Abstract: Data collection and analysis processes include collecting energy consumption data from an in-vehicle energy source sensor, collecting emissions data from an in-vehicle emissions sensor, the emissions data reflecting emissions produced by a vehicle, and collecting mileage data from a mileage sensor in the vehicle. The data collection and analysis processes also include processing the energy consumption data and the emissions data as a function of the mileage data, calculating an efficiency rating from the processing, and transmitting results of the processing to a data collection system.

Abstract: An engine includes a cylinder head at least partially defining a valve seat pocket. A valve seat is located proximate to the cylinder head to at least partially define the valve seat pocket. A pocket filler is located between the valve seat and the pocket insert such that the pocket filler occupies a substantial portion of the valve seat pocket. A pocket insert is attached to the cylinder head proximate to the valve seat pocket, such that the pocket insert lines at least a portion of the valve seat pocket.

Abstract: In one exemplary embodiment of the present invention, a fuel stabilizer system is provided. The fuel stabilizer system includes a fuel additive storage unit that stores fuel stability fluid. A fuel stability fluid supply system supplies fuel stability fluid from the fuel additive storage unit to a fuel storage unit. A control module estimates an age of fuel in the fuel storage unit and selectively controls the fuel stability fluid supply system to supply fuel stability fluid to the fuel storage unit based on the age of the fuel.

Abstract: A coated seal for sealing parts in a vehicle engine is disclosed herein. The seal includes a seal body portion including glass fiber-filled polytetrafluoroethylene, carbon-filled polytetrafluoroethylene, molybdenum disulfide-filled polytetrafluoroethylene, bronze-filled polytetrafluoroethylene or combinations thereof; and a coating portion including either expanded polytetrafluoroethylene, carbon-filled polytetrafluoroethylene, or combinations thereof. A method of using a coated seal in a vehicle engine is also disclosed herein. A system to achieve decreased friction, decreased noise, and improved wear in injector seals in a vehicle engine is also disclosed herein.

Abstract: A cylinder head assembly for an internal combustion engine and its method of manufacture is disclosed. The cylinder head assembly includes a cylinder head having a combustion chamber and a port opening into the combustion chamber. An insert pocket is circumferentially disposed about the port and is configured to receive a valve seat therein and to define a seam therebetween. A seal, comprising displaced cylinder head material disposed across the seam, seals the seam against the ingress of contaminants.

Abstract: An evaporative emissions system may include a first passage selectively providing fluid communication between a fuel vapor region of a vehicle fuel reservoir and an engine air intake system, a second passage in fluid communication with the fuel vapor region and ambient air, and a filter assembly. The filter assembly may be impermeable to at least one of oxygen and hydrocarbons and may be located in the second passage between the fuel vapor region and ambient air. The filter assembly may prevent the at least one of oxygen and hydrocarbons from traveling between the fuel vapor region and ambient air.

Abstract: A cylinder head for an internal combustion engine comprises a combustion chamber/face, a port opening into the combustion chamber/face and an insert pocket circumferentially disposed about the port and configured to receive a valve seat insert therein. A carbon layer is disposed between the insert pocket and the valve seat insert and is configured to prevent corrosion of the insert pocket caused by exposure to alcohol based fuels such as ethanol.

Abstract: Biofuels suitable for use in an internal combustion engine contain ethanol and are denatured with a performance-enhancing component. The performance-enhancing denaturant component includes an organic ingredient selected from the group consisting of friction modifiers, lubricity enhancers, anti-oxidants, and combinations thereof. An internal combustion engine fueled by such a biofuel has improved engine performance, including: increasing lubricant oil lubricity, reducing lubricant oil degradation, increasing engine component durability, and/or combinations thereof. In certain aspects, methods of increasing fuel economy are provided. The present disclosure also provides methods of formulating such biofuels.
