゛うことができるものである。。For this reason, the present invention has taken the following technical measures. That is, the rotation area of the camshaft (1) is located at the bottom of the pump chamber (3) that operates the lower camshaft (1) and the upper embroider injection pump (2) driven by the camshaft (1). An oil reservoir (4) for storing oil is provided in the pump chamber (3).
The engine fuel injection bong chamber is provided with an injection hole (7) on the upper side of the cylinder body (5) which communicates with the oil gear assembly (6) and injects oil toward the outer periphery of the fuel injection pump (2). With this configuration, the present invention has the following technical effects. Namely,
When the engine is rotating, the rotation of the camshaft (1) drives the fuel injection pump (2) and injects the oil into each cylinder.
The oil sent through the jet is ejected from the jet hole (7), and is poured around the outer circumference of the fuel injection pump (2) to generate heat generated by the fuel injection pump (2). While cooling, pour the oil directly into the oil reservoir (4) and add this oil to the 4Y1/' A? Since the camshaft (1) is close to the oil in (4) and the rotation is 11V, this camshaft (1) is used for nν1 slipping, and the 11'G configuration is simplified. , it is possible to carry out four-fold cooling of the fuel injection pump (2) without requiring special cooling parts L:+7. .
