EXHAUST PIPE INJECTION CONTROL DEVICE

Title:

EXHAUST PIPE INJECTION CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/155584

Kind Code:

A1

Abstract:

Disclosed is an exhaust pipe injection control device that can optimally control the degree of EGR opening during DPF regeneration. The device is provided with a regeneration-time opening control unit (173) that controls the degree of EGR opening of the EGR device (123) during DPF regeneration. The device is provided with a regeneration-time opening map (172) that sets ahead of time the optimal degree of EGR opening of the EGR device (123) during DPF regeneration in response to the amount of fuel injection in an engine (101) and the rotational velocity of the engine. The regeneration-time opening control unit (173) controls the degree of EGR opening of the EGR device (123) referring to the regeneration-time opening map (172) with the rotational velocity of the engine and the amount of fuel injection in the engine (101), and performs exhaust gas recirculation.
