Abstract

DC60 (27/06/12) To make it possible to reduce fuel costs by burning thin intakes in four-stroke engines, where the spark plugs exposed to the combustion chamber are bolted. with a cylinder head with a number of intake channels One that opens to the combustion chamber. Spark plugs 26 are attached to the cylinder head 14 at a distance from the center of the combustion chamber 19, aligned with one intake port 20 of the number of intake vents. One, 20 and 21 arranged in a side-by-side relationship. where the channel is positioned on one end In the parallel directions of intake channels 20 and 21, the lead wall 142 is provided on the ceiling wall 19a of the combustion chamber 19 around the end open to the combustion chamber 19 of the intake channel 21 on one end leading wall. 142 will direct the intake air flowing into the combustion chamber 19 from the intake port 21 on one end in the condition to circulate It bypasses spark plug 26 to make it possible to reduce fuel costs by burning thin intakes in four-stroke engines, where the spark plugs exposed to the combustion chamber are bolted to the cap. cylinder with number of intake vents One that opens to the combustion chamber. Spark plugs 26 are attached to the cylinder head 14 at a distance from the center of the combustion chamber 19, aligned with one intake port 20 of the number of intake vents. One, 20 and 21 arranged in a side-by-side relationship. where the channel is positioned on one end In the parallel directions of intake channels 20 and 21, the lead wall 142 is provided on the ceiling wall 19a of the combustion chamber 19 around the end open to the combustion chamber 19 of the intake channel 21 on one end leading wall. 142 will direct the intake air flowing into the combustion chamber 19 from the intake port 21 on one end in the condition to circulate which flows bypassing the spark plug 26

Claims (1)

1. A four-stroke engine where spark plugs (26) exposed to the combustion chamber (19) are bolted to the cylinder head (14) provided with a pair of intake vents (20, 21) that have Side by side relationship, the intake port (20, 21) is opened into the combustion chamber (19), unique in that; The spark plugs (26) are attached to the cylinder head (14) at a position apart from the center of the combustion chamber (19) and aligned with one (20) of the intake manifold (20, 21); A guide wall (142) for the conduction of the intake air flowing into the combustion chamber (19) from one intake port (20) in order to circulate it bypassing the spark plugs (26) is provided on the The ceiling wall (19a) of the combustion chamber (19) around the open end of one of the intake ports (20) to the combustion chamber (19); The socket (143) is arranged in the center of the piston face (17) exposed to the combustion chamber (19); And the injection valve (108), which is able to inject the converted fuel into fine particles. With compressed air directly into the combustion chamber (19) and one end protruding into the socket (143) when the piston (17) is at dead center on the pair of intake vents (20, 21), the exhaust port (22) Address at the corresponding position Along with the other intake ports, that (21) and spark plugs (26) are positioned on top of the cylinder head (14) in such a way that the flaps (108) are enclosed by both intake vents. (20, 21) exhaust port (22) and spark plug (26).
