Converting a production 6-cylinder Heavy Duty Engine to Dual-fuel mode operation using supervisory calibration and manifold injection

Carbon dioxide emissions from heavy-duty vehicles can be reduced by converting, or retrofitting, conventional diesel engines into “dual fuel” mode operation using hydrogen and fuel. Conversion involve small relatively cheap changes to design, thereby allowing a engine fuelled either conventionally, fuel (direct injection), in conjunction with (indirect injection – “fumigation”) the intake manifold. We evaluate conversion of production, 6-cylinder 12.7L truck run dual mode. Commercially viable conversions would permit, short term, no-regrets ‘pump priming’ pricing, storage distribution infrastructure which, medium could also benefit development hydrogen-powered inshore marine vessels trucks powered by, for example, cells. The aim this work was establish limitations advantages pursuing an in-production heavy duty least engine.
