Abstract

The invention discloses a crankshaft corner mark signal acquisition system suitable for 165-series engine combustion analysis. In the crankshaft corner mark signal acquisition system, the upper end ofa torsional vibration transmission arm is connected with the free end of a crankshaft; a laser fluted disc is installed at the lower end of the torsional vibration transmission arm; a fluted disc pressing flange is pressed on the laser fluted disc; a laser sensor installing and adjusting device comprises a laser sensor correcting supporting frame and an installing structure with a self-tighteningoil seal; the installing structure with the self-tightening oil seal is connected with the torsional vibration transmission arm in a sleeving fitting mode; a laser sensor is installed on a sliding bracket; and a fixing supporting frame is fixed to a disk of the installing structure with the self-tightening oil seal, and the sliding bracket is fixed to the fixing supporting frame. The crankshaft corner mark signal acquisition system suitable for the 165-series engine combustion analysis is steady in structure and easy to install and operate, is widely applied to the combustion indicator diagram measurement and the torsional vibration test of a 165-series engine, and has high measurement accuracy and good use stability.

Description

technical field [0001] The invention relates to a crankshaft angle mark signal acquisition system, in particular to a crankshaft angle mark signal acquisition system suitable for combustion analysis of 165 series engines. Background technique [0002] The 165 series engine is a localized product with imported licensed technology. When carrying out reverse analysis of combustion performance, localized development or even optimization and improvement of this model, it is often necessary to perform dynamometer measurement and combustion analysis. Since this model does not reserve any engine phase angle detection method, it is impossible to accurately measure the crankshaft angle position and draw the indicator diagram, so it is also impossible to accurately evaluate and analyze its combustion performance. Contents of the invention [0003] In order to solve the crankshaft angle mark signal acquisition of 165 series engines and realize the accurate measurement of the dynamomet...
