198000611 - E5070 PARTICLE FILTER SYSTEM - DESCRIPTION
DESCRIPTION
An electronic control system supervises and governs all engine parameters to optimise performance and fuel consumption by means of a real-time response to different operation conditions. See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT To conform with the most recent pollution control regulations (EURO 4), the most recent version of electronic management which includes new components and a swirl solenoid valve and DPF particle filter has been adopted.The DPF particle filter (Diesel Particulate Filter) is a mechanical filter, inserted in the exhaust pipes which traps the carbon particles present in the exhaust gases on diesel engines. The filter makes it possible to almost totally eliminate the emission of carbon particles in line with current legislation.During the normal usage of the vehicle, the engine management control unit records a series of data related to usage (period of usage, type of journey, temperatures reached, etc.) and empirically calculates the quantity of particulates accumulated in the filter.The filter is an accumulation system and should be periodically regenerated (cleaned) by burning the carbon particles.This regeneration is carried out automatically by the engine management control unit on the basis of information provided by the sensors and if the following usage conditions are satisfied: vehicle speed above 40 Km/h for at least 15 minutes and particle mass below 200%.The following phenomena may occur during the regeneration: limited increase in the idle speed, activation of the fan, limited increase in fumes, high exhaust temperatures. These situations should not be interpreted as faults and do not have an adverse effect on the behaviour of the vehicle or the environment. |
