Diesel Injector Clean + Cold Flow Additive (cleaner + antigel) to the AMSOIL diesel fuel system Diesel Injector Clean + Cold Flow (DFC) combines the superior properties of an AMSOIL Diesel Injector Clean diesel engine cleaner and AMSOILDiesel Cold Flow anti-caking agent in one bottle. The product is designed for all types of diesel engines, including common-rail high-pressure engines. Unlike all-in-one fuel additives, which can sacrifice performance in certain areas of radio comfort, AMSOIL Diesel Injector Clean + Cold Flow is not a sacrifice; It is designed for all diesel engines that require maximum results. It restores engine throttle response and improves fuel economy. Deposits on fuel injectors impair fuel atomization, its complete combustion, and excessive emissions and smoke are generated. Common-rail high-pressure fuel systems are becoming commonplace as car manufacturers are trying to increase engine power while respecting exhaust emission standards. In high-pressure systems, common-rail pressure, an injection pressure of about 30,000 psi atomizes the fuel into fine mist for more efficient combustion, which leads to increased power and fuel economy while reducing emissions. To maintain these high pressures, the injector assemblies are well designed with gaps up to 1-3 microns thick (human hair is usually about 70-100 microns). Even minimal internal deposits on diesel injectors or other components can lead to sticking and even jamming, lower power, lower fuel economy and lower efficiency. The traditional composition of additives is not intended to eliminate these hard-to-remove deposits. The AMSOIL Diesel Injector Clean + Cold Flow is distinguished by a modern formulation, which ensures stable cleaning of the internal deposits of diesel injectors, carbon deposits, restoration of engine throttle response and operability, as well as improving fuel economy up to 4.5 percent . Regular use of the AMSOIL Diesel Injector Clean + Cold Flow improves performance and maintains clean nozzles. Lubricates the fuel pump and injectors Ultra-low sulfur diesel (ULSD) diesel fuel significantly reduces lubricity, which is critical for controlling wear on fuel pumps and injectors. AMSOIL Diesel Injector Clean + Cold Flow preserves the lubricity of the fuel pump and injectors, increasing service life, saving time and money on operating costs. Helps prevent gelation. As temperature drops, naturally occurring paraffins in diesel fuel begin to crystallize. The temperature at which the fuel is cloudier and loses its transparency due to the release of water droplets and paraffin crystals is called the cloud point. There is a danger of clogging of fuel filters with paraffin hydrocarbon crystals, there is a fuel starvation of the engine, which prevents it from starting. Low-quality fuel thickens already at a temperature of 40ºF (4ºC), the cloud point of most fuels is 32ºF (0ºC). The highest temperature at which the fuel does not flow through the filter unit for a certain time is called the maximum filterability temperature (on a cold filter) (CFPP). AMSOIL Diesel Injector Clean + Cold Flow lowers CFPP to 20ºF (15ºC) in ULSD.
