PROBLEM TO BE SOLVED: To accurately carry out metering of reagent by reagent metering supplying which adopts a volume-type metering pump and to finely spray at high pressure. SOLUTION: For improving an NO x ratio in exhaust gas flow to a predetermined ratio, the method for metering and supplying the reagent to the exhaust gas flow of an internal combustion engine 3 uses a reagent injector 40 and injects the reagent from a reagent tank 20 to the exhaust gas flow at an upstream position of SCR catalyst, according to a first metering supplying schedule related to a first range of engine operating conditions. For allowing heat transfer between the reagent injector 40 and the injected reagent, the method uses the reagent injector 40 and injects the reagent from the reagent tank 20 to the exhaust gas flow at the upstream position of the SCR catalyst, according to a second metering supplying schedule related to a second range of the engine operating conditions. Metering supplying is carried out according to the first or second metering supplying schedule depending whether the engine operating conditions are within the first range or within the second range. The NO x ratio in the exhaust gas flow improved by metering supplying by using the second metering supplying schedule is lower than the predetermined ratio. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a piezoelectric actuated fuel injector maintaining the lifetime of an piezoelectric element and increasing the piezoelectric stroke. SOLUTION: A method of operating the fuel injector comprises steps of: (a) reducing the voltage across the actuator at an initial rate (RT0; RT0') so as to de-energize the actuator prior to an initial fuel injection event; (b) increasing the voltage across the actuator at a first rate (RT1) in order to initiate initial fuel injection events (110; 120; 130); (c) reducing the voltage across the actuator at a second rate (RT2) in order to terminate the initial fuel injection events; and (d) increasing the voltage across the actuator at a third rate (RT3; RT3'), which is lower than the first rate (RT1) before the next fuel injection event starts after the initial fuel injection event terminates, so as to de-energize the actuator without initiating any injection event.

Abstract:
PROBLEM TO BE SOLVED: To provide a fuel pump that reduces a load applied to a drive member. SOLUTION: A drive member 28a is co-operable with a cam rider 14 to impart axial drive to a plunger 18a to reduce the volume of a pump chamber 22a in use, while permitting lateral sliding movement of the cam rider 14 relative to the drive member 28a. A pumping plunger performs a pumping cycle including a forward stroke and a return stroke. During the forward stroke, the pumping plunger moves between bottom-dead-center and top-dead-center, and fuel within the pump chamber 22a is pressurized to a relatively high level. During the return stroke, the pumping plunger moves between top-dead-center and bottom-dead-center to allow the pump chamber 22a to fill with fuel at relatively low pressure. The pump includes means 32a, 34a for reducing the load on the drive member 28a due to fuel pressure within the pump chamber 22a during the period of the forward stroke for which the relative velocity of sliding movement between the drive member 28a and the cam rider 14 is minimized, thereby to reduce wear of the drive member 28a.
