Low temperatures can negatively impact diesel fuel performance. Additives designed to counteract these effects improve fuel flow and combustion in cold climates by preventing the formation of wax crystals and ice, which can clog fuel filters and fuel lines. These products typically contain components that lower the cloud point and cold filter plugging point (CFPP) of the fuel, enabling reliable engine starts and smooth operation even in sub-zero conditions.
Maintaining operability in cold weather is crucial for industries relying on diesel-powered equipment, such as transportation, construction, and agriculture. Such additives prevent costly downtime and repairs caused by fuel-related issues during winter months. Historically, cold weather operation posed significant challenges to diesel engines. The development and refinement of these additives have greatly enhanced the reliability and efficiency of diesel engines in various climates, expanding their operational range and reducing the economic impact of cold weather.
