  • Patent number: 10267239
    Abstract: It is an object to suppress turbo lag, while suppressing a decrease in torque in an acceleration-transient state to a supercharged state, occurring owing to a rise in required load. In a prescribed steady state, an engine compression ratio ?m and ignition timing Tm are set so as to achieve a maximum thermal efficiency. In contrast, in a transient state from a non-supercharged state to a supercharged state, occurring owing to a rise in required load, the engine compression ratio is corrected to a higher compression ratio ?h and concurrently the ignition timing is corrected to a retarded timing value Th, in comparison with the engine compression ratio ?m and the ignition timing Tm during steady-state operation for the same load, thereby increasing exhaust energy due to a reduction in cooling loss and consequently suppressing a delay of response to a rise in supercharging pressure.

  • Patent number: 10267206
    Abstract: In inline four cylinder internal combustion engine (1), exhaust ports for a #2 cylinder and a #3 cylinder merge inside cylinder head (3) and form an opening serving as a single collective exhaust port. Exhaust manifold (5) has individual exhaust pipes (6, 7) for #1 and #4 cylinders and collective exhaust pipe (8), and the leading ends of these three exhaust pipes (6, 7, 8) are connected to catalytic converter (11). Exhaust gas introduction angle (?2) of each of individual exhaust pipes (6, 7) is larger by 30-60 degrees than exhaust gas introduction angle (?1) of collective exhaust pipe (8). Consequently, flow velocity distribution and temperature distribution in a catalyst carrier become uniform.

  • Patent number: 10267418
    Abstract: The present invention relates to a control device and a control method for a vehicle in which a lockup clutch is disengaged when a rotation speed of an engine falls below a disengagement rotation speed. The device/method changes a speed ratio of a variator on the basis of a shifting map in which a primary pulley rotation speed on a coast line is set higher than a primary pulley rotation speed on a drive line and sets a target input rotation speed of the variator to a predetermined target input rotation speed higher than the primary pulley rotation speed on the drive line when an operation of an accelerator pedal is performed such that an accelerator pedal opening falls to a first predetermined opening or less. As a result, the present invention can suppress drop of fuel efficiency of the engine caused by disengagement of the lockup clutch which is a friction engagement element.

  • Patent number: 10267352
    Abstract: A bearing cap (1) is attached to a bulkhead (22) of a cylinder block (21) made of a light metal through a pair of bolts (24). The bearing cap (1) has a frame (2) made of an iron-based metal and a cast light-alloy part (3). The frame (2) has a pair of pillar parts (9) through which the bolts (24) extend and a circular-arc-shaped arch section (10). At high temperatures, the span of the pair of the bolts (24) increases due to thermal expansion of the light-alloy material, and the pair of the pillar parts (9) expand. This causes the middle part of the arch section (10) to shift upward, thereby suppressing an increase in bearing clearance.
