Abstract: An apparatus of controlling an engine includes a controller determining an inflow fuel amount adsorbed on an inner wall of a cylinder, and introduced into an oil pan based on the density of a combustion chamber and a post injection fuel amount, determining a vaporization fuel amount vaporized in the inflow fuel amount based on an operating condition of an engine, determining a consumption fuel amount consumed in the vaporization fuel amount based on the operating condition of the engine, and determining a dilution rate of the engine oil based on the inflow fuel amount, the vaporization fuel amount, and the consumption fuel amount; and a display providing an alarm to a driver when the dilution rate of the engine oil is equal to or more than a reference value.

Abstract: An exhaust gas recirculation (EGR) cooler includes: a housing including a cavity in which a plurality of tubes are received, and including a coolant inlet conduit allowing a coolant to flow into the cavity therethrough and a coolant outlet conduit allowing the coolant to be discharged from the cavity therethrough; a bypass conduit provided in parallel to the housing; an inlet header sealingly mounted on a first end portion of the housing; and an outlet header sealingly mounted on a second end portion of the housing. The inlet header may include an EGR valve housing, a bypass valve housing, and a cooling chamber defined in the EGR valve housing and the bypass valve housing, and the cooling chamber may be fluidly connected to the cavity of the housing through the coolant outlet conduit.

Abstract: Provided is a light emitting diode (LED) lamp assembly having an increased light incidence angle by fixing unit LED lamps fixed on a substrate at various angles. The LED lamp assembly includes a substrate having a socket portion and an LED mounting portion, first unit LED modules installed on both surfaces of the substrate and irradiating light onto the both surfaces of the substrate in a frontward direction, and second unit LED modules irradiating light onto the both surface of the substrate in directions other than the frontward direction. In the LED lamp assembly, since first and second unit LED modules having light irradiation units formed at different positions are installed on both surfaces of a single substrate, light can be irradiated in a radial direction.

Abstract: The object of this invention is to provide a non-calcined clay composite used as building materials capable of promoting humans' health and being desirably used irrespective of location, which is improved in terms of strength without calcining clay. Because the non-calcined clay composite is produced without calcining clay, the process of producing it is simplified and its productivity is improved. The non-calcined clay composite includes 50 to 90 wt % clay, 2 to 30 wt % lime, 4 to 48 wt % blast furnace slag, 0.04 to 0.9 wt % alkaline chemical, and water as a balance, and has high compression strength due to an ionic coagulation reaction, a pozzolan reaction, and a latent hydraulic reaction.
