Abstract

One concept relates to power generation system, comprising a diesel engine, an exhaust manifold, a turbocharger, and an exhaust line in which are configured a fuel reformer and a LNT. A fuel injector is configured to inject fuel into the manifold upstream of the turbine. The high temperatures upstream of the turbine cause the fuel to crack into smaller molecules, releasing heat and providing a boost to the turbocharger. The fuel injected into the manifold also undergoes intense mixing as it passes through the turbocharger. Injecting fuel in this manner provides several benefits for reformer operation. Another concept relates to a manifold fuel injector used to provide fuel for heating a DPF.
