    摘要： There is disclosed a method of operating an engine assembly including a combustion engine and a common-rail injector. The method includes: injecting fuel into a combustion chamber of the combustion engine via the common-rail injector thereby generating a backflow of fuel; and powering an actuator using at least a portion of the backflow of fuel. An engine assembly including the combustion engine is disclosed; the engine assembly having a fuel circuit fluidly connecting a fuel source, the common-rail injector, and the second injector outlet together. The fuel circuit has an actuator sub-circuit operatively connected to an outlet of the common-rail injector and an actuator fluidly connected to the actuator sub-circuit.

    摘要： A method for controlling an internal combustion engine having a plurality of cylinders including a first cylinder and one or more remaining cylinders includes selecting a desired auto-ignition dwell for a first combustion cycle for the first cylinder of the plurality of cylinders. A first fuel mass is provided to the first cylinder which is combusted during the first combustion cycle. An actual auto-ignition dwell for the first combustion cycle which results from the first fuel mass is determined and a dwell error is calculated. The dwell error is used to determine a second fuel mass which provided to the first cylinder and which is combusted during the second combustion cycle.

    摘要： A vehicle control device is a vehicle control device for a vehicle capable of coasting, in which when there is no acceleration or deceleration request to the vehicle while traveling, power transmission between an engine and drive wheels is cut off and the vehicle is allowed to travel by inertia, wherein in a state in which there is no acceleration or deceleration request to the vehicle while traveling and power is transmitted between the engine and the drive wheels, whether or not to implement the coasting is determined by comparing a required deceleration rate Dt which is estimated as a deceleration rate to be later required of the vehicle and a coasting deceleration rate Dn which is estimated as a deceleration rate during the coasting. Where it is determined to implement the coasting, power transmission between the engine and the drive wheels is cut off and the coasting is implemented, and where it is determined not to implement the coasting, power transmission between the engine and the drive wheels is maintained. As a result, the implementation of coasting that can provide a sense of anxiety or discomfort to the driver can be suppressed.

    摘要： An engine-powered work tool includes an engine having a crank shaft, an output controller and a wind governor. The output controller includes an output control shaft angularly rotatable about its axis for controlling a rotation speed of the crank shaft. The wind governor can control the angular rotation of the output control shaft and includes: a governor plate for receiving cooling air generated at a cooling fan connected to the crank shaft; an arm fixed to the output control shaft; and a governor spring connected to the arm for biasing the output control shaft to increase the rotation speed of the crank shaft. The governor plate functions to bias the output control shaft to decrease the rotation speed of the crank shaft upon receipt of the cooling air. The governor spring has an end changeable in position relative to the output controller among a plurality of prescribed positions.

    摘要： A fuel injection control apparatus of an internal combustion engine, which can appropriately control the amount of fuel injection from an in-cylinder injection valve so as to achieve a desired air-fuel ratio, regardless of the operating state of the internal combustion engine, is provided. The fuel injection control apparatus comprises: an additional injection means which, when determining that the operating state of the internal combustion engine is a transient state, allows the in-cylinder injection valve to inject a fuel amount conformed to a changing intake air amount; and a subtraction means for subtracting a minimum fuel amount, injectable from the in-cylinder injection valve, from a fuel amount to be injected, before injection by the additional injection means is performed.

    摘要： An internal combustion engine includes a first injector and a second injector for injecting fuel directly into a combustion chamber in a cylinder in a crank case of the internal combustion engine. The combustion chamber is delimited at one side by a piston which is arranged in the cylinder so as to carry out a stroke and at the other side by a cylinder head. At least one gas exchange inlet valve and a gas exchange outlet valve are provided in the cylinder head for a charge exchange. The first injector is largely oriented in the direction of a cylinder axis, and the second injector is oriented at an angle to the cylinder axis. Maximally 80% of a full-load fuel quantity required by the internal combustion engine for a full load can be introduced into the cylinder using the first injector and maximally 50% using the second injector. The injectors can be configured for smaller fuel flow rates using the internal combustion engine design and operating method, whereby the precision of the injection is improved.
