These are some pictures I randomly choose to publish as the rest will be below as what my slide show player will show yeah. Have a check ya. Happy Viewing

Below are the slide shows of all the cars that participate in the Autoshow @ Putrajaya.

Introduction:

Timing belt
Is used to drive the engine's camshaft. The engine crankshaft utilizes a drive sprocket to connect with a larger camshaft sprocket via a timing belt. A typical timing belt is constructed of a fiber enforced rubber belt with horizontal ribs molded to the inside of the belt. Tension is held on the belt by a belt tensioner which is spring loaded, oil pressure activated or set manually. Timing belts can be used to drive accessories such as a water pump or power steering pump. Some engines utilize a timing belt to drive balance shafts inside the engine that help neutralize engine vibration. When a timing belt fails it will allow the horizontal ribs to shred allowing the driven shaft to stop or become misaligned resulting in engine operation failure. Each engine has a unique set of timing crankshaft, camshaft and accessory marks that can be located: timing belt marks or in a car repair manual.

Timing and Balance Shaft Belts with Tensioners

To check the condition of the timing belt (engine off) remove the top dust/safety cover from the upper section of the engine front by removing a few bolts you can access the timing belt. Next, using a flash light inspect the condition of the belt, check for cracks, especially at the base of drive teeth. If the timing belt shows signs of wear or if you are replacing it for maintenance purposes complete exposure of the belt and related components are necessary. For step by step instructions for your particular car engine you must consult a car repair manual.

Basic Replacement Procedure:

* Remove all obstructions from engine front, if an engine mount is in the way, support the engine from the top or bottom whichever is more convenient
* Remove upper and lower timing belt covers to gain access
* Remove or loosen timing belt tensioner to release the timing belt
* Remove timing belt and clean all debris from area
* Use a timing belt diagram to time the crankshaft to the camshaft - Timing belt diagrams
* Replace timing belt with tensioner (if needed)
* Re-install timing belt and reassemble as needed

Note: If the timing belt drives the water pump it is a good idea to replace it at this time to avoid failure. Occasionally when bearing tension is released and then reloaded it can have an adverse effect on internal bearings.

For manufacturer procedures on how to replace a timing belt on you particular car please consult a car repair manual.

Basic Maintenance
A camshaft is driven by the crankshaft of the engine by a timing chain or timing belt. The timing belt or chain needs to be replaced per manufacturer's specification they can wear out and fail without warning and stall the engine. Because a timing chain configuration is more durable when compared to the timing belt style a timing belt will need to be replaced more often, comparatively. Timing belts are more common in overhead cam engines and are more easily serviced.

How a Gasoline Engine Works

A gasoline engine operates on the principle of combustion. A fuel/air mixture is pulled into a cylinder, the cylinder is then closed off and the piston is thrust upward to create compression. A spark is introduced to ignite the mixture to create combustion to thrust the piston downward in the engine block.

There are a number of pistons inside an engine depending on the design, 4 to12 cylinders usually. The pistons are connected to a crankshaft through a connecting rod. Pistons fire consecutively to rotate the crankshaft inside the engine block. The oil pump pushes oil through the oil filter and then supplies oil to vital engine parts including the crank and camshaft, cylinder walls and piston rings, valve train, cam lifters and the timing gears or chain. Motor oil is used to lubricate and cool internal engine parts. Oil is pumped up through the engine, then returns to the bottom of the engine and is gathered in the oil pan.

Over Head Camshaft Engine

The cylinder head is connected to the top of the engine block and allows air/fuel mixture and exhaust into and out of the cylinder block. The cylinder head has the duty of holding the air/fuel mixture charge inside the cylinder as it combusts, forcing the piston downward. The cylinder head is connected to the engine block using head bolts, using a head gasket to seal both parts.

Over Head Cam Cylinder Head

A camshaft is used to open and close intake and exhaust ports by using valve train components. These components will vary depending on the design of the engine. There are primarily two styles of valve systems: over head cam which consists of a camshaft and lifter, and the in block system which consists of a camshaft, lifter, push rod, rocker arm. Both styles utilize a valve spring to hold the valve closed.

Camshaft In Block System

There are four main sections to the internal combustion engine.
1. Engine Block: (short block) note: a long block includes cylinder heads.
a. main engine block
b. crankshaft
c. pistons
d. piston rings
e. connecting rod pin
f. connecting rod
g. camshaft (in over head valve engines)
h. lifters (in over head valve engines)
i. oil pump
j. oil pump drive
k. oil pump pick up
l. gaskets and seals
m. freeze plugs
n. oil pan
o. assorted bolts

2. Cylinder heads
a. main head cylinder body
b. intake and exhaust valves
c. valve keepers
d. valve spring
e. valve spring retainer
f. valve stem seal

3. Air/fuel intake system
a. intake manifold
b. fuel injector
c. fuel injection system
d. air filter

4. Exhaust system
a. exhaust manifold
b. catalytic converter
c. muffler

Proper maintenance is crucial to optimum performance for every internal combustion engine. Follow your manufacturer recommended service schedules protect yourself by servicing your car regularly.

