摘要： The application is directed to a diesel engine. If the rack cannot complete a predetermined operation within a predetermined amount of time due to the key switch being held at a start-position, the control unit controls a starter to cause a plunger to perform a preparatory stroke operation, and the stroke operation by the plunger is stopped before the diesel engine starts.

摘要： An engine control device is provided with a main operation unit, an auxiliary operation unit, a changeover switch, and an engine control unit. The main operation unit is capable of performing an operation of changing a rotation speed of a propulsion engine mounted on a ship. The auxiliary operation unit is capable of performing an operation of changing the rotation speed of the engine instead of the main operation unit. The changeover switch is capable of performing an operation of switching between a main ship handling state in which the rotation speed of the engine can be changed by operating the main operation unit and an auxiliary ship handling state in which the rotation speed of the engine can be changed by operating the auxiliary operation unit. The engine control unit stops the engine when the changeover operation unit is operated to switch from the auxiliary ship handling state to the main ship handling state.

摘要： In cases where a control device determines that a load is continuously less than a predetermined value for a predetermined period, the control device executes a first control to maintain the engine speed at a first rotation speed or higher, and when the control device determines that the load reached the predetermined value within the predetermined time, the control device executes a second control to maintain the engine speed at a second rotation speed or higher, which is higher than the first rotation speed. This provides a control device for an engine and an engine, which can restrain activation of an oil pressure switch attributed to an oil temperature.

摘要： An engine device, which employs various types of fuels, plural fuel pipes can compactly be disposed without being thermally affected by exhaust gas. In the engine device, a gas fuel pipe that supplies gas fuel to a gas injector, a fuel oil pipe that supplies liquid fuel to a main fuel injection valve are disposed to be divided on both sides of a row of head covers arranged in a line. In addition, in the engine device, an intake manifold that supplies air taken in by a main combustion chamber toward an intake valve extends in parallel to the row of head covers in a cylinder block, and the fuel gas pipe and the intake manifold are arranged on the same side of the row of head covers.

摘要： Provided is an engine with a starter valve arranged in a compact space and with a cylinder head having a cooling water passage and a starter valve feeding compressed air to a combustion chamber. The starter valve is arranged parallel in the axial direction to a cylinder while fitted into a sleeve, and a portion of the cooling water passage is formed by the outer surface of the sleeve fitted into a starter valve insertion hole formed in the cylinder head. A starting air passage orthogonal to the axial direction of the starter valve insertion hole is formed in the cylinder head, and a portion of the wall surface of the starting air passage is formed by the end surface on one side of the sleeve.
