Fuel

Salam dan selamat sejahtera to all u guys.
Dekat sini sy ade barang baik punye nak intro kat u all.
Ini dorang kol Fuel saver, name lain penjimat minyak la. Skang kan minyak makin naik, x lame lagi pon akan naik lagi. So, ini ade la produk yang mesra alam, tak bagi pape efek buruk kat engine.



DeTaiLs

MyGreenOil ini ialah "Multifunctional Breakthrough Fuel Reformulator", Bile dicampur ngn petrol, petrol akan bertukar "immediately" menjadi lebih effisien dan perform pada thp optimum.

Benefit yang korang dapat dari Minyak ni:
  1. PENJIMATAN MINYAK - kenaikan harga minyak.
  2. PENINGKATAN KUASA DAN PERFORMANCE - kuasa optimum dgn kos yg rendah
  3. KOS MAINTENANCE DAPAT DIKURANGKAN - dari sparepart engin yg mahal
  4. PENCEMARAN PUN DPT DIKURANGKAN- dari asap ekzos
Ratio campuran ataupun cara penggunaan.

Petrol user
*1 mL Green oil = 1000 mL @ 1 Liter petrol

example: 50 litre petrol campur ngan 50mL Green oil

Diesel user
*1.2 mL Green oil = 1000mL @ 1 Liter Diesel

example: 50 liter diesel campur ngn 60 mL Green oil


Produk ini sudah diuji oleh:

USM:
Memberi keputusan bahawa Mygreen oil memberi kestabilan pada kelajuan engin pada keadaan pegun

SIRIM:
Sampel MyGreen oil telah dihantar kepada SIRIM, dan keputusan ujian menyatakan MyGreen oil adalah "non-acidic" dgn pH neutral 7. Ia juga 100% tiada asap ketika pembakaran berlaku.

PUSPAKOM
"Computerised Vehicle Testing Centre": Ujian dijalankan selama 6 bulan keatas kenderaan jenis Toyota Hilux Diesel (EURO Green Engine), sebelum dan selepas Mygreen Oil dicampurkan dgn minyak diesel. Keputusan ujian adalah, pengeluaran asap menurun sebanyak 50% hanya selepas 20km memandu. Sayangi udara bersih...hheheheh

Harge pulak:

1 Botol (60mL) = Rm 10
1 kotak (5 botol) = Rm 50 (Beli byk gua potong lagi harga kasi murah)
1 kotak ( 12 Sachet)= RM 14 (khas ntuk rider) nak beli satu sachet pon bole. Kasi roger je ngn gua.

Ley emel: asrul2k_kaka@yahoo.com
kol pun ok (hp): 013-2006594


Penghantaran:
Lembah klang ( shah alam, keyL, klang, meru, etc) : C.O.D or sy antar kat tmpat anda. hihihihi...minyak dah save. hihihi
Luar klang: Gune pos le. ape lagi..huuhuhu


TESTIMONIAL

"I first tried using Mygreenoil in my Nissan Serena. The immediate feeling I got was the smoothness and improved power. I continued using MyGreeenOil up to ten tankfuls and I notice that the engine became even more quieter and much more smoother and my fuel consumption improved by an average of 3 to 4 cents a kilometer. : i.e. previously I was getting 21 to 22 cents a km and on the last count I was getting 16 to 17 cents a km.


With my Citroen ZX, I was doing previously 20 to 23 cents a km and now I am now getting 17 to 19 cents a km. Right from the first tankful, I immediately felt power improvement and a much quieter and smoother engine. Now, after passing after 7000 km and although I have not changed my engine-oil, I still feel improved power, smoothness and quietness in the engine.

Surprisingly, when I went to change my engine oil, my mechanic told me that my engine oil viscocity and color/clarity has not changed much even after 7000 km, It is not black but clear....... amazing !"

