    Abstract: An internal combustion engine system includes an internal combustion engine including a cylinder, an intake valve and an exhaust valve, a cylinder injection valve, and a variable valve drive mechanism, and a control device that controls the cylinder injection valve and the variable valve drive mechanism. The control device includes a calculation unit that calculates a first crank angle section where a temperature of the cylinder is equal to or higher than a boiling point of the fuel in a compression stroke before completion of warming-up of the internal combustion engine and a second crank angle section where the temperature of the cylinder is equal to or higher than the boiling point of the fuel in the valve closed period, and an injection controller that executes fuel injection in the first and second crank angle sections by the cylinder injection valve.

    Abstract: A control device for driving/controlling an engine on the basis of a signal from a temperature state detector, a rotation detector, and a rotational speed setting device is provided. The control device includes a start temperature determining processing unit configured to determine whether or not a temperature (T) at start of the engine is less than a predetermined temperature (Tw1) and a start control processing is performed in accordance with a set value of a target rotational speed (Nset) by the rotational speed setting device in case the start temperature (T) is equal to or less than the predetermined temperature (Tw1).

    Abstract: Method for reducing emission of pollutants from an internal combustion engine including at least one combustion chamber. A fuel emulsion is injected into a combustion chamber; the fuel emulsion is ignited in the combustion chamber in the presence of air; and the internal combustion engine is operated so as to reduce peak combustion temperature in the combustion chamber. The fuel emulsion has a liquid hydrocarbon fuel, water, at least one emulsifier and at least one oxygen-containing water soluble organic compound. A considerable reduction of particulate emissions is obtained by using this fuel emulsion while maintaining or even further reducing the NOx level which is already reduced by the engine itself.

    Abstract: Start of fuel delivery for a fuel-injected engine having separate unit injectors is adjusted by effecting a positional adjustment of camshaft lobes on a camshaft. The camshaft is used to operate the unit injectors, as well as control exhaust valve operations. By separately controlling the position of the cam lobes which operate the unit fuel injectors, a change it start of fuel delivery is effected. A change in relative position of the cam lobes is accomplished by shifting a guide rod within a hollow body of the camshaft. The change in position of the guide rod, in turn, effects a change in position of the cam lobes which are connected to the guide rod.

    Abstract: In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses. To obtain independent control over injection pressure and timing, a fuel injector in which a hydraulic link is formed between plungers of a multi-plunger arrangement is used with the timing arrangement in order to allow the injection pressure to be maintained constant over a wide range of engine speeds without interfering with engine timing.

    Abstract: Fuel injection apparatuses are used to inject fuel into the combustion chambers of compression ignition engines. The known mechanical drive arrangements for driving the distributor rotor and controlling beginning moment of fuel injection are complex, bulky and expensive to manufacture. The subject timing control for fuel injection apparatus includes a planetary gear arrangement driven by a pumping section and drivingly connected to a distributor rotor. A ring gear controls the timing phase relationship between the rotor and a delivery passage communicating the pumping section with the rotor. A riser of a flyweight assembly is mechanically connected to the ring gear so that the ring gear is positioned in accordance with the engine speed. The planetary gear arrangement is of simple construction requiring a minimum of space and is relatively inexpensive to manufacture.

    Abstract: An injection timing control device for an internal combustion engine includes a connector plate constantly biased in a predetermined direction. A hydraulic actuator urges the connector plate in the other direction in response to a fluid pressure communicated thereto, thereby actuating an eccentric cam mechanism to vary a fuel injection timing. The line of action of the biasing force and that of the urging force opposite to the biasing force, each imparted to the connector plate, lie in a common plane which contains an axis of the hydraulic actuator, so that the connector plate is prevented from tilting and thereby effecting the operation of the cam mechanism.
