Abstract: A central processing unit (CPU) 20 of a micro controller unit (MCU) 10 (information processing apparatus) sequentially executes a first-partial program (Block J) and a second-partial program (Block K). The first-partial program causes the CPU 20 to perform redundancy execution of the first unique process associated with the first-partial program twice or more (Steps S202-S208 and S212-S218). Then, the first-partial program causes the CPU 20 to record each piece of output data output for each of first unique processes (unique processes J_0 and J_1) in each of the first data regions (data regions D0j and D1j) pre-allocated to each piece of output data, and permit execution of the second-partial program subsequently to the first-partial program (Step S238) when pieces of output data of the first unique process or digest values of the output data recorded in first data regions match (Steps S220 and S228).

Abstract: A water jacket includes: a cooling channel through which a coolant flows, the cooling channel being formed in a cylinder block in which a plurality of cylinders are formed such that the cooling channel is positioned outside the cylinders; and a cooling groove (slit) through which the coolant flows, the cooling groove being formed between adjacent ones of the cylinders. When a slit end portion is viewed in sectional view in a direction in which the cylinders are arranged, the slit end portion and a cylinder-block inner wall are continuous with each other via an inclined portion inclined so as to become thicker toward the cylinder-block inner wall.

Abstract: Secondary vibration generated accompanying reciprocation of a piston (21) of a multi-link variable compression ratio engine (E) can be eliminated effectively, even when the direction of the secondary vibration is inclined relative to a cylinder axis (L1), by inclining the direction (shown by arrow) of an excitation force generated by a secondary balancer system (43) so that it coincides with the direction of the secondary vibration. The secondary balancer system (43) is formed by supporting balancer weights (44a, 45a) on a pair of balancer shafts (44, 45) rotating in directions opposite to each other, and by displacing the phases of these balancer weights (44a, 45a) the direction of the excitation force generated can be inclined so as to coincide with the direction of secondary vibration of the engine (E).

Abstract: A variable stroke characteristic engine in which a piston (11) and a crankshaft (30) are linked to a control shaft (65) via a variable stroke link mechanism (LV), and the variable stroke link mechanism (LV) is operated by a hydraulic actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, in which the hydraulic actuator (AC) is formed from a housing (HU), a cover member covering an aperture of the housing (HU), a vane case provided integrally within the housing (HU), and a vane shaft (66) housed within the vane case, and the vane shaft (66) is formed integrally with the control shaft (65). The number of components of the actuator (AC) can be decreased, and its ease of assembly can be improved.

Abstract: A stroke characteristic variable engine comprising a primary link connected to a piston which is slidably fitted in a cylinder, a secondary link connecting the primary link with a crankshaft and a tertiary link connected to the primary link or the secondary link at one end and to an engine main body via a control shaft at the other end thereof. An oil level position of engine oil stored in an oil pan is set such that at least part of the control shaft is submerged in the engine oil, whereby since oil stored within the oil pan can be used as it is, the lubrication around the control shaft can be ensured in a simplified configuration.

Abstract: In a variable stroke-characteristic engine for a vehicle, a control shaft and a control link are disposed on a front side of a vehicle body with respect to a crankshaft. An actuator for driving the control shaft is disposed on an outer surface of an engine block on the front side of the vehicle body. Thus, the actuator projects as much as possible from a position of the engine block toward the front side of the vehicle body so that traveling wind from ahead of the vehicle is effectively applied to the actuator to enhance the cooling effect. Hence, any temperature increase of the actuator is suppressed. Moreover, the actuator is disposed as far as possible from an exhaust manifold that is heated to a high temperature by the heat of an exhaust gas.

Abstract: A main journal 25a of a crank-shaped swinging shaft 25 which swings in a range of a predetermined angle is supported by bearing metals 51 and 52 each divided into two pieces. In supplying a lubrication oil through an oil bore 51b in the bearing metal 51 to a sliding surface of the main journal 25a and to inlet openings of lubrication oil passages P1 and P2 of the swinging shaft 25 open to the sliding surface, the inlet openings of the lubrication oil passages P1 and P2 of the swinging shaft 25 are designed so that they do not move past division portions 55 of the bearing metals 51 and 52 upon swing of the swinging shaft 25 in the range of the predetermined angle. Therefore, it is possible to prevent the lubrication oil to be supplied to the lubrication oil passages P1 and P2 from leaking from the division portions 55 of the bearing metals 51 and 52, thereby reliably lubricating a pin journal 25b of the swinging shaft 25 by the lubrication oil supplied from the lubrication oil passages P1 and P2.
