Caterpillar continues to provide engines that meet the regulations of various agencies around the world. Each engine is certified to meet emission regulations by using the proper iron, software (flash files), and fuel settings. Unauthorized changes to any of these components may cause an engine to not be compliant with emission regulations. This is considered as tampering. Tampering with an engine can make the reliability and durability of the engine decrease.
Note: Changes to engine ratings may require decals in order to comply with emission regulations.
The Caterpillar Factory Password System (FPS) was developed in order to facilitate the access of factory passwords with an on-line download. The FPS was recently enhanced in order to ensure that all certified Caterpillar engines meet the original emission certification status after rebuilds and rerates are performed.
Unauthorized changes that are made to the full load setting or full torque setting can be considered as tampering. Each engine's fuel rate (FLS and FTS) is factory set in order to produce the announced nominal horsepower. Certifications allow the manufacturer to change the fuel rates in order to meet emission regulations. Adjustments to fuel ratings can only be made within these certified limits. Any adjustments that are made outside of the ratings are considered to be tampering. The dealer is responsible for complying with emission regulations after a rebuild or repair is completed. The dealer must use the proper iron, software, and fuel settings in order to comply with the emission regulations. Unauthorized settings can damage equipment and components. The Environmental Protection Agency can issue fines to dealers and owners for engines that do not meet emission regulations due to tampering. Similar fines can also be issued by other regulatory agencies worldwide.
