A monitoring system and method for detecting clogging through fouling of an air filter (3) of an internal combustion engine (5) comprising a differential pressure sensor means (7) for determining a differential pressure between an ambient environment and a position directly downstream of the air inlet filter. The system further comprising at least one exhaust flow sensor means (9) for determining the exhaust flow, and a controller (13) which is communicatively connected to each of the sensor means for processing information therefrom. The controller is arranged for determining a first filter resistance coefficient based on, at least, a measurement of the differential pressure, and the exhaust flow. The system is arranged for, using the controller, to calculate a second filter coefficient based on the historic evolution of the first filter coefficient, the controller further arranged for comparing the second filter coefficient to a boundary value, and generating a clogging alarm signal when the second filter coefficient exceeds said boundary value.

A deterioration determination apparatus is usable with an ammonia sensor that includes an ammonia element portion that includes, a solid electrolyte, an ammonia electrode, and a reference electrode. The deterioration determining apparatus compares a first evaluation value and a second evaluation value, and determines whether deterioration has occurred in the ammonia element portion of the ammonia sensor at an evaluation time or subsequent to the evaluation time. The first evaluation value is based on a first sensor current obtained when a DC voltage is applied between the ammonia electrode and the reference electrode of the ammonia element portion at an initial time that is during an initial use period of the ammonia sensor. The second evaluation value is based on a second sensor current obtained when the DC voltage is applied between the ammonia electrode and the reference electrode subsequent to the initial period of use of the ammonia sensor.

A phase diagnosis method and apparatus. When it is verified that the location of an engine is valid, an oil injector performs spraying at a top center compression position; if no acceleration is detected after spraying, it indicates that a fault occurs; in order to detect whether it is a fault of phase deviation of the camshaft by 180 degrees, the oil sprayer performs spraying at the top center exhaust position and detects whether there is an acceleration; if an acceleration is detected, it indicates that the situation of the phase deviation of the camshaft by 180 degrees exists. In this way, the problem in the prior art of being unable to detect phase deviation when the phase of a camshaft is deviated by 180 degrees is solved.

A system and method of controlling a turbocharged engine system includes receiving a boost mode selection signal and controlling the turbocharged engine system in response to the boost mode selection signal.

Methods and systems are presented for diagnosing a breach of an evaporative emissions system. The methods and systems include repurposing a resonator as a vacuum reservoir to reduce a pressure of an evaporative emissions system so that it may be determined if there is or is not a breach of the evaporative emissions system.

In a case where a determination is made, after an engine is started based on a remote operation, that an ambient environment of a vehicle is not a predetermined appropriate environment based on a detection value from an ambient environment detection sensor configured to detect the ambient environment of the vehicle, the engine is stopped. As a result, it is possible to suppress a deterioration of an environmental state around the vehicle or an occupant cabin. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.

A cleaning system for removal of contaminants from a surface of a vehicle component exposed to a gas or fluid flow, the cleaning system comprising: an excitation device adapted to be attached to the vehicle component in the vicinity of the surface exposed to contaminants, wherein the excitation device is configured to cause the surface to mechanically vibrate by transferring a vibrational excitation to the surface; wherein the frequency of the vibrational excitation is controllable to be based on the configuration of the vehicle component as well as other modelled/measured parameters.
