1. An improved rotary engine having a rotor having N lobes, an intake port an exhaust port, a housing with respect to which the rotor is mounted for rotational motion relative to the housing, the housing having N+1 lobe-receiving regions configured to successively receive the lobes as the rotor rotates relative to the housing, the housing having (i) a pair of sides axially disposed on first and second sides of the rotor, and (ii) a peak disposed between each pair of adjacent lobe-receiving regions, wherein the housing is further configured in relation to the rotor so as to establish a chamber associated with each one of the lobe-receiving regions, wherein a plurality of the chambers are configured to handle, in succession, intake, compression, combustion, expansion, and exhaust phases, wherein the improvement comprises: a conduit through the rotor, and a single fuel source configured to supply fuel to at least two of the plurality of chambers through the conduit in the rotor. 2. An engine according to claim 1, further comprising a removably attachable cartridge containing one of fuel, a mixture of fuel and oil, and a mixture of fuel and fuel additives, in communication with the single fuel source. 3. An engine according to claim 1, wherein the single fuel source includes an injector disposed in the rotor and coupled to the conduit. 4. An engine according to claim 1, wherein the conduit is coupled to the intake port, and the single fuel source includes a carburetor, coupled to the conduit, supplying an air-fuel mixture to the conduit. 5. An engine according to claim 1, wherein the chambers are configured so that chamber volume at the end of the expansion phase is larger than the chamber volume at the start of the compression phase. 6. An engine according to claim 1, wherein the chambers are configured so that the chamber pressure at the end of the expansion phase is approximately 1 atmosphere. 7. An engine according to claim 1, wherein the engine comprises counterweights configured to balance the rotor. 8. An improved rotary engine having a rotor having N lobes, an intake port, an exhaust port, a housing with respect to which the rotor is mounted for rotational motion relative to the housing, the housing having N+1 lobe-receiving regions configured to successively receive the lobes as the rotor rotates relative to the housing, the housing having (i) a pair of sides axially disposed on first and second sides of the rotor, and (ii) a peak disposed between each pair of adjacent lobe-receiving regions, wherein the housing is further configured in relation to the rotor so as to establish a chamber associated with each one of the lobe-receiving regions, wherein a plurality of the chambers are configured to handle, in succession, intake, compression, combustion, expansion, and exhaust phases, wherein the improvement comprises: conduits disposed in the peak; anda single fuel source coupled to the conduits through which is supplied an air-fuel mixture to two adjacent chambers. 9. A rotary engine according to claim 8, wherein the single fuel source includes a carburetor.
