In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin (PAO) by volume, and 0.06% red dye by volume. A viscosity of the composition at 100 degrees-C. ranges between substantially 7.2 and 7.6 centistokes (cSTs).

Abstract: An apparatus and a method are provided for a crankcase breather vent assembly to direct blow-by gases out of an engine crankcase. A vent base comprising a generally cylindrical vessel communicates received blow-by gases into an interior cavity of a breather vent that comprises a filter medium. Baffles disposed within an interior cavity of the vent base capture oil carried along with the blow-by gases. The captured oil is directed to an oil sump of the engine by way of a suitable hose. A bonnet fastenably receives the breather vent and is configured to reduce a buildup of oil residue on nearby engine components. An outer profile of the breather vent is tapered along a longitudinal dimension of the filter medium to facilitate unrestricted air flow through the filter medium when the bonnet is installed onto the breather vent.

The method comprises: cutting off fuel to the engine during a deceleration event; open loop operating the engine air/fuel ratio rich of stoichiometry for a predetermined time after the deceleration event; feedback controlling the air/fuel ratio on average near a value rich of stoichiometry for a preselected time after said predetermined time; and feedback controlling the air/fuel ratio returning to stoichiometry after the preselected time.

Abstract: The present invention relates to an apparatus and a system that may be utilized to maximize and utilize greater air flow through an intercooler apparatus. The present invention utilizes unique coil configurations and designs to help promote better air flow through an intercooler apparatus. The present invention utilizes unique profiled passage separators to improve air flow through the passages of the intercooler. Additionally, the present invention utilizes profiled passage separators that improve and significantly cool temperatures of the air flow in much smaller packaging because of the unique passage separators and air flow design of the intercooler.

The common controller includes switches that selectively connect power to a voice coil motor and a spindle motor of the desired storage drive. The common controller further includes a switch that controls the preamp of the desired storage drive and a switch that controls the flow of data to and from the desired storage drive.

Abstract: An apparatus is provided for an intercooler to maximize air flow to a turbocharger. The intercooler comprises an intercooler core comprising an alternating arrangement of air flow passageways and charge flow passageways. The air flow passageways receive an ambient air flow and the charge flow passageways receive a charge flow, such that heat is transferred from the charge flow to the ambient air flow and removed from the intercooler. A first end tank sealed to a hot side of the intercooler core conducts the charge flow received at a hot fluid inlet to the intercooler core. A second end tank sealed to a cool side of the intercooler core conducts the charge flow from the intercooler core to a cool fluid outlet. A multiplicity of partitions disposed on the hot and cool sides of the intercooler core are configured to promote a laminar flow through the charge flow passageways.

Abstract: A combined mass airflow sensor and hydrocarbon trap is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. The combined mass airflow sensor and hydrocarbon trap comprises a duct that supports a hydrocarbon absorbing sheet in an unfolded configuration within a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.

Abstract: An apparatus and a method are provided for a filter airflow demonstrator to provide a visual representation of resistance to air flow through an air filter. The airflow demonstrator comprises a housing that includes an opening configured to receive the air filter. An edge portion of the opening receives a perimeter of the air filter, such that a filter medium of the air filter is disposed over the opening. An electric fan within an interior of the housing draws the air flow through the filter medium into the housing. A transparent stand pipe is disposed atop the housing, such that a lumen of the stand pipe transports the air flow from the interior to an exterior of the housing. A ball within the central lumen travels upwards therein under the action of the air flow to provide an indication of resistance to the air flow through the air filter.
