A rotary combustion engine having two fuel injection nozzles, both mounted in the rotor housing on the downstream side of a trochoid lobe junction in the region in which combustion takes place, with both nozzles discharging in a generally upstream direction and with a spark plug disposed adjacent to the upstream one of said nozzles.

Rotary engine with pilot and main fuel nozzles downstream of top center

A rotary engine having a pair of fuel injection nozzles disposed adjacent to and on opposite sides of a lobe junction of the rotor housing in the combustion region and a spark plug is disposed adjacent to the fuel nozzle which is disposed on the downstream side of said junction.

Rotary engine with a pilot fuel nozzle downstream of top center

A rotary combustion engine having grooves in the engine side walls for bleeding off unburnt hydrocarbon gases from the trailing end of each working chamber during the late portion of its expansion stroke, these gases being bled through side housing grooves into the space between oil and gas seals on the sides of the rotor from which space the unburnt gases are returned to a working chamber during the intake stroke of said chamber.

Rotary combustion engine with side housing by-pass passages

The improved fuel injection system is for a rotary internal combustion engine having a housing within which a rotor is disposed for planetary rotary motion and which defines with the housing a plurality of combustion chambers. The improved fuel injection systems has a positive displacement fuel pump, such as of the plunger and barrel type, which is connected to deliver fuel to a fuel nozzle located to emit fuel into the combustion chambers upon actuation of the plunger. An actuating means, such as multi-profile cam is supported for rotation at a speed proportionate to rotor speed and disposed to effect reciprocative movement of the plunger. An automatic means, such as a pressurized fluid servomotor mechanism, is provided to effect a shifting of the cam relative to the pump plunger to change the speed of actuation of the plunger in proportion to rotor speed so that the duration of fuel injection into the combustion chambers at rotor speeds below high speed occurs during substantially the same amount of angular displacement of the rotor and for the same quantity fuel injected per revolution of the rotor as at high speed.

Fuel injection system for rotary internal combustion engine

A rotary combustion engine having a fuel nozzle for discharging fuel into each working chamber just prior to combustion and in which means are provided for increasing the width of the spray angle of the fuel discharged by said nozzle as the quantity of fuel discharged by the nozzle into each working chamber is increased.

Stratified charge rotary engine with variable spray angle fuel nozzle

A rotary combustion engine having two fuel nozzles for discharging fuel into each engine working chamber with fuel being discharged from only one of the nozzles during low power operation of the engine and being discharged from both nozzles during high power operation of the engine.
