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.
摘要翻译：增压内燃机适于将空燃比设定为比理论配比稀薄的稀空燃比，并且足够稀薄以最大化燃料消耗率的提高，例如对A / F比例为16时，增压器存在于这样的增压区域中，表现为充分的增压能力。当空燃比在增压区域中变薄时，除了混合燃料之外，废气再循环到发动机的进气系统中。优选地，具有较低温度的废气在发动机在增压区域的高负载时再循环，而具有较高温度的排气在发动机的低负载时再循环。

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.

摘要： An engine with a row of cylinders is provided with two intake ports and intake valves and two exhaust ports and exhaust valves for each cylinder. The intake ports are arranged on one side of a center line of the row of cylinders, adjacent to each other, and side by side in a direction parallel to the cylinder row. The exhaust ports are arranged on another side of the center line, adjacent to each other, and side by side in the direction parallel to the cylinder row so that their centers are located at a distance apart which is larger than a distance at which centers of the intake ports are separated. The cylinder is formed with a "squish" surface between the exhaust ports which provides a squish area between the cylinder head and piston. This produces a squish or compressed flow of the air-fuel mixture to the exhaust ports in the combustion chamber.

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： An exhaust gas recirculation system of an engine equipped with a supercharger has an exhaust gas circulation passage for circulating exhaust gas into an intake system from an exhaust system, and a return passage for returning exhaust gas introduced into the exhaust gas circulation passage to the exhaust system. The exhaust gas circulation passage is made available to the exhaust gas when the engine operates within a specified area of engine operating conditions in which supercharging is to be effected. The return passage is made available to the exhaust gas when the engine operates within an area, other than the specified area, of engine operating conditions.

摘要： An intake manifold for a multi cylinder internal combustion engine has a common upstream passage and individual downstream passages, leading individually to cylinders of the engine, respectively. These individual downstream passages are connected between a downstream end of the common upstream passage and the cylinders. Upstream end portions of the individual downstream passages are symmetrically located around a fuel injector, disposed downstream relative to the common upstream passage, and are joined together. At a center of the symmetrically joined upstream end portions of the individual downstream passages, fuel passages are provided to open independently into the upstream end portions so as to introduce fuel from the fuel injector into the individual downstream passages.

摘要： In a V-type engine with two bore-offset banks opposed to one another at a predetermined angle, an accessory mechanism is provided between the two banks. A drive belt for the accessory mechanism is disposed on the side of one of the banks which is recessed inwardly due to the bore offset. In another embodiment, the accessory mechanism is a supercharger driven by a balancing shaft which, in turn, is driven by the crank shaft. In yet another embodiment, the V-type engine has a separate timing belt for each bank, that is, a first timing belt for the bank which is recessed inward because of the bore offset, and a second timing belt for the bank which juts out because of the bore offset. A drive belt is provided for driving the supercharger. The belts are arranged in the following order from the inside outward: the second timing belt, the first timing belt and the accessory belt.
