Patent number: 8954221Abstract: An emission deterioration notifying device includes a low fuel pressure determining unit, an emission deterioration notifying unit, and an electric control unit. The determining unit determines whether supply pressure of fuel supplied to an injector is in a low fuel pressure state, in which the supply pressure is lower than a predetermined threshold value. The notifying unit notifies that exhaust emission is deteriorating beyond its allowable range when it is determined that the supply pressure is in the low fuel pressure state. The control unit allows notification by the notifying unit at a time of injection control at which injection of fuel from the injector is allowed, and the control unit prohibits notification by the notifying unit or reduces the threshold value at a time of injection stop control at which injection of fuel from the injector is stopped.Type: GrantFiled: July 14, 2011Date of Patent: February 10, 2015Assignee: Denso CorporationInventor: Satoru Ohsaki

Patent number: 8788179Abstract: An emission deterioration informing device senses actual injection timing, at which fuel injection is actually performed from an injector. The device calculates a deviation amount of the sensed actual injection timing from target injection timing. The device has a warning light for informing deterioration of exhaust emission when the calculated deviation amount is larger than a predetermined threshold value. The device determines whether an operation state of an internal combustion engine is an impact state, in which the exhaust emission receives a predetermined influence or more from the deviation of the actual injection timing from the target injection timing. The device allows lighting of the warning light when the operation state is determined to be the impact state. The device prohibits the lighting of the warning light when the operation state is not determined to be the impact state.Type: GrantFiled: July 12, 2011Date of Patent: July 22, 2014Assignee: Denso CorporationInventor: Satoru Ohsaki
