Fuel Injection Control

CATALYST-HEATING COMBUSTION 

Catalyst-heating combustion is a combustion method.

Right after a start with the engine coolant temperature between - 12°C (10.2°F) to 40°C (104°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.
