摘要： An engine comprising a first intake valve and a second intake valve that are arranged on each side of a plane including the axis of the cylinder of the engine. A first intake passage and a second intake passage are connected to the combustion chamber via the first intake valve and the second intake valve, respectively and extend along the plane in the same direction. A first fuel injector is arranged in the combustion chamber to inject fuel toward a region of the combustion chamber, which is located on the first intake valve side of the plane. A second fuel injector is arranged in the second intake passage to inject fuel into the second intake passage.

摘要： A direct fuel injection type spark ignition internal combustion engine includes a piston/cylinder structure including a deep dish portion, a peripheral portion, and a shallow dish portion. The peripheral portion has a depth smaller than the deep dish portion and greater than the shallow dish portion and a diameter larger than the deep dish portion and smaller than the shallow dish portion. At medium engine loads, fuel is injected toward an edge portion defined between the deep dish portion and the peripheral portion and is divided by the edge portion into two portions. One portion flows into the peripheral portion and is evaporated to generate a moderately rich air-fuel mixture which helps to propagate flame from the deep dish portion to the remaining portion of a combustion chamber including the shallow dish portion.

摘要： An internal combustion engine comprising a fuel injector for injecting fuel directly into a cylinder and a calculating device for calculating a calculated amount of fuel to be injected on the basis of an engine operating state. The fuel injector injects all of the calculated amount of fuel during a compression stroke when the calculated amount of fuel is smaller than a predetermined first amount of fuel, and injects a part of the calculated amount of fuel during an approximately first half of an intake stroke and injects a remaining part of the calculated amount of fuel during a compression stroke when the calculated amount of fuel is equal to or larger than a predetermined second amount of fuel which is larger than the predetermined first amount of fuel.
