  • Patent number: 10393071
    Abstract: Methods and systems are provided for conducting an evaporative emissions test diagnostic on a vehicle fuel system and evaporative emissions control system during engine-on conditions. In one example, a first fuel vapor storage device is separated from a second fuel vapor storage device by a one-way check valve, thus preventing loading of the first fuel vapor storage device during conditions such as refueling operations, diurnal temperature fluctuations, or from running-loss vapors from a vehicle fuel tank. In this way, the evaporative emissions test diagnostic may be conducted during a cold-start event where an exhaust catalyst is below a predetermined threshold temperature required for catalytic oxidation of hydrocarbons in the engine exhaust, without increasing undesired exhaust emissions.

When the catalytic device (35) is not in an activated state and a vehicle is traveling, the PCM (60) is configured to perform: a fuel injection control to inject fuel such that a homogeneous fuel-air mixture can be formed in a combustion chamber (11) of an engine (10) so as to generate a homogeneous combustion; an intake air amount control to increase intake air amount; and an ignition control to retard ignition timing from a reference ignition timing. In addition, the PCM (60) is configured to vary ignition timing retard amount corresponding to a difference between the ignition timing retarded by the ignition timing control and the reference ignition timing, in accordance with engine speed and/or engine load.

  • Patent number: 10378466
    Abstract: The control system of the internal combustion engine comprises a control part controlling an air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst. The control part alternately sets a target air-fuel ratio between a rich air-fuel ratio and a lean air-fuel ratio and controls the air-fuel ratio of the exhaust gas so that an output air-fuel ratio of the air-fuel ratio sensor becomes the target air-fuel ratio. The control part corrects the output air-fuel ratio of the air-fuel ratio sensor so that when a scavenging occurs, the air-fuel ratio of the exhaust gas changes to a rich side more than an amount of deviation expected to occur in the output air-fuel ratio due to the occurrence of the scavenging. The control part increases a lean degree of the target air-fuel ratio when the scavenging occurs compared with when the scavenging does not occur.

  • Patent number: 10287937
    Abstract: An exhaust system for an engine has a volume element such as a muffler or a silencer. First and second exhaust pipes are connected as dual exhaust pipes upstream of or downstream of the volume element. The first exhaust pipe has a first length (L1).
