Abstract - The increase of number of vehicles in the world has caused growth of toxic emission. Because of growing environment pollution, the agencies of environmental protection and automotive concerns are searching for the possibilities of emission reduction of harmful substances being result of hydrocarbon fuels combustion. More and more complicated modernisation of presently produced vehicles is performed for the global problem reduction.
One of the methods to reduce emission of toxic components is continuous control over engine elements that are directly or indirectly responsible for level of emission of these components. Introduction of these requirements caused creation of the self-diagnostic definition and utilising innovation definition self-diagnostic:
Self-diagnostic system comparing value of signals from circuit of electronic control device with control values. If the real signal value does not comply with control value, the memory of the control devices records the error code.
Additionally the OBD systems task is to detect damages connected with safety (i.e. detection of faults of the break systems, ABS or air bags). Additional benefits arising from usage of the OBD systems are the possibility of using a so-called black box (or freeze frame) to record certain parameters of the vehicle before an accident occurs and the possibility of the VIN identification number of the vehicle. These additional functions are important to the police, district attorneys, customs and border control entities, insurance companies, etc.
The implementation of the EOBD norm in Poland should be treated as one of the most important stages of the adaptation of Polish legal system in regards to environment protection to the laws, rules and regulations of the European Union.
This paper presents development of catalyst converter monitoring in vehicles with compression ignition engine in light of ecological manageability of automotive engine.
This paper include basic terms and rules of function European On Board Diagnostic (EOBD) in light of large quantity of vehicles in Europe and in the whole world, level of pollution environment and one of method of prevention degradation environment.
