“…Montes and Pisu used a fault detection method for the idle speed control of an internal combustion engine. [23] The proposed approach is based on residual generators using the parity equation and an active threshold calculation technique. Simulation results show 100 % fault detection during nominal temperature conditions, and 89.6 % fault detection during the initial operating stage of the engine.…”

“…We can outline the following devices in the group of special devices and appliances: exhaust gas leakage detectors, thermocouples as a single set and thermal imagers, pressure sensors in the exhaust manifold, and some others [18,20,22,23]. The main advantage is the selectivity of control by the diagnostic tools and low cost.…”

The toxicity standards of modern cars are constantly tightening. Such standards can be reached only when using special systems and assemblies. The existing diagnostic methods are too time-consuming and do not exclude possible multiple errors. The article proposes a method for diagnosing the ICE (internal combustion engine) exhaust system of cars by the run-down time in test modes. An active study of possible diagnostic parameters allowed us to identify a sensitive diagnostic parameter -the run-down time. As the resistance of the catalytic converter increases, the run-down time decreases significantly. The experimental test showed the following: 1) when the run-down starts from 5,000 rpm, the run-down time in case of reaching the limiting resistance of the catalyst is halved -from 4.8 to 2.4 s; 2) in case of a limiting change in the resistance of the catalytic converter from 34 to 10 mm in the exhaust gases, the O2 content increases from 2.53 to 4.92 %, the CO2 content decreases from 13.17 to 12.57 %, and there is a sharp decrease in CH from 100 to 8 ppm. The run-down parameters control range is from 15 to 0.1 s. The production test of the new method for diagnosing the ICE exhaust system showed its significant performance.

“…The non-linear parity generation method [53] and parameter estimation methods (based on an auto regressive moving average (ARMA) model) were used to detect and isolate process coefficient faults in electronic throttle control systems. Monte and Pisu [54] presented a fault-detection method for the idle speed control of an IC engine considering throttle faults and manifold pressure sensor fault, where the proposed approach is based on the residual generators using the parity equation and an active threshold calculation. It is noted that parity equations require less computational effort, but do not provide as much insight into the process as parameter estimation schemes.…”

Faults affecting automotive engines can potentially lead to increased emissions, increased fuel consumption, or engine damage. These negative impacts may be prevented or at least alleviated if faults can be detected and isolated in advance of a failure. United States Federal and State regulations dictate that automotive engines operate with high-precision onboard diagnosis (OBD) systems that enable the detection of faults, resulting in higher emissions that exceed standard thresholds. In this paper, we survey and discuss the different aspects of fault detection and diagnosis in automotive engine systems. The paper collects some of the efforts made in academia and industry on fault detection and isolation for a variety of component faults, actuator faults, and sensor faults using various data-driven and model-based methods.
