摘要： A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator, configured to axially reciprocate, and configured to alternately repeat suction of the fuel and ejection of the fuel more boosted than the fuel at a time of suction by reciprocation of the boosting piston; and a controller to control driving of the linear actuator. When reciprocation amplitude of the boosting piston is A (A>0) and a reciprocating cycle time is T, the controller controls the linear actuator so a maximum value of an absolute value of acceleration when the reciprocating pump sucks the fuel with an absolute value of speed of the boosting piston increasing is smaller than A·(2π/T)2, and so a maximum value of the absolute value of the acceleration of the boosting piston when the reciprocating pump ejects the fuel is larger than A·(2π/T)2.

摘要： A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator and configured to reciprocate in an axial direction, the reciprocating pump being configured to suck the fuel when the boosting piston moves in a first direction and configured to boost and eject the fuel when the boosting piston moves in a second direction; and a controller configured to control driving of the linear actuator so as to adjust an amount of the fuel ejected from a boosting cylinder per reciprocating time by adjusting a ratio of a fuel ejection time and a fuel suction time of the reciprocating pump without changing the reciprocating time of the boosting piston in accordance with a load of the internal combustion engine. The adjustment adjusts a stroke length of the boosting piston and a moving speed of the boosting piston in the second direction.

摘要： A device detects the cam top position in an in-line type high pressure pump with a decreased amount of time required to detect the rotation position of the cam top position in an engine starting operation, thereby decreasing the time for starting an engine. A cam for driving a plunger has a plurality of cam lobes, and a plurality of cam top position pointers are attached to the outer periphery of the camshaft or to the outer periphery of a flywheel connected to the camshaft such that each of the pointers corresponds to each of the cam lobes of the cam in number and angle phase, respectively. A cam top position detector is located to face the pointers when the camshaft rotates so that the pointers are detected by the detector.

摘要： A dual-fuel internal combustion engine with a device for regulating the internal combustion engine, with at least two piston-cylinders, a fuel injector assigned to the piston-cylinder units for a liquid fuel, which has an injector needle. Each piston-cylinder unit has a gas supply device for fuel, wherein the regulating device controls the fuel injector and the at least one gas supply device individually for metering of the quantity of the liquid or gaseous fuel supplied to each piston-cylinder unit. At least one needle sensor is connected to the regulating device and assigned to the respective piston-cylinder unit, which detects a characteristic signal of the needle position in the ballistic range, so that the fuel injector can be operated with individual controllability for each of the at least two piston-cylinder units for the regulation of the supplied fuel quantity in the ballistic range.

摘要： A fuel injector for an internal combustion engine includes an injector body in which there are positioned an actuator, a control valve, and a needle guide. The actuator actuates the control valve, the control valve controlling an injection needle sliding the needle guide between an open position in which injection is permitted and a closed position in which the injection of fuel is prevented. The injector additionally includes a first electrical connection extending from the needle guide to a metal that are internal to the injector, and a metal extension extending from the metal ring to a connector pin accessible from the outside of the injector, so that an electrical signal indicative of the position of the needle can be transmitted from the needle guide for the needle to the connector pin.

摘要： A method for determining a position of a lock element of an injection valve for an internal combustion engine includes moving the lock element in the direction of a locked position in a closing movement in order to lock the injection valve, subsequently measuring a closure time at which the lock element arrives in the locked position, determining a time difference between the closure time and a preceding starting time of the closing movement, and determining, based on the time difference, a position which the lock element has assumed at the starting time of the closing movement.
