摘要： An intake system for a vehicle for delivering intake air through separate or discrete intake passages of the intake system into engine cylinders through discrete intake passages. A collector chamber and a resonator chamber connect with an upstream main intake passage and the discrete intake passages. The collector chamber communicates at one end with upstream ends of the discrete intake passages and at its another end, opposite to the one end, with the resonator chamber. The discrete intake passages are clustered or grouped together at their upstream ends and connected as a cluster to the collector chamber.

摘要： An intake system for a multiple-cylinder engine has a plurality of discrete intake passages which are substantially equal to each other in length and are connected to the respective cylinders at their downstream ends. The upstream ends of the discrete intake passages are merged into an integrated chamber, and an upstream side intake passage communicates the integrated chamber with the atmosphere. The integrated chamber has an upstream side end face and a downstream side end face, and the cross-sectional area of the integrated chamber increases from the upstream side end face to the downstream side end face, the upstream side intake passage having opening into the integrated portion in the upstream side end face, and the discrete intake passages respectively having openings into the integrated chamber in the downstream side end face. The area of the upstream side and downstream side end faces of the integrated chamber S.sub.0 S.sub.1, the sum of the areas of the openings of the discrete intake passages into the integrated chamber S.sub.N and the distance H between the upstream side and downstream side end faces of the integrated chamber satisfy the following formulae ##EQU1##

摘要： Discrete intake passages communicating with respective cylinders of a multiple-cylinder in-line engine are merged into an integrated chamber at their upstream ends. The integrated chamber is disposed above the engine and extends substantially horizontally. Each discrete intake passage extends from the engine body, bends upward toward the integrated chamber and is connected to the downstream side end face of the integrated chamber. The discrete intake passages for the cylinders which are positioned relatively near to the integrated chamber are connected to the downstream side end face of the integrated chamber at an upper portion of the end face and the discrete intake passages for the cylinders which are positioned relatively far from the integrated chamber are connected to the downstream side end face of the integrated chamber at a lower portion of the end face.

摘要： Plural cylinders are grouped, for example, into two cylinder groups composed of plural cylinders having each inspiration stroke in an equal distance, and each of the grouped cylinder groups is communicated with a volume chamber. To this volume chamber is connected each of the independent air intake passages extending independently or separately from each of the corresponding cylinder. A first connecting portion is disposed to communicate the individual air intake passages for each of the cylinder groups with each other in a position spaced apart in an equal distance from an intake port. Further, a second connecting portion as a resonant passage is disposed to communicate one first connecting portion with the other connecting portion for each cylinder group.

摘要： A multiple-cylinder engine has first and second groups of cylinders, the firing order being set so that the cylinders in each group do not fire one after another. An intake system for the engine has first and second groups of discrete intake passages which communicate with the respective cylinders in the first and second groups at their downstream ends and with first and second branch intake passage at their upstream ends. A circular passage communicates with the discrete intake passages at their intermediate portions so that all the discrete intake passages communicate with each other through the circular passage, and an on-off valve opens the circular passage when the engine speed is higher than a predetermined value and closes the same when the engine speed is not higher than the predetermined value. The length of each discrete intake passage is such that a first inertia tuning is obtained at a first engine speed lower than a maximum allowable engine so long as the discrete intake passages are not communicated with the circular passage, and the length of the part of each discrete intake passage downstream of the circular passage is such that a second inertia tuning is obtained at a second engine speed higher than the maximum allowable engine so long as the discrete intake passages are communicated with the circular passage.

摘要： An air intake device of an engine has intake pipes connected to each of the engine cylinders divided into first and second groups to prevent the continuance of the intake strokes of adjacent cylinders. A first connecting cavity connected to the first group of cylinders and a second connecting cavity connected to the second group of cylinders are arranged in parallel with each other, for effecting supercharging by utilizing the dynamic effect of intake air into each cylinder. A first communicating passage is connected at one end to a longitudinal end of the first connecting cavity and at the other end to a longitudinal end of the second connecting cavity. A second communicating passage arranged on the same side as the first communicating passage is connected at one end to a side of the first connecting cavity and at the other end to a side of the second collecting cavity. The effective passage length of the first communicating passage is shorter than that of the second communicating passage.

摘要： The supercharged internal combustion engine is so adapted as to set the air-fuel ratio to become a lean air-fuel ratio which is leaner than stoichiometric and lean enough to maximize improvements in a rate of consumption of fuel, for example, to the A/F ratio of 16, when the supercharger exists in such a supercharging region as demonstrating its sufficient degree of supercharging capability. When the air-fuel ratio is made lean in the supercharging region, exhaust gases are recirculated into the intake system of the engine, in addition to a mixed fuel. Preferably, the exhaust gases having lower temperatures are recirculated at the time of a high load of the engine in the supercharging region, while the exhaust gases having higher temperatures are recirculated at the time of a low load of the engine therein.

摘要： Disclosed is an exhaust gas recirculation system for an engine having a high compression ratio or with a supercharger. An outside EGR duct connecting the exhaust system to the intake system is provided with a first control valve, which has a second outside EGR duct bypassing the first control valve. The second EGR duct has a second EGR control valve and a cooler. When the engine exists in an extremely low load state, the first and second control valves are closed to inhibit the outside EGR. In the light load state, the first control valve is opened while the second control valve is closed, thereby allowing recirculation of the EGR gases having high temperature and reducing the pumping loss. In the high load state, the first control valve is being closed while opening the second control valve, thereby increasing a recirculation ratio of EGR gases cooled by the cooler and performing both an improvement of anti-knocking performance and a decrease in pumping loss, as well as reducing the heat load of the exhaust system and within the engine.
