20140151468 | FUEL INJECTION VALVE - Fuel injection valve with conical valve seat surface that abuts a valve body to seal fuel, fuel injection orifices having an inlet opening formed on the valve seat surface, wherein fuel sprays injected from the plurality of fuel injection orifices include a first fuel spray constituted by a fuel spray injected from at least one fuel injection orifice and a second fuel spray constituted by a plurality of fuel sprays injected at an outer periphery of the first fuel spray, and a fuel injection orifice that injects the first fuel spray constituted with a plane that includes an orifice axis connecting a center of an inlet with a center of an outlet of the fuel injection orifice, parallel to a center axis of the fuel injection valve intersecting a plane, a conical apex that forms the valve seat surface to form an inclination angle that is larger than 0°. | 06-05-2014 |
20150047611 | SPARK-IGNITION DIRECT FUEL INJECTION VALVE - A spark-ignition direct fuel injection valve includes, at least, a seat member provided with a fuel injection hole and a valve seat and a valve body which controls fuel injection from the injection hole by contacting and separating from the valve seat. In the spark-ignition direct fuel injection valve: the injection hole has an injection hole inlet which is open inwardly of the seat member and an injection hole outlet which is open outwardly of the seat member; an opening edge of the injection hole inlet has a first round-chamfered portion formed on an upstream side with respect to a fuel flow toward the injection hole inlet; and an extending length (L) of the injection hole does not exceed three times a hole diameter (D) of the injection hole. | 02-19-2015 |
20150233334 | Fuel Injection Valve - An object of the present, invention is to suppress the decrease in seal performance by avoiding wide-area contact between a valve face and a valve seat face which contact results from the non-circularity of the valve face and the valve seat face. In a fuel injection valve which includes: a seat member ( | 08-20-2015 |
20150267665 | Electromagnetic Fuel Injection Valve - Provided is an electromagnetic fuel injection valve in which in both operations of opening and closing a valve, a movable element is made to free run before a valve element starts to operate, and bounding motion of the movable element occurring at the time of the valve opening operation is reduced, thereby balancing improvement of responsiveness and improvement of stability of operation. There are equipped with: a first movable element | 09-24-2015 |
20150337782 | FUEL INJECTION VALVE - Fuel injection valve with conical valve seat surface that abuts a valve body to seal fuel, fuel injection orifices having an inlet opening formed on the valve seat surface, wherein fuel sprays injected from the plurality of fuel injection orifices include a first fuel spray constituted by a fuel spray injected from at least one fuel injection orifice and a second fuel spray constituted by a plurality of fuel sprays injected at an outer periphery of the first fuel spray, and a fuel injection orifice that injects the first fuel spray constituted with a plane that includes an orifice axis connecting a center of an inlet with a center of an outlet of the fuel injection orifice, parallel to a center axis of the fuel injection valve intersecting a plane, a conical apex that forms the valve seat surface to form an inclination angle that is larger than 0°. | 11-26-2015 |
20150354515 | Fuel Injection Device - A fuel injection valve having a variable stroke mechanism is constructed. A valve body provided to be slidable; a first movable element for cooperating with the valve body; an inner fixed iron core provided at a position to oppose a second movable element; an outer fixed iron core; and a coil are included. A lift amount of the second movable element is set larger than a lift amount of the first movable element, and a portion of the second movable element is projected into the first movable element. In this way, large and small lifts are constituted by using a difference between magnetic attractive forces that are generated in the first movable element and the second movable element by a current supplied to the coil. | 12-10-2015 |
20150361938 | Fuel Injection Valve - An object of the invention is to provide a fuel injection valve that applies a swirl to an upstream side of a seat section to shorten spray penetration. | 12-17-2015 |
20150377176 | Drive Device for Fuel Injection Device - An object of this disclosure is to provide a fuel injection device that can reliably detect an operation timing of a valve body, that is, a valve opening timing with high accuracy. The current of an electromagnetic valve reaches I | 12-31-2015 |
20150377200 | Fuel Injection Valve - In a fuel injection valve, it is possible to obtain spray in which the penetrating force of injected fuel is suppressed. | 12-31-2015 |
20150377202 | Fuel Injection Valve - In a fuel injection valve used in an internal combustion engine, fuel spray travel distance is shortened. | 12-31-2015 |
