Abstract
A two-stroke engine includes an ignition module that receives a detection signal from a magnetic sensor for detecting a permanent magnet and transmits an ignition signal to an ignition plug. The permanent magnet is provided at a single position on a flange that rotates synchronously with the magnetic sensor. The magnetic sensor is attached to one of sensor attachments and provided at two positions adjacent to the engine body. The sensor attachments and are so provided as to correspond to a rotational direction of the engine. With such an arrangement, the permanent magnet is less affected by noise because the permanent magnet is disposed at only one position. By changing a position at which the sensor is attached, the engine having common components is enabled to work in the same manner during both of normal rotation and reverse rotation.
