Abstract

DC60 (03/10/56) to provide an ignition coil layout structure for internal combustion engines which can This makes the parts layout compact and can simplify wiring. Various electrical connection assemblies consisting of spark plug 45j 45j caps provided in cylinder head 33 are tilted forward, 17lj joint electrical connectors for electrical wires at It is connected to a variety of sensors that are provided in the body. The throttle valve 25 mounted to the intake manifold 23 and the electrical connector 24j of the injector 24 provided for in the intake manifold are arranged on the same side. Compared to the intake passage 23, the ignition coil 29 is arranged along the side surface of the cylinder 32 on the same side as the of the position of the upper electrical connection assembly relative to the intake manifold 23 in order to be superimposed on the cylinder 32 as seen in the side view. To provide an ignition coil layout structure for internal combustion engines which can This makes the parts layout compact and can simplify wiring.

Compared to the intake passage 23, the ignition coil 29 is arranged along the side surface of the cylinder block 32 on the same side as the of the position of the upper electrical connection assembly relative to the intake manifold 23 in order to be superimposed on the cylinder 32 as seen in the side view.

Claims (3)

Disclaimers (all) that will not appear on the advertisement page: 1.Motorcycle ignition coil layout structure Where the internal combustion engine (30) forms in the vehicle is the front part of the power unit (20) that is supported by the motorcycle's chassis (4) (1) and has an intake passageway (23), which Extending from the top of the cylinder head (33) that has been tilted forward. A spark plug cover (45j), which is an electrical connection to the spark plug (45) mounted on such a cylinder head (33), is placed on one side of the intake manifold (Lp) axis of the Passage of such ID (23), when viewed from a top view. And the ignition coil (29) is positioned on one side of the cylinder block (32) on the same side as that side, with its characteristics The ignition coil (29) is mounted on the said power unit (20) through the support brackets (28) and is positioned along the side surface of the aforementioned cylinder block (32) at one of the stacked positions. Over the said cylinder block (32), when viewed from a side view, the high-lead wire (45c) of the aforementioned ignition coil (29) is positioned in the presence of the electrical connector (29j) that connects. Connect such high-tensile wire (45c) to the ignition coil (29) placed towards the rear of the support arm (29a, 29a), which attaches the ignition coil (29) to the support bracket (28). As mentioned, and the high tensile (45c) cord is bent downward and to The way forward from the aforementioned electrical connector (29j) and the spark plug cover (45j) of such high tensile wire (45c) is worn onto the spark plug (45). 2. The motorcycle ignition coil layout structure, according to claim 1, is characterized by a power unit (20), such as in such a manner that the crankcase (31) of the internal combustion engine (30). It extends to the rear, on the same side as the position of the aforementioned ignition coil (29), to form the rear part of the aforementioned power unit (20) as the transmission chamber. And a power transmission set Continuously variable, the belt type (46) is positioned on one side of the transmission chamber, with the transmission chamber covered by the transmission hood (92, 36) of One side in order to cover the aforementioned continuously variable transmission belt type (46); And such ignition coil (29) aligned along the side surface of the said block (32) shall be aligned on the same side of the said cylinder block (32) when This is compared to the outermost straight line (Ls) that connects the front edge (34f) of the cylinder head cover (34) and the front edge (92f) of the aforementioned powertrain cover (92, 36). Pictured above 3. The motorcycle ignition coil layout structure according to claim 1 or 2, with the characteristics of Such support brackets (28) have hooks (28eh) for attaching the grounding cable (173) of the vehicle body.
