  • Patent number: 10513257
    Abstract: An ignition switch is turned on, and when an abnormality is detected in any of electronic control instruments or sensors, real failure is established, and a fail-safe process is performed. After a lapse of a predetermined period from the establishment of the real failure, fault determination is established, a failure level is sent, and a hybrid fail-safe process is performed. Then, when the abnormality is eliminated, the real failure is not established, and the fail-safe process of an engine is finished. Then, when the ignition switch is turned off and then again turned on, sending of the failure level to a hybrid control unit is stopped, and the hybrid fail-safe process is finished.

  • Patent number: 8360021
    Abstract: Disclosed is a variable valve gear comprising a camshaft phase change mechanism, which variably controls a phase of an intake cam with respect to a crankshaft, and a variable valve lift mechanism, which changes an opening timing of an intake valve more than a closing timing and basically continuously varies a lift and an open period of the intake valve. The lift and the open period are set lest the intake valve interfere with a piston of an engine, with the phase controlled to be most advanced by the camshaft phase change mechanism and the lift controlled to be maximal by the variable valve lift mechanism.

  • Patent number: 8205585
    Abstract: In a variable valve gear for an internal combustion engine provided with a camshaft phase change mechanism for variably controlling opening and closing timings of an intake valve, the camshaft phase change mechanism and a variable valve lift mechanism are controlled so that the closing timing of the intake valve is advanced beyond a predetermined range T1 including a bottom dead center when a load L of the internal combustion engine is less than a first predetermined value L1 and that the closing timing of the intake valve is delayed beyond the predetermined range T1 when the load L of the internal combustion engine is not less than the first predetermined value L1.

  • Patent number: 8061316
    Abstract: An internal combustion engine includes: a variable valve train mechanism, configured to receive a cam displacement of an inlet cam so as to vary a driving output for driving an inlet valve continuously from a maximum valve lift to a minimum valve lift so as to match the driving output with a running condition of the internal combustion engine; and a control part, configured to control the variable valve train mechanism so as to set a valve lift of the inlet valve to a starter valve lift when starting the internal combustion engine in a cold state. The starter valve lift is formed so that a valve opening period of the inlet valve is set to encompass an overall area of an induction stroke period of the internal combustion engine from a top dead center to a bottom dead center of the induction stroke period.

  • Patent number: 6539916
    Abstract: In a direct injection type engine, capable of switching an injection mode between a compression stroke injection mode for injecting fuel mainly during a compression stroke and an intake stroke injection mode for injecting fuel mainly during an intake stroke; a fuel injection starting timing in the intake stroke is corrected to a retard side as the temperature relating to an internal combustion engine, detected as a parameter representing the tendency of fuel to adhere to the inside of the internal combustion engine, becomes lower. If a required fuel injection volume cannot be injected during the intake stroke injection mode in the corrected fuel injection timing, a timing for injecting remaining fuel to satisfy the required fuel injection volume during a compression stroke following the intake stroke in one combustion cycle is determined. The injection of the fuel is controlled according to the corrected fuel injection timing.
