摘要： The present invention relates to the atomization and vaporization of spray at the time of cold startup and the reduction of the amount of fuel depositing on the inner wall of the intake manifold, thereby ensuring improved startability of an internal combustion engine of a car, reduced fuel costs and improved purification of exhaust gas. A very fine groove (201) is formed on a heat transfer surface (76) in a fuel vaporization promoting apparatus (100), wherein this groove (201) is shaped in such a way that fuel (24) is dispersed by the surface tension of a heat transfer surface (76) and fuel (24). This configuration ensures uniform dispersion of fuel (24) on the heat transfer surface (76) and effective promotion of vaporization

摘要： The target peak current value where current value is reduced in conformity to the drop of voltage of battery (18) is stored in target peak current storage unit (68). ON-signals are sent from current control circuit (56) to power transistor (50) in response to the injection command pulse coming from engine controller (58) so that current is applied to coil (20). Then the current flowing to coil (20) is detected by the current detecting resistor (52). Comparator (62) compares this detected current and the target peak current value read from the target peak current storage unit (68) conforming to the voltage of battery (18). If agreement is found between these two values, OFF-signals are sent to power transistor (50) from current control circuit (56) in response to the switching command coming from comparator (62). Then the On/Off signals to send holding current to coil (20) are sent from current control circuit (56) to power transistor (50). The linearity of the injection volume despite changes in battery voltage can be maintained.

摘要： The invention relates to a method for high volume and high pressure operation of a variable delivery type single cylinder plunger pump, the displacement of the piezoelectric element (20) is magnified by a hydraulic displacement magnifying mechanism comprising a large-diameter bellows (204), a small diameter bellows (202) and working fluid (208), and an engaging member (201) is displaced to control the time interval of opening and closing the intake valve (5). The large-diameter bellows (204) is used at all times in the state compressed in the direction of displacement transfer, thereby ensuring that the pressure of the working fluid (208) is maintained at a positive value to prevent vapor from being generated. The thermal expansion of a casing (23) is selected in such a way that the total thermal expansion of the piezoelectric element (200) and hydraulic displacement magnifying mechanism in the direction of displacement transfer is approximately the same as the thermal expansion of the casing (23), whereby highly efficient driving is provided.

摘要： A fuel-injection valve (100) includes a fuel-injection hole (2), a valve element (4) and a valve seat (3) for opening and closing the fuel-injection hole, a force-applying member (12) for applying force to the valve element in a direction of motion of the valve element, and a drive unit (5, 10, 14, 15) for applying force to the valve element (4) in the direction opposite to that of the force applied by the force-applying member; wherein a secondary oscillation system (13, 17), which interacts with a primary oscillation system (14, 12) including the valve element (4) and the force-applying member (12), is added to the primary oscillation system, and the phase angle of force applied to the primary oscillation system by the secondary oscillation system is also staggered from that of force applied to the primary oscillation system, which is other than the force applied to the primary oscillation system by the secondary oscillation system,; whereby the bouncing of the valve element during opening and closing of the valve is reduced, which in turn makes it possible to achieve very accurate fuel-injection control.
