摘要： PROBLEM TO BE SOLVED: To improve the fuel consumption of an internal combustion engine equipped with a switchable suction type variable valve device capable of changing over a two-valve variable state that working angles of two suction valves are made variable and a single valve minor working angle state that a working angle of one suction valve is made smaller than that of the other suction valve.
SOLUTION: In a high-load region with torque equal to or larger than T1 and in a low-load region where the torque is lower than T2, the stoichiometric two-valve variable mode is introduced in which theoretical air-fuel ratio combustion takes place in the two-valve variable state. In the low-load region where the torque is lower than T1 and equal to or larger than T2, the two modes may be introduced, i.e. either a lean single-valve minor working angle mode in which lean burn takes place in the single-valve minor working angle state or an EGR single-valve minor working angle mode in which external EGR is conducted in the single-valve minor working angle state.

摘要： PROBLEM TO BE SOLVED: To provide a fuel reforming device capable of further accurately determining properties of fuel stored in a reforming fuel storing means.
SOLUTION: An ECU 60 is provided with a torque difference change rate determining portion determining the properties of reforming fuel stored in a reforming fuel tank 54 from the change rate of difference between estimated torque and actual torque of an engine. Therefore, the properties of the fuel supplied to a reforming catalyst can be determined. When the reforming fuel having properties except required one is supplied into the reforming catalyst 32, the reforming catalyst 32 is deteriorated and the producing amount of reforming gas is reduced, so that there is a risk of reducing the actual torque of the engine 1. Therefore, by checking the change rate of the difference between the estimated torque and the actual torque of the engine 1 when the reforming catalyst 32 ideally functions, the properties of the fuel supplied into the reforming catalyst 32 can be determined. Consequently, the properties of the fuel stored in the reforming fuel tank 54 as the reforming fuel storing means can be further accurately determined.

摘要翻译：解决的问题：提供能够进一步精确地确定存储在重整燃料存储装置中的燃料的性质的燃料重整装置。解决方案：ECU60设置有转矩差变化率确定部分，根据发动机的估计转矩和实际转矩之差的变化率确定重整燃料箱54中储存的重整燃料的性质。因此，可以确定供给重整催化剂的燃料的性质。当具有除所要求的特性的重整燃料供给到重整催化剂32中时，重整催化剂32劣化并且重整气体的产生量减少，从而存在降低发动机1的实际扭矩的风险。因此通过在重整催化剂32理想地起作用时，通过检查发动机1的推定转矩与实际转矩之差的变化率，可以确定供给到重整催化剂32中的燃料的性质。因此，可以进一步精确地确定作为重整燃料存储装置的重整燃料箱54中储存的燃料的特性。版权所有（C）2009，JPO＆INPIT
