摘要： An internal combustion engine comprising an intake duct and a turbocharger arranged in the intake duct. A primary throttle valve connected to the accelerator pedal is arranged in the intake duct located downstream of the turbocharger. A secondary throttle valve is arranged in the intake duct located downstream of the primary throttle valve. An auxiliary intake passage is branched off from the intake duct located between the primary and the secondary throttle valves and is connected to the intake passage located downstream of the secondary throttle valve. The secondary throttle valve is gradually closed from the full open position as the level of the vacuum or the positive pressure, which are produced in the intake duct located between the primary and the secondary throttle valves, is increased.

摘要： An internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chamber is filled with catalyzer pellets for reforming the combustible mixture accumulated in the accumulation chamber. The accumulation valve is opened during the compression stroke. In the first half of the compression stroke, a jet of the reformed combustible mixture is spouted into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber where the combustible mixture accumulates under high pressure, and the mixture is then spouted into the combustion chamber at the next cycle, from the accumulation chamber.

摘要： Disclosed is a method for controlling the ignition timing in an internal combustion engine provided with an EGR device. In this method, the correct EGR ratio of the engine is obtained by means of a specific calculation using a measured absolute pressure value in an intake manifold of the engine where EGR gas is recirculated and using a calculated absolute pressure value in the intake manifold where no EGR gas is recirculated, according to the engine's operating conditions. The optimum ignition timing in the engine is controlled in accordance with the calculated EGR ratio.

摘要： Disclosed is an internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via a valve. The opening operation of the valve is controlled so that the valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle, in the accumulation chamber.

摘要： An engine exhaust gas recirculation system has an E.G.R. passage for recirculating exhaust gases from an exhaust system of an engine back into an intake system thereof downstream of a throttle valve. The E.G.R. passage has a restriction orifice therein and an E.G.R. control valve responsive to a vacuum signal to control the recirculation of exhaust gases through the E.G.R. passage. A pressure comparator and modulator is pneumatically connected to the E.G.R. passage upstream and downstream of the restriction orifice, to the carburetor venturi, to the intake manifold and to the E.G.R. control valve and operative to compare the venturi vacuum with the exhaust gas pressure difference across the restriction orifice thereby to modulate the intake manifold vacuum to be fed to the E.G.R. control valve so that the latter is controlled by the thus modulated vacuum to keep the exhaust gas pressure difference proportional to the venturi vacuum whereby the volumetric quantity of recirculated exhaust gases is made proportional to the volumetric quantity of engine intake air.
