Title: Accumulator fuel injection device
Inventor: KAWASE KENJI
IPC: F02D41/40
Filed: 2001-01-19
Abstract: PROBLEM TO BE SOLVED: To increase the accuracy of controlling the time to start the injection of an injector during after-injection when three-stage injection (pilot, main, and after-injection) is carried out for a specific cylinder of a diesel engine during one cycle (one stroke) of the engine. SOLUTION: A method of computing the time to start conduction for after- injection includes newly setting, for after-injections, a two-dimensional map for calculating the time of delay in the end of main injection, TDEM, from a common-rail pressure NPC and a conduction period TQM for the main injection, and a two-dimensional map for calculating the time of delay in the start of after-injection, TDA, from the common-rail pressure NPC and an after- interval TINTA. If conduction for after-injection is ordered, the two-dimensional maps are searched to accurately compute the time to start after-injection. Thus, since the accuracy of controlling the time to start injection of the injector during after-injection can be increased, a desired injection-rate waveform can be produced.
