摘要:
A valve-operating mechanism (48) for an internal combustion engine (10) having intake and exhaust valves (43, 46) and valve control members (82, 92) for controlling the intake and exhaust valves. The intake and exhaust valves are configured as dual valves having an outer valve (54, 65) and an inner valve (55, 66). The valve control members, at least during scavenging, simultaneously close the outer valves of the intake and exhaust valves, producing a non-overlapping state, and simultaneously open the inner valves of the intake and exhaust valves, producing an overlapping state.
摘要:
Cooling control device for a condenser is provided which includes the condenser (13), a cooling device for cooling the condenser, and a control device for controlling the cooling device. The cooling device includes a first cooling fan (46) for cooling a gaseous-phase portion (70) of the condenser, and two second cooling fans (47, 48) for cooling a liquid-phase portion (71) of the condenser independently of the first cooling fan. The control device also includes a pressure control section (62) for optimally adjusting a pressure within the gaseous-phase portion, and a temperature control section (64) for optimally adjusting a temperature within the liquid-phase portion. The pressure control section operates the first cooling fan, in accordance with a detected pressure within the gaseous-phase portion, to adjust the pressure within the gaseous-phase portion. The temperature control section operates the second cooling fans, in accordance with a detected temperature within the liquid-phase portion, to adjust the temperature within the liquid-phase portion.
