Abstract: A fuel injection device comprises an air valve located upstream of an operator actuated throttle in the air intake passage. The air valve is actuated by airflow through the passage and opens in proportion to the increase in the flow rate of air. Fuel under pressure is delivered to the air passage through an electrically energized injector valve.

During cranking, the metering system delivers a continuous energization signal to the valve for maintaining it permanently open. The pressure of the fuel delivered to the valve is substantially decreased during cranking, i.e. as long as a continuous energization signal is delivered to the injector valve.

Abstract: The Toroid Sweep Engine with Reciprocating Jut generates power within a toroidal-shaped chamber whose walls are divided into two ring-like sections which are free to rotate relative to one another around the toroid axis. An obstacle juts from each of the wall sections into the chamber. Fresh air is pumped at high pressure and high temperature into a region of the chamber between the two obstacles, and fuel is then injected into and burned in this region. The products of combustion force the obstacles apart, turning a wall section, and when the obstacles eventually meet after circumnavigation of the toroid, one of them withdraws from the chamber allowing the obstacles to pass. More fresh air and fuel are introduced between the again separating obstacles following the rendezvous, while spent gases from the previous burning are swept and squeezed out an exhaust duct leading from that volume within the chamber which is compressed between the obstacles.
