Abstract

The present invention relates to an engine, in particular four-stroke engine, having at least two cylinders, which ignition timings differ from each other, and a stroke discriminating device for discriminating strokes of said at least two cylinders based upon a difference between intake pressures detected by intake pressure sensors for individually detecting intake pressures of said at least two cylinders.
