PURPOSE: To obtain a diesel engine fuel which can lower the environmental pollution while achieving resource saving by blending illuminating kerosine with fuel oil special A.

CONSTITUTION: This engine fuel mainly consists of a blend of illuminating kerosine with fuel oil special A in a weight ratio of about 2:1 to 1:3. To prevent the clogging of the fuel filter of an engine by sludge, etc., it is effective to remove impurities from the fuel oil with a filter or the like before or after the blending. When the fuel further contains additives such as a combustion accelerator and a water separating agent, it is more effective. This fuel can relieve the environmental pollution problem (low CO, low CH, low NOX, low SOX and low soot) while achieving resource saving (low fuel consumption and low CO2) which are the merits of a Diesel engine, contributes to improve the global environments, and can markedly alleviate injury to the health, damage by acidic rain, etc.
