TOKEY BUSY

wa take over la.. ari ni 16/7/2008.. wa sedey banget bila dpt tahu DSAI dah ditangkap dgn cara yg tak sepatutnya oleh polis yg bertopeng... polis bertopeng?? gaban ker?? ultramen ker ?? menakutkan la malaysia ni..

DSAI dilayan bagaikan seorang penjenayah yang paling berbahaya didunia. Kereta pengiring polis berbelas2 buah mengiring dihari penangkapan beliau. gang2 mamak pun tak dapat layanan sehebat tu..

wa nak bukak satu cerita.. time PRU ari tu, wa ngundi kat lembah pantai, kws nurul izzah.. sblm masuk ke bilik megundi wa sempat menjeling ke meja polis yg terletak di sebelah bilik mengundi, time tu meja tu kosong.. entah kemana pegi pak polisi tu.. tp wa sempat baca sikit2 isi satu pamplet yg ada diatas meja tersebut.. pamplet tersebut keseluruhannya memburukkan DSAI. Kandungan pamplet tu, menuduh DSAI sebagai agen yahudi, Amerika dan sebagainya.. di gambarkan seolah2 DSAI merupakan musuh utama negara, mesti di musuhi, diperangi sedahsyat2nya.. timbul satu pertanyaan di pikiran wa, mungkinkah setiap polis kat malaysia ni tlh diberikan kursus yg module mcm BTN, dimana isinya semata2 menghentam dan memburukan2 DSAI utk menanamkan rasa benci dan meluat semua polis terhadap DSAI. ye la.. setakat polis yg hanya berkelulusan SPM, sejauh manalah sgt otak diorng ni blh berpikir..

Apa2 pun wa harap kepada semua pencinta keamanan dan keadilan, sama2 lah kita berdoa agar Allah akan melindungi mereka2 yg ikhlas berjuang utk kepentingan rakyat dan negara, yg ikhlas berjuang di jalan Allah. dan seterusnya memberikan kita taufik dan hidayah utk kita menilai mana yg baik dan mana yg buruk.

Semoga Allah memberikan pembalasan yg sewajarnya kepada mereka2 yg bersubahat dan terlibat dengan kezaliman dan perbuatan fitnah yg keji.. undang2 rimba yg diamalkan di negara ini, tidak byk yg dpt kita lakukan untuk membela mereka2 yg telah teraniaya .. hanya Allah tempat bergantung dan meminta pertolongan.

wa harap drama ni akan cepat berakhir dan seterusnya dapat meneruskan impian dan harapan sebahagian besar rakayt malaysia utk melihat dan menjadikan Malaysia ini sebuah negara yg lebih baik, maju dan makmur. InsyaAllah.

Alternative Energy (NGV)

Salam.................

Here I would like to share with you about the Natural gas or (NGV).

Fuel Description
• Extracted from underground petroleum reservoirs, composed primarily of methane.
Compressed natural gas (CNG) is compressed to 2,400-3,600 pounds per square inch in
specially designed and constructed cylinders.
Liquefied natural gas (LNG) is cooled to -260EF and stored in insulated cryogenic tanks.

Fuel Production
• Produced by extraction from underground reservoirs or in production of crude oil and oil refining.
• Natural gas is processed to remove water vapor, sulfur and heavy hydrocarbons, leaving mostly methane.
• Methane is formed from organic matter decomposed in the presence of heat or microorganisms. Also, processed from coal and oil.

Fuel Source
• Production is about 85% domestic when extracted from underground petroleum sources and oil refining pocesses

Engine Description
• Operates in internal combustion ignition engine with some vehicle modifications.
• Fuel is regulated to low pressure from high pressure vessels and injected into engine as a vapor.

Conversion kits are available.
• Dedicated or bi-fuel systems. Engine is optimized for one fuel on bi-fuel systems.

