Title: Valve system of internal combustion engine
Inventor: MORI TAIICHI
IPC: F01L13/00
Filed: 1993-12-24
Abstract: PURPOSE:To discharge the air in a working oil channel by detecting the operating condition of an engine to transmit the condition to the oil pressure release mechanism of a valve system, and by setting the oil pressure release mechanism so that oil pressure is released for a specific period of time at the time of starting the engine. CONSTITUTION:An oil pressure driving mechanism 100 is interposed between a cam 1a and an engine valve 2. When a cam shaft 1 is rotated and driven, the engine valve 2 is opened/closed through the oil pressure driving mechanism 100. When an oil pressure release valve 20 is released to drain the oil in the oil pressure driving mechanism 100, a working oil chamber 12 is deprived of a transmission mechanism for continuing to open the engine valve 2, and the closing period of the engine valve 2 is changed to a quick closing side. A control means 40 has a circuit for carrying out the operation of changing closing period, and the oil pressure release valve 20 is opened for a specific period of time at the time of starting an engine by means of a signal of a driving condition detection means 50 while the air in an oil route is discharged from the oil pressure driving mechanism 100, by the control means 40. Delay in starting lifting of the engine valve at the time of starting the engine is thus inhibited, and degradation of starting performance is also prevented.
