Catalyst-heating Combustion
Catalyst-heating combustion is a combustion method.
Right after a start with the engine coolant temperature between -12 deg.C (10.2 deg.F) to 40 deg.C (104 deg.F), the catalyst warm-up is accelerated by this combustion.
Homogeneous Combustion
Homogeneous combustion is a combustion method that fuel is injected during intake process so that combustion occurs in the entire combustion chamber, as is common with conventional methods.
As for a start except for starts with the engine cold, homogeneous combustion occurs.
