Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness of a vane in the advance direction to be generated by the inertia due to the rotation of a valve timing changing mechanism itself in a valve timing control device provided with a vane type valve timing changing mechanism. SOLUTION: This control device controls oil pressure of a first and a second oil pressure chambers 30, 31 formed between a housing 16 and a vane 19 so as to change the relative turning phase of the housing 16 and the vane 19. Cross sectional area of oil passages S1a, S1b of the operating oil to be supplied from an OCV 40 to the first oil pressure chamber 30 so as to advance the vane 19 is formed larger than the cross sectional area of oil passages S2a, S2b of the operating oil to be supplied to the second oil pressure chamber 31 so as to make the vane 19 lag.

Abstract: PURPOSE:To provide a recirculated exhaust gas cooler for an internal combustion engine which allows the reduction of vibration and noise. CONSTITUTION:A cooler (EGR cooler) 6 to cool recirculated exhaust gas is built in a cylinder block 1, an exhaust manifold 2 is connected to the EGR cooler 6 via the first EGR pipe 3 and the EGR cooler 13 is connected to an EGR valve 5 via the second EGR pipe 4. Since the EGR cooler 6 has high rigidity, the rigidity of a cylinder block side wall is increased and engine noise is reduced. Since the cylinder block l has smaller vibration than a cylinder head, the vibration of the EGR pipe and the exhaust manifold connected thereto is held down and noise confined in a room is reduced.

Abstract: PURPOSE:To prevent decline in sealing performance caused by shrinkage cavity in forming, in sealing structure of a cylinder head cover and a cylinder head formed by die casting. CONSTITUTION:A gasket 3 is interposed between a cylinder head cover 1 and a cylinder head 2 formed from light metal by die casting and the cylinder head cover 1 is fastened to the cylinder head 2 by a bolt so as to secure sealing performance between them 1, 2. A flange 5 is integrally formed around the circumferencial edge of the cylinder head cover 1. The gasket 3 is continuously formed along the flange 5 of the cylinder head cover 1. In a casting mold for the cylinder head cover 1, its liquid metal pouring port is arranged facing to the flange 5. The wall thickness of the gasket 3 is set different partially so that sealing pressure of the liquid metal pouring part 16 of the flange 5 which faces to the liquid metal pouring port becomes higher than sealing pressure of other parts of the flange 5.
