摘要： An engine comprises a first cylinder and a second cylinder adapted to perform explosions at such timing that an interval from the explosion in the first cylinder to the explosion in the second cylinder is shorter than an interval from the explosion in the second cylinder to the explosion in first cylinder, an intake manifold having an intake passage, and branch passages communicating the intake passage with the first and the second cylinders. The engine has at least one of the construction that an interval from the explosion in the second cylinder to the intake operation of the second cylinder is set longer than the interval from the explosion in the first cylinder to the intake operation of the first cylinder, and the construction that an interval in which intake and exhaust operations of the second cylinder are overlapped is set shorter than an interval in which intake and exhaust operations of the first cylinder are overlapped, so as to reduce misfire during low speed idling and to enable the engine to produce large output power during high load operation.
摘要翻译：发动机包括第一气缸和第二气缸，其适于在这样的定时进行爆炸，使得从第一气缸中的爆炸到第二气缸中的爆炸的间隔短于从第二气缸中的爆炸到爆炸的间隔第一气缸，具有进气通道的进气歧管和将进气通道与第一和第二气缸连通的分支通道。发动机具有以下结构中的至少一种：从第二气缸的爆炸到第二气缸的进气操作的间隔被设定为比从第一气缸的爆炸到第一气缸的进气操作的间隔更长，将第二气缸的进气和排气操作重叠的间隔设定为比第一气缸的进气和排气操作重叠的间隔短，从而减少低速怠速期间的失火并使发动机在高负载运行时产生大的输出功率。