"Hello, saya JOHN TAN, saya telah menggunakan mygrenoil selepas beberapa bulan, pruduk ini telah memberikan banyak faedah kepada saya, kuasa Perdana V6 saya naik banyak dan enjin kereta pun terasa senyap malahan yang penting sekali ialah ia memberikan penjimatan sebanyak 26% jika dibandingkan dahulu.

Tetapi apa yang menghairankan ialah apabila saya membuat servis minyak pelincir enjin selepas 10,000km minyak pelincir kereta saya bersih dan kelihatan masih boleh dipakai lagi ... saya amat puas hati dengan produk ini dan ucapkan terima kasih kepada pengasas produk ini"

Wastegate


W
ASTEGATE
Wastegate is a valve; diverting exhaust gases away from the turbine wheel in a turbocharged engine system. The diversion of exhaust gases will regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems in order to protect the engine and the turbocharger. One advantage of installing a remote mount wastegate to a free-float (or non-WG) turbo includes allowance for a smaller A/R turbine housing, resulting in less lag time before the turbo begins to spool and create boost.

External

An external wastegate is a separate self-contained mechanism typically used with turbochargers that do not have internal wastegates. An external wastegate requires a special constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate may be part of the exhaust housing itself. External wastegates are commonly used for regulating boost levels more precisely than internal wastegates in high power applications, where high boost levels can be achieved. External wastegates can be much larger since there is no constraint of integrating the valve or spring into the turbocharger and turbine housing. It is possible to use an external wastegate with an internally gated turbocharger. This can be achieved through a specially designed bracket that easily bolts on and restricts the movement of the actuator arm, keeping it from opening. Another route involves welding the internal wastegate shut which permanently keeps it from opening, but failure of the weld can allow it to open again.

External wastegates generally use a valve similar to the poppet valve found in the cylinder head. However they are controlled by pneumatics rather than a cam shaft and open in the opposite direction. External wastegates can also use a butterfly valve, though that is far more rare.


Wastegate size:

The size; is inversely proportionate to the desired level of boost and is somewhat agnostic to the size or power of the engine. One vendor's guide is as follows;

  • big turbo n low boost = bigger wastegate
  • big turbo n high boost = smaller wastegate
  • small turbo n low boost = bigger wastegate
  • small turbo n high boost = smaller wastegate

The CAM!!

Here I post some info about the cam of engine ( OHV,SOHC n DOHC)

OHV a.k.a OverHead Valve
An engine design where the camshaft is installed inside the engine block and valves are operated through lifters, pushrods and rocker arms (OHV engine also known as "Pushrod" engine). Although an OHV design is a bit outdated, it has been successfully used for decades. An OHV engine is very simple, has more compact size and proven to be durable.
Downside: it's difficult to precisely control the valve timing at high rpm due to higher inertia caused by larger amount of valve train components (lifter-pushrod-rocker arm). Also it's very difficult to install more than 2 valves per cylinder or implement some latest technologies such as Variable Valve Timing - something that could be easily done in a DOHC engine.


SOHC a.k.a Single Over Head Cam

In the SOHC engine the camshaft is installed in the cylinder head and valves are operated either by the rocker arms or directly through the lifters
The advantage is that valves are operated almost directly by the camshaft - easy to achieve the perfect timing at high rpm. Also it's possible to install three or four valves per cylinder
The disadvantage - an OHC engine requires a timing belt or chain with related components ; It's more complex and more expensive design.


DOHC a.k.a Double Over Head Cam

The type setup used in many today's cars. Since it's possible to install multiple valves per cylinder and place intake valves on the opposite side from exhaust valves, DOHC engine can "breath" better; meaning that it can produce more horsepowers with smaller engine volume. Compare: The 3.5-liter V6 DOHC engine of 2003 Nissan Pathfinder has 240 hp, similar to 245 hp of the 5.9-liter V8 OHV engine of 2003 Dodge Durango.
Pros: High efficiency, possible to install multiple valves per cylinder and adopt variable timing.
Cons: More complex and more expensive design.
Engine example: 4G generation
