Title:
DIESEL ENGINE
Document Type and Number:
Japanese Patent JP2003065121
Kind Code:
A
Abstract:
To provide technique capable of promoting warming-up of catalyst while suppressing HC concentration in exhaust gas.
During warming-up period of catalyst, an injection amount ratio of pilot injection is set to a higher value than an injection amount ratio of pilot injection performed in a normal operation condition after the warming-up period. Moreover, injection time of main injection during the warming-up period is set to the time more delayed than injection amount time of main injection performed in a normal operation condition after the warming-up period.
