摘要： An extrusion die for forming a honeycomb stucture has a lattice molding groove formed in the outlet surface of the die body. In the inlet surface of the die body there are formed plural independent supply passages that are opposite to the intersecting portions of the molding groove and extend toward the outlet surface. A through hole is designed to communicate adjacent supply passages at a place that forms part of the partition wall between the supply passages and contacts with the molding groove. This through hole takes the combined shape of a trapezoid with the width of the molding groove as its top side and with the diameter of the supply passage as its maximum base side and a semicircle having said base side as its diameter.

摘要： The EGR controller 1 controls the EGR actions wherein exhaust gas from the cylinder cut-off engine 3 which can change over the running condition between the all-cylinder run and the cut-off-cylinder is recirculated to the induction. The EGR controller 1 comprises an EGR control valve 6 for opening and closing the EGR pipe 13, a water temperature sensor 5 for detecting cooling water temperature TW and an ECU 2, and the ECU 2 controls the EGR actions so as tobe executed if the cooling water temperature TW is higher (determined as “Yes” at Step 10) than the upper limit value TWE1H while at the all-cylinder run (determined as “No” at Step 2) or if the cooling water temperature TW is higher than the lower limit value TWE1L while at the cut-off-cylinder run (determined as “Yes” at Step 2).

摘要： In an apparatus for controlling a multi-cylinder internal combustion engine with partial cylinder switch-off mechanism which is switchable between an all-cylinder operation mode in which all cylinders are operated and a partial-cylinder operation mode in which operation of partial cylinders is suspended, the operation of intake valves and exhaust valves is suspended or resumed in a predetermined order with respect to all of the suspended cylinders irrespective of a rotational frequency of the engine. There are provided a solenoid valve on an intake side and a solenoid valve on an exhaust side for switching input hydraulic pressures for hydraulically operated switching devices respectively on the intake side and on the exhaust side between the driving state and the drive-free state. At the time of switching the operation, one of the solenoid valves on the intake side and the exhaust side is driven in advance. The subsequent number of rotations of a crankshaft is counted. When the number of this counting has reached a predetermined value, the solenoid valve on the other side is driven.
