To reduce the amount of exhausted unburned fuel and further improve fuel efficiency of an internal combustion engine 10 provided with an ignition device 12 that ignites fuel air mixture more forcefully than a spark discharge in a combustion chamber 20. The internal combustion engine 10 includes an internal combustion engine main body 11 formed with the combustion chamber 20 and the ignition device 12 that ignites the fuel air mixture more forcefully than the spark discharge in the combustion chamber 20. In addition, the internal combustion engine 10 includes an electromagnetic wave emission device 13 that emits an electromagnetic wave supplied from an electromagnetic wave oscillator 32 from an antenna 41. The electromagnetic wave emission device 13 emits the electromagnetic wave from the antenna 41, thereby creating an electric field for accelerating a propagation speed of a flame.

A droplet detection system includes a sensing channel, such as a microfluidic channel, configured to receive a flow of fluid that may contain one or more liquid droplets dispersed in the fluid. The cross-sectional area of the sensing channel maybe configured to allow droplets of a predetermined size to flow through the channel one at a time. A light source, a light aperture, and a light detector are positioned outside the sensing channel, which use light in a selected frequency band that has a substantially different absorbance for the liquid compared to the fluid. Liquid droplets may be detected and characterized using a signal from the light detector.

A purification system for purifying exhaust gas from an engine includes a separation part that separates oxygen and nitrogen contained in air, an ozone generation part that generates ozone from oxygen separated by the separation part, and a supply part that supplies ozone generated by the ozone generation part to an intake pipe and an exhaust pipe of the engine. The purification system includes a supply control device that adjusts an amount of ozone supplied to the intake pipe and an amount of ozone supplied to the exhaust pipe according to a purification rate of exhaust gas of the engine.
