Title: R Douglas Hudgens: Innovator in Engine Cooling Solutions
Introduction
R Douglas Hudgens is a notable inventor based in Cookeville, TN (US). He has made significant contributions to the field of engine cooling systems, holding a total of 5 patents. His work primarily focuses on antifreeze compositions and supplemental coolant additives that enhance the performance and longevity of cooling systems in various vehicles.
Latest Patents
One of Hudgens' latest patents is an engine antifreeze composition. This invention relates to an antifreeze composition that can be used in the cooling systems of internal combustion engines, such as heavy-duty diesel engines, light-duty trucks, and cars. The antifreeze composition can be added to water or other suitable liquid coolant in the cooling system to lower the freezing point temperature of the coolant and inhibit corrosion of metallic components associated with the cooling system. This composition is particularly well suited for use with hard water and includes an organic acid component comprising adipic acid and at least one of benzoic acid and one or more C-C dicarboxylic acids or salts of these acids. Additionally, it contains other anti-corrosive additives, such as molybdate, nitrite, nitrate, silicate azoles, and various buffer agents.
Another significant patent is for a hybrid supplemental coolant additive. This invention relates to a supplemental coolant additive for use in cooling systems, particularly in diesel engine cooling systems. The supplemental coolant additive includes a C-C dicarboxylic acid, preferably adipic acid, and optionally a C-C aliphatic dicarboxylic acid, an aromatic monocarboxylic acid, an aromatic dicarboxylic acid, and salts of these acids. This additive can also include a variety of other additives, including molybdate salts, nitrate salts, nitrite salts, silicate salts, and buffering agents. It is preferably provided as a solid additive or a liquid concentrate, which can be added to the liquid coolant over time to enhance coolant life and provide increased anti-corrosion protection in cooling systems that include hard water.
