Mohawks Lost: Flying in the Cia’s Secret War in Laos

為了解決如何 選 購 汽車機油的問題，作者Naekel, Gerald 這樣論述：

The eBook version of this book, here on Amazon, has most of the first chapter to read, while the print version preview is only a few pages long -- nothing I can control, but the eBook read is worth the couple minutes. The true stories of over 500 of my single-pilot combat flights, almost all of them

in Laos and North Vietnam during the Vietnam War. I spent about 22-1/2 months flying in the only Mohawk unit with the armed OV-1 Mohawks - until my timing and luck all ran out at the same time and I was medavac'd to the Air Force hospital at Clark AFB in the Philippines and then a series of Air For

ce and Army hospitals. This book, or most of it, was previously published as WAR STORIES - From an Army Pilot Flying in the CIA's Secret War in Laos and was for years an Amazon great seller Now it is has been updated, grammatically corrected with over a thousand changes, but pretty much the same 5-

Star book.The 131st Aviation Company, while based near Hue in South Vietnam (I Corps, just below the DMZ), flew entirely in Laos and North Vietnam for over seven years until the last months of the war. Our secondary base for over six years was Udorn RTAFB, Thailand where we flew nightly hunter/kille

r teams with the Air Force and Laotian forces attacking Chinese trucks and tanks across northern Laos, near (or sometimes across) the border far to the northwest of Hanoi. This was the war in the Plain of Jars (PDJ) and much of this was run from the secret CIA airfield at Long Teign (Lima Site-20a),

the most secret airfield in the world and home to much of the Air America fleet.Our two dozen Grumman OV-1 Mohawks were the only armed ones, and of the five Army Mohawk units, the other four operating only in South Vietnam, the 131st lost more aircraft and men than all the other units - combined.Ni

ghtly, from Phu Bai we flew pairs of SLAR/IR hunter/killer teams in southern Laos (Steel Tiger North and South) with the AC-130 Spectre gunships attacking the Ho Chi Minh Trail around the clock. There we faced huge amounts of flak and other heavy anti-aircraft fire that were not an issue inside of S

outh Vietnam.We ran SLAR, IR and VR (armed visual) missions around the clock in the southern ends of North Vietnam, including 24/7 SLAR missions right along the coast up to about Vinh. There the issue was Soviet SAM missiles, and flak and the rest of the heavy machine guns. Ditto for Laos.And we nev

er got a single man back out of Laos at the end of the war. You go down in Laos - and you are gone for good.

汽車引擎潤滑油性能測試

為了解決如何 選 購 汽車機油的問題，作者蔡東烜 這樣論述：

本研究主要是探討將齒輪油加入引擎內否可以達到與機油相同的潤滑效果，實驗測試內容為汽車引擎內加入齒輪油，之後進行實車路跑測試，且每一萬公里時進行引擎潤滑油性能測試，了解潤滑油性能狀況，期望可減少汽車機油使用，進而達到環保省能的效果。因此，為觀察汽車引擎潤滑油性能狀況,在長途行駛狀態下,不更換引擎機油(僅在水位不足時添加),於每行駛一萬公里時進行引擎潤滑油取樣檢驗,並分析潤滑油性能情況,了解長距離行駛狀態下，僅進行潤滑油添加的行車情況及平均油耗，最後並於達到行駛十萬公里時，分析汽缸磨耗進行引擎細部拆解、清洗、零件磨耗之量測記錄與觀察。實驗結果顯示：一、油耗分析表顯示，實驗期間整體平均油耗為11.

5km/L。本實驗測試油品為齒輪油級別為80W/90黏度係數類似機油15W/40。二、引擎內油汙、雜質過多，已造成部分機件磨耗。例如機油濾清器不良、機油氧化、軸承波司損傷、機油添加劑衰退、造成活塞油環咬死。三、油品黏度太高，潤滑效果不佳。齒輪油未能短時間被運送至零組件，因此會加大啟動時所受磨損，低溫起動將變得困難，清洗作用及冷卻散熱作用變差，功率損失導致燃油消耗增大。四、實驗車測試結果齒輪油當成潤滑使用是可行的，且宜定期或定里程檢查更換，建議一般中古汽車車主應可於每1-2萬公里之前後進行機油更換，不致影響及引擎組件。
