摘要： PROBLEM TO BE SOLVED: To optimize the relationship between the injection start time and injection period of fuel in cold starting.
SOLUTION: When a cooling water temperature Tw is less than a threshold value Twth in cold starting in the step of executing a start injection control, an ECU 100 executes a cold starting process. In this process, a discharge stroke rotation speed Rex, an intake stroke rotation speed Rin, and a compression stroke rotation speed Rcp are estimated by referring to a map in a first cycle in starting based on an explosion order, the cooling water temperature Tw, and a fuel property Fp for each cylinder. The ECU 100 provides a relational expression (1) of Ts=a×Cx+b which defines the relationship between an injection start crank position Cx and injection period Td of the fuel based on each of these rotational frequencies, calculates the injection start crank position Cs for minimizing a fuel consumption amount and the injection period Td corresponding to the injection start crank position Cs based on the relational equation, and drives and controls an injector 214.

摘要： PROBLEM TO BE SOLVED: To suppress the generation of smoke when a spark ignition type internal combustion engine is started when an engine temperature is low. SOLUTION: An electronic control unit (ECU) 35 corrects an ignition timing during cranking to be slower than that at a compression top dead point when the engine temperature is low, in accordance with the engine temperature of the spark ignition type internal combustion engine 11 or engine information corresponding thereto. In particular, the ignition timing is corrected to be much slower as the engine temperature is lower. It is corrected to be slower in this way to make combustion into a slower pace and suppress a tendency toward a higher temperature in a combustion site with the rise of a combustion temperature, resulting in smoke to hard to generate. Furthermore, it is effective to correct the ignition timing to be much slower with a lower engine speed (cranking rotating speed) during cranking or grant an air stream to a mixture in a cylinder 12 with the turn of an air stream control valve 41 to closed when the ignition timing is corrected.

摘要： PROBLEM TO BE SOLVED: To improve a method of controlling a fuel injection device for reducing an exhausted smoke amount at the time of starting in a direct injection spark ignition internal combustion engine.
SOLUTION: To set an injection timing guard for assuring a fuel vaporizing time on the spark-retard angle side of an intake bottom dead center, smoke at the time of starting generated due to adhesion of fuel onto the inside wall surface of a cylinder is reduced by setting the injection timing guard for suppressing fuel wet on the spark-advance and spark-retard angle sides of the intake bottom dead center and setting that range as an injectable range and the other range as an injection-prohibited area. Since fuel is not injected in the period in which the top face of a piston nears the injection nozzle of a fuel injection nozzle, the adhered amount of fuel wet can be reduced. When a requested fuel injection amount is too large to fill only by a feed pressure in the injectable range, an injection pressure is increased beyond the feed pressure to increase an injection rate.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for a cylinder injection internal combustion engine, suitably suppressing the increase of combustion changes even when performing Atokinson cycle through the cylinder injection internal combustion engine.
SOLUTION: The cylinder injection gasoline engine 1 has a variable valve timing mechanism 19. It is configured to perform closure slowing control (Atokinson cycle) of an intake valve 12 whose closing timing is set to be slower than that at an intake bottom dead center of a piston 5. On request of execution of the closure slowing control of the intake valve, a control device 50 controls the injection pressure of a fuel to be injected from a fuel injection valve 35 to be higher than in no-execution of the closure slowing control of the intake valve or controls an injection timing for the fuel to be injected from the fuel injection valve 35 to be faster than in the no-execution of the closure slowing control of the intake valve.