Vehicle Fueling
• “Slow” fill (as long as 8 hours) and “quick” fill (3 to 5 minutes) are available for CNG. LNG (stored at
260EF) fueling times are comparable with those for gasoline or diesel fuels.
• Pumping station equipment uses high pressure hoses and connectors (2,400-3,600psi).

Fuel Availability
• CNG fueling stations are located in most major cities and in many rural areas. Nearly 1,300 fueling stations are available across the country.
• Public LNG stations are limited. LNG is available through several suppliers of cryogenic liquids.

Marketplace Usage
• Estimates indicate there are more than 75,000 natural gas vehicles in the United States used mainly for fleets and more than 1 million worldwide.
• Auto manufacturers offer many types and styles of CNG vehicles.
• HDV manufacturers can install one of several available CNG or LNG engines in products they offer.
• Medium-duty and heavy-duty CNG vehicles operate in many applications including federal, state, and local government fleets; commercial fleets such as grocery stores; and package delivery fleets, such as

United Parcel Service.
• One of every five new transit buses in the United States is powered by natural gas. Many new school buses are natural gas-fueled.

Operational Performance
• Vehicle range for CNG and LNG depends on fuel storage capacity, but generally it is less than that of comparable gasoline or diesel vehicles.
• Power, acceleration, and cruising speeds are comparable with those of gasoline or diesel.
• Energy density of CNG is less, requiring more fuel for similar range as gasoline. Storage cylinder location and number may displace some payload capacity.

Maintenance Considerations
• High-pressure tanks require periodic inspection and certification.
• Some fleets report 2 to 3 years longer service life and extended time between required maintenance. However, manufacturers and conversion companies recommend conventional maintenance intervals.

Safety
• Pressurized tanks have been designed to withstand severe impact, high external temperatures, and automotive environmental exposure. Design changes have resolved problems responsible for earlier in service failures.
• It is important to fuel a natural gas-fueled vehicle in a well-ventilated area. Natural gas dissipates quickly in air when circulated.
• Natural gas is relatively non-reactive when it is not contained.

General Maintenance

UNDER THE HOOD AND VEHICLE

Windshield washerfluid
Check that there is adequate fluid in the tank.

Engine coolant level
Check the coolant level when the engine is cold.

Engine oil level
Check the level after parking the vehicle on a level spot and turning off the engine

Brake and clutch fluid levels
Make sure that the brake and clutch fluid levels are between the “MAX” and “MIN” lines on the reservoir.

Battery
Check the fluid level in each cell. It should be between the “MAX” and “MIN” lines.


OUTSIDE THE VEHICLE

Tires

Check the pressure with a gauge periodically when at a service station, including the spare, and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive wear.

Windshield wiper blades
Check for cracks or wear if they do not wipe properly.

Doors and engine hood
Check that all doors, the engine hood, the trunk lid and back door operate properly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure that the secondary latch keeps the hood from opening when the primary latch is released. When driving in areas using road salt or other corrosive materials, check for lubrication frequently.

Tire rotation
Tires should be rotated every 10,000 km (6,000 miles).

INSIDE THE VEHICLE

Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and other lamps are all operating properly and installed securely. Also check headlamp aim.

Warning lamps and chimes
Make sure that all warning lamps and chimes are operating properly.

Steering wheel
Check for change in the steering conditions, such as excessive free play, hard steering or strange noises. Free play: Less than 35 mm (1.38 in).

Seat belts
Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and retractors)operate properly and smoothly, and are installed securely. Check the belt webbing for cuts, fraying, wear or damage.

PENJAGAAN TAYAR KERETA

Tayar yang rosak boleh mengakibatkan kemalangan yg boleh mengancam nyawa pemandu dan penumpang. Selalu2 lah memeriksa tayar anda sebelum memulakan perjalanan. Perhatikan diantara satu bunga tayar dengan bunga tayar yg lain terdapat satu penyambung. Jika penyambung itu mempunyai ketinggian yg sama dengan bunga, bermakna tayar tersebut perlu ditukar dalam masa 3 hingga 4 bulan, bergantung kepada kekerapan perjalanan anda.

