Definitions

  • the independent adjustment described of the throttle lift within the free distance between the stops 112 and 113 controls the fuel-air mixture correctly according to loading, speed and operating condition of the engine.
  • This correct lfuel-air ratio is achieved with the accelerator lever in any position. It fluctuates between the stoichiometric ratio and operation with a slight excess of air and is the necessary condition for complete combustion of the gas mixture in the cylinders, the exhaust gas of which only contains traces of poisonous carbon monoxide gas, which are far below the allowed limit.
  • a carburettor according to claim 4 characterised in that the levers (100, 107) holding the spring (105) are mounted in such a way that the spring tension to a gradually decreasing extent when they pivot to open the throttle member (10).
