摘要： A control device for controlling an engine includes main-chamber injecting means (1,3) that supplies a main chamber (8) with fuel; sub-chamber injecting means (2) that supplies a sub chamber (5) with fuel after the main chamber injecting means (1,3) supplies the fuel; estimating means (21) that estimates a degree of knocking serving as indices of an intensity of the knocking and an occurrence frequency of the knocking; and fuel controlling means (22) that carries out, when the degree (N) of the knocking is a first predetermined value (N1) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (2). By reducing the sub-chamber fuel amount in this manner, the occurrence of knocking can be suppressed, so that the combustion state of a divided-combustion-chamber engine can be enhanced.

摘要： A control device for a hybrid vehicle determines whether an EGR valve has an opening failure, and performs a pre-operation in which the engine is operated at a load smaller than a load in a series mode for a certain period of time while the vehicle is driven by a motor immediately before switching from an EV mode to the series mode. The pre-operation has a normal pre-mode in which the engine is operated at a first load when it is determined that the EGR valve does not have an opening failure, and a small failure pre-mode and a large failure pre-mode in which the engine is operated at a second load larger than the first load when it is determined that the EGR valve has the opening failure.

摘要： A control unit diagnoses a failure of a fuel storage unit that seals a fuel tank and a processing unit that processes fuel evaporative gas in the fuel tank. A first pressure detection unit of the fuel storage unit detects the pressure of the fuel tank. A second pressure detection unit of the fuel storage unit is disposed at a position different from the first pressure detection unit, and detects the pressure of the fuel tank. The control unit specifies a failure portion of the fuel storage unit and the processing unit based on a change in either one or both of a first pressure value detected by the first pressure detection unit and a second pressure value detected by the second pressure detection unit when the pressure of the fuel tank is changed.

摘要： A control system for a vehicle (1) provided with a differential mechanism (3) that applies a torque difference to left and right wheels (5) and two electric motors (2) coupled to the differential mechanism (3), the control system including: two control units (11, 12) being connected to each other via high-speed communication means and each controlling one of the two electric motors (2); a first rotation speed sensor (26R) that detects a first rotation speed of a first electric motor (2R) of the two electric motors (2) and outputs the first rotation speed to the two control units (11, 12); a second rotation speed sensor (26L) that detects a second rotation speed of a second electric motor (2L) of the two electric motors (2) and outputs the second rotation speed to the two control units (11, 12); and a superordinate control unit (10) that calculates demanded torques of the two electric motors (2) based on vehicle information of the vehicle (1). At least a first control unit of the two control unites (11, 12) calculates two assigned torques to achieve the demanded torques calculated in the superordinate control unit (10) based on detection signals of the two rotation speed sensors (26R, 26L).

摘要： A rear suspension cross member (4) is suspended and supported on a lower side of a floor (2), and a drive unit (8) including a driving motor (9), an inverter (10) and a transaxle (11) is mounted on the rear suspension cross member (4). A power supply unit (20) including a junction box (21), a charger (22) and a DC-AC inverter (23) is mounted on the floor (2), and a terminal block (21a) of the junction box (21) is connected to a terminal block (10a) of the inverter (10) via a motor-side power cable (42). The junction box (21) and the inverter (10) are disposed on opposite sides of each other with respect to a center line (L) in the left-right direction of the vehicle body.

摘要： FIG. 1 is a front view of a first image in a sequence for a vehicle display device screen or portion thereof with animated image according to my new design;
FIG. 2 is a front view of a second image thereof; and,
FIG. 3 is a front view of a third image thereof.
The appearance of the animated image transitions between the images shown in FIGS. 1-3. The process or period in which one image transitions to another forms no part of the claimed design.
The outermost broken lines depict the vehicle display screen or portion thereof in which the design is embodied that form no part of the claimed design. The remaining broken lines illustrate portions of the animated image that form no part of the claimed design.-

摘要： An auxiliary chamber type internal combustion engine includes a main chamber, an auxiliary chamber, a plurality of connecting passages connecting the main chamber with the auxiliary chamber, and an ignition plug configured to ignite a mixture introduced into the auxiliary chamber. The plurality of connecting passages include a first connecting passage having a first injection port and a second connecting passage having a second injection port. A flame generated in the auxiliary chamber is injected into the main chamber through the first and second injection ports. The first injection port is configured such that the flame propagates along a ridge line at which the plurality of inclined surfaces of the cylinder head intersect. The second connecting passage extends in a direction oriented to the piston with respect to the first connecting passage when viewed from a direction perpendicular to the cylinder axial direction.
