ABSTRACT:
A portable engine has a fan cover fixed to a front surface of a crankcase to cover a fan and to guide upward a blown stream of air generated by the fan, and a cylinder cover disposed behind and in series with the fan cover to cover an engine cylinder and to guide the blown stream toward the engine cylinder. The portable engine has a partition plate formed integrally with said crankcase to cover a step formed between the fan cover and the cylinder cover, and an ignition coil is fixed to the partition plate. According to this arrangement, heat of the engine cylinder will not be directly transmitted to the ignition coil to cause deterioration of the function of the ignition coil. The engine cylinder has positioning pieces which are engaged with positioning holes formed on the crankcase to allow easy assembling and a correct positioning of the engine cylinder and the crankcase.
