Abstract: PROBLEM TO BE SOLVED: To maintain the holding force of a gas spring independently of temperature by having the elastic force to be increased with a rise of the operating temperature, and increasing the pushing force necessary for opening a pressure control valve at the same degree. SOLUTION: A pressure control valve 33 is formed of a valve cross sectional surface capable of being cut and a valve element 37, to which the pre-stress is applied by a compression spring 35. The compression spring 35 is formed of a bimetal spring for generating the elastic force to be increased with a rise of the temperature of the gas inside of a cylinder 7. A piston ring 23 contacts with a lower channel side wall with the frictional force generated between the piston ring 23 and an inner wall of the cylinder 7, and the valve element applies the prestress to the valve cross sectional surface by the spring 35. A piston rod 13 is drawn form the cylinder 7 by the delivery movement. The pressure control valve 33 is opened with the generation of the pressure inside of a working chamber 17.  In a direction for pulling the piston rod, the piston ring 23 is moved so as to contact with an upper channel side wall with the frictional force of the inner wall of the cylinder.

Abstract: PROBLEM TO BE SOLVED: To control adverse effects on drivability, emission and fuel efficiency and to stabilize combustion status of an internal combustion engine adequately when a variable valve timing mechanism switches the valve overlap from large to small during a transitory period from low to high load. SOLUTION: When in a transitory status toward low load (indicated by 'Yes' in S180, S190) and in a transitory status where valve overlap is decreasing (indicated by 'Yes' in S200), fuel injection quantity increase coefficient eflkl in deceleration (S210) is calculated according to a three-dimensional map eflkl- map (0-60). This is a three-dimensional map having three parameters of an actual displacement angle evt, an engine speed ene, and a real load eklsm. Thereby, combustion can be stabilized by necessary and sufficient increase in fuel quantity which is suitable for an operation status of the engine, and deceleration shock can be prevented. Moreover, feeling of deceleration can be obtained because no more fuel is increased than required, and aggravation of emission and fuel efficiency is prevented.
