939011784 - 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 service 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 managed by the engine management control unit on the basis of information provided by the sensors and if the following conditions are satisfied: vehicle speed above 40 Km/h for at least 15 minutes and particle mass below 200%.During the procedure the engine management control unit increases the engine speed to 3500 rpm and activates the fans for about 5 minutes; a message is sent at the end and is shown on the panel display. | There may be a limited increase in the engine speed during the regeneration, a limited increase in fumes and high temperatures at the exhaust. These situations should not be interpreted as problems and have no adverse affect on the behaviour of the vehicle or on the environment. |
