Claims

[Scope of utility model registration request]

An annularly extending oil supply passage is provided inside the piston, and an oil supply port is opened on the circumference on the outer surface of the piston,
The oil supply port and the oil supply passage are communicated with each other by an oil passage, and an oil supply port is provided at the bottom of the oil supply passage, and the cylinder block is provided with oil toward the oil supply port. An oil nozzle for injecting oil is provided, and the oil nozzle and the engine's oil gear are connected by an oil supply pipe, and an on-off valve for opening and closing the oil supply pipe is arranged in the middle of the oil supply pipe. The engine is equipped with a temperature sensor that detects the temperature of the engine and outputs a signal, and the opening/closing valve can be controlled by a control device based on the output signal of the temperature sensor. , the control device issues a command to the on-off valve to open the oil supply pipe when the temperature of the engine is lower than a predetermined value, and issues a command to the on-off valve when the temperature of the engine is above a predetermined value. In the cylinder bore lubricating device for an engine, the oil supply pipe passes through an exhaust passage of the engine, and when the opening/closing valve is open, the oil supply pipe passes through an exhaust passage of the engine. A cylinder bore lubricating device for an engine, comprising an exhaust gas control device that applies exhaust gas to an oil supply pipe and prevents exhaust gas from applying to the oil supply pipe when the on-off valve is closed.
