Abstract
A method of reducing NOx in the exhaust of a diesel engine having at least one combustion chamber by introducing NH3 into the diesel engine prior to a combustion event, at least some of the NH3 injected reducing the amount of NOx in the exhaust of the diesel engine, whereby the exhaust will contain an amount of NOx that is less than if no injection of NH3 was used, and will also contain an amount of NH3 that is less than the amount injected into the diesel engine, the rest of the NH3 being consumed during the combustion event and the reduction of NH3.
Claims10
A method of reducing NOx in the exhaust of a diesel engine having at least one combustion chamber comprising:
- introducing a controlled quantity of NH3 into the diesel engine prior to a combustion event;
- at least some of the NH3 injected reducing the amount of NOx in the exhaust of the diesel engine, whereby the exhaust will contain an amount of NOx that is less than if no injection of NH3 was used, and will also contain an amount of NH3 that is less than the amount injected into the diesel engine, the rest of the NH3 being consumed during the combustion event and the reduction of NH3.
A method of reducing NOx in the exhaust of a diesel engine having at least one combustion chamber comprising:
- introducing a controlled quantity of NH3 into the diesel engine prior through an air intake manifold of the diesel engine through an air intake manifold of the diesel engine to a combustion event;
- at least some of the NH3 injected reducing the amount of NOx in the exhaust of the diesel engine, whereby the exhaust will contain an amount of NOx that is less than if no injection of NH3 was used, and will also contain an amount of NH3 that is less than the amount injected into the diesel engine, the rest of the NH3 being consumed during the combustion event and the reduction of NH3;
- and wherein
- the exhaust of the diesel engine is also passed through an NOx catalyst for further NOx reduction.
