Abstract
A supply system for supplying ozone to an engine includes an electrolysis part that electrolyzes water to generate hydrogen and oxygen, a first supply part that supplies hydrogen generated by the electrolysis part to an intake pipe of the engine, an ozone generation part that generates ozone from oxygen generated by the electrolysis part, and a second supply part that supplies ozone generated by the ozone generation part to the intake pipe.
Claims7
A supply system for supplying ozone to an engine, comprising:
- an electrolyzer that electrolyzes water to generate hydrogen and oxygen;
- a first supplier that supplies the hydrogen generated by the electrolyzer to an intake pipe of the engine;
- an ozone generator that generates ozone from the oxygen generated by the electrolyzer;
- and
- a second supplier that supplies the ozone generated by the ozone generator to the intake pipe;
- and
- a processor that executes a supply control program to supply the hydrogen to the intake pipe when an exhaust gas temperature of the engine is lower than a predetermined value, and does not supply the hydrogen to the intake pipe when the exhaust gas temperature of the engine is equal to or higher than the predetermined value,
- wherein the predetermined value is a reaction temperature at which at least any of i) nitrogen oxides and unburned fuel and ii) nitrogen oxides and ammonia start to react on a catalyst of a purification device provided in an exhaust pipe of the engine.
