摘要:
A service station is provided with a plurality of vehicle servicing islands including liquid fuel blending pumps for dispensing and blending fuel components from underground storage tanks for refueling standard gasoline engine driven vehicles, standard diesel engine vehicles, vehicles with engines requiring dual fuels, vehicles with HCCL engines require low octane gasoline blended with standard diesel fuel, and fuel cell powered vehicles having onboard reformers. Other service islands include pumps for dispensing compressed hydrogen to fuel cell powered vehicles that do not include onboard reformers. In addition, service islands are provided for recharging the batteries of pure electric powered vehicles. A service station is further provided with a wireless communicator for receiving signals indicative of a vehicle's fuel requirements and transmitting signals to direct the vehicle to a service island capable of servicing the vehicle.
摘要:
The invention provides methods that expand the operating envelope of advanced combustion engines during operation in an advanced combustion mode by supplying an engine cylinder during operation in the advanced combustion mode with fuel-alcohol blends, e.g. gasoline-alcohol blends. In methods of the invention, fuel-alcohol blends combust efficiently over a wide range of engine loads, and the need for EGR, VVT, NVO, rebreathing, or multiple fuel injection is either reduced or eliminated.

Diesel fuels which have good ignition qualities, good combustion emission performance and good low temperature characteristics are characterized by a cetane number of at least 45, a total aromatics content of 10 to 15 wt. pct., a polynuclear aromatics content of less than 11 wt. pct., a sulfur content of not more than 50 ppmw, a total nitrogen content (from all sources) of not more than 100 ppmw, and excellent low temperature flow properties as manifested by a pour point not higher than -12.degree. C. and a cloud point not higher than -10.degree. C.
