Latest Patents

One of his latest patents is titled "System, method, and apparatus for aftertreatment system monitoring." This method involves determining whether a urea refill event is detected, clearing a quality accumulator value, and clearing a latching abort command. The process includes checking for urea fluid quality check abort conditions, clearing the urea quality accumulator, latching the abort command, and exiting the reductant fluid quality check. If the abort conditions are not met, the method increments the urea quality accumulator based on the amount of urea injected and compares the accumulated urea quantity to a low test threshold. Furthermore, if the accumulated urea quantity exceeds this threshold, it is compared to a high test threshold. In cases where the urea quantity surpasses the high test threshold, the method determines whether a NO exceedance is observed and clears a urea quality error if the NO exceedance is not observed.
