摘要： A method of control of the supply of lubricating oil to a two stroke cycle internal combustion engine comprising supplying fuel to a fuel injector from a fuel reservoir having a fuel capacity greater than the maximum fuel requirement of the engine per cycle. The fuel in the reservoir being maintained at a substantially steady pressure. Delivering oil to the engine by a positive displacement pump having a delivery capacity per pump cycle greater than the maximum oil requirement of the engine per cycle. The oil pump being activated in response to the consumption of fuel from the fuel reservoir to maintain a substantially uniform predetermined ratio between the fuel consumption rate and the oil delivery rate.

摘要： A method and apparatus for metering liquid fuel for delivery to an engine including delivering during each cycle a predetermined quantity of liquid fuel into a control chamber (71) charged with compressed gas, and thereafter, adjusting the quantity of fuel in the control chamber (71) in accordance with the engine load and/or speed to the required quantity per cycle, and discharging the adjusted quantity of fuel from the control chamber (71) to an injection chamber (70) charged with compressed air for delivery to the engine combustion chamber. Conveniently, as the quantity of fuel is maintained in said control chamber (71) under pressure, the adjustment of the quantity of fuel is effected by opening a bleed valve (73) for a time period determined by the quantity of fuel required to be retained for delivery to the engine. A method and apparatus for metering fluids for cyclic delivery in variable discrete quantities are also disclosed.
摘要翻译：一种用于计量用于输送到发动机的液体燃料的方法和装置，包括在每个循环期间将预定量的液体燃料输送到装有压缩气体的控制室（71）中，之后调节控制室（71）中的燃料量）根据发动机负载和/或速度达到每循环所需量，并且将调节量的燃料从控制室（71）排出到装有压缩空气的喷射室（70），以输送到发动机燃烧室。方便地，当在压力下在所述控制室（71）中保持燃料量时，燃料量的调节通过打开放气阀（73）达到由所需要的燃料量所确定的时间段来实现送到发动机。还公开了用于以可变离散量计量循环递送的流体的方法和装置。

摘要： A method of operating a fuel system having a fuel pump (15) to supply fuel to a fuel metering apparatus (23) operable to provide metered quantities of fuel for injection to an engine, and an electronic controller (22) responsive to a plurality of input signals to determine the engine fuel demand and to control the activation of the fuel metering apparatus (23) to deliver a quantity of fuel to meet said fuel demand. The method comprising maintaining a fuel supply to said fuel metering apparatus (23) within predetermined fuel pressure or fuel level parameters, and cyclically operating said fuel pump (15) to maintain said fuel supply within said parameters. Further providing a signal from a sensor (18) to the electronic controller (22) indicative of the pressure of the fuel supply at the fuel metering apparatus (23) as one of said input signals to be processed by the electronic controller (22) in the control of the fuel metering apparatus (23). The pump (15) preferably provides fuel to a closed chamber that acts in the manner of an accumulator (16), and the pressure sensor (18) provides an input signal to the electronic controller (22) indicative of the pressure of the fuel available to the fuel metering apparatus (23) from the accumulator (16). Alternatively, the chamber may maintain the fuel between predetermined levels at a substantially steady or variable pressure.
