摘要： PURPOSE:To obtain the titled filter with good filterability and high reliability by forming a filter member in such a manner that a continuous recessed and protruded shape is provided in the flowing direction of a fluid and pleats are formed on the filter surface thereof concentrically. CONSTITUTION:A filter member 1 has a continuous recessed and protruded shape toward the flowing direction of a fluid and said shape is integrally molded in an almost concentrical circle form to the right angle direction against the flowing direction of the fluid. At the same time, pleats 11 are formed over the entire surface of a filter surface and, as the whole, molded in a concentrical pleat form. In this filter member, the fluid containing fine particles is flowed into the filter member 1 through a punching metal 3b and, after fine particles are removed, the purified fluid is flowed out through a punching metal 3a. As the result, the filter has a wide filter surface and the fluid is uniformly passed through the filter surface as well as pressure loss due to passing resistance is reduced and said filter has good collecting efficiency, excellent durability and high reliability.

摘要： PURPOSE:To surely ignite the mixture and stabilize the combustion, by applying a high voltage from a continuous high voltage generator to a discharge electrodes in a cylinder. CONSTITUTION:When a piston 14 has moved from a suction process into a compression process and the angle of the crankshaft has become 160 to 60 deg. before the compression top dead center, a rotary electrode 53 of a distributor 50 starts facing its stationary electrode 54 and the high voltage of about 4 to 10 KV is applied from the continuous high voltage generator 30 to the spark plug 20 of the cylinder. Thereby, spark discharge is started between the discharge electrodes 21, 22 of the spark plug 20. The spark discharge lasts with a current of about 5 to 25 mA for the time when the rotary electrode 53 faces the stationary electrode 54. When the piston 14 has risen further and the angle of the crankshaft has become 40 to 5 deg. before the compression top dead center, an instantaneous high voltage generator 40 generates a high voltage of about 10 to 20 KV. This high voltage is applied to the spark plug 20 to cause stronger spark dischrge.

摘要： PURPOSE:To ensure combustion, by ignition burning activated mixture by means of a 2nd ignition plug by mounting a 1st ignition plug for activating mixture to a radical formation chamber installed so as to communicate with a combustion chamber. CONSTITUTION:A radical formation chamber 20 with little volume communicated through a combustion chamber 11 and a passage 19 is shaped to a cylinder head 12, and a 1st ignition plug 21 is mounted so that a discharge electrode 23 be positioned at an inward portion of the chamber 20 while a 2nd ignition plug 22 is installed to the combustion chamber 11. Electricity is conducted to the 1st ignition plug 21 through 1st and 2nd high tension generators 30, 40. The 1st high tension generator 30 is arranged so as to periodically generate high tension regardless of the revolution of an engine, and the 2nd high tension generator 40 is done so as to perform self-maintained discharge to the discharge electrode 23 of the ignition plug 21, thus activating mixture.

摘要： PURPOSE:To reduce ignition failure factor and vibratory noise and fuel cost by leading scavenging flow into the cylinder in a particular direction with a scavenging flow chamber in the cylinder block. CONSTITUTION:A scavenging flow chamber 26 is formed in a cylinder block 2, and scavenging flow is led from the scavenging flow chamber 26 into the cylinder 5 in a direction at right angles to the axial direction of the cylinder. In the scavenging process, air-fuel mixture led as scavenging flow into crank chambers 6 and 7 is led through scavenging paths 22 and 23 into the scavenging flow chamber 26, and a gentle flow is obtained with the direction of the flow changed to a direction normal to the axial direction of the cylinder 5. With the movement of the piston 9 toward the bottom dead center scavenging holes 27 are opened to permit gentle scavenging flow along the top wall of the piston 9 into the cylinder 5 in a tangential direction with respect thereto. In this way, air-fuel mixture can be supplied such that it is not mixed with the residual gas but in a laminar state. Thus, it is possible to obtain engine operation by ignition after compression and thus achieve the intended end.

摘要： PURPOSE:To improve scavenging efficiency, by opening a scavenging port, into which dilute fuel-air mixture or air is introduced, earlier than a scavenging port into which dense fuel-air mixture is introduced, relating to an uniflow system opposed piston type 2-cycle engine. CONSTITUTION:Dilute fuel-air mixture or air is introduced into a cylinder 5 through scavenging pasages 24 and 25 first, and residual gas inside the cylinder 5 is scavenged through an exhaust port 13. Since, at that time, scavenging ports 28 and 29 open toward a center part of the cylinder 5, dilute fuel-air mixture or air flows to an ignition plug 12 and the exhaust port 13, thus, residual gas is scavenged of effectively. And scavenging ports 26 and 27 open later than scavenging ports 28 and 29, dense fuel-air mixture is introduced into the cylinder 5 through scavenging passages 22 and 23, a dense fuel-air mixture layer is formed at a head of a piston 9. Thus, scavenging effeciency can be improved and satisfactory burning can be achieved.
