In gasoline engines, the following components should be monitored:

Д›oost pressure control system monitoring.

Дњrankcase ventilation (CV) system monitoring.

Nitrogen Oxide (NOX) converting catalyst monitoring.

Non-Methane Hydrocarbon (NMHC) converting catalyst monitoring.

Monitoring is performed in the appropriate ECU by means of software functions, and the result of the monitoring function should be a report to an external diagnostic device in the format specified by the standard.ДЇor diesel engines, OBD regulations state that the following components be monitored: OBD regulations state that all systems and components related to exhaust gas emission levels must be monitored for malfunction. Onboard Monitoring Functions & Communication Protocols After the transition phase, only the WLTP cycle is applicable. The regulations allow the use of performance monitoring of the DPF, via delta pressure, for example, in place of monitoring against the PM OBD threshold.ДЇor light vehicles, manufacturers have the flexibility to choose NEDC or WLTP cycle for OBD threshold part creation as well as for demonstration testing during the transition phase.Дќuring phase-in period, manufacturers are not required to comply with minimum in-use performance ratios.Дќuring phase-in period, there are no in-use requirements for the OBD system.

Manufacturers are allowed to activate driver warning systems based on more relaxed deviation from typical urea consumption rates - 50% instead of 20% at the final date.

Manufacturers are allowed to define a reagent concentration for threshold monitoring different to that ultimately specified.

Дљdditional monitoring requirements for EGR flow, EGR cooling system, boost (turbo and superchargers), and fuel injection systems.Дuring the Euro VI OBD phase-in period, manufacturers were granted several areas of flexibility, including:.The regulation established a minimum IUPR of 0.1 (1 in 10 times). IUPs give an idea of how often the conditions subject to monitoring occurred and how frequently the monitoring was conducted. More stringent OBD threshold values and type approval based on the World Harmonized Test Cycle.For example, in heavy-duty vehicles, Euro VI OBD requirements include: OBD requirements have increased with each stage of Euro emission regulations, with the Euro VI OBD requirements (2013/16) adding a variety of improvements to previous legislation. This leads to a requirement for a robust system including sensors, software and hardware to ensure malfunctions, failures and defects can be swiftly diagnosed. The OBD standard specifies that if there is a failure with any system or component which results in increased levels of emissions, the driver must be warned through the MIL (Malfunction Indicator Lamp). The use of diesel particulate filters has dramatically reduced harmful toxic exhaust gas emissions and similar technology is being implemented in gasoline direct injection engines via gasoline particulate filters.Д®uro VI regulations, however, also include tighter onboard diagnostics standards for monitoring powertrain components and systems whose functionality has an impact on exhaust gas emission levels. As emission regulations become more stringent, so the need for onboard diagnostics and monitoring systems increases.
