摘要： A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed in the top surface of a piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relatively small thickness. When the fuel injected in nearly the shape of a fan from the fuel injection valve is considered by being divided into a plurality of fuel segments in a radial direction, a side wall of the cavity has a first fuel deflection passage 82a and a second fuel deflection passage 82b for so deflecting at least two of the plurality of fuel segments as to pass near the spark plug. The side wall of the cavity is at least partly provided with a return portion 83 that protrudes toward the inside of the cavity. The first fuel deflection passage is not provided with the return portion 83 or is provided with the return portion having a short protrusion, and the second fuel deflection passage is provided with the return portion 83 having a long protrusion.

摘要： A direct-fuel-injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed on the top surface of the piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relative small thickness. In the engine, the side wall of the cavity facing the fuel injection valve, for leading the fuel to the vicinity of the spark plug, has a horizontal sectional shape consisting of a part of an ellipse shape of which two foci are at a position of the injection hole of the fuel injection valve and a position near to the spark plug in plan view, and the side wall has a deflecting portion to deflect the fuel toward the inside of the cavity.

摘要： An internal combustion engine (10) is provided with a port injector (28) and an in-cylinder injector (22). Before a port injection is started, the total amount of fuel to be injected is calculated (at an injection amount calculation timing). The port injection fuel amount and the in-cylinder injection fuel amount are calculated by appropriately dividing the total amount between them. If a change of the operating load on the internal combustion engine (10) is detected after the injection amount calculation timing, the load change is reflected in the amount of fuel to be injected in the current engine cycle by increasing or decreasing the in-cylinder injection fuel amount.

摘要： A uniaxial eccentric screw pump enabling a stator to be easily separated into an outer cylinder and a lining member, and being capable of solving problems such as a positional shift and deformation of the lining member, and an occurrence of uneven wear and an unstable discharge amount associated with the positional shift and deformation. The stator includes a liner portion having a cylindrical shape and being integrally formed so as to have an inner peripheral surface of an internal thread type and an outer cylinder portion. The liner portion includes, at both end portions thereof, flange portions protruding radially outward, and an outer cylinder mounting portion is provided between the flange portions. The outer cylinder portion is mounted in a non-bonded state on the outer cylinder mounting portion, and both end portions of the outer cylinder portion abut on the flange portions, respectively.

摘要： In an internal combustion engine, it is first determined whether a load factor of the internal combustion engine is a specified value or more and the engine speed of the internal combustion engine is a specified speed or less. If these conditions are satisfied, fuel is injected from both of a port injection valve and a direct injection valve, and a fuel injection timing of the direct injection valve is decided so as to inject fuel from the direct injection valve during the compression stroke of the internal combustion engine.
