摘要:
The invention relates to an exhaust line (40) of an internal combustion engine comprising an exhaust duct (43) for the burnt gases and a fuel injector (53) giving into said exhaust duct. According to the invention, a plurality of flat vanes (101, 102, 103, 104) are provided in the exhaust duct (43) so that one face of each vane (101, 102, 103, 104) receives a portion of the fuel (54) jet from said fuel injector (53).

The invention relates to a method of controlling elements used to execute the elementary functions (11, 16, 19, 21, 27-31) of internal combustion engines (2). The inventive method consists in: controlling the elements using measurement signals provided by sensors, determining theoretical signals that have to be provided by reference sensors (27, 29) at the current operating point of the engine, determining the deviations between the theoretical signals and the signals measured by the reference sensors (27, 29) and establishing signal correction instructions for the elements (11, 16, 19, 21, 27-31) according to the determined deviations.
摘要:
The invention relates to a method for working out instruction cartography (16) for a temperature at entry into filter consisting in determining for each combination, which comprises a soot mass in a particle filter, a temperature at the filter output, an air flowrate through the filter and a soot combustion rate in the filter and is associated with a time t, a value assignable to the instruction, wherein said value is selected in such a way that the filter output temperature remains less than a maximum permissible temperature after a pedal release at a time t.
摘要:
A particle filter regeneration control method involving filter inlet temperature control, characterised in that said control includes a correction dependent on a measurement of the mass flow rate of the exhaust gases, as determined on the basis of a measurement of the total injected diesel fuel flow rate and the intake air flow rate.
摘要:
The invention concerns a method for controlling an engine (2) comprising an oxidation catalytic converter (4), the method consisting in, if certain criteria are verified, calculating a maximum amount of fuel to be post-injected based on a measured air flow rate and a threshold operating temperature of the oxidation catalytic converter (4).
摘要:
Disclosed is a method according to which a first oxygen sensor (21) is disposed on the exhaust pipe upstream from a nitrogen oxide trap (18), and the development of a meaningful signal that is representative of the signal (3, 4) supplied by said sensor is monitored. A substantial increase (34, 44) of said meaningful signal, which is obtained following a variation (31, 41) resulting from the motor being switched from running on a lean mixture to running on a rich mixture, from a first plate (32, 42) having an essentially constant level is used as an indicator for controlling the end of the purge process. The invention applies to diesel engines.
