What is a Portable Engine? An engine designed and capable of being carried or moved from one location to another. Indicia of portability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform. For the purposes of this regulation, dredge engines on a boat or barge are considered portable The engine is not portable if: 1. • • The engine or its replacement is attached to a foundation, or if not so attached, will reside at the same location for more than 12 consecutive months. The period during which the engine is maintained at a storage facility shall be excluded from the residency time determination. Any engine, such as a back-up or stand-by engine, that replace ngine(s) at a e location, and is intended to perform the same or similar function as the engine(s) being replaced, will be included in calculating the consecutive time period. In that case, the cumulative time of all engine(s), including the time between the removal of the original engine(s) and installation of the replacement engine(s), will be counted toward the consecutive time period; or the engine remains or will reside at a location for less than 12 consecutive months if the engine is located at a seasonal source and operates during the full annual operating period of the seasonal source, where a seasonal source is a stationary source that remains in a single location on a permanent basis (at least two years) and that operates at that single location at least three months each year; or the engine is moved from one location to another in an attempt to circumvent the portable residence time requirements. What is a Dual-fuel Diesel Pilot Engine? An engine that uses diesel fuel as a pilot ignition source at an annual average ratio of less than 5 parts diesel fuel to 100 parts total fuel on an energy equivalent basis. What is Tactical Support Equipment? Equipment using a portable engine, including turbines, that meets military specifications, owned by the U. S. Department of Defense and/or the U. S. military services or its allies, and used in combat, combat support, combat service support, tactical or relief operations, or training for such operations. Examples include, but are not limited to, engines associated with portable generators, aircraft start carts, heaters and lighting carts. Return to Previous Page

What is an Alternative Diesel Fuel? Any fuel used in a compression ignition (CI) engine that is not, commonly or commercially known, sold or represented by the supplier as diesel fuel No. 1 -D or No. 2 -D, pursuant to the specifications in ASTM Standard Specification for Diesel Fuel Oils D 975 -81, or an alternative fuel, and does not require engine or fuel system modifications for the engine to operate, although minor modifications (e. g. , recalibration of the engine fuel control) may enhance performance. An emission control strategy using a fuel additive will be treated as an alternative diesel fuel based strategy unless: (1) the additive is supplied to the engine fuel by an on-board dosing mechanism, or (2) the additive is directly mixed into the base fuel inside the fuel tank of the engine, or (3) the additive and base fuel are not mixed until engine fueling commences, and no more additive plus base fuel combination is mixed than required for a single fueling of a single engine. What is a Fuel Additive? Any substance designed to be added to fuel or fuel systems or other engine-related systems such that it is present in-cylinder during combustion and has any of the following effects: decreased emissions, improved fuel economy, increased performance of the engine; or assists diesel emission control strategies in decreasing emissions, or improving fuel economy or increasing performance of the engine. Fuel additives used in conjunction with diesel fuel may be treated as an alternative diesel fuel . What is a Low-Use Engine?
