摘要： An engine is provided with a mechanical supercharger which is disposed in an intake passage of the engine and is driven by the output power of the engine. The supercharger is connected to and disconnected from the output power of the engine by a clutch. The engine has intake and exhaust valves which are opened and closed with an overlap time. A valve timing changing mechanism changes the overlap time in order to change the amount of air communicated between the intake and exhaust ports. A controller controls the valve timing changing mechanism and the clutch so that the amount of air communicated between the intake and exhaust ports is reduced and the supercharger is disconnected from the output power of the engine and does not operate when the operating condition of the engine is in a first operational range in which the amount of intake air is not more than a first preset value, the former is increased and the latter is connected with the output power of the engine so as to operate when the operating condition of the engine is in a second operational range in which the amount of intake air is not less than a second preset value which is larger than the first preset value, and the former is increased and the latter is disconnected from the output power of the engine when the operating condition of the engine is in a third operational range in which the amount of intake air is between the first and second preset values.

摘要： An improved intake system in an internal combustion engine of a high compression ratio capable of producing a swirl of air-fuel mixture so as to increase the combustion speed thereof for improved combustion efficiency and hence fuel economy during light-load operation of the engine, and at the same time of effectively suppressing the generation of a swirl so as to reduce the level of combustion noises to a substantial extent during heavy-load operation of the engine at full-open throttle. The engine has a combustion chamber defined in a recess in the cylinder head above the top of a piston, slidably received in a cylinder bore in the cylinder block, at its top dead-center, with a squish area of a limited clearance formed adjacent the combustion chamber in the cylinder bore between the cylinder head and the piston. An intake passage in the cylinder head leading to the combustion chamber for supply of air-fuel mixture comprises a light-load intake passage for admitting the mixture into the combustion chamber or the squish area in the circumferential direction of the cylinder bore so as to produce a swirl under light-load operation of the engine, and a heavy-load intake passage having a valve adapted to be closed during light-load operation of the engine and opened during heavy-load operation of the engine for admitting the mixture into the combustion chamber or the squish area in the direction parallel to the central axis of the cylinder bore so as to suppress the generation of a swirl.

摘要： Disclosed is a supercharged direct-injection engine, which comprises a supercharging device (25, 30) for compressing intake air, and an injector 10 for directly injecting fuel into a combustion chamber 5. In the engine, an excess air factor λ as a ratio of an actual air-fuel ratio to a stoichiometric air-fuel ratio, at least in an engine warmed-up mode, is set to 2 or more in the entire engine-load region. Further, compressed self-ignited combustion is performed in a low engine-load region, and a supercharging amount by the supercharging device (25, 30) is increased along with an increase in engine load in a high engine-load region to allow the excess air factor λ to be kept at 2 or more. The engine of the present invention can effectively reduce NOx emission, while improving fuel economy.

摘要： The invention is intended to provide improved emission-cleaning performance by use of a three-way catalyst alone, without the need for a lean NOx catalyst, while ensuring a fuel economy improvement effect of lean burn operation. A multicylinder spark-ignition engine is constructed such that, in a pair of preceding and following cylinders whose exhaust and intake strokes overlap each other, burned gas discharged from the preceding cylinder (2A, 2D) which is currently in the exhaust stroke is introduced directly into the following cylinder (2B, 2C) which is currently in the intake stroke through an intercylinder gas channel (22) and gas discharged from only the following cylinder (2B, 2C) is led to an exhaust passage (20) provided with a three-way catalyst (24) in a low-load, low-speed operating range. Fuel supply to the individual cylinders is controlled in such a manner that combustion in the preceding cylinder (2A, 2D) is made under lean mixture conditions at an air-fuel ratio larger than the stoichiometric air-fuel ratio by a specific amount and combustion in the following cylinder (2B, 2C) is made under conditions of the stoichiometric air-fuel ratio created by supplying fuel to the burned gas introduced from the preceding cylinder (2A, 2D).

摘要： A control system for an engine with a turbo supercharger includes a first switching device for switching an introduction of intake gas to the engine in accordance with engine speed between a first intake condition, in which a charging efficiency of the intake gas is improved in a lower engine speed condition, and a second intake condition, in which the charging efficiency of the intake gas is improved in a higher engine speed condition. The control system also includes a second switching device for switching a maximum supercharging pressure of the turbo supercharger from a lower pressure to a higher pressure in response to a switching operation between the first intake condition and the second intake condition. An improved charging efficiency of the intake gas can be obtained in a broader range of the engine speeds reducing the maximum supercharging pressure of the intake gas, thereby preventing knocking of the engine.

摘要： An intake-exhaust control system includes a mechanism for changing timings at which the open periods of intake and/or exhaust valves overlap. A control unit cooperates with the valve timing changing mechanism to cause it to change the timing stepwise so as to vary the valve overlap in time, or in degrees, in a plurality of steps according to engine operating conditions, such as engine speed and engine load. The valve overlap, when the engine operates under medium or moderate engine speeds, is varied so as to be larger or longer under medium engine loads than under higher or heavier and lower or lighter engine loads.

摘要： An intake system for a multi-cylinder internal combustion engine having an intake manifold that is made up of a common intake passage and separate intake passages that branch off from the common intake passage and connect to intake ports of the engine cylinders. An upstream throttle valve is located in the common intake passage. Downstream throttle velves located in the separate branched intake passages near the intake ports. A controller controls intake air actually introduced into the cylinder by actuating the downstream throttle valves to throttle down, smaller than the upstream throttle valve in a light engine load range and by actuating the upstream throttle valve to throttle down smaller than the downstream throttle valves in a heavier engine load range.
