Abstract: PROBLEM TO BE SOLVED: To certainly start an engine. SOLUTION: When the engine does not completely explode within a predetermined time after engine start by driving a starter motor and a fuel pump (S100 to S104), the driving of the fuel pump is stopped for a predetermined time (for example, 3 sec) and is restarted after a predetermined time (S106 to S110). The driving of the fuel pump is temporarily stopped because repeating of driving and stopping of the fuel pump frequently allows removal of a foreign matter even when the foreign matter intrudes into the fuel pump to cause a starting failure. Thus, the fuel pump is normally driven, so that the engine is started further certainly. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide an ignition timing control device of a hybrid car that prevents system down because of a deterioration of combustion during controlling of a catalyst warming-up after cold start. SOLUTION: When an output of a motor generator during controlling of a catalyst warming-up exceeds a limit value of motor output (NO in S110), the amount of lag (easbd) is reduced (S140). That is, when an engine torque becomes negative and the motor generator brings out battery power in order to control an engine speed to be a target value, the control device reduces the amount of lag. Accordingly, stable combustion is assured. Also, the device does not let the motor generator bring the battery power out by reducing the amount of lag, the power can be prevented from being taken out from the battery after cold start.

Abstract: PROBLEM TO BE SOLVED: To control an engine actuation characteristics changing means, capable of changeably controlling an intake compression ratio and locking such an actuation condition as to increase the intake compression ratio by a locking means, so as to cope with generation of undesirable locking for intake compression ratio increasing. SOLUTION: It is determined if the actuation condition is locked by the locking means when the actuation condition to increase the intake compression ratio is not to be formed in the engine actuation characteristic changing means or not. When it is determined as locked, countermeasures for reducing uncomfortableness due to increase of engine vibration by the locking are taken.

Abstract: PROBLEM TO BE SOLVED: To rapidly change sure engine operational characteristics and save the power consumption for the operation required for the change by reasonably changing the characteristics by an engine operational characteristic changing means, in changing the characteristics at non-operation of an engine in such a way that the intake compression ratio is increased before the cranking when the engine is in a cold state.
SOLUTION: Displacement of the means to a predetermined position is carried out by the control of drive force (the intensity of the driving force and its operational time).

Abstract: PROBLEM TO BE SOLVED: To provide sufficient information on start of an internal combustion engine of an automobile and to prevent a driver from feeling frustration and a sense of incongruity due to delay in cranking start even if cranking is started with some preparation such as increase in intake air compression ratio when a command to start the engine is given at cold start in starting the internal combustion engine. SOLUTION: A signal means is provided for issuing an engine starting signal to inform the driver that the engine is being started by an engine start command when starting the internal combustion engine of the automobile according to the engine start command.

Abstract: PROBLEM TO BE SOLVED: To improve a property of engine exhaust in a period when an engine is started under its cold condition and where an effective exhaust emission control function is not effectuated yet in a catalytic converter, by making the best use of a characteristic of a hybrid vehicle combined with engine drive and motor drive. SOLUTION: The engine is operated stably by a warming-up target output Lestart, while output requirement to the vehicle is mainly entrusted to a motor and its fluctuation is exclusively to the motor, until the first stage catalytic converter provided just in a downstream of an exhaust manifold reaches to a prescribed warming-up degree T1. The engine is operated increasing an output increasing speed in response to requirement, while limiting the output increasing speed within an increment ΔLelimit or an increase rate Kelimit, until the second stage catalytic converter reaches to a prescribed warming-up degree T2 after the first stage catalytic converter reaches to the prescribed warming-up degree, or until a time Co estimated as establishment of the condition therein is expected passes, and an amount of fuel is thereafter increased or decreased according to control calculation based on an input data to be operated.