How a Neutral Safety Switch Works

An important car electrical component is the neutral safety switch. This switch disables the starter operation when the vehicles transmission is not in neutral or park. If the engine was allowed to start in gear the car would immediately begin to move once the engine started. Neutral safety switches are equipped on automatic transmission vehicles only. On most vehicles the reverse light function is integrated into the neutral safety switch. The location of the switch can vary; designs can include a transmission selector shaft or steering column mounting location. A neutral safety switch carries starter solenoid voltage when the ignition key is turned to the start position. This switch works the same way a normal switch would work except the neutral safety switch is controlled when the vehicle gear selector is moved throughout its range from park to 1st or low gear. When a neutral safety switch fails the starter or reverse lights will not operate.

Testing Neutral Safety Switch
Required Tools:
* Test Light/Voltage-meter
* Wiring schematic
* Neutral safety switch location (component location)

Test Procedure
* Locate the neutral safety switch
* Disconnect the wiring connector at the switch
* Using a test light or volt-meter test for power at the wiring harness with the key in the "engine crank" or the gear shifter in the "reverse" position. (do not start the engine)
* If power exists reconnect the neutral safety switch and probe outgoing wires at the connector.
* If no outgoing power is present the switch has failed and needs to be replaced.

Tip : If the engine will not crank over with the car in "park" push down the brake pedal and try cranking the engine over with the car in "neutral". What you are doing is bypassing the "park" position in the switch and now are using the little used neutral circuit. If in neutral the engine starts the switch is probably bad.

Tip: Sometimes a neutral safety switch can become misadjusted. This switch adjustment can change due to normal wear of mechanism that controls switch slider.

Other complications can occur if there is a loose connection somewhere in the system. While this condition is not a shorted circuit problem, it is a condition that simply breaks the flow of electricity intermittently. To troubleshoot this problem consult a car repair manual to locate the wiring schematic for your car. Repair the broken or shorted connection as needed and recheck system. Electrical problems are less complicated when the proper information is available. If technical assistance is needed, ask our team of certified technicians.

Details on may 1st new fuel subsidy system to be revealed in march 2010

This is the silver lining in a dark cloud. According to Domestic Trade, Cooperatives and Consumerism Minister Datuk Seri Ismail Sabri Yaakob, we will know the details of the new fuel subsidy mechanism in March 2010, ahead of the system’s expected implementation date in May 2010.Although most of us dread the thought of having to pay more for fuel soon (and with more hassle as well), at least now we will have a one to two month head start to planning our finances instead of only knowing at the very last minute.

Datuk Seri Ismail declined to provide any details (in an interview with NST), but he did say that it would make people happy. I am hoping that this could indicate a fair system that would not trouble the low to middle class income earners. Let’s hope the government has not been out of touch with the reality of things on the streets in formulating this new subsidy system, otherwise it will indeed be a bitter year of the tiger for us.

What we know so far is that foreigners (even those who consider Malaysia their home and work here with local and not typical expat level of salary) would definitely not get any subsidies because they will not hold the MyKad, which is said to be a key element in how the system works. Your MyKad will identify you (a newspaper report has even cited you need a thumbprint scan like at the airport with your passport or with your MyKad at the bank) and how much of subsidies you are eligible to get.

The system is said to be managed by MAYBANK, the first time this has been revealed in the newspapers, though I’ve heard rumors of this for months. A pilot project to test out the system will go live sometime in end March or perhaps April – a rather short test time for a large scale nationwide roll-out of a new system!

You could get between 200 to 300 liters of subsidies per month depending on various factors such as socio-economic and the dreaded engine capacity factor. The threshold is said to be 2,000cc and the Company cars are said to be not eligible for the subsidy. Once you run out of subsidised liters per month, you will have to pay full price, which is expected to be RM2.10 per liter for RON95.

Even for those who qualify for the liter amount of subsidies that they need every month, they will not likely to continue paying the RM1.80 per liter for RON95 and RM2.05 per liter for RON97 we are paying right now. Sin Chew Daily reports that the government is expected to announce a new subsidized price of RM1.90 per liter for RON95 and RM1.80 per liter for Euro 2M diesel. Nothing was said about RON97, so that can either be a very good thing or a very bad thing! But I have a feeling there will not be any ’subsidised’ option for RON97. If unsubsidised RON95 is RM2.10 per liter, unsubsidised RON97 might touch RM2.50 per liter!

Whatever it is, we’ll know the full details next month, if the minister keeps true to his word, and hopefully we’ll be ‘happy’. The March announcement date may coincide with a ‘registration exercise’ as mentioned in newspaper reports previously.

Proton Hybrid Concept car to revealed at Geneva on March 2010

PROTON HYBRID CONCEPT

PROJECTOR HEADLAMP

Italdesign will put up one different photo of the new Proton Hybrid Concept that they will be jointly exhibiting at the Geneva Motorshow from the 2nd to 14th of March 2010. Today’s teaser image is quite obviously the projector headlamps for the car. What I really want to see is how the back of the concept car looks like – so far none of the teasers or even the initial full image have revealed this. We might just have to wait until the march @ Geneva to find out more about this concept car by Proton designed by Italdesign.
