Latest Patents
Douglas Shears holds a patent for an "Electronic engine load and revolution sensing device." This device automatically determines whether a load is being applied to the engine and outputs a change signal that is used to adjust one or more engine operating parameters accordingly, such as engine speed, engine timing, or fuel flow. The innovation allows for load sensing without the need for a manifold pressure or throttle plate position sensor, thereby reducing the overall cost of the system. The device operates by determining the period of a first crankshaft revolution, followed by a second crankshaft revolution, and computing a difference value that reflects the difference between these periods. This difference value is proportional to engine load and can be compared with a reference value to ascertain whether a load is being applied. The reference value can be preset, manually determined by the operator, or learned by the system's software, allowing for automatic mapping to the specific engine in use.
