Fuel Filter

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a fuel filter, particularly for motor vehicles, that improves the separation of water from fuel using a special coalescer made of fibers aligned primarily parallel to the direction of fuel flow. This unidirectional fiber arrangement increases the contact time between water droplets and the fibers, making it easier for small water droplets to merge and form larger drops, which can then be separated more effectively from the fuel.

Use CasesContent extracted from patent full text and abstract with AI.

• Automotive diesel fuel filters for cars, trucks, and buses
• Fuel filtration systems in industrial engines (e.g., generators)
• Marine engine fuel filtration systems
• Fuel purification units for agricultural machinery
• Upgrading existing fuel filtration solutions to improve water separation efficiency

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced water separation efficiency, leading to better protection of engine components
• Reduced pressure loss across the coalescer, making the filter more energy-efficient
• Potentially longer filter life and reduced maintenance frequency
• Improved combustion reliability by delivering cleaner, drier fuel to the engine
• The technology can be manufactured using widely available fiber and nonwoven technologies, allowing cost-effective production
• Can be integrated as a dual-purpose filter for both particle and water removal

Patent Abstract

The invention relates to a fuel filter (1), in particular of a motor vehicle, having a housing (2), in which there is arranged a coalescer (4) for separating out water (6) contained in the fuel (5), which coalescer comprises a coalescer material (7) that is suitable for coalescing water (6), wherein the coalescer (4) is flowed through in the throughflow direction (8). In that context, what is essential to the invention is the fact that the coalescer material (7) has fibers (9) whose primary orientation is oriented essentially parallel to the throughflow direction (8).
