摘要： PROBLEM TO BE SOLVED: To prevent partial wearing in the journal at a crank end and reduce friction losses and the discharge of an oil pump. SOLUTION: In a crank shaft supporting structure, at least one of the journals at both ends of a crank shaft 3 is supported by roller bearings 15 and the other journals are supported by sliding bearings 17. Concretely, a first journal 1J is provided with the roller bearings 15 and the other journals 2J to 5J are provided with the sliding bearings 17. The fifth journal 5J may also be provided with another roller bearing 15 at the opposite end. The loading direction of a crank end is biased due to a timing belt load, an auxiliary belt load and a flywheel weight. Even under such conditions, partial wearing is prevented by the roller bearings 15. The roller bearings 15 reduce friction losses in a lower rotation area in normal use. In addition, since oil supply is unnecessary or let off a little amount, the discharge of the oil pump can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a cylinder head gasket capable of rigidly connecting a cylinder head with a cylinder block via a protrusion-recess engagement section 21, preventing deformation of the cylinder block due to the explosion pressure in the engine and achieving reduction in sealing capability. SOLUTION: The cylinder head gasket 1 is held in between the cylinder head 2 and the cylinder block 3 having a cylinder bore 4, and is formed by laminating a thickness adjustment plate 10 in which a combustion room hole 14 is bored in the position corresponding to the position of the cylinder bore 4, seal plates 11 to 13 and a shim plate 17. The protrusion-recess engagement sections 21 projecting to both sides of the cylinder head gasket around the combustion room holes are formed over each of the laminated layers including the seal plates, the thickness adjustment plate and the shim plate. The engagement sections integrally connect the laminated layers including the seal plates, the thickness adjustment plate and the shim plate with each other. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device for a cylinder injection type internal combustion engine, capable of suppressing starting failures at restart or the like.
SOLUTION: The valve timing of an intake valve 20 in an engine 1 is made variable, by hydraulically controlling a valve-timing variable mechanism 25. When it is judged that the valve timing variable mechanism 25 does not return to the position of locating the valve timing of intake valve 20 as a most delay angle (reference position) at start of the engine 1, the fuel injection amount during engine start and immediately after finishing the engine start, is corrected to be reduced. Thereby, even if the valve timing variable mechanism 25 does not return to the reference position and an internal EGR amount is excessive by the fuel combustion in such a state as to cause an insufficient oxygen condition, it can be suppressed that an air/fuel ratio becomes excessively rich due to such a situation.

摘要： PROBLEM TO BE SOLVED: To provide a valve characteristic control device for internal combustion engine for suppressing lift characteristic dispersion of an engine valve caused by tappet clearance and thereby enabling an internal EGR control with higher accuracy based on a sub-lift of the valve. SOLUTION: On each of an intake valve side and an exhaust valve side, a cam having a main profile 11a for performing a main lift and a sub profile 11b for performing a sub-lift is used. The sub-profile 11b is realized by a three- dimensional cam, lift amount is made variable according to moving of the sub-profile 11b in the cam shaft direction and exhaust circulation at the inside of an engine combustion chamber is controlled. In this case, buffer part gradient w, y on the sub-profile 11b side of the cam is formed so as to be larger than buffer part gradient x, z on the main profile 11a side.

摘要： PROBLEM TO BE SOLVED: To prevent the enlargement of a device and an engine and the interference of the abutment of a cam follower on a cam surface, and to realize a sufficient gas passing amount. SOLUTION: In a lift pattern by an intake cam, two maximal parts Mx1, Mx2 exist in the changing rate of a lift amount to a turning angle on a valve opening side (the advancing side of a peak P), and a minimal part may not exist in the lift amount. Thereby, a rise part having no trough part is formed during an exhaust stroke. Accordingly, exhaust can be recirculated, and the abutment of a cam follower may not be interfered. Besides, even though the lift amount is small, an exhaust passing amount can be sufficiently secured by the whole rise part. Thus, the intake cam which is a three-dimensional cam is not required to have such a profile that a cam profile is changed at a sharp angle or axially lengthened. Therefore, the enlargement of a device and an internal combustion engine can be prevented.

The gasket 5 is provided with a through-hole 19 formed in a position situated astride a space between the cylinder block and the case, and a seal member 20 situated in the through-hole. A recessed part is formed in the cylinder head and a position overlapped with the through-hole. One end part of the seal member is situated in the recessed part and the other end part is inserted through the through-hole and brought into elastic contact with the cylinder block and the case.

摘要： PROBLEM TO BE SOLVED: To precisely measure the temperatures of temperature measuring parts as many as possible of a piston within a cylinder by designing the arrangement of each coil unit or its drive in temperature measurement by electromagnetic induction. SOLUTION: The timing of carrying a high frequency current from a high frequency oscillator to the transmission coil 11 of each coil unit U is switched according to each RS signal generated in the bottom dead point of a piston P from a rotating angle sensor, whereby the mutual electromagnetic induction interfering effect between mutually adjacent receiving coils 12 can be prevented. Thus, even when each space between the coil units U is narrow, the temperatures of six temperature measuring points of the piston can be precisely measured.
