Abstract: PURPOSE:To carry out favorable combustion over all load zones by making part of exhaust gas re-enter a combustion chamber while swirling around a cylinder axis and forming a squash area in between a cylinder wall face and the top of a piston. CONSTITUTION:New air ports 20 and exhaust ports 22 are oppositely provided on a cylinder head 14 and new air valves 24 and exhaust valves 26 are provided to these ports respectively. In this case, the exhaust port 22 on which one Es of the exhaust valves 26 is provided is formed at a right angle to the longitudi nal axis of an engine so as to form a straight line with the branch pipe 50a of an exhaust manifold while being opened in the tangential direction with respect to a combustion chamber 18. Thereby, a swirl S is formed around a cylinder axis by a re-entered exhaust gas. On the other hand, squash areas 58a are formed in between the inner wall of the cylinder head 14, i.e., the upper wall of the combustion chamber and a piston. Thereby, stratification can be properly disturbed while properly mixing a small quantity of remaining exhaust gas with new air.

Abstract: PURPOSE:To stratify fresh air and exhaust gas, so as to improve the ignitionability, by setting an exhaust system adapted to control the pressure fluctuation of back pressure of an exhaust port in light load range of an engine, and setting a driving mechanism or others, adapted to open an exhaust valve earlier than one of intake valves, and close this exhaust valve later than the other suction valve. CONSTITUTION:In light load range of an engine, an intake air control valve 16 is closed, and on the other hand, an exhaust gas control valve 34 is opened. Then, exhaust valves 31a, 31b are opened according to the descendent motion of a piston 3, to blow the exhaust gas toward exhaust ports 32a, 32b, respectively, and this exhaust gas is blown back to a combustion chamber 2. At this time, a swirl of exhaust gas is formed by the eccentric port 32b and a mask 5. On the other hand, fresh air passed through a throttle valve 13 and a supercharger 14, is led slowly into the combustion chamber 2 through the first suction valve 21a which opens later than the second intake valve 21b, and gathered near a sparking plug 4 on the cylinder head 6 side. In this way, the fresh air on the cylinder head 6 side and the exhaust gas on the piston 3 side, are stratified, and consequently, the ignitionability is improved.

Abstract: PURPOSE:To improve the ignitability by providing a valve for controlling an exhaust system to generate supercharging effect produced by an exhaust pulse between cylinders, a driving mechanism for opening an exhaust valve earlier than an intake valve and a swirling means for the exhaust or the like, and thereby stratifying fresh air and the exhaust. CONSTITUTION:In the light loading range of an engine, an intake control valve 16 is closed, and an exhaust control valve 34 is opened. As each of exhaust valves 31a, 31b is opened during the downward stroke of a piston, high temperature exhaust blown down into each of exhaust ports 32a, 32b is flowed backward to a combustion chamber 2. At this time, an eccentric port 32b and a mask 5 generate an exhaust swirl. In addition to that, when the lifting quantity of an intake valve 21a has increased, the fresh air having passed through a throttle valve 13 and a supercharger 14 is introduced into the combustion chamber 2 from an inlet port 20a through the intake valve 21a. Therefore, the fresh air is slowly introduced on the exhaust swirl to be collected near an ignition plug 4 on the side of a cylinder head, and thereby the fresh air on said side and the exhaust on the side of the piston are stratified respectively.

Abstract: PURPOSE:To make the promotion of lightweightness attainable as well as to improve productivity ever so high, by forming a plastic mode in advance, while casting a crankshaft bearing cap part by means of a full-mold foundry. CONSTITUTION:Each crankshaft bearing cap part is first formed with a plastic model 10. At this stage, each plastic model 10 is easily formable into complex form without any consideration of a die releasing direction. Therefore, this plastic model is easily formable into such a fog form as abstracting unnecessary thickness while keeping the strength required. This plastic model is replaced with a metal by means of a full-mold process so that the crankshaft bearing cap part 12 replaced with a substitution metal is unnecessary to consider a split mold in time of casting, thus productivity is raised so high and, what is more, it is formable into an optimum light weight structure. Since a horizontal beam 11 is also formed with a separate single part in advance, geometrical form machining is made performable, thereby constituting to improvements in the promotion of lightweightness and productivity.

Abstract: PROBLEM TO BE SOLVED: To provide an oil jetting pump for an internal combustion engine, using oil jet for sufficiently cooling a piston by increasing the flow rate of oil without heightening the capacity of an existing oil pump.
SOLUTION: The oil jetting pump for the internal combustion engine sucks oil from a main oil hole of the internal combustion engine having the piston to be cooled by oil jet and forcibly feeds the sucked oil to an oil jetting oil hole. It comprises a counter weight 40 for a crankshaft having an outer periphery face set into a cam shape, a plunger 22 to be reciprocated with a roller at one end for slide contact with the counter weight, and a thermo-waxed slider 24 provided in the plunger for closing a top portion of the plunger to allow the forcible feed of the oil when the oil has a certain temperature or higher.
