Stoichiometric air-fuel ratio control during transient operation requires an accurate estimate or measurement of the instantaneous air flow rate in an engine. Two methods are commonly used for ...

The increasing requirements imposed on diesel engine manufacturers have required the study of fuel injection system faults and the development of means to eliminate them. Until now, improved injection ...

Well test analyses that include the first and second derivative of pressure plotted on a semilog scale can help detect radial flow. Plots of pressure data from short transient tests often fail to ...

Application of multi-fractured horizontal well bores to the recovery of oil from ultra-low permeability reservoirs presented a difficult paradigm shift for operators, service providers, and the ...
