請教E46 M54 水龜開啟溫度~
 

最近因該是天氣炎熱的關係,發現水溫有點偏高....
之前從冷車行駛中~水溫大約到達97度後水龜開啟~就可一直降溫至88度(看路況)
夏天來臨後~水溫約98~99度~才開始降溫~這樣正常嗎~????

另問請教M54引擎用的水龜有低溫的嗎~或可從GT1電腦設定開啟時間??

感覺不太正常 ,

這幾天白天氣溫都37~38度 , 不管有沒有塞車 , 從未超過95度 , 最低還到85度 .

去檢查一下吧 ...

97度開始做大循環......差個2度算正常.......

低溫水龜是大改車在用的,防止工作溫度瞬間破表所以提早做大循環

以原廠車來說不達瞬間飆高水溫標準是多餘的,低溫水龜上去反而拉長到達引擎工作溫度,導致電腦判定水溫過低做噴油提溫的動作而耗油.......

m54的電子節溫器，是97度全開的.
它上面有一個溫度sensor，它只是一個sensor並不是用來控制水龜開啟的，所以用gt1是無法設定水龜開啟溫度的!

M54 是電子水龜喔 是電腦供電可以開啟的喔

Integrated housing thermostats differ from traditional thermostats, as they are an all-in-one bolt on solution, with the thermostat and housing integrated into each other. This is a growing segment of thermostats with a large number of vehicles entering the replacement window.

MotoRad offers superior application coverage on integrated housing thermostats, at nearly 120 SKU’s, accounting for 91% application coverage. Housing thermostat sales have been growing at a rapid rate since they became very popular on 2003 vehicles. In 2014, roughly 40% of all new vehicles manufactured came equipped with an integrated housing thermostat and that trend continues to climb in 2015. The growth of this product segment will continue for years to come.

MAP Controlled Integrated Housing Thermostats
Integrated MAP controlled housing thermostats are the next generation of integrated housing thermostats. They allow additional regulation of operating temperature via maps stored in the ECU. They are specifically designed for maximum efficiency to provide adaptive, on-demand cooling based on the engine’s overall performance and load state. This results in lower emissions and fuel consumption, while providing greater engine output.
