Abstract
A lubrication system for a four cycle engine that lubricates the valve mechanism with the oil mist of the concentration, lowered by the liquefying means. The lubrication system has an oil feeding passage for connecting an oil reservoir with the crank chamber and sending the oil retained in liquid form in the oil reservoir to the crank chamber under a negative pressure of the crank chamber, a communication passage for connecting the crank chamber with the oil reservoir and sending oil mist generated in the crank chamber to the oil reservoir when under a positive pressure of the crank chamber, liquefying means in the oil reservoir for liquefying the oil mist sent from the communication passage to the oil reservoir to decrease the concentration of the oil mist, and a supply passage for supplying the oil mist from the oil reservoir to the valve operating chamber through the liquefying means.
