MOTOR DE COMBUSTION INTERNA REFRIGERADO POR AIRE EQUIPADO CON UN SENSOR PARA DETECTAR UN ESTADO DEL MOTOR

SE REFIERE A UN MOTOR DE COMBUSTION INTERNA REFRIGERADO POR AIRE QUE COMPRENDE: UN CUERPO DE MOTOR, UN SENSOR ACOPLADO AL CUERPO DE MOTOR PARA DETECTAR UN ESTADO DEL MOTOR Y UN PROTECTOR QUE CUBRE EL CUERPO DE MOTOR PARA DEFINIR UN CONDUCTO DE AIRE DE REFRIGERACION QUE RODEA EL CUERPO DE MOTOR, CARACTERIZADO PORQUE EL SENSOR Y UN CABLE ELECTRICO CONECTADO AL SENSOR ESTAN DISPUESTOS EN EL CONDUCTO DE AIRE DE REFRIGERACION The present invention provides an air-cooled type internal combustion engine. With the simple structure, the protection and cooling effect for the sensor and the cables connected to the sensors can be ensured. Besides, it is very flexible to arrange the sensors. The air-cooled type internal combustion engine forcedly cooled by the cooling fan (40) has a protection cover (45). The cylinder head (3) and the cylinder (1) are covered by the protection cover (45) to form the wind passage (46) for the cooling wind. The oxygen concentration sensor (70) installed on the cylinder head (3), the oil temperature sensor (75) installed on the cylinder (1) and the cables (71, 76) connected with each of the sensors (70, 75) are arranged in the wind passage (46). Each of the cables (71, 76) is arranged at the place that is more close to the upstream of cooling wind than the cylinder head (3) and the cylinder (1).
