Zusammenfassung:	To accurately detect suction pressure of a single cylinder engine.SOLUTION: A crank angle sensor 7 detects a crank angle of a single cylinder engine. A suction pressure sensor 44 is provided in a suction passage of the single cylinder engine, and detects suction pressure. A sampling unit 63 samples the suction pressure detected by the suction pressure sensor. A CPU 60 extracts M pieces of relatively small suction pressure out of N pieces of sampled suction pressure, and calculates bottom pressure from P pieces of residual suction pressure excluding some of the M pieces of suction pressure.SELECTED DRAWING: Figure 2 【課題】単気筒エンジンの吸気圧を精度よく検知すること。【解決手段】クランク角センサ７は単気筒エンジンのクランク角を検知する。吸気圧センサ４４は単気筒エンジンの吸気経路に設けられ、吸気圧を検知する。サンプリング部６３は吸気圧センサにより検知された吸気圧をサンプリングする。ＣＰＵ６０はサンプリングされたＮ個の吸気圧のうちで相対的に値の小さなＭ個の吸気圧を抽出し、Ｍ個の吸気圧のうちのいくつかを除外した残りのＰ個の吸気圧からボトム圧を演算する。【選択図】図２
