The invention discloses a pre-ignition chamber
fuel supply system and an engine with the pre-ignition chamber
fuel supply system. The pre-ignition chamber
fuel supply system comprises a pre-ignition chamber device and an air inlet device; the air inlet device is communicated with the pre-ignition chamber device; the pre-ignition chamber device is communicated with the engine; the air inlet device comprises an air inlet pipeline and a gasification mixing device used for gasifying and mixing
fuel oil and air flowing in from the air inlet pipeline; and the air inlet pipeline penetrates through the gasification mixing device to be communicated with the pre-ignition chamber device. The pre-ignition chamber adopts a pre-mixing mode, so that the
equivalence ratio of the ignition position of the pre-ignition chamber is easier to guarantee, the mixing quality is improved, and coking and
soot generation caused by too thick
mixed gas are avoided. The high-pressure
mixed gas is prepared when used, a high-pressure gas storage device is omitted, the temperature of the compressed
mixed gas is increased, and the ignition stability is further improved. After a
throttle valve is selected at the air inlet position, the preparation amount of the mixed gas may be in direct proportion to the load of the engine, and no or only a simple
electric control device is required.
