A two-stroke cycle engine for introducing a air/fuel mixture and an air from a scavenging passage into a combustion chamber includes a valve body for adjusting the opening of an air supply passage, through which the air is supplied to the scavenging passage, and a second opening of a air/fuel mixture supply passage, through which the air/fuel mixture is supplied to the scavenging passage, a check valve for preventing the air within the air supply passage from flowing in a reverse direction, and a delay member projecting into the air supply passage on an upstream side of the check valve for delaying the timing at which the air reaches from the valve body to the air scavenging passage.

A lubricating device for an overhead valve engine having a rocker arm chamber provided with a valve gear, a crank chamber provided with a valve driving gear, and valve drive push rods disposed between the valve gear and the valve driving gear. Provided are paths respectively communicating aforesaid crank chamber to aforesaid rocker arm chamber, aforesaid rocker arm chamber to aforesaid push rod chamber, and the bottom of aforesaid push rod chamber to aforesaid crank chamber through a bearing portion on a power takeoff side, or the bottom of aforesaid push rod chamber is communicated to aforesaid bearing portion of aforesaid power takeoff side with an outlet for breather gas in aforesaid push rod chamber.

An improved exhaust system for water craft engines is disclosed, which consists in the main an exhaust manifold connected to the cylinder exhaust port of the engine, an exhaust pipe joined at one end to the exhaust manifold and a diffuser connected at one end to the other end of the exhaust pipe and at the other end to the rest of the exhaust system including a muffler and steam separator. The exhaust pipe is divided into two axial parts, the first vertical, largely U-shaped pipe portion for direct connection to the exhaust pipe at downstream thereof and the second horizontal pipe portion for connection at one end thereof to the first pipe portion at downstream thereof and at the opposite end to the diffuser. The second pipe portion is disposed to extend adjacent to the exhaust manifold and made integral therewith in a rigid assembly, with the first pipe portion being releasably secured to the exhasut manifold and second portion through bolts for easy disassembly in servicing. Thus, since the exhaust pipe is integrally attached to the exhaust manifold through its divided first pipe portion, the entire exhaust system is held in relatively firmly fixed position in the engine compartment of rather limited space, so that operations to secure the various devices of the exhaust system there are greatly eased.
