Can RON 95 fuel be used???

As of now, the government has announce that RON 95 fuel will be replacing RON 92 due to the fact that RON 92 fuel is of low grade and causes engine knocking or pinging. But what is knock or ping??? It is the sound that is being produce by the engine when uncontrolled burning or detonation occurs within the combustion chamber. This causes the piston to vibrate during combustion thus creating a metallic "pinging" sound which is also known as knock. This happens when the octane rating in the fuel is relatively low which causes pressure and temperature within the combustion chamber to rise higher then normal. As this happens in the long run, engine performance degrades from time to time. As to the topic above, Can RON 95 be used as an alternative depends on the engine and the performance which the fuel can produce. For example, RON 97 fuel can produce better performance and better anti-knock quality then RON 95 can due to the difference in octane rating. Another example is that most engines which are all running EFI (Electronic Fuel Injection) systems are in need of fuel with higher octane ratings which makes the engine run better, cleaner and produce more power. Researches have shown that RON 95 can produce the same performance and anti-knock quality as RON 97 and can be used on most cars. RON 95 fuel is also a cheaper alternative to RON 97 fuel due to price range.

Below are the list of cars that can use RON 95 fuel.....

Checking Your Spark Plugs Conditions (Fault Diagnosis)

Spark plugs are important as it ignites the air and fuel mixture within the combustion chamber during the power stroke. But spark plugs do fail from time to time due to excessive usage. Due to these, spark plugs are replaced according to manufactures specification. During replacement, the spark plugs which have been taken out from the engine will be checked to see the engine condition. These are the common conditions which tells weather your engine is in good condition or not....


Appearance

Conditions

Possible cause

Normal
Light brown, tan or grey firing end.

A good indicator that the plug is functioning correctly and general engine conditions are good.

Dry and wet fouling
Fouling, either dry (top - matt black, sooty) or wet (bottom - gloss black, sticky),


Can be caused by many different conditions. Carbon deposits build up when the plug fails to fire correctly and burn them off. Air/fuel mixture too rich, choke stuck on, electrical problem, extended periods of low speed driving, plug heat range too cold. All should be investigated

Overheating
When overheating occurs, deposits which have accumulated on the insulator tip may melt and give the tip a glazed appearance

Possible causes are overadvanced ignition timing, air/fuel mixture too lean, water or oil level too low, plugs not fitted (tightened) correctly, plug heat range too hot.

Deposits
Insualtor nose and electrodes encrusted with a build of deposits - usually off white in colour.

This is often caused by oil leakage through the piston rings or valve seals. Could be due to the wrong viscosity of oil being used.

Lead fouling
Lead deposits on the insulator nose. These are usually a yellowish brown in colour.

Lead content of petrol used is too high. Try petrol with a lower lead content.

Breakage
Physical damage to the insulator nose.


Usually caused by abnormal thermal expansion in the combustion chamber. Maybe thermal heating or cooling shock. Causes as for overheating above.

Normal life
Growth of the plug gap during a plug's working life is normal. However, the increased gap will mean the spark is less efficient and hence fuel is wasted and strain is put on the ignition system.

Plugs are at the end of servicable life. Replace plugs as a set.

Abnormal erosion
This is accelerated growth of the gap


Due to the effects of corrosion, oxidation and reaction with the lead in petrol.

Melting
The electrode surface will probably appear lustrous and uneven.


Due to excessively high temperatures in the combustion chamber. Causes as for overheating above.

Erosion, Corrosion, Oxidisation
The surfaces of the electrodes are rough, in extreme circumstances the electrode material will have oxidised to the point of turning green

Possibly due to age, vehicle standing for a long time without use.

Lead Erosion
The ground electrode will appear worn away, the central electrode will appear chipped and the insulator nose will take on a yellowish brown.

This is due to chemical reaction between the nickel alloy electrodes and the lead compounds in petrol.

Sirim-Certified Tyres


PETALING JAYA, July 10 -- Vehicle owners should use only Sirim-certified tyres to ensure the safety of drivers, passengers and other motorists, said Road Safety Department director-general Datuk Suret Singh.

He said, using low quality and non-Sirim certified tyres were identfied as among the causes of road accidents.

"The safety of a vehicle depends a lot on using appropriate tyres as using non-Sirim certified tyres will not only jeopardise the safety of the driver and passengers, but also other motorists on the road," he said.

He was speaking to reporters at a news conference after the signing of a Memorandum of Understanding (MoU) between the department and the Malaysian Tyre Manufacturers Association on promoting tyre safety issues here on Friday.

The association involves Malaysian Association of Tyre Retreaders and Dealers Society, Tyre Retreading Manufacturers Association of Malaysia and Association of Tyre Importers, Kuala Lumpur.

Suret Singh said the MoU would extend and improve cooperation with tyre manufacturers in the department's efforts to restrict the import, distribution and selling of tyres that did not meet Sirim standards.

