Abstract: A system and method for engine control determine a spilled fuel quantity for use in controlling pressure of a common rail fuel system. In one embodiment, a spilled fuel estimate is determined based on rail pressure and engine speed. Another embodiment determines a spilled fuel estimate based on a leakage quantity and a spill control quantity. The leakage quantity represents the amount of fuel leaked past the internal passages inside the injectors and is based on rail pressure alone. The spill control quantity is based on rail pressure and injector energizing time. The spill control quantity represents the fuel used to actuate the injector allowing the injected fuel into the cylinder during the combustion cycle. A more accurate determination of the quantity of fuel pumped based on spilled fuel and injected fuel may be used to improve the common rail pressure control, for example.

Abstract: A method for determining the rail pressure of an injector including a voltage-controlled piezoelectrical actuator, the piezoelectrical actuator actuating a nozzle needle using hydraulic coupler. As a result of the pressure in the high-pressure channel, a coupler pressure is built up via the hydraulic coupler, the coupler pressure inducing a piezovoltage in the actuator. Because this voltage value is redundant with regard to the pressure value in the high-pressure channel, which is measured by a pressure sensor, the voltage value is used for monitoring the functioning of the pressure sensor. In the event of the failure of the pressure sensor, emergency operation is built up for the injector with the assistance of the induced voltage. The injector advantageously functions for injecting fuel in an internal combustion engine.

Abstract: A counter-flow prevention valve is disposed within a body of a pilot-type channel valve. While electrical power is applied to a solenoid coil and the pilot-type channel valve is opened, i.e., while a gas is flowing through the counter-flow prevention valve and the gas is expanding, heat generated by the application of electrical power to the solenoid coil is conducted via the body and is effectively transferred to the counter-flow prevention valve. Therefore, even if the gas contains water vapor and even if this gas is cooled due to significant expansion, the water vapor can be prevented from freezing within the counter-flow prevention valve. Moreover, the volume of the pipe between the pilot-type channel valve and the counter-flow prevention valve is small, thereby resulting in a fast rise in pressure within the pipe and a quick opening of the counter-flow prevention valve, which provides an excellent valve-opening response.
