To be certified as Top Tier, a gasoline must pass a series of performance tests that demonstrate specified levels of: 1) deposit control on intake valves; 2) deposit control on fuel injectors; 3) deposit control on combustion chambers; 4) prevention of intake-valve sticking. [4] Gasoline marketers agree when they sign on to Top Tier program ...
Techron. Techron is a patented fuel additive developed by Chevron Corporation and sold in its fuel operations (including Texaco and Caltex). It contains a polyether amine-based detergent, which is purported to dissolve deposits in automotive engines and prevent them from building up. Chevron released Techron as an additive in 1981, and began ...
N-Methylaniline as is (neat) does not appear on the U.S. Environmental Protection Agency’s (EPA) List of Registered Gasoline Additives. However, registration can be obtained at higher concentration which maximum authorized dosage depends on a suitable detergent and an effective fuel combustion modifier added to this component.
Polyethylene oxide, or high-molecular-weight polyethylene glycol, is synthesized by suspension polymerization. It is necessary to hold the growing polymer chain in solution in the course of the polycondensation process. The reaction is catalyzed by magnesium-, aluminium-, or calcium-organoelement compounds.
Gasoline can be released into the Earth's environment as an uncombusted liquid fuel, as a flammable liquid, or as a vapor by way of leakages occurring during its production, handling, transport and delivery. [4] Gasoline contains known carcinogens, [5] [6] [7] and gasoline exhaust is a health risk. [8]
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to ...
Tetrachloroethylene is a derivative of ethylene with all hydrogens replaced by chlorine. 14.49% of the molecular weight of tetrachloroethylene consists of carbon and the remaining 85.5% is chlorine. It is the most stable compound among all chlorinated derivatives of ethane and ethylene.
Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of chemicals with more complex structures, such as ethylbenzene and cumene, of which billions of kilograms are produced annually.
