Class 7(3) Fuel is delivered through a non-return valve 9 to a storage space 2 on the piston suction stroke and forced therefrom by the compression pressure, acting through passage 3, through injection passage 4 into the throat of a passage 24 between the main and auxiliary combustion chambers 23, 24, a valve 8, Fig. 2, restricting or closing the passage 3 during the suction stroke. The storage space 2 contains a sliding piston valve 8, Fig. 2, controlling ports 6, 7. On the engine suction stroke piston 8 moves to the left to block the passage 3 and prevent fuel being drawn into the engine cylinder, and fuel flows from the supply 1 through non- return valve 9 into the cylinder 5. On the engine compression stroke piston 8 is forced to the right and drives the fuel through orifices 7, annular space 11 and orifices 6 into the air flowing through passage 3 into the injection passage 4. The stroke of piston 5 may be adjustable and the fuel supply is controlled by a throttle valve 28, Fig. 1. An engine-operated valve may be provided in passage 4 and the piston 8 may be provided with a small bleed orifice to allow a small amount of fuel to flow through passage 3 into the engine cylinder. In Fig. 3 the fuel storage space 41 is formed in a block 40 separate from the cylinder to reduce fuel vaporization. |
