  • Patent number: 11028790
    Abstract: In a purge control valve device, a purge valve includes a first electromagnetic valve and a second electromagnetic valve which are provided inside a housing. The first electromagnetic valve has a first valve body that controls a flow rate of evaporative fuel flowing in the housing. The second electromagnetic valve has a second valve body that controls a flow rate of evaporative fuel flowing in the housing. The upstream passage and the downstream passage are arranged in series. The first electromagnetic valve switches a seated state and an unseated state of the first valve body. The purge valve has a narrowed passage in which a flow rate of the evaporative fuel is smaller in one of the seated state and the unseated state than in another of the seated state and the unseated state.

  • Patent number: 11015322
    Abstract: A control device for a hydraulic machine such as a revolving excavator work machine having a structure that can cope with such an engine output decreasing environment as a work under a low atmospheric pressure at a high altitude without generating noise caused by engine rotation number increase. The control device corrects a control output value to be applied to an electromagnetic proportional valve for load-sensing valve control in a load-sensing type pump control system, based on a detected state quantity related to the engine output decreasing environment. When an engine speed-sensitive pump control system is adopted, a control output value generated based on a detected decrease in the actual engine rotation number is combined with a control output value generated by the load-sensing type pump control system.

  • Patent number: 11015537
    Abstract: Power plants using multiple identical engine block assemblies to form multiple engines, each contributing to a common output or outputs, and each using an intake manifold, an exhaust manifold and an air rail. Air is first compressed by some engine cylinders and delivered to the air rail, and then coupled to combustion cylinders from the air rail. Compressions and combustion may be in the same cylinders, the same engine block assembly but different cylinders or in different engine block assemblies. Multiple engines in the power plants are less costly than single large engines because of the quantity of manufacture and ease of maintenance. Various embodiments are disclosed.

  • Patent number: 11008970
    Abstract: A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

  • Patent number: 11002200
    Abstract: An evaporated fuel processing device includes a relationship learning unit that, during a learning operation, learns the relationship between a valve opening start amount and a pressure difference. In particular, the relationship learning unit learns this relationship when a valve opening detection unit detects a plurality of different valve opening start amounts and a pressure difference detection unit detects a plurality of different pressure differences. Then, the relationship learning unit creates a relationship map between the valve opening start amount and the pressure difference. The evaporated fuel processing device then corrects the valve opening start amount based on this relationship map.

  • Patent number: 10989158
    Abstract: A controller for an internal combustion engine includes processing circuitry. The processing circuitry executes a selecting process that selects one of a multi-injection process or a single injection process. The multi-injection process includes executing an intake synchronous injection and an intake asynchronous injection. The single injection process includes executing the intake asynchronous injection. In the intake synchronous injection, the fuel is injected in synchronization with a period in which an intake valve is open. In the intake asynchronous injection, the fuel is injected at timing advanced from timing of executing the intake synchronous injection. The processing circuitry changes ignition timing to a retarded side value in accordance with switching from execution of the multi-injection process to execution of the single injection process.

  • Patent number: 10982619
    Abstract: A controller for vehicle is provided. A determining section obtains fuel pressure in a delivery pipe and performs a rationality check for determining whether the obtained fuel pressure is within a normal range. The determining section shifts the normal range toward a high pressure side when a second index value of a vehicle outside temperature is higher than a first index value as compared with when the second index value is not higher than the first index value. The second index value is obtained when the determining section is activated. The first index value is stored in a nonvolatile memory before a main switch is turned off so that power supply is stopped.

  • Patent number: 10968856
    Abstract: When an incremental amount of a steering angle exceeds a reference incremental amount, an ECU 60 executes vehicle attitude control of reducing an output torque of an engine, and, in a given operating range, drives a spark plug 16 in a manner allowing an air-fuel mixture to be self-ignited at a given timing, thereby executing SPCCI combustion. When there is a request for an additional deceleration from the vehicle attitude control (#12: YES), and the SPCCI combustion is performed (#13: YES), the ECU 60 executes fuel amount reduction control of reducing the amount of fuel to be supplied into a cylinder 2 (#14), so as to attain torque reduction for the vehicle attitude control. On the other hand, when the SPCCI combustion is not performed (#13: NO), the ECU 60 executes ignition retardation control of retarding an ignition timing of the spark plug 16 (#15).
