TH74170A - Engine sensor mounting structure - Google Patents

Abstract

DC60 (17/06/47) to protect the sensor which is installed on the outer wall of the crankcase from Getting heat radiation at Formed by the cylinder and muffler And enhances the work, including the installation of the crankcase detector and repair Maintenance Engine Know 1 has a crankcase 2 crankshaft that has It is supported to the crankcase 2 to rotate around the 3-axis protruding in approximately horizontal direction, cylinder 6 supported on top of the crankcase 2, and detector 25, which are mounted to The outer wall 11 of the crankcase 2 to measure engine driving conditions, a detector 25, was installed to the outer wall 11 of the crankcase 2 under the crankshaft 3 axis. The cover assembly 29 for covering the detector 25 has been formed into a single piece to Extend outside the outer wall 11 of the crankcase 2 in the direction along the outer surface of the crankcase 2 to protect the sensor, which is mounted to the outer wall of the crankcase. from Getting heat radiation at Formed by the cylinder and muffler And enhances the work, including the installation of the crankcase detector and repair Maintenance Engine Know 1 has a crankcase 2 crankshaft that has It is supported to the crankcase 2 to rotate around the 3-axis protruding in approximately horizontal direction, cylinder 6 supported on top of the crankcase 2, and detector 25, which are mounted to The outer wall 11 of the crankcase 2 to measure engine driving conditions, a detector 25, was installed to the outer wall 11 of the crankcase 2 under the crankshaft 3 axis. The cover assembly 29 for covering the detector 25 has been formed into a single piece to Extends outside from the outer wall 11 of the crankcase 2 in the direction along the outer surface of the aforementioned crankcase 2

Claims (4)
