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： A turbocharged engine is provided with a waste gate valve which limits the supercharging pressure in the intake passage downstream of the compressor of the turbocharger not to exceed a predetermined value. The intake passage has first and second pressure propagating paths downstream of the compressor. The pressure wave generated by the intake stroke of the combustion chamber is propagated substantially along the first pressure propagating path when the engine operates at a speed in a low engine speed range under heavy load and substantially along the second pressure propagating path when the engine operates at a speed in a high engine speed range. The part of the intake passage defining the first pressure propagating path is arranged so that a supercharging effect by a kinetic effect of intake air which becomes maximum at a predetermined engine speed in the low engine speed range can be obtained, and the part of the intake passage defining the second pressure propagating path is arranged so that a supercharging effect by a kinetic effect of intake air is better in the high engine speed range when the pressure wave is propagated along the second pressure propagating path than when the pressure wave is propagated along the first pressure propagating path. The predetermined engine speed is lower than an intercept engine speed for the second intake path.
