HFI is based on the phenomenon of corona discharge.

Precise ignition timing
Enabler for alternative combustion processes, such as HCCI
Enabler for reduced mixture enrichment under full load
Combustion diagnostics by flame front detection

Management of the ignition energy by intelligent electronic control
Long single spark duration and high ignition energy

Auxiliary components such as the diesel exhaust fluid tank and standard fuel tank are now located under the cab instead of behind it on the frame.
