摘要： An IC engine for reducing NOx in the exhaust gases comprises a precombustion chamber(7), a main combustion chamber (4), a main inlet valve, and an aux. inlet valve(23). A spark plug is located in a residual gas chamber communicated with the precombustion chamber via a restricted opening(11). A control is provided to vary the size of this linking opening. The control is arranged to only vary the size of the opening during the intake stroke of the piston, and progressively decreases the size of the opening as the engine load rises from idling to at least medium load. The control comprises a skirt(62,63) on the head of a movable valve member.

摘要： PURPOSE: An EGR(exhaust gas recirculation) cooler for a vehicle is provided to primarily cool exhaust gas which is recirculated from the exhaust manifold of an engine into an intake manifold to flow into an EGR valve as cooling water. CONSTITUTION: An EGR cooler for a vehicle(100) comprises a main cooling unit(10), a valve assembly(40), and a sub cooling unit(70). The main cooling unit cools exhaust gas which is circulated from the exhaust manifold of an engine into an intake manifold through cooling water. The valve assembly controls the amount of the exhaust gas which flows in the first exhaust gas route(31) of the main cooling unit. The sub cooling unit primarily cools the exhaust gas which is circulated from the exhaust manifold of the engine into the intake manifold to flow into the valve assembly with the cooling water.

摘要： PURPOSE: An exhaust gas recirculation-venturi diesel injection system is provided to restrict air supply, thereby more quickly implementing an engine cut-off process in which much less noise is generated. CONSTITUTION: An exhaust gas recirculation(EGR)-venturi diesel injection comprises an air conduit(20), a valve body(52), and a fuel injector. The air conduit is equipped with an inlet for the flow of a first gas and a reduced portion and is a path through which air flows to an engine. The valve body is displaceable in the length direction of the air conduit in order to obtain a variable venturi effect for a variable suction. One or more than one fuel injector for injecting fuel inside the air conduit is placed on the valve body or the upper stream of the valve body. The fuel injected inside the air conduit is mixed in the gas flow and then forms a mixture before flowing to the engine for combustion. The fuel is diesel fuel. At least one fuel injector is placed to be adjacent to the air conduit. [Reference numerals] (AA) Inlet part or atmosphere; (BB) Emergency cut-off signal
