摘要： A two-stroke engine has a cylinder wherein a piston is journalled for reciprocating movement. The piston delimits a combustion chamber configured in the cylinder. The engine has an outlet from the combustion chamber and a transfer channel which opens at an inlet opening into the crankcase and at a transfer window in the combustion chamber. The piston drives a crankshaft via a connecting rod. The crankshaft is rotatably journalled in the crankcase. At least one control element for the inlet opening is connected to the crankshaft so as to rotate therewith.The control element is so arranged that the inlet opening is at least partially closed thereby in at least one operating state of the engine during the downward stroke of the piston at least 5° crankshaft angle after the opening of the transfer window.

摘要： A two stroke engine comprises a cylinder, in which a combustion chamber bounded by a piston is formed, and an intake passage. A carburetor forms a section of the intake passage, within which a throttle element is mounted pivotably, and at least one main fuel opening and at least one idling fuel opening open into the intake passage, which is divided downstream of the carburetor into an air passage and a mixture passage. The idling fuel opening feeds a secondary passage arranged within the mixture passage. In the idling position, the throttle element may be arranged adjacent to the upstream entry opening in the secondary passage, and the throttle element may have an opening which, in the idling position of the throttle element, is arranged in the region of the entry opening and connects the secondary passage to that region of the intake passage located upstream of the throttle element.

摘要： Object It is intended to prevent intrusion of air-fuel mixture into an air cleaner by blow-back in an air-fuel mixture passage of a stratified-scavenging two-stroke engine.Solution The air cleaner (24) includes a guide member (30). A blow-back flow of air (20) flowing back to the air cleaner (24) through a first air opening (23A) due to blow-back of air is induced to a vicinity of a second air opening (23M) by the guide member (30). A blow-back flow of air-fuel mixture (21) occurring in an air-fuel mixture passage (2) prior to the blow-back phenomenon in an air passage (3) collides the air flow 20 moving toward the vicinity of the second air opening (23M), and retains the air-fuel mixture near the second air opening (23M).

摘要： A cylinder bore (4) of a two-stroke internal combustion engine (1) has first scavenging ports (12) and second scavenging ports (13) inside. The first scavenging ports (12) are nearer to an exhaust port (11) of the engine (1) than the second scavenging ports (13). In each scavenging stroke, the second scavenging ports (13) are opened earlier than the first scavenging ports (12) and introduce fuel-free air (A) from the second scavenging ports (13) into a combustion chamber (6). The first scavenging ports (12) are opened later and introduce an air-fuel mixture (M) pre-compressed in a crank chamber (8) into the same combustion chamber (6). Thus, harmful substances contained in exhaust gas discharged from the engine (1) are reduced.
