Fast idle carburetor system

摘要: A carburetor system has a fast idle cam to hold the throttle plate in position for facilitating engine operation during warm-up after starting. The is movable second permit move its low response bias. control thermally expansible material disposed chamber piston with positive force when heated. Two electrical heaters are heat-transfer relation material. One of connected power source first started and responsive switch operable above selected ambient temperature level connects other heater that accelerate heating undergoes change physical state rapid expansion heated comprise elements coefficient resistivity which display sharp increase at change-of-state temperature.