Di bawah ini di sertakan tips menukar tayar kereta.

1. Pilih saiz tayar yang sesuai dengan kereta anda. Jika menggunakan saiz tayar yg besar, kekuatan pecutan kereta akan menurun, speedometer tidak menunjukkan bacaan yang tepat, semua peralatan penyerap hentak akan lebih pendek jangka hayatnya.

2. Selepas mendapat saiz tayar yang sesuai, perhatikan di bahagian tepinya. Terdapat satu rangkaian nombor yang dicetak tenggelam ke permukaan tepi tayar. Rangkaian nombor tersebut adalah maklumat tarikh tayar tersebut dikilangkan (minggu dan tahun). maklumat ini blh digunakan utk tujuan keselamatan. kebiasannya tayar perlu ditukar selepas 2 tahun dikilangkan.

3. Perhatikan rangkaian nombor dan huruf yg dicetak timbul di bahagian tepi permukaan tayar. Sebagai contoh 205/50 VR16 bermaksud lebar tayar adalah 205mm, ketebalan(dari rim ke permukaan jalan) adalah 50% daripada kelebaran 205mm dan untuk kegunaan rim bersaiz 16 inchi. huruf VR bermaksud tayar itu sesuai untuk kelajuan sehingga 240km/j tanpa menjejaskan ketahanan dan kekuatan tayar.

4. Kebanyakkan tayar dibuat berdasarkan iklim sesebuah negara. Tayar import mungkin tidak sesuai digunakan oleh kereta di negara ini. Jangka hayat tayar mungkin akan menjadi lebih pendek.

5. Tayar sepatutnya ditukarkan kedudukan setiap 3 bln. Caranya, tayar depan kiri ditukarkan ke kanan belakang, dan tayar depan kanan ditukarkan ke kiri belakang.

6. Jika kadar kehausan bunga di bahagian tepi kiri dan kanan lebih cepat berbanding di tengah, ini bermakna tekanan angin di dalam tayar telah berkurangan.

Keta ni macam orang ler juga...kalau tak maintain...lame2 sakit ler dia...tak comey lar...ok...sekadar berkongsi ....untuk kerosakan @ penjagaan air cond kereta......

SERVIS AIRCOND KERETA

Tahukah anda bahawa selain bahagian enjin kereta aircond atau penyaman udara kereta anda perlu diperiksa dan diservis setiap 2 hingga 3 tahun sekali.. Mungkin ada yang tidak tahu atau tidak pernah langsung menyelenggara aircond kereta kesayangan sejak dibeli 5 tahun lalu..

Apa yang pomen buat masa servis aircond kereta tu?

1. memeriksa kandungan gas aircond.. kalau sudah kurang perlu ditambah (Jenis gas aircond kereta yang diluluskan oleh Jab Alam Sekitar ialah R134 / R134A.

2. cuci / bersihkan kekotoran dan habuk-habuk yang terdapat pada bahagian-bahagian aircond (spt cooling coil dsb)

3. memeriksa aircond compressor, tabung gas aircond - masih ok atau terdapat sebarang kebocoran

4. motor kipas aircond (aircond fan radiator) - masih berfungsi dgn baik atau sudah 'kong'tanda-tanda aircond kereta perlu diperiksa / diservis

Tanda-tanda aircond kereta perlu diperiksa/diservis

a. bila ON aircond enjin kereta terasa 'berat' (bukan berat sikit tetapi berat banyak)

b. bila ON aircond sekejap sejuk sekejap tak sejuk

c. bila ON aircond aircond fan radiator sudah berpusing dengan perlahan (tidak laju) atau kipas itu tidak berpusing langsung biasanya selepas servis aircond ni kereta anda akan lebih fresh.. enjin pun ringan (masa on aircond)..
