1、四川工商職業(yè)技術(shù)學(xué)院畢業(yè)論文四川工商職業(yè)技術(shù)學(xué)院畢業(yè)論文論文題目:2012款凱美瑞油耗高的綜合分析系別:機(jī)電工程系專業(yè):汽車檢測(cè)與維修班級(jí):汽運(yùn)10303姓名:鄒甫指導(dǎo)教師:張思楊第18頁(yè)共19頁(yè)四川工商職業(yè)技術(shù)學(xué)院畢業(yè)論文摘要21世紀(jì)是一個(gè)科技時(shí)代,更是一個(gè)能源問(wèn)題的時(shí)代。伴隨著汽車保有量的加大和石油資源的枯竭,以及全球金融危機(jī)的影響,汽車節(jié)油已經(jīng)成為全球的問(wèn)題。對(duì)于有車一族的來(lái)說(shuō)更是相當(dāng)?shù)闹匾,F(xiàn)在的電控發(fā)動(dòng)機(jī),它環(huán)保,高效節(jié)能,提高汽車發(fā)動(dòng)機(jī)的在不同工況下的性能。它將傳感器采集的信號(hào)傳給電腦,然后提供給噴油嘴和點(diǎn)火器準(zhǔn)確的噴油量與點(diǎn)火時(shí)間,以達(dá)到不同工況下最佳的空燃比要求值和點(diǎn)
2、火正時(shí)。發(fā)動(dòng)機(jī)油耗過(guò)高是指汽車的百公里油耗超過(guò)標(biāo)定值。2012款凱美瑞2.0L官方綜合工況油耗:7.40L/100Km,2012款凱美瑞2.5L官方綜合工況油耗:7.60L/100Km,發(fā)動(dòng)機(jī)油耗異常偏高,則說(shuō)明發(fā)動(dòng)機(jī)、底盤、車身等汽車本身某方面或駕駛操作習(xí)慣有問(wèn)題。本文著重討論由發(fā)動(dòng)機(jī)和底盤等汽車本身因素導(dǎo)致油耗高的分析,以及駕駛員的駕駛保養(yǎng)習(xí)慣帶來(lái)的油耗問(wèn)題。在論文的最后討論了2012款CAMRY油耗過(guò)高的故障排除和改進(jìn),以及如何駕駛保養(yǎng)帶來(lái)的節(jié)油優(yōu)點(diǎn)。關(guān)鍵字:底盤,發(fā)動(dòng)機(jī),燃油消耗,故障診斷,省油節(jié)油第18頁(yè)共19頁(yè)四川工商職業(yè)技術(shù)學(xué)院畢業(yè)論文AbstractTwenty-fi
