Embodiment Construction

[0021] figure 1 A schematic diagram is depicted to illustrate an exemplary embodiment of the heating system 100 of the present disclosure. The heating system 100 is part of a fluid distribution system 102 (also referred to as “system 102 ”) that includes an oil storage tank 104 and a dispenser unit 106 . The dispensing system 102 also includes a hose 108 that positions the dispenser unit 106 in flow connection with the oil storage tank 104 . An example of the dispensing system 102 may dispense fuel additives such as diesel exhaust fluid (DEF), urea resin, and types of fuel additives that reduce NOx emissions in diesel powered vehicles.

[0022] As explained in more detail below, the heating system 100 manages the temperature of the fuel additive to avoid crystallization and / or solidification. This feature allows the dispensing system 102 to operate in cold environments with temperatures that drop below the freezing point of the fuel additive. For example, embodiments of the...

Abstract

A heating system (200) for maintaining a temperature of a fuel additive at and / or above a freezing temperature to avoid crystallization. The heating system (200) may be formed with one or more axially configured casings (238, 240, 242) arranged around a hose for transporting the additive. The fluid circuit may also include a central compartment (236) enclosing the flow meter (216). A fluid heater (244) is coupled to the fluid circuit to provide heated fluid, eg, to the central compartment (236). The heating fluid is dispersed throughout the heating compartment (236) and into the sleeves (238, 240, 242), whereby the heating fluid is directed in hot proximity to the hoses and other components handling the fuel additive.

Description

technical field [0001] The subject matter disclosed herein relates to fuel distribution systems, and more particularly to heating systems for use in fuel distribution systems to prevent crystallization of fuel additives at low temperatures. Background technique [0002] Vehicles using diesel emit large amounts of nitrogen oxides or more specifically NO x . These emissions are harmful to the environment. Therefore, technology is in place to reduce these emissions. Selective catalytic reduction (SCR) is the conversion of NOx into diatomic nitrogen (N 2 ) and water (H 2 O) a technique. SCR utilizes a reducing agent and a catalyst. Examples of reducing agents include anhydrous ammonia, ammonia water, and urea. Various standards and / or government regulations establish appropriate solutions for reducing agents, including in one form aqueous urea, commonly referred to as AUS32, and identified as Diesel Exhaust Fluid in North America and abroad Recognized as AdBlue®.
