  • Patent number: 9506441
    Abstract: The present invention provides, with reference to FIG. 1, an internal combustion engine (10) having a fuel injector which comprises a sprung piston (55) or a resilient diaphragm piston (8155) and an electrical coil (57, 8158) for displacing the piston (55, 8155). The piston draws fuel into and expels fuel from a pumping chamber (52, 8152). The number of operations of the injector per engine cycle is controlled by an electronic controller (23, 8159) to control the quality of fuel delivered per cycle to a combustion chamber. A voltage measured in the coil (52, 8158) by movement of the piston under action of the spring or due to its own resilience is used to give an indication of vapor pressure of the fuel. A device akin to the injector can be used to draw fuel from a pipeline to measure the vapor pressure of the fluid.

  • Patent number: 8701633
    Abstract: The present invention relates to a method of operating an internal combustion engine. With reference to FIGS. (1), (2) and (5), fluid is supplied to charge air using an injector (116, 3116a, 3116b) which in each operation delivers a set amount of fluid. The amount of fluid supplied to the charge air in each engine cycle is controlled by how many times the injector (116, 3116a, 3116b) operates in each cycle. A desired fluid demand is calculated as a number of operations of the injector per cycle, calculated to at least one decimal place. The desired fluid demand is always rounded down or always rounded up to a near integer to provide an output fluid demand for the injector as a number of operations of the injector for the next operating cycle in varying operating conditions of the engine. The rounding difference is aggregated and when the aggregate passes an integer then the fluid demand is adjusted.

The desired fuel demand is rounded to a near integer to provide an output fuel demand for the injector as a number of operations of the injector for the next operating cycle in varying operating conditions of the engine. The controller calculates an aggregate number of operations for a plurality of engine cycles which is closer to an aggregated desired fuel demand for the plurality of cycles than if for each cycle of the plurality of output cycles the output fuel demand is calculated independently.
