An apparatus includes a dosing module structured to suspend dosing in an exhaust aftertreatment system; a selective catalytic reduction (scr) inlet nox module structured to interpret scr inlet nox data and an scr inlet temperature; a scr outlet nox module structured to interpret scr outlet nox data; and a system diagnostic module structured to determine an efficiency of a scr system based on the scr inlet and outlet nox data over a range of scr temperatures, wherein the system diagnostic module is further structured to determine a state of at least one of a diesel oxidation catalyst (doc), a diesel particulate filter (dpf), and the scr system based on the scr efficiency at an elevated scr temperature range and the scr efficiency at a relatively lower scr temperature range relative to a high scr efficiency threshold and a low scr efficiency threshold.. .

Tailored oils produced from recombinant oleaginous microorganisms


Methods and compositions for the production of oil, fuels, oleochemicals, and other compounds in recombinant microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a keto acyl-acp synthase enzyme, a fatty acyl-acp thioesterase, a fatty acyl-coa/aldehyde reductase, a fatty acyl-coa reductase, a fatty aldehyde reductase, a fatty acid hydroxylase, a desaturase enzyme, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel, as well as oleochemicals such as functional fluids, surfactants, soaps and lubricants..

Universal synthetic lubricant, method and product-by-process to replace the lost sulfur lubrication when using low-sulfur diesel fuels


A diesel fuel lubricant as a replacement for sulfur lubrication in ultra-low and low sulfur diesel fuels, the process for producing said lubricant, and the method of using said lubricant. This lubricant comprises alpha-olefins; low odor aromatic solvents; and at least one a base oil selected from the base oil group consisting of hydroisomerized high base oils and ht severe hydro-cracked base oils; as well as other ingredients.
