| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 102 === This research is the traditional lead-acid battery replacement petrol engine to start -type lithium iron batteries, gasoline and jet engine testing , research process into real vehicle performance and horsepower test machine performance test categories, the former conduct real car battery load , ignition and fuel consumption performance impact test waveform , and FTP-75 which follow two modes SFTP SC03 experiments under controlled experimental conditions , to the performance of lead-acid battery tester based on horsepower , more lithium-iron batteries different speeds and speed , the load on the battery , ignition and fuel consumption changes torque waveform stability , traction and exhaust emissions and performance of various concentrations of exhaust emissions .
Study results showed : the use of lithium iron batteries, battery charge load charge back into better performance ; ignition waveform and high stability ; actual road race fuel consumption fell by an average of 2 to 5% ; fuel consumption ratio under low speed average decrease 3.36 ~ 4.12% ; various speed ratio of CO emissions reduced 2.8~20.6%, HC reduces 35.7 ~ 98.4%; NOX reduced by 12.4 ~ 35.6% ; overall efficiency and effective horsepower 1.27 ~ 4.63%, improving traction output 5.6 to 7.4%. So in gasoline engines use lithium-iron battery , in addition to their longer life , but also can make gasoline engines more energy savings, increase the output torque of the engine horsepower and reduce exhaust pollutants effectively achieve carbon reduction targets.
