EXHAUST PURIFICATION DEVICE FOR INTERNAL COMBUSTION ENGINE |
摘要 |
An exhaust gas purification apparatus of an internal combustion engine includes: an NH 3 generating catalyst which generates NH 3 from NOx and H 2 at a rich air-fuel ratio; an in-cylinder injection valve which injects fuel into a cylinder; and a control apparatus which, when setting a rich air-fuel ratio, sets a timing of fuel injection from the in-cylinder injection valve to a second half of a compression stroke when a temperature of the NH 3 generating catalyst is within a first prescribed range and sets a timing f of fuel injection from the in-cylinder injection valve to a first half of an intake stroke when the temperature of the NH 3 generating catalyst is within a second prescribed range that is a higher temperature range than the first prescribed range. |
