Abstract
The utility model discloses a one-cylinder one-cover four-valve series diesel engine cylinder cover, which comprises valve seat ring holes, valve guide bar holes, valve rotary mechanism holes, oil sprayer liner holes, an air inlet channel, an exhaust channel, valve tappet holes, and cylinder cover outlet holes; four valve seat ring holes are arranged on the cylinder cover; two of the valve seat ring holes are inlet valve seat ring holes and two are exhaust valve seat ring holes. The one-cylinder one-cover four-valve series diesel engine cylinder cover has a novel and reasonable structure, canbe applicable to various four-valve diesel engines of one-cylinder one-cover four-valve series with stroke between 160 and 170mm, cylinder diameter between 138 and 142mm, and different cylinder quantities, can meet series product development and establishes a foundation for researching new diesel engines with high-output powers.
Description
Technical field:
The utility model relates to a kind of stroke 160～170mm, cylinder diameter 138～142mm one cylinder one lid four valves series cylinder cover for diesel engine.
Background technique:
Along with fast development of national economy, the requirement that marine diesel engine is energy-saving and cost-reducing, develop to high-power direction is more and more higher, existing double head two valve cylinder head, the output power of diesel engine constantly promotes on its basis, but be subject to two valve cylinder head valve circulation areas, the output power of diesel engine is near the limit.To develop for this reason that output power is bigger, the new architecture of energy-conserving and environment-protective more, better reliability, at first must design a kind of new cylinder lid, make it can adapt to the requirement that diesel engine power further improves.
Summary of the invention:
The purpose of this utility model is to provide an a kind of cylinder one lid four valves series cylinder cover for diesel engine that can adapt to stroke 160～170mm, cylinder diameter 138～142mm one cylinder one lid four valve serial diesel engines.
Technical solution of the present utility model is:
An a kind of cylinder one lid four valves series cylinder cover for diesel engine, comprise air valve seat ring hole, valve guide rod hole, valve rotating mechanism hole, oil sprayer bushing hole, intake duct, air outlet flue, valve tappet hole, cylinder head osculum, it is characterized in that: be furnished with four air valve seat ring holes on the cylinder head, two is the inlet valve seat ring hole, and two is the exhaust valve seat insert hole.
Air valve seat ring hole offset design.
Setover with the air valve seat ring hole in valve guide rod hole, valve rotating mechanism hole.
Cylinder head is provided with the oil sprayer bushing hole, and is provided with the oil sprayer bushing closure gasket groove.
Intake duct, air outlet flue are distributed in both sides, can arrange according to complete machine and select for use.
The valve tappet hole is in exhaust side.
Exhaust side is provided with the cylinder head osculum.
Cylinder head is provided with the lubricated rocker part of oil duct.
Cylinder head is provided with directed spray orifice cooling oil sprayer bushing.
Cylinder head is provided with lubricating oil return hole, two places.
Cylinder head is provided with water hole on the cooling water of many places.
The utility model novel and reasonable structure, the various four-valve diesel engines that can adapt to a cylinder one lid four valve serial diesel engines of stroke 160～170mm, cylinder diameter 138～142mm and difference cylinder number use, can satisfy series product development, for the development of new high-output power diesel engine is laid a good foundation.