He said the department planned to carry out undercover operations with the customs department, domestic trade, cooperative and consumerism ministry and the police to ensure non-Sirim certified tyres were not sold in the market.

Proton Waja 2.0 (Putra GTi) totally made by Proton’s Fans

The so called new Proton Waja 2.0 which was created by Proton fans with extreme editing on the base model of the Proton Waja to be like the Putra GTI. Although it is fake but it looks nice and futuristic some how. From this however, it shows that Malaysians can design cars which is newer, better looking, and futuristic. We hope that Proton will in the future be able to use these for newer models. If there is any comments or questions just feel free to post it up.

Mazda Astina 323 BG series: Gear Shift Lever Problem

Today my Mazda Astina 323 had a problem while on the way back from work. The gearbox shift lever drop down like it fell off out of place and had to be pulled up and hold for proper shifting. This is how it looks like.... (can see the floor through that hole)
So I fixed it at home and found out that the rubber mounting which holds the lever in place was broken and beyond repair. So I tried using a flat and flexible metal plate mostly used to hold water filters on the wall to hold it in place. This is how its done.....


First loosen the 4 mounting nuts which holds the shift lever mounting plate at the bottom.




Then put the metal around the bottom part of the shift lever bracket to the mounting plate. Push the metal in between the body and the mounting plate as shown in the picture.



While putting the metal in between the body and the mounting plate, try to push it through untill the metal can be seen on top. Then pull it up like this.....



After pulling it up like that, try to pull the metal untill the shift lever is in place and tight between the shift lever bracket and mounting plate. Pull it untill it cannot be pulled. After that cut the remaining metal like so



Then bend the metal to hook to the mounting plate like this



Then tighten the 4 mounting nuts



After tightening those nuts, clamp the metal tightly to the mounting plate like so with a plier on the left and right side.



Last but not least stuff some rubber or small rubber hose at the sides to make it fit and put the round rubber to cover it

Then put back the center console and the gear knob and done. Now it looks like nothing happend. If there is any comments or questions just feel free to post it up. I will try to answer it.

My Ride Mazda Astina BG series

This is my ride the mazda astina which i have been driving for so long and did fix it up bit by bit. Now is running like new have a look..... and i will be posting up some repairs on this cars since there is no information on the web about this vehicle with the original engine B6 single cam carburetor. the engine is called B6-2E or refered as B6ME. This engine is no doubt a 1.6 litter single cam low powered engine but strong in one way.

Basic engine tuning

as you all know about how the engine works, tuning it to make it work better and faster means adding more air and fuel. But to do that needs more money, time, and effort. these are some basic tuning ways to make your engine move faster and more powerful.

Making bigger inlet and exhaust valves- bigger inlet and exhaust valves which means ports being machined to a "better" shape. so more air and fuel can go into the combustion chamber to be burned and also better escape of exhaust gasses.

Bigger pistons- bigger pistons makes the cc of the engine bigger. for example, an engine of a 1.6 litter being bored and fitted with a bigger piston to make it to a 1.8 litter engine. by making an engine with a higher engine capacity can make more horsepower.

Tuned exhaust and intake manifolds- with a tuned exhaust and intake manifold, will increase horsepower of an engine. because the engine can breath better and remove the exhaust gas better too. a well tuned intake manifold can make better air flow for each individual cylinder which allows more air and fuel to enter. this increases the volumetric efficiency of the engine. this also applies to the exhaust manifold which improves better escape of exhaust gasses.

Lightening parts- lightening your motor parts like the flywheel and crankshaft can contribute to more acceleration especially in lower gears. this is because less energy is being used to move these rotating parts. but it will not increase horsepower of the engine.

if there is more you would like to share or questions, feel free to post a comment. would like to hear it.

engine 4 stroke cycle

In order to increase the horsepower of an engine is to first understand the four stroke cycle within the engine. The four stroke cycle consists of intake stroke, compression stroke, power stroke, and exhaust stroke.

Intake stroke

The first stroke is the intake stroke. The piston

moves down the cylinder and creates a partial

vacuum in the cylinder. A mixture of air and fuel

is forced through the inlet valve into the cylinder

by atmospheric pressure, now greater than the

pressure in the cylinder. During this stroke,

the exhaust valve stays closed.



Compression stroke

The second stroke is the compression stroke.

The piston moves up in the cylinder with both

valves closed. The air and fuel mixture is

compressed and the pressure rises.



Power Stroke

The third stroke is the power stroke.

Near the end of the compression stroke,

the air and fuel mixture is ignited by an

electric spark from the spark plug. The

combustion that occurs causes a rise in

temperature and enough pressure to force

the piston down again



Exhaust Stroke

The fourth stroke, or exhaust stroke, the

piston moves up again and forces the burned

gases out of the cylinder and into the exhaust system.

Make your power window smooth


With any vehicle which has power windows or manual windows, it is best to spray silicon on the sides of the windows guides. This guide are located on the sides of the glass (marked in red circles) . Just spray into the guide and let the silicon liquid flow down. Hope it helps
