要約
(EN)
An air scavenging-type two-cycle engine where a bearing of a crankshaft can be lubricated with gas blow-by being controlled by a simple structure. The engine has a first scavenging passage (13) communicating between a combustion chamber (1a) and a crank chamber (2a) through a bearing (81) of a crankshaft (8), a second scavenging passage (14) directly communicating between the combustion chamber (1a) and the crank chamber (2a), a suction chamber (72) formed in a side face of a piston (7), a mixture gas passage (10) through which a mixture gas (M) is sucked into the suction chamber (72), and an air passage (11) through which air (A) is introduced into the crank chamber (2a). In a suction stroke, the mixture gas (M) from the mixture gas passage (10) is introduced into the first scavenging passage (13) through the suction chamber (72), and the air (A) from the air passage (11) is introduced into the crank chamber (2a). In a scavenging stroke, before the mixture gas (M) in the first scavenging passage (13) is introduced into the combustion chamber (1a), introduction of the air (A) in the crank chamber (2a) into the combustion chamber (1a) through the second scavenging passage (14) starts.
(FR)
L'invention concerne un moteur à deux cycles de type à balayage d'air dans lequel un vilebrequin peut être lubrifié par un gaz perdu commandé par une simple structure. Le moteur comporte un premier passage de balayage (13) communicant entre une chambre de combustion (1a) et un carter (2a) à travers un roulement (81) d'un vilebrequin (8), un second passage de balayage (14)communicant directement entre la chambre de combustion (1a) et le carter (2a), une chambre d'aspiration (72) formée dans une face latérale d'un piston (7), un passage de gaz mélangé (10) par lequel est aspiré le gaz mélangé (M) dans la chambre d'aspiration (72), et un passage d'air (11) par lequel l'air (A) est introduit dans le carter (2a). Dans un temps d'aspiration, le gaz mélangé (M) provenant du passage (10) de gaz mélangé est introduit dans le premier passage de balayage (13) à travers la chambre d'aspiration (72), et l'air (A) provenant du passage d'air (11) est introduit dans le carter (2a). Dans un temps de balayage, avant que le gaz mélangé (M) arrive dans le premier passage de balayage (13) et soit introduit dans la chambre de combustion (1a), débute l'introduction d'air (A) dans le carter (2a) puis dans la chambre de combustion (1a) par le second passage de balayage (14).
