摘要： 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.

摘要： A four-stroke reciprocating piston internal combustion engine with an intake valve an exhaust valve and a valve drive assembly (18) driven by the crankshaft (4) for actuating the intake valve (8) and the exhaust valve (10). A mixture-preparation device (15) supplies an air/fuel-lubricant mixture to the crankcase, which together with the piston functions as a pump for the mixture charge. A valve drive assembly housing (19, 20, 21, 22) comprising one or more sections (19, 20, 21, 22) and the intake channel (16) is supplied with a connecting duct (17) communicating with the crankcase volume (12) either by being connected to the crankcase or the cylinder, or by being connected to the valve drive assembly housing (19, 20, 21, 22), which communicates with the crankcase volume (12), and the communication from the intake channel (16) to the crankcase volume is arranged through at least one valve.
