Title: INTERNAL COMBUSTION ENGINE FOR SADDLED VEHICLE
Abstract:
Provided is an internal combustion engine for a saddled vehicle, the internal combustion engine having a pressure sensor arrangement structure configured so that, even if a pressure sensor is provided to the single-cylinder engine, the pressure sensor does not interfere with an engine-related member located in the periphery of the pressure sensor, thereby making a manufacturing process more efficient. This internal combustion engine for a saddled vehicle is configured such that an intake port 95 and an exhaust port 101 are provided in the upper and lower surfaces of a cylinder head 35b, and an engine-related member 70 is disposed on one side surface 35b0 of the cylinder head 35b. An ignition plug 133 and a pressure sensor 144 which detects pressure in a combustion chamber 92 are arranged on the other side surface 35b1 of the cylinder head 35b. The ignition plug 133 and a hole 142 in which the pressure sensor 144 is installed are provided on axes oriented in the same direction.
