4) Fuel Injection During CDPF Regeneration
The injection method in D20DTR engine has three steps;
Pilot injection, Main injection, Post injection
Post injection ▶
The post injection is the injection process after main injection and consists of ‘After injection”,
“Post 1 injection” and “Post 2 injection”. All of post injections are to reduce the PM and
harmful exhaust gas. The post injection does not make the actual output. The post injection activates
the fuel by injecting the fuel to the incompletely combusted gas after primary combustion. Through the
process, the PM and smoke in the exhaust gas could be reduced. There are totally 7 injections as
shown in the figure. However, all of 7 injections are not performed during driving because it decreases
the fuel economy. Totally 5 injections can be performed in one cycle.
