Filed:

Dec 12, 2005
Appl. No.:

11/301199
Inventors:

Alan M. Horowitz - Cherry Hill NJ, US
Walter Weissman - Basking Ridge NJ, US
Charles Hall Schleyer - Lincoln University PA, US
Assignee:

ExxonMobil Research And Enginnering Company - Annandale NJ
International Classification:

B65B 1/30
US Classification:

141 94, 141104, 700239, 340933, 3409951, 34099519, 34099527
Abstract:

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.

Filed:

Apr 16, 2010
Appl. No.:

12/799056
Inventors:

Lisa I. Yeh - Marlton NJ, US
Jeffrey H. Farenback-Brateman - Cherry Hill NJ, US
Charles H. Schleyer - Lincoln University PA, US
Mike T. Noorman - Cinnaminson NJ, US
Assignee:

ExxonMobile Research and Engineering Company - Annandale NJ
International Classification:

F02B 13/00
US Classification:

123575
Abstract:

The invention provides enriched fuels and methods that expand the operating envelope of an advanced combustion engine during operation in an advanced combustion mode (e.g. HCCI mode). Enriched fuels and methods of the invention facilitate efficient combustion over a wide range of engine loads, and the need for EGR, VVT, NVO, rebreathing, or multiple fuel injection is either reduced or eliminated.

Appl. No.:

13/380557
Inventors:

Paul W. Bessonette - Deptford NJ, US
Charles H. Schleyer - Lincoln University PA, US
Kevin P. Duffy - Deeping Gate, GB
International Classification:

C10L 1/10
C10L 1/12
C10L 1/16
C10L 1/182
US Classification:

44307, 44451, 44458, 585 14
Abstract:

A fuel composition for a homogenous charge compression ignition engine includes a combination of a gasoline fuel and a diesel fuel, the combination having a derived cetane number of from about 19.9 to 45 as determined in accordance with ASTM method D6890. A method for making the fuel composition provides for blending presently available gasoline fuel and diesel fuel together in a ratio to obtain the desired fuel composition.

Filed:

Feb 16, 2001
Appl. No.:

09/784885
Inventors:

Charles Hall Schleyer - Lincoln University PA, US
International Classification:

C10L 1/04
US Classification:

585 14, 208 14, 208 15, 208 16, 208 17
Abstract:

Total combustion and evaporative emissions from gasoline pump fuels can be controlled with total emissions no higher than those currently allowed by the addition of an evaporative factor such as RVP to the model predicting emissions, based on a number of considerations including the sensitivity of emission parameters (toxics, hydrocarbons, CO and NOx) as related to the variables in the predictive model (oxygenate content, sulfur, T, T, aromatics, olefins, benzene and RVP). The present pump gasolines will normally have compositions including Tno greater than 140 F. , Tno greater than 330 F. , RVP no greater than 7 psi and usually lower and sulfur no greater than 50 ppmw. Oxygenates may be eliminated, permitting Tvalues to increase which is not unfavorable from the viewpoint of total emissions provided other parameters are held within specified limits. Aromatics, olefins and benzene are normally held to maximum of 35, 10 and 1 vol % respectively to achieve satisfactorily low total emissions.
