PURPOSE:To improve the combustion by mixing a gas into a fuel, and introducing the air into an injection pump to generate air bubbles in the atomized air of the injection nozzle, in a method of supplying a fuel to a Diesel engine through an injection nozzle. CONSTITUTION:Air is injected from an air inlet pipe 7 into a fuel leaving a feed pump 2. Since the mixing of air bubbles with the fuel is not sufficient, the fuel is agitated by means of a mixer 6, and a large number of pulverized air bubbles are uniformly distributed. Thus, the fuel is introduced into an injection pump 3 in this state. Since the injection pump 3 compresses the fuel at a high pressure of 200atm. or more, air bubbles are dissolved or pulverized and turned substantially into a liquid state. When this high pressure fuel is injected into a combustion chamber 5 from an injection nozzle 4, dissolved air is converted into air bubbles generated from the inner part of the atomized air. The atomized air is further mixed, and liquid drops are broken and further pulverized. Accordingly, the combustion is improved and fuel cost is decreased. |
