摘要： PROBLEM TO BE SOLVED: To provide a method of operating an engine having a cylinder operable in an HCCI mode, which can attain both improvement in fuel economic property by charged air leaner than stoichiometric one and effectiveness of catalyst which tends to deteriorate according to this at high level. SOLUTION: The method comprises steps of: injecting a first amount of fuel into the cylinder (216); auto-igniting a first mixture of air and first amount of fuel by compressing the first mixture (218); injecting a second amount of fuel into the cylinder after auto-igniting the first mixture (222); burning a second mixture of the second amount of fuel and gasses from auto-ignition of the first mixture (224); holding an intake valve of the cylinder closed between auto-igniting the first mixture and burning the second mixture (218-224); and exhausting the burned second mixture (226).

摘要： PROBLEM TO BE SOLVED: To enhance the detection accuracy of a synchronization error between an engine control module (ECM) and valve control unit (VCU). SOLUTION: A control system of a multiple cylinder engine (10) equipped with electric valve actuation (51) comprises at least one cylinder (30) containing an engine cylinder valve (52), a second controller (140) operably coupled to the engine cylinder valve (52) so as to adjust at least one piece of valve opening timing and valve closing timing of the engine cylinder valve (52), and a first controller (12) which is connected with the second controller (140) via a first link (206) and second link (208) and which transmits an engine position indication signal to the second controller (140) via the first link (206) and receives a status signal from the second controller (140) via the second link (208) so as to output a synchronization degradation signal in response to a synchronization error between the engine position indication signal and status signal.

摘要： PROBLEM TO BE SOLVED: To provide a method of controlling an engine capable of enhancing the robustness and reproducibility of transition while suppressing the occurrence of defects during the transition in operation modes between an SI mode and an HCCI mode.
SOLUTION: During the transition from a spark ignition (SI) mode to a premixed compression ignition (HCCI) mode, an engine is operated with a predetermined overlap between the opening period of an intake valve 52 and an opening period of an exhaust valve 54 in the SI mode before the transition. The overlap is changed over to a negative overlap according to the request of transition, and the opening timing and the closing timing of the intake valve 52 are retarded by different amounts, respectively, and the ignition timing is retarded. The negative overlap is further enhanced, and the premixed compression ignition mode is performed.
