers also are incorporating optional vapor control valves in new systems. These devices prevent liquid fuel from getting into the vapor system. Originally developed to prevent fuel leakage during rollover accidents, these also might be referred to as “rollover valves.”
What’s Now Required
Beyond making the adaptations to the new systems to limit evaporative emissions, OEMs must complete several steps to ensure adherence to the EPA’s regulations. This includes registering through the Verify system, labeling engines according to the standards, and providing emissions-related warranties. This all effects the look of new equipment, as well as adding new warranty guidelines of which consumers should be aware.
The EPA’s Verify information system collects data on emissions and fuel economy compliance for all sizes of engines. Each manufacturer must register with the EPA and apply for evaporative certification for its equipment through Verify.
Under the regulations, manufacturers also will need to place an approved evaporative emissions label on the equipment. This label must be permanently affixed or engraved on the engine and will include the heading “EMISSION CONTROL INFORMATION.” It will be followed by the manufacturer’s corporate name and trademark, the EPA’s standardized designation for the emission family and the date of manufacture. The EPA also requires that the label include the emissions compliance period, in hours, over which the engine exhaust emissions system was tested. A statement certifying that the engine meets exhaust emission regulations also must be included. While more information can be added, the above is what’s required on any engine-operated equipment now manufactured and sold in the United States, so expect to see it on any new purchases.
Each piece of new equipment also must come with an approved evaporative emissions warranty statement. Under this requirement, consumers purchasing the equipment, along with each subsequent buyer, will know that the engine, along with all of the parts of its emission control system, meets two conditions. First, at the time of sale the engine is designed, built and equipped to meet EPA regulations and, second, that there are no defects in the workmanship or materials that would keep the engine from meeting emission standards.
The EPA requires a minimum two-year emission-related warranty, although exceptions are made for some engines. The warranty covers any component that, should it fail, would increase the engine’s emissions of a regulated pollutant. Manufacturers will spell out all of the warranty details in the owner’s manual and provide a toll-free phone number and email address so that consumers can quickly file a warranty claim and have authorized repairs made so that they are not without their tools for long.
What Can’t Be Done
With these new standards in place, it’s no surprise that some things now can’t or shouldn’t be done.
First and foremost, don’t tamper or attempt to modify engines designed to meet EPA standards. Not only is it illegal and comes with civil penalties, but it can cause a host of problems. For example, removing an engine’s vapor control valves presents a fire hazard and can cause liquid fuel in the vapor system to severely damage the carbon canister.
Knowingly disabling an emission control system component, from tweaking the fuel or exhaust system to altering the engine’s performance, will violate the EPA regulations. Installing a part that differs from that originally on an engine that meets EPA standards also may bring penalties for tampering.
Even without EPA penalties, it would be foolish to attempt to make changes. This equipment has been manufactured to be the best for not only the environment, but the long haul. With basic maintenance, it’ll run long into the future and provide a great return on investment as the latest technology is powering the generator, pump or other piece of equipment. Normal maintenance (replacing air filters and spark plugs) and routine servicing, adjusting the fuel mixture within the allowable range or replacing jets for high altitude operation are still perfectly acceptable.
Finally, don’t try to replace a carbon canister cap with a standard cap. Equipment that meets the so-called “50 state” product distribution guidelines — meaning it meets CARB standards and can be sold in California — may have a special fuel cap with a self-venting carbon canister built in. Replacing these caps with a standard cap, or replacing a sealed cap with a canister cap, violates EPA regulations.
What Can Be Done
The manufacturer should provide a list of any critical emission-related maintenance. This might include any adjustment, repair, replacement or cleaning of the components used to control emissions. Other recommended maintenance and the corresponding schedules also will come from each manufacturer.
In terms of the warranty, each new engine sold will offer at least two years of warranty coverage on its emission components. The warranty covers the repair of emission-control-related parts that are found to be defective within the first couple of years of service. Each manufacturer will include a phone number and email address in the operator’s manual to ensure quick, easy access to filing a warranty claim. Ensure none of these parts are tampered with since that may void the warranty, but know that things will get repaired quickly when needed.
Follow a manufacturer’s maintenance schedule closely for new equipment, as well. Generators and other small-engine equipment will last even longer than anticipated when routine care and maintenance are performed according to the operator’s manual. Be sure to seek out qualified engine technicians for assistance on more advanced tasks to ensure the engine will continue to meet EPA standards and run smoothly into the future.
This overview of the EPA’s standards still may not make fun fodder. Understanding the component parts involved in reducing emissions will make it easier to perform basic services and preventative maintenance. Knowing the do’s and don’ts under the standards will ensure warranty claims are a breeze and that the equipment runs at peak performance, both of which are sure to maximize the investment.
