At its off position the engineis throttled down and the spark retarded, so that it runs at sucha low speed that the generator loses its excitation. By movingthe lever from the off position, the engine speeds up, the e. m. the generator picks up and delivers sufficient current to startthe car. By opening the throttle still further, the engine speedis increased, the car speed thus being governed by the speedof the engine, and inversely the speed of the car will be reducedby throttling down the engine. The efficiency of the above gasoline-electric combination forthis class of service compares very favorably with any type of. Street A NEW GASOLINE-ELECTRIC BUS SEATING TWENTY PASSENGERS speed change gears, and, moreover, has the great advantagesof large variations of speed, flexible drive, ease of control,minimum wear and tear, the acceleration and changes of speedbeing smooth and without jar or shock, which are ever presentwith any mechanical change speed gear. The speed of thetwenty-passenger bus on good level macadam is 12 m. p. h.,and the engine has power enough to drive car up a 10 per centgrade. The economy of this outfit on good level macadam isbetween 15-ton and 20-ton-miles per gallon of gasoline. Theweight of the bus loaded with twenty passengers is approxi-mately tons.
