摘要： PROBLEM TO BE SOLVED: To prevent undesired premature ignition and knocking due to high temperature of gas in a cylinder immediately after switching to two cycle operation from four cycle operation.
SOLUTION: When switching to premix compression self ignition two cycle operation from premix spark ignition four cycle operation is carried out, an exhaust valve 134 is opened for a long time or twice in a transition period to suck exhaust gas discharged to an exhaust port 16 once in a cylinder 142 again. Since temperature of exhaust gas discharged once and sucked in again via the exhaust valve 134 drops due to heat exchange, gas temperature in the cylinder during premix compression self ignition two cycle operation drops and undesired premature ignition and knocking do not occur.

摘要： PROBLEM TO BE SOLVED: To suitably improve ignition performance in compression-ignition diffusing combustion using a fuel with low-compression ignitability while avoiding the generations of exhaust emission, fuel consumption deterioration and lubricating failure in a multi-fuel internal combustion engine.
SOLUTION: The multi-fuel internal combustion engine is equipped with a piston 32 on whose top surface a cavity 32a is formed and a fuel injection valve 44 for injecting light oil and gasoline or a blended fuel of light oil and gasoline toward an inside of a combustion chamber 34. When a fuel injection is performed under the condition where the piston 32 is positioned between a -25 degrees CA posterior to an air intake top dead center and a 25 degrees CA posterior to the air intake top dead center, the fuel is prevented from running off the cavity 32a. Based on an ignition performance index value made for compression-ignition performance of the fuel introduced into the combustion chamber 34, when performing the compression-ignition diffusing combustion using gasoline, prior to the main injection, during a period of time elapsing from a 5 degrees CA posterior to the air intake top dead center to the 25 degrees CA posterior to the air intake top dead center, an control operation is performed so that an intake-stroke injection using gasoline is carried out.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating oil dilution control device of an internal combustion engine which can prevent the occurrence of the lubrication failure of the internal combustion engine or the like.
SOLUTION: The lubricating oil dilution control device of the internal combustion engine is provided with a piston, an oil jet, a means of controlling a lubricating oil injection amount, and the means of detecting the degree of dilution of the lubricating oil. The oil jet injects the lubricating oil toward the piston, and the means of controlling the lubricating oil injection amount controls the injection amount of the lubricating oil which is injected from the oil jet. The means of detecting the degree of dilution of the lubricating oil detects the degree of dilution of the lubricating oil which is diluted with fuel. The means of controlling the lubricating oil injection amount adjusts the injection amount of the lubricating oil from the oil jet in accordance with the degree of dilution of the detected lubricating oil. Because of this, the lubricating oil is heated more easily by the piston, and a fuel evaporation component which is contained in the fuel mixed with the lubricating oil evaporates. Thus the proportion of the lubricating oil to the mixture of the fuel and the lubricating oil can be increased. As a result, the lubricating oil of which the mixing amount of the fuel has decreased is made available for the lubrication of the internal combustion engine, thus the occurrence of the lubrication failure of the internal combustion engine or the like can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a control system for an internal combustion engine provided with a supercharger with an assist mechanism wherein antiknock quality and responsivity to supercharge are made favorably compatible with each other irrespective of variations in control which are caused by difference in individual parts and secular change in the supercharging system.
SOLUTION: An ignition-timing correction is made to a base ignition-timing which is predetermined on the basis of the knocking detection or predicted information. When a post-correction ignition-timing shows a value on the advance side of the base ignition-timing, a MAT power restriction coefficient K is corrected on (made to learn) the increase side in order to adjust the assist power to be provided to a MAT 26, thus to increase the supercharge assist controlled variable. When the post-correction ignition-timing shows a value on the retard side of the base ignition-timing, the MAT power restriction coefficient K is corrected (learned) on the decrease side, thus to decrease the supercharge assist controlled variable.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a sudden change in torque when supercharging pressure is not proper just after switching to two-cycle operation from four-cycle operation.
SOLUTION: When an operation state of an engine 10 changes between an area for performing premix spark ignition four-cycle operation and an area for performing premix compressed self-ignition two-cycle operation, operation of the engine 10 is properly performed after switching an operation cycle by properly controlling actual supercharging pressure Pr before switching the operation cycle. When air quantity sucked in a cylinder 142 is kept substantially constant by adjusting the valve timing of intake-exhaust valves 132 and 134 according to a change in the supercharging pressure Pr, a fluctuation in the torque is further reduced.
