摘要： A V-type 8-cylinder four cycle internal combustion engine has a bank angle of 90 deg. and employs a double link type piston-crank mechanism for transmitting the force of each piston to a crankshaft. The double link type piston-crank mechanism comprises an upper link that has one end pivotally connected to the piston, a lower link that is rotatably supported by a crank pin of the crankshaft and has one end pivotally connected to the other end of the upper link, and a control link that has one end pivotally connected to the other end of the lower link and the other end pivotally connected to a cylinder block. Preferably, the crankshaft is of a single plane type in which all of the four throws are in a common plane.

摘要： An internal combustion engine control apparatus is provided with a hydraulically operated variable valve operating mechanism for varying the valve timing of air intake valves, and a water temperature sensor for sensing engine coolant temperature to estimate the degree of engine warm-up. The valve operating mechanism is controlled to switch the valve timing from the warm-up idle valve timing with a high idling speed to the post-warm-up idle valve timing with a slower idling speed as the engine temperature approaches the warm-up temperature threshold. The switch in valve timings starts before an engine rotational speed falls below a rotational speed threshold lying between the high idling speed during the warm-up idling and the post-warm-up idling speed during the post-warm-up idling such that a sufficient hydraulic pressure switch the valve timing with a specific degree of responsiveness is attained when the engine rotational speed is at or above the rotational speed threshold.
