Internal combustion engine having an elastic connecting duct

摘要

An internal combustion engine of a manually operated implement, having an elastic connecting duct between the engine and an air filter for vibration-decoupled bridging of a vibration gap between engine and the air filter. The elastic connecting duct has a first conduit for fuel/air mixture and a second conduit for largely fuel-free air. The first and second conduits are separate tubes having respective bores that are separated from one another over their entire lengths, the inlet of the engine is operatively connected to the air filter via the first conduit, and an air duct window of the engine is operatively connected to the air filter via the second conduit.
