Claim 0:
1. A diesel engine comprising:
a combustion apparatus for combustion of diesel fuel with an oxidizer,
a Selective Catalytic Reduction (SCR) device for receiving exhaust from the combustion apparatus, the Selective Catalytic Reduction (SCR) device is configured for catalyzing conversion of nitrogen oxides in the exhaust into nitrogen and water,
an air feed for feeding air into the combustion apparatus,
an oxidizer feed for feeding hydrogen into the combustion apparatus,
a temperature sensor configured to sense a temperature of the exhaust, and
a control unit configured to control the feeding of hydrogen into the combustion apparatus,
wherein the control unit is configured to control the feeding of hydrogen into the combustion apparatus sufficient to reach a temperature in the exhaust of at least about 270° C.,
wherein the oxidizer feed is a part of an injection unit, and
wherein the injection unit is adapted for mixing hydrogen and air from the air feed prior to feeding to the combustion apparatus via an inlet.
