The hydraulic valve rest mechanism is operated with an oil pressure that is controlled by a hydraulic control device so as to close and rest engine valves of a plurality of cylinders for bringing the cylinders into a rest state Therefore, the miniaturization of the multi-cylinder internal combustion engine along an axis of a crankshaft and can shorten a length of an oil passage which connects a hydraulic valve rest mechanism and a hydraulic control device. A hydraulic control device is arranged on an engine body directly above a portion thereof corresponding to a cylinder that is expected to assume a cylinder rest state.

Abstract: The present invention provides methods to take advantage of the exhaust gas pulses in an exhaust system of a multi-cylinder internal combustion engine to increase the volumetric efficiency over the complete operating range of the engine. It solves the problems of other systems which are only able to gain a beneficial effect from the exhaust gas pulses over a limited range of the engine operating speeds, by providing a means of varying the exhaust pipe lengths, combinations, and cross-sectional area of the exhaust passages of the multi-cylinder internal combustion engine. By this means it provides an exhaust system in which the exhaust gas pulse frequencies can be varied over the entire operating range of the engine to obtain desirable pulse frequencies matching the cylinder exhaust timing for efficient extraction of the exhaust gases, improvement in volumetric efficiency and a higher maximum engine speed. The various methods can be controlled by sensors connected to any or all of the engine rpm sensor, the gear change mechanism and the throttle valve. The methods are suitable for any type of multi-cylinder internal combustion engine, that is, in-line cylinders, horizontal opposed cylinders, V cylinder arrangement etc. and for any type of application whether stationary or on a moving vehicle. The methods solve the problem of other methods related to positioning on a motor cycle by being able to have the exhaust pipe combination change valve located between the engine cylinder exhaust outlet and later junctions of the exhaust pipes. Also the layout of the system is such that the components can be simply protected from damage and easily accessed for maintenance.

Abstract: An intake system for an internal combustion engine includes a variable length intake tract having a moveable intake pipe which selectively abuts a fixed intake pipe. During high speed operation, the moveable intake pipe is separated from the fixed intake pipe to provide a relatively short intake pipe length while in low speed operation, the moveable intake pipe abuts the fixed intake pipe so that a longer intake tract is formed. The influence of positive pressure waves on the air/fuel ratio during low speed operation is reduced by air flow resistance control means which increases the resistance of the intake system during low speed operation. This may be accomplished by use of an induction housing having a high speed chamber receiving the outlet of the fixed intake pipe and a low speed chamber receiving the outlet of the intake system when in the low speed intake mode, the low speed chamber having an intake opening having a higher air flow resistance than that of the opening of the high speed chamber. The intake system when used in a multi-cylinder engine may drive the moveable intake pipes of differing cylinders so that the transient shifting of the moveable intake pipe between the low speed mode and the high speed mode occurs at slightly different times for differing cylinders reducing the power droppage at any instant in time for the overall engine.

Abstract: A valve operating device for internal combustion engine which includes a cam shaft rotated by a crankshaft and a rocker arm which follows the cam of the cam shaft to open and close an intake or exhaust valve of the engine. Oil-pressure-operated control is provided for suspending the operation of the intake or exhaust valve according to the operating conditions of the engine. For this purpose, a cam shaft passage is formed in an oil pressure supplying passage which extends from an oil pressure source through an oil passage in the rocker shaft to the control mechanism in such a manner that the cam shaft passage extends through one end portion of the cam shaft. A changeover valve for opening and closing the cam shaft passage is provided at the one end portion of the cam shaft. A centrifugal governor provided at the one end portion of the cam shaft rotates with the cam shaft and turns the changeover valve when the speed of the cam shaft is in a predetermined range, thereby to communicate the oil pressure source with the control mechanism.
