Abstract:
A system, an apparatus, and a method for starting an engine. The system, apparatus, and method include determining a first quantity of fuel based on engine temperature, providing the first quantity of fuel to the engine during a first cycle of the engine, determining a second quantity of fuel based on engine temperature, providing the second quantity of fuel to the engine subsequently, and transitioning to an alternative fueling strategy.
Abstract:
A signal conditioning device, user interface, and method of conditioning a signal. The signal conditioning device includes a processor, a first input coupled to the processor and an output coupled to the processor. Instructions are stored within the processor that, when executed by the processor, cause the processor to provide a signal incident at the output that corresponds to a signal incident at the input.
Abstract:
A system, an apparatus, and a method for dynamically filtering a signal, in order to minimize small signal fluctuations while reacting to larger signal fluctuations. The system, apparatus, and method include providing a filtered value comprising a portion of a previously determined value and a portion of a currently determined value, the portions depending on a magnitude of change between those previously and currently determined values, such that the filtered value is biased toward the previously determined value when the magnitude of change is small and biased more toward the currently determined value when the magnitude of change is larger.
Abstract:
A throttle and fuel injector assembly (400) and method of controlling fuel and air supply to an engine. The assembly (400) and method provide combustion air through a carburetor (100) and fuel through an injector (216).
Abstract:
A self-tuning filter is disclosed. The self-tuning filter includes a digital clocking signal and an input coupled to the digital clocking signal, whereby the input reads a value incident on the input when the digital clocking signal changes to a predetermined state. A clock-tunable filter is, furthermore, coupled to the digital clocking signal so that the frequency of the clock-tunable filter is adjusted in relation to a sampling frequency at which the digital clocking signal operates. The self-tuning filter may be applied to an input of a data acquisition unit and applied to an input having a variable sampling frequency. A method of controlling the frequency of a clock-tunable filter is also disclosed.
