摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of stabilizing combustion, and capable of improving exhaust emission, by suitably restraining the direct inflow of blow-by gas in a combustion chamber via a piston clearance.
SOLUTION: In starting control of an engine 10 when opening of a throttle valve 45 becomes small (negative pressure in the combustion chamber 31 becomes large), whether or not a vaporized fuel quantity in the blow-by gas falls within an allowable range is determined from an injection quantity correction quantity (the fuel dilution ratio), the present oil temperature and a soak time in idle operation just before stopping the engine last time. When a determination is made that the vaporized fuel quantity in the blow-by gas exceeds the allowable range, control is performed for adjusting the suction air volume by blowing back intake air by changing the valve closing timing of an intake valve 35 to the ignition timing delay side in response to its control together with the control for fully opening the opening of the throttle valve 45.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation device performing EGR so as to restraining the generation of CO and smoke while restraining the generation of NOX when lean burn is carried out.
SOLUTION: The exhaust gas recirculation device is applied for a gasoline engine and provided with a means for implementing an internal EGR control to control a residual exhaust gas amount in a cylinder by controlling an opening/closing characteristic of at least one of an intake valve 3 and an exhaust valve 5, an exhaust gas recirculation passage 6 for allowing at least part of exhaust gas to flow into an intake passage, and a means having a control valve 7 regulating a flow rate of the exhaust gas passing through the exhaust gas recirculation passage 6 and implementing an external EGR control to control an intake exhaust gas amount. In the case of implementing either of the EGR controls while engine performs combustion with an air fuel ratio larger than a theoretical air fuel ratio, the internal EGR control is implemented for the air fuel ratio smaller than a prescribed value and switched to the outer EGR control for the air fuel ratio not less than the prescribed value.

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 ensure a large quantity of exhaust gas recirculation while restraining a pumping loss. SOLUTION: At the time when a large amount of EGR is required (YES at Step 104), a valve overlapping amount, back pressure and intake pipe pressure are measure at Step 108, a difference between the back pressure and intake pipe pressure is computed at Step 110, and an exhaust shutter is controlled in synchronization with the valve overlapping amount so as to have an opening by which a differential pressure for a specified EGR amount is obtained, at Step 112. Otherwise, in an internal combustion engine with an airstream control valve, a downstream end of outer EGR pass is connected to a downstream intake port, and in the case of a large amount of required EGR the opening of airstream control valve is made small.

摘要： PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine which reduces an NOx present in an suction passage before the operation of the internal combustion engine is stopped, and prevents the deposit from occurring in the suction passage after the operation stop. SOLUTION: An ECU judges whether a shift lever is in an N position or a P position (step S110). When the shift lever is in the N position or P position, a valve overlap period is eliminated and the valve closing period of the suction valve is set before the bottom dead center of the engine (step S150) so that already burnt gas is blown back to a suction port. The PCV valve is in a valve closing state (step S160), so that blow-by gas is suppressed from flowing into the suction port. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve characteristic control device for an internal combustion engine capable of effectively suppressing generation of smoke in a cold engine condition under which adhesion of liquid fuel to an inner wall of a combustion chamber increase.
SOLUTION: Premixed combustion during which vaporized fuel burns under a condition of premixed with air occurs at first as combustion of fuel during a predetermined period from beginning of engine start to a time when liquid fuel adheres the inner surface if the combustion chamber 3 in the cold engine condition. After that, diffusion combustion during which liquid fuel adhering the inner wall of the combustion chamber 3 is vaporized by combustion heat or the like during above mentioned premixed combustion and burns occurs. Open timing of an exhaust valve 21 is made close to start timing of diffusion combustion. Consequently, since the exhaust valve 21 opens to reduce temperature and pressure in the combustion chamber 3 and to quench flames in the combustion chamber 3 at transition from premixed combustion to diffusion combustion in the combustion chamber 3, duration of diffusion combustion causing generation of smoke is very short even if diffusion combustion occurs.

摘要： PROBLEM TO BE SOLVED: To enable a large amount of EGR in a cylinder direct injection engine with a supercharger. SOLUTION: In a cylinder direct injection engine directly injecting fuel such as gasoline into the inside of a cylinder, the post-treatment of NOx becomes difficult because of burning a lean mixture, and conducting a large amount of EGR is needed for reducing the NOx. If a supercharger is provided on the cylinder direct injection engine so as to increase output, the pressure of an intake passage is higher than the pressure of an exhaust passage, so that EGR becomes impossible. For this reason, internal EGR is conducted by changing valve timing of an intake valve and a exhaust valve, or providing a exhaust shutter in the exhaust passage to let exhaust gas remain in the cylinder or the intake passage. When external EGR is conducted, an EGR port at an end of an external EGR pipe is opened between the supercharger and a pressure control valve provided upstream to the supercharger, and an ordinarily throttle valve is provided downstream to the supercharger.
