摘要： The purification system comprises a particle filter to entrap particles in the exhaust gases which can be regenerated by burning off the particles by means of a fuel supplied and temperature increase of the filter, a fuel injection system to the engine combustion chamber comprising a main injection and a secondary injection to increase the temperature of the filter and a fuel injection system to the exhaust duct upstream of the filter. The purification system comprises: (a) a particle filter to entrap particles in the exhaust gases which can be re-generated by burning off the particles by means of a fuel supplied and temperature increase of the filter; (b) a fuel injection system to the engine combustion chamber comprising a main injection and a secondary injection to increase the temperature of the filter; and (c) a fuel injection system to the exhaust duct upstream of the filter. When a re-generation is necessary, fuel can be supplied to the combustion chamber when the bed temperature of the filter is greater or equal to a primary temperature, and fuel may be supplied to the exhaust duct when the temperature of the gases is greater or equal to a secondary temperature and the bed temperature is greater or equal to a third temperature. An Independent claim is also included for the purification process.

摘要： The system consists of an NOx occlusion element in the exhaust pipe from the engine to absorb carbon monoxides from the exhaust gases when the air/fuel ratio in the gases is high and evacuate the absorbed carbon monoxides when the oxygen concentration in the exhaust gases is low. It has a feeder to deliver a reducing agent upstream of the occlusion element in specific conditions, a corrector for the delivered quantity of reducing agent, and a regulator to halt the correction of the reducing agent feed for a predetermined period of time following the commencement of its delivery by the feeder, The reducing agent is delivered when the occlusion element heeds regenerating after poisoning with SOx due to the content of sulphur oxides in the exhaust gases, with the corrector converging the quantity of reducing agent delivered with the amount required to regenerate the occlusion agent, and the correction halted for a predetermined period of time from commencement of the feed.

摘要： The objective of the present invention is to reduce the impact of condensed water on an EGR device. This device (100) controls a cooling system equipped with an adjustment means capable of adjusting the amount of cooling water circulating in a first flow path, which includes an engine cooling flow path, an EGR cooling flow path, and a radiator flow path, and a second flow path, which includes the engine cooling flow path, the EGR cooling flow path, and a bypass flow path, but does not include the radiator flow path. This control device is equipped with: an identification means that identifies the temperature of the cooling water; a restriction means that restricts the circulation of the cooling water when the internal combustion engine starts up; and a control means that preferentially circulates the cooling water in the second flow path by controlling the adjustment means on the basis of the identified temperature during the period when circulation of the cooling water is restricted.

摘要： There is provided a compression ignition type gasoline engine operable under a stable lean burn condition with a high compression ratio, and which has a simple construction without using a pre-heating system for an air-fuel mixture. An intake port (5) communicates with a combustion chamber via an opening. The opening is closed by an intake valve (7). A fuel injection valve (9) is provided in the intake port (5) so as to inject an amount of gasoline inside the intake port (5) within a duration in which the opening is substantially closed by the intake valve. Heat is generated in the mixture in the combustion chamber by means of a high compression ratio so that the mixture is self-ignited only by heat generated by compression. The compression ratio ranges from about 14 to about 20.
