摘要： A fuel injection type multiple cylinder engine unit includes an oil lubricating device including an oil tank and the oil in the oil tank is pumped up by a pump having an oil drain side to which pipes are connected for supplying the oil near the injectors. Each of the pipe has a front nozzle portion disposed at a portion near the front fuel jetting end of the injector and the fuel and the oil independently injected in an intake device of the engine unit are atomized and mixed with suitable mixture ratio. The intake device of the engine unit is provided with a surge tank which comprises a main surge tank formed integrally with an inlet manifold and sub-surge tanks formed by forming recesses between the respective adjacent intake pipes in association with the inlet manifold. The main surge tank and the sub-surge tanks are communicated with each other to thereby increase the total inner volume of the surge tank.

摘要： A crankshaft support structure comprises a crankshaft, a crankcase for supporting the crankshaft, a lubricant-sealed bearing interposed between the crankshaft and the crankcase. This structure enables the amount of a lubricant in combustion gas to be reduced and the structure of an engine to be simplified by avoiding the provision of a oil passage for suppling the bearing with a lubricant.

摘要： In a two cycle internal combustion engine (2), a fuel-air flow passage and reservoir (52) is provided along the exhaust bridge (34) and between the piston (4) and the cylinder inner wall (36) for lubricating the exhaust bridge (34). The piston (4) has a flat spot (50) machined on its side wall (38) to form an axially extending flow passage and reservoir closed at its top end by the piston rings (40) and at its bottom end by a lower portion (60) of the piston side wall (38) which is not machined and which is closely adjacent the cylinder inner wall (36). When the piston (4) is in its power stroke, crankcase pressure forces fuel-air mixture through holes (56, 58) in the piston side wall (38) at the flat surface (50) into the flow passage and reservoir (52). If the exhaust bridge (34) heats and expands into the cylinder (6), the piston (4) will not rub on it.
