IPC: F02D45/00
Filed: 2003-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To secure stable combustion performance not influenced by properties of fuel in a cylinder injection type engine.  <P>SOLUTION: In the case where used fuel is determined to be heavy fuel (fuel property is heavy) at operation in a layered combustion mode, the base compression stroke injection timing ACO corresponding to the standard fuel is corrected by timing advance in a range falling the compression stroke to set the final compression stroke injection timing AC. On the other hand, in the case where used fuel is determined to be heavy fuel at operation in a homogeneous combustion mode, the base intake stroke injection timing AIO corresponding to the standard fuel is corrected by timing lag in a range falling the intake stroke to set the final intake stroke injection timing AI. Thus, the amount of time (time for atomizing fuel) from when fuel is injected into the cylinder until ignition is performed is enlarged so that even if heavy fuel can be enough atomized to form air fuel mixture in suitable timing corresponding to each combustion mode.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
