Title: Salem Ahmad Fayyad: Innovator in Engine Performance Technology
Introduction
Salem Ahmad Fayyad is a notable inventor based in Grand Blanc, MI (US). He has made significant contributions to the field of engine performance technology, holding a total of 4 patents. His innovative work focuses on improving the accuracy and efficiency of crankshaft signal detection and discrimination.
Latest Patents
One of his latest patents is titled "Crank signal error detection using a cam signal interval." This method involves detecting crank signal errors by incrementing a crank tooth counter in response to a crank signal. It compares the counter to an expected value when a cam signal is detected, indicating an error if they do not match. This approach is advantageous as it automatically adjusts for variations in engine speed, unlike previous time-based methods.
Another significant patent is the "System for discrimination of spurious crank encoder signals." This system utilizes a position encoder connected to the engine crankshaft to send pulsed signals indicative of crankshaft performance to an engine controller. The controller triggers an interrupt service routine (ISR) for each pulse, calculating the period and speed of the engine. It recognizes valid signals within a specific time window, rejecting those that fall outside, thereby enhancing engine performance by maintaining synchronization between spark and fuel injection.
