摘要： A diesel particulate filter system for treating the exhaust gas of a diesel engine which is small in size and inexpensive. The system includes a particulate filter connected in a gas line from the engine, a burner, including an ignition plug, connected at a point upstream of the particulate filter and which is supplied with fuel, a primary air flow for atomizing the fuel, and a secondary air flow for burning the particulates trapped in the particular filter and which supplies the particulate filter with a hot burning gas produced by the ignition plug. Primary and secondary pumps supply, respectively, the primary and secondary air flows. A single motor drives both the primary and secondary air pumps. The ignition plug and motor are controlled so that when the amount of particulates trapped in the filter exceeds a preset level, the ignition plug and motor are activated to clean the filter by burning the particulates in the burner.

摘要： An internal combustion engine has a combustion chamber which communicates via an injection port with an injection chamber whose volume is 0.5 cc.about.1.5 cc. During the intake stroke, air-fuel mixture is introduced from an intake port into the combustion chamber, and at the same time, under the influence of high vacuum produced in the combustion chamber, a jet stream of exhaust gas, air or air-fuel mixture is violently injected from the injection port into the combustion chamber via an auxiliary intake passage communicates with the injection chamber through an auxiliary intake valve, so that the jet stream enhances the ignitability by scavenging burned gases from around a spark gap and also generates strong swirl and turbulence of air-fuel mixture in the combustion chamber.

摘要： In an internal combustion engine, an injection hole is provided in the cylinder head to inject narrow streams of air towards the spark gap, particularly during idling and low load running conditions. The injected air is 5 to 30% by weight of the intake fuel-air mixture provided via the intake manifold and creates a swirl or turbulence thereby increasing combustibility. The hole is connected via a sub intake passage to the main air intake passage upstream of the venturi in the carburetor or between the venturi and throttle valve.

摘要： A carburetor system for us in a multicylinder engine comprises a carburetor having a main fuel-air mixture supply device to supply a mixture leaner than stoichiometric to at least one first cylinder and a corresponding number of second cylinder. A rich mixture supply device, integrated into the carburetor, has a rich mixture forming passage to make a mixture richer than stoichiometric. The main mixture supply device communicates with the first and second cylinders by a first passage, while the rich mixture forming passage with the second cylinder by a second passage. A first, second and third valves are provided in the first, second and rich mixture forming passages, respectively. These valves respectively are opened and closed by a first, second and third valve actuation devices, which are in turn regulated by an operation control device. Depending on the engine operating range and driving conditions, this carburetor system supplies a rich mixture to the second cylinder to raise the fuel-air ratio in it. By thus feeding both lean and rich mixtures to the engine, this system purifies its exhaust gases.
