摘要:
In a forcedly air-cooled engine (1) a local high temperature portion (16) is adapted to be cooled effectively so that thermal distortion and thermal breakage of a cylinder (24) and/or a cylinder head (3) caused by such a local high temperature can be avoided. As the means for preventing thermal distortion, there is provided a cylinder jacket (17) for cooling part of its cylinder (24), provided in a partition wall (16) between the cylinder and its push rod chamber (18). As the means for preventing thermal distortion of the cylinder head (3), there is provided a cooling air passage (37) in a cylinder head (3) and a head jacket (33) for oil cooling around a divided combustion chamber (28) so as to circulate oil through the head jacket (33). Local high temperature portions of the cylinder and/or the cylinder head can thereby be effectively cooled.
摘要:
An overhead-valve type forcedly air-cooled engine has a cylinder jacket (17) for cooling part of its cylinder (24), provided in a partition wall (16) between the cylinder and its push rod chamber (18) in order to solve a problem such as thermal distortion of the cylinder. A portion of the lubricating oil delivered from an oil pump (10) in a forced lubrication system employed in the engine serves to cool only the partition wall (16) which forms part of the periphery of the cylinder (24) during passing through the cylinder jacket (17).
摘要:
A split-cycle engine includes: a first cylinder housing a first piston, wherein the first piston performs an intake stroke and a compression stroke, but does not perform an exhaust stroke; a second cylinder housing a second piston, wherein the second piston performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke; and a valve chamber housing a valve, the valve comprising an internal chamber that selectively fluidly couples to the first and second cylinders, wherein the valve and internal chamber move within the valve chamber and relative to the first and second cylinders.
