Abstract: Disclosed is an exhaust gas purification catalyst with a multilayered structure including an ultra-thin layer with a thickness of 20 micrometers or less and containing Rh, Pd, or both as at least one precious metal component, and to a method of manufacturing the same. The method includes a step of forming an ultra-thin layer having a thickness of 20 micrometers or less as the top layer of the catalyst by applying a polymer coating solution containing a polymer having a functional group capable of chelating with the precious metal component(s) on the surface of the multilayer structure of the catalyst. The disclosed catalyst exhibits improved removal efficiency for THC, CO, and NOx contained compared to an existing thin film-type catalyst. Since the disclosed catalyst is coated with a thin coating layer containing at least a portion of precious metal components, the disclosed catalyst exhibits improved performance while using the same amount of precious metal components as in conventional catalysts.

Abstract: A method for controlling an internal combustion engine including at least one exhaust-gas aftertreatment component having an electric heating element, the electric heating element heating the exhaust-gas aftertreatment component and the exhaust gas flowing through the exhaust-gas aftertreatment component, the electric heating element briefly or permanently being acted upon by a heating current, a gas, in particular fresh air and/or exhaust gas, flowing downstream through the exhaust-gas path. In the method, a first temperature upstream from the at least one exhaust-gas aftertreatment component is ascertained, a second temperature downstream from the exhaust-gas aftertreatment component is ascertained, and the exhaust-gas mass flow of the internal combustion engine is ascertained as a function of a first temperature difference between the first and the second temperature and a heating power of the electric heating element, and the internal combustion engine is controlled as a function of the exhaust-gas mass flow.

Abstract: Modestly modified automotive engine powered generator systems to substantially improve capability for providing renewable electricity powered grid reliability and energy storage are disclosed. The use of these engines to improve capability for non-grid electricity generation, including affordable and clean fast charging of electric vehicles, is also disclosed. In one embodiment, these automotive engines use high RPM and stoichiometric air fuel ratio operation so as to provide the advantages of substantially reduced cost and NOx emissions. These engines also have multifuel capability that provides highly flexible use of low carbon fuels (such as hydrogen, methanol and ammonia) as well as the use of present fuels that are widely available. When these low-carbon fuels are produced with excess electricity from the grid and supplied to the grid when there is an electricity-supply shortfalls, they can serve as a means of energy storage.
