摘要： A fuel control system that regulates a purge flow from a fueling system to an engine includes a sensor that monitors an engine speed and a first module that determines a PWM frequency of a purge valve based on the engine speed. The PWM frequency includes a first period that is based on a second period that corresponds to two engine cycles. A second module regulates the purge valve based on the PWM frequency during engine operation.

摘要： An idle air control system diagnostic for an internal combustion engine which utilizes RPM, engine timing and intake airflow measurements to detect the presence of idle RPM faults and eliminate or verify the idle air control system as the fault source. Engine idle RPM is measured and compared with a commanded idle RPM, and if within a predetermined range, an idle RPM fault exists and one of two additional tests (non-intrusive and intrusive) is conducted to determine whether the idle air control system is the source of the fault. In the non-intrusive test, intake airflow is measured and compared to a predetermined intake airflow value, and if not within a predetermined range, the idle air control system is determined to be the fault source. In the intrusive test, variations in intake airflow (or intake manifold pressure) are measured in response to variations in the movement of the engine throttle-bypass airway pintle. If no intake airflow variations are detected, the idle air control system is determined to be the fault source.
摘要翻译：用于内燃机的空闲空气控制系统诊断装置，其利用RPM，发动机正时和进气流量测量来检测空转RPM故障的存在并消除或验证怠速空气控制系统作为故障源。发动机空转RPM被测量并与指令的空转RPM进行比较，并且如果在预定范围内存在空转RPM故障，并且执行两个附加测试（非侵入式和侵入式）之一，以确定怠速空气控制系统是否为来源的故障。在非侵入式测试中，测量进气气流并将其与预定的进气流量值进行比较，如果不在预定范围内，则空转控制系统被确定为故障源。在入侵测试中，根据发动机节气门旁路气道枢轴的运动变化来测量进气气流（或进气歧管压力）的变化。如果没有检测到进气气流变化，则空转控制系统被确定为故障源。

摘要： A comprehensive air injection system diagnostic uses hardware already available on many vehicle exhaust systems to monitor the oxygen content of the exhaust, so as to indicate steady state oxygen levels therein that are not in accord with the present state of the air injection system, and accordingly are assumed to be the result of a failure in the air injection system.
摘要翻译：全面的空气喷射系统诊断使用许多车辆排气系统上已经可用的硬件来监测排气的氧含量，以便指示其中不稳定的氧气水平与空气喷射系统的当前状态不一致，因此被认为是空气喷射系统故障的结果。
