The invention relates to a method for operating a compressed air system of a vehicle, with an electronically controlled air drying device which has at least two drying cartridges that operate in mutual alternation or independently of one another in a deliv...

The operation of air compressor is controlled to control engine performance to thereby improve the performance of the vehicle. A compressor (4) driven by the engine (3) of a vehicle and supplying compressed air to loads (51-54) is controlled by an ECU (2),...

The method involves regenerating air dryer with compressed air from a compressed air circle, if that pressure lies within compressed air circle when target pressure value and a humidity value of the air dryer reached over a pre-determined target humidity v...

An operational status of apparatus for adsorbing and desorbing pollutants is monitored by adsorbing pollutants in filter in adsorbing mode, desorbing pollutants to engine during desorption mode, and generating error signal if amount desorbed differs from a...

The compressed air distribution device has several circuits with overflow valves (18), at least one with a third working surface (33) in addition to two incident flow working surfaces (22,27) on a moving wall. At least the overflow valve with a third worki...

A first heat-resistant filter medium is disposed in an exhaust pathway of an internal combustion engine. The first heat-resistant filter medium traps hydrocarbon compounds and carbon-containing particulates included in a flow of exhaust gas in a dispersive...

In a hydrogen generator comprising a reforming unit having a material supply unit and a water supply unit, and a burner for heating the reforming unit, having a fuel supply unit and an air supply unit, a control unit is arranged for controlling the amount ...

Sensors (S1,S2) are positioned before and after the filter unit (15) to measure the contamination levels which are fed to a control unit (18) with indicator lamps (21,22). The difference in readings is compared to the output reading to indicate whether the...
