An exhaust-gas probe is mounted rearward of the catalytic converter and at least one misfire of a combustion of the engine is stimulated. The reaction of the exhaust-gas probe to the stimulation of the misfire is evaluated to diagnose the catalytic converter. The invention is also directed to...
The invention is directed to a method for evaluating the operability of a catalytic converter mounted in the exhaust-gas system of an internal combustion engine. In the method, the actual value of a signal of an exhaust-gas probe mounted downstream of the catalytic converter is detected and an...
The invention relates to a method and to a motor vehicle for diagnosing an exhaust gas catalytic converter (28), which is arranged in an exhaust gas tract (20) of an internal combustion engine (12) and is suitable for converting at least one exhaust gas component, wherein the exhaust gas...
It may or may not indicate converter problems. This test can be performed using any suitable engine vacuum source. After the vacuum gauge is connected to a vacuum source, readings are noted at idle and then again at 2,500RPM. As engine speeds vary, readings should initially drop slightly,...
The invention is directed to a method for evaluating the operability of a catalytic converter mounted in the exhaust-gas system of an internal combustion engine. In the method, the actual value of a signal of an exhaust-gas probe mounted downstream of the catalytic converter is detected and an...
A predetermined threshold value on a correct function of the catalytic converter is closed at a polarization voltage. Independent claims are also included for the following: (1) a computer program; and (2) a computer program product.REINHARDT, GOETZ...
A catalytic diagnostic apparatus for determining whether a catalyst of an internal combustion engine has deteriorated as disclosed. Air-fuel ratio sensors are placed at the upstream and downstream sides of the catalytic converter, and the output signal from the upstream air-fuel sensor is used to ...
