摘要： An internal combustion engine comprises a cylinder block having a plurality of main bearing bulkheads, and a skirt section. Each bearing bulkhead is formed with through-holes each of which as an upper end opening to the skirt section and a lower end opening to the bottom surface of the bearing bulkhead. The bearing bulkhead is formed at its bottom surface with a depression. Each of a plurality of bearing caps is installed to the bearing bulkhead in a manner to fit in the bearing bulkhead depression. Additionally, bolts are disposed respectively in the bearing bulkhead through-holes, each bolt having an upper end section located on the skirt section and a lower end section located in the hole formed in the bearing cap, thereby eliminating the need for excess structure on the bearing cap to sharply reduce the weight of the bearing cap.

摘要： A sampling pulse generator circuit for a stereo demodulator circuit of a sample and hold system is disclosed. The pulse generator circuit uses pilot signals of an FM stereo broadcast as an input and produces output sampling pulses, which are phase-synchronized to the stereo subcarrier but have a 180.degree. phase difference to each other. The pulse generator circuit comprises a phase lock loop circuit having a multiple number of frequency dividers arranged in cascade. Selected outputs of these frequency dividers are logically summed to produce the output sampling pulses with a predetermined and stable pulse width.

摘要： An inner shell having aligned first and second expansion chambers is spacedly disposed in an outer shell in a manner to define therebetween four isolated chambers upstreamly positioned two of which surround the first expansion chamber and downstreamly positioned two of which surround the second expansion chamber. The first expansion chamber is connected through respective flanged openings to the upstreamly positioned isolated chambers to allow these chambers to show a sound damping effect. The upstream and downstream portions of the second expansion chamber are connected through respective groups of perforations to the downstreamly positioned isolated chambers to allow these chambers to show a sound damping effect.

摘要： A dual spark plug ignition engine is equipped with an EGR system. The two spark plugs in each combustion chamber are simultaneously energized to produce sparks to ignite the charge in the combustion chamber under a normal engine operating conditions, whereas the spark plugs are energized with a predetermined phase difference from each other under high power output engine operating conditions.

摘要： A cylinder head of an internal combustion engine is formed with concavity. Two flat protruded portions are formed on the spherical surface of the concavity and their planes intersect each other at a location slightly below the vertex of the spherical surface. At the two flat protruded portions, intake and exhaust valve seats are disposed. A combustion chamber is defined by the spherical surface, the surfaces of the flat protruded portions and the piston crown.

摘要： Exhaust gases, which are slightly cooler than normal due to NOx suppressing ignition of the charge containing a large amount of recirculated gas by dual spark plugs, are exhausted via a large diameter exhaust valve to reduce the time for which they exceed the speed of sound and transfer heat to the cylinder head to maintain a high CO and HC oxidizing temperature. The exhaust valve is diametrically opposed to the inlet valve and has a cross sectional area of 19 to 24% of the cylinder bore.
