Title:
【発明の名称】低圧クランクケース付2サイクル機関用燃料噴射制御装置
Document Type and Number:
Japanese Patent JPH03504749
Kind Code:
A
Abstract:
A two cycle internal combustion engine is provided with a fuel system including a low pressure fuel pump (204) and solenoid valve (206) supplying and metering fuel to the engine crankcase through a fuel line, without a carburetor, without a high pressure fuel pump, without high pressure fuel injectors, and without a constant fuel pressure regulator. The system senses the amount of combustion air supplied to the engine, and senses fuel flow velocity using a restriction orifice in the fuel line producing a fuel pressure drop indicating fuel flow velocity. A conduit is connected between the crankcase at a transfer passage and the fuel line downstream of the restriction orifice and passes warm presurized air-fuel mixture from the crankcase through the transfer passage to the fuel line to improve fuel atomization.
