Liebherr'sLI3 Common Rail Injector in Field Test at an Iron Ore Mine in Australia，Demonstrated an above-average 20,000 hours of operation。

Of the many mines in Western Australia,，Liebherr'sLI3 Common Rail Injector shows its full performance potential。In a field test with one of the world's largest mining companies，This injector technology drives Liebherr's 12-cylinder dieselVType a engine。Installed at LiebherrR 9400 Mining ExcavatorDThe 9812 engine reached its planned service life after 20,000 hours of use.。

But installed in it.LIThe fuel injector has not yet reached the end of its life，In this endurance test,，They last a staggering 25% longer than previous versions of the same product%。

“Actually，We will have a large diesel engine.

The fuel injection system life of the is only rated at 15,000 hours。”

Nicolas CouanonExplained：

Generally speaking，15000 hours is the standard life of a component used in non-road applications。In field tests in Australian iron ore mines,，The test plan also provides the option of replacing the injectors after this period。However，During the actual test，It can also show continuous fuel injection performance.。So，The fuel injector may not need to be replaced。On this premise,，It can better reflectLI3 over an additional 5,000 hours，Set a new record for running time。

·Reliability and durability are crucial criteria.·

LIThe 3 common-rail injector platform has been specifically designed by Liebherr's component products division for large diesel applications operating in harsh environments.。The climate in the Pilbara region of Western Australia is extremely harsh.，Summer temperatures reach 40℃Above，Floods and tropical cyclones are also part of the typical local climate.。But for such extreme weather conditions,，This is the perfect condition to demonstrate the durability of Liebherr's large diesel injectors.。With double wall housing，For flat control valves and coating assembliesLI3 can withstand up to 10gVibration of impact load。In addition，Continuous zero static leakage across injector platform，And minimal dynamic leakage，This has made a greater contribution to the improvement of engine efficiency.。
