PURPOSE:To enable to ignite an internal combustion engine like a diesel engine of the type ejecting liquid fuel into a combustion chamber efficiently at the time of starting, by employing such an arrangement that light beams are focused at least at two points in sprayed fuel. CONSTITUTION:Fine particles of fuel are ejected with vibration from a means 15 for feeding fine particles of fuel by passing current from an electric control means 22, such that the fine particles of fuel reach the focal points f1, f2, f3 and so on of light beams continuously or at the time when ignition is to be caused. Here, since the fine particles of fuel travel in the space of a combustion chamber 3, the greater the number of the focal points, the higher the probability of the fine particles of fuel passing through the focal points, so that fuel can be ignited in a reliable manner. Thus, fuel can be ignited effectively. |
