PURPOSE:To enable cold start of an engine to be made readily even in extremely cold districts and also improve the thermal efficiency thereof by an arrangement wherein a high pressure and high temperature environment is formed in a pressure accumulator so as to quickly evaporate and divide fuel particles finely. CONSTITUTION:A premixing chamber 1 has an inlet pipe 3 for air A connected to one side wall thereof through a check valve 3a adapted to open on the side of the chamber 1. The chamber 1 has also an outlet pipe 4 for mixture of the air A and the initial fuel particles F connected to the upper part of the other side wall thereof. A pressure intensifying chamber 12 on one side is allowed to communicate through a check valve 14 with a pressure accumulating chamber 13, whilst the pressure intensifying chamber 12' on the other side is allowed to communicate through a check valve 14' with a pressure accumulating chamber 13'. The arrangement is made such that the pressure intensifier is operated to repeat suction, compression and delivery strokes the form a high pressure and high temperature environment or region in which fuel particles are allowed to quickly evaporate and divide finely, and the resultant fine fuel particles are supplied under pressure into a reformed gas producer 30 where they are changed into a reformed gas which is injected into an engine E. |
