Patent ID: 8646435

Claim:
A method for substantially operating a diesel engine at stoichiometry, wherein the diesel engine includes a plurality of cylinders capable of operating in a succession of combustion cycles, the method comprising: receiving instruction for a first desired engine output, wherein the first desired engine output is generated using adaptive predictive programming; substantially unthrottling the air intake into a first subset of the plurality of cylinders during each of their respective working cycles while the diesel engine is in a first operational state corresponding to the first desired engine output, wherein the unthrottling substantially maintains the efficiency of the diesel engine by avoiding pumping loss; substantially regulating fuel delivery into to the first subset of the plurality of cylinders at substantially stoichiometric fuel levels during each of their respective working cycles while the diesel engine is in a first operational state corresponding to the first desired engine output, wherein the regulating fuel at substantially stoichiometric levels enables the control of NOx emissions via a three way catalytic converter; and substantially disabling fuel injection into to a second subset of the plurality of cylinders during each of their respective working cycles while the diesel engine is in the first operational state corresponding to the first desired engine output, wherein the ratio of cylinders in the first subset of cylinders and the second subset of cylinders corresponds to the first desired engine output.
