とくに小形内熱機関にとっては不利に作用する。Lubricants are used in internal combustion engines in addition to lubrication! Its role is to transport sS heat away from moving parts and combustion heat from highly loaded parts. The amount of heat absorbed by these lubricants must be transferred to the atmosphere. This is generally carried out by an air-cooled lubricant cooler or through the walls of the engine body or lubricant container [to the wind during the run or to the cooling water through a heat exchanger. The use of a separate lubricant cooler requires an increase in overall dimensions, which is particularly disadvantageous for small internal heat engines.

にも潤滑剤が冷却されることは不利に作用する。The lubricant flowing back from the valve drive section passes through the return line, bypassing the dry oil sump, and returns directly to the lubricant storage container attached to the side of the engine body. The return line in the cylinder head is provided in the area of the cooling line through which the coolant passes and is returned from the cylinder head I4? #
This is to ensure that the agent is cooled. Therefore i+1
No need for separate coolers. This lubricant cooling within the cylinder head is not sufficient for air-cooled internal combustion engines. This is because an air-cooled type cannot achieve as strong cooling as a liquid-cooled type. It is also disadvantageous that the lubricant is cooled, for example when rotating carrots to warm them or during winter operation when the lubricant's working temperature K has not yet been reached.

By installing a valve in the return line? ! 4? The supply of lubricant to the line can be interrupted, allowing lubricant to enter the oil pan directly through the overflow port. The valve can be controlled manually or automatically. If a thermally actuated valve is used, the supply or shutoff to the cooling line takes place automatically depending on the operating temperature of the lubricant. The conduit in the cylinder and the return conduit in the cylinder head can be cast together at the same time or drilled together during machining of the buckle holes, so that additional working steps are omitted.
