Exhaust gas purification system of internal combustion engine

An electronic control unit (ECU) of an internal combustion engine calculates a present deposition quantity of exhaust particulate matters based on operating states of the engine such as a differential pressure of a diesel particulate filter (DPF). If the present deposition quantity exceeds a predetermined upper limit value, the ECU performs compulsory regeneration of the DPF to compulsorily combust and reduce the deposited exhaust particulate matters. The ECU determines that spontaneous regeneration occurs if a temperature of exhaust gas in the DPF is equal to or higher than a reference temperature. Thereafter, the ECU completes the compulsory regeneration to eliminate the deposited exhaust particulate matters if the ECU determines that the spontaneous regeneration stops and the deposition quantity becomes equal to or less than a predetermined lower limit value.

Gasoline internal combustion engine, with a combustion pre-chamber and two spark plugs

An engine has, for each cylinder, a combustion chamber and a combustion pre-chamber communicating with the combustion chamber. First and second spark plugs are associated with the pre-chamber and combustion chamber, respectively. Gasoline is injected by an injector device directly into the combustion chamber and / or by an injector device into a cylinder intake duct. There is no device for injecting gasoline, air or an air / gasoline mixture directly into the pre-chamber. The engine operates with an air / gasoline mixture substantially corresponding to stoichiometric for compatibility with an exhaust system having a trivalent catalyst. The pre-chamber is, not used for engine operation with poor dosing, but to increase resistance to engine detonation. The engine can thus be configured with a high compression ratio, with a significant reduction in fuel consumption at the same power level. The second spark plug is only activated at low and medium engine loads to stabilize combustion.
