The invention discloses an engine cylinder head with a spark plug cooling channel, wherein the cylinder head is provided with a combustion chamber, a gas inlet channel, a gas outlet channel, and a vent channel; the gas inlet channel and the gas outlet channel are communicated with the combustion chamber; the surface of the combustion chamber is provided with a gas inlet, a gas outlet and a spark plug mounting hole; the other end of the spark plug mounting hole is reserved on the wall of the vent channel; the outer surface of the cylinder head is provided with a plurality of transverse radiating fins; the longitudinal retaining walls are arranged between the radiating fins at the mounting side of the spark plug of the cylinder head; and the retaining walls, the outer wall of the cylinder head and the radiating fins form a lateral cooling air channel. The invention comprises a special cooling channel near the mounting part of the spark plug, and therefore, cooling air can directly pass through the special cooling channel without entering into the cylinder head, so as to introduce fresh cold air to effectively cool spark plug and the parts around spark plug, thereby confirming great performance of the spark plug.
Description
technical field [0001] The invention relates to an engine cylinder head, in particular to an engine cylinder head with a spark plug cooling channel. Background technique [0002] The engine cylinder head on the current motorcycle seals the upper part of the engine cylinder, and forms the combustion chamber of the engine together with the top of the piston and the cylinder wall. In addition to the combustion chamber, the cylinder head is also provided with an air intake passage, an exhaust passage, an air passage and a spark plug installation hole. The spark plug installation hole is located in the air passage and communicates with the combustion chamber, and it is used to install the spark plug. The intake port and the exhaust port intersect with the combustion chamber of the cylinder head, forming intake holes and exhaust holes on the surface of the combustion chamber. There are many heat sinks on the outer surface of the cylinder head to increase the heat dissipation area...
