Abstract
A stroke characteristic variable engine comprising a primary link connected to a piston which is slidably fitted in a cylinder, a secondary link connecting the primary link with a crankshaft and a tertiary link connected to the primary link or the secondary link at one end and to an engine main body via a control shaft at the other end thereof. An oil level position of engine oil stored in an oil pan is set such that at least part of the control shaft is submerged in the engine oil, whereby since oil stored within the oil pan can be used as it is, the lubrication around the control shaft can be ensured in a simplified configuration.
