Abstract: A combustion state parameter calculation method for an internal combustion engine, which is capable of continuously calculating a combustion state parameter while properly maintaining the accuracy of the calculated parameter even when part of in-cylinder pressure sensors is in failure. In the combustion state parameter calculation method, as a combustion state parameter, a first combustion state parameter dependent on the magnitude of in-cylinder pressure is calculated based on a detection value from an in-cylinder pressure sensor, on a cylinder-by-cylinder basis. When it is determined that a characteristic abnormality failure in which the magnitude of the detection value deviates from the actual in-cylinder pressure has occurred in part of the in-cylinder pressure sensors and has not occurred in the other in-cylinder pressure sensors, the first combustion state parameter of a failure-determined cylinder is calculated based on the detection value from the other in-cylinder pressure sensors.

Abstract: The present invention relates to a casting die device and a casting method used to obtain a cast product in which an inner bore, at least one end of which is open, is formed. The casting die device has a core pin for forming the inner bore in the cast product, and a vibration-transmitting member for transmitting vibrations from a vibrator of a micro-vibration machine to the core pin. When casting is being performed, vibrations from the vibrator are imparted to the core pin by way of the vibration-transmitting member. The vibrations also propagate to sites surrounding the core pin, in molten metal that has been poured into a cavity.

The guide section has: a first lower guide facing the filter insertion opening and tilted upward; and a second lower guide formed downstream of the first lower guide in the insertion direction and tilted downward. When inserting the filter from the filter insertion opening, the filter is guided along the first lower guide and therefore is inserted while being tilted such that the end of the filter, which is located downstream in the insertion direction, is lifted up. Consequently, the filter can be inserted without contact with the vehicle body-side structure.
