Cars wasteful because Air Fuel Ratio is not optimal

Machine settings for Air-Fuel-Ratio is the ratio of fuel to the air intake during combustion in the engine. Mixture ratio is wrong and wasteful to make your car not powered. How do we know we have the optimal AFR?

Three kinds of conditions-Air-Fuel Ratio

    RICH: The ratio of the mixture into "rich" when the supply of fuel into the combustion chamber is greater than the required alias excessive. Excessive levels of fuel combustion does not make better, instead they were less than optimal both from the energy produced as well as efficiency.
    LEAN: While the conditions in which less fuel and excess air content called a "lean".
    STOICH: And the condition is said to ideal if the amount of intake air in accordance with the amount needed to burn all the fuel and the condition is called "stoichiometric" and often abbreviated as "stoich".

    In the automobile gasoline mixture ratio between air: the optimal gasoline is between 14.7:1 to 14.1:1.

AFR practical indications were optimal or not
Well, there are practical ways to find out whether or not fitted AFR settings. One of them can be detected by observing the engine RPM at idle (quiet place with the engine running). If the engine RPM down ride, this is a sign of setting the ratio of fuel and air are less fit.

Therefore, beware of the unstable engine in idle position. Besides resulting in a more wasteful consumption, it is possible the engine suddenly died when the car is racing toward us in the middle of the road.

A better way to find out if the AFR is not fit through the exhaust emission test. When the emission test results showed levels of HC and CO are too high, meaning the fuel entering the combustion chamber is too excessive.

Resetting the ratio of air and fuel mixture (AFR), commonly called the setting of CO and can be done by the mechanics in car maintenance workshops in general.

Check Engine Sound

How to detect sound with 2 tools; use a special stethoscope to make a machine or mechanic's called Stethoscope. Can also use an iron rod or screwdriver that both ends of iron.

Studies analyzing the sound on this machine is usually applied to each vehicle manufacturer. Recently there was an open class engine sound on their mechanical training division.

This class is devoted to learning the sounds produced by the engine. Especially sounds strange or abnormal that indicate a malfunction. The definition itself is the voice sound engine derived from the engine components. Sound exhaust and chain wheels are not included.

To be able to analyze a strange noise in the engine, it takes knowledge about the machine. Minimal understand about the components of what is behind the engine cover and know the exact location. Without it, this science will be in vain.

In addition, there are several things to consider when trying to diagnose an abnormal engine sounds. First, try not parked motor condition using middle standard. Because it will arise when the spin machine vibration accelerated.

Actually, may be parked using the standard middle, but in the middle should dialas standard foot wear rubber or a material that can dampen vibration. Because the vibration caused could lead sound that can interfere with analyzing the sound of the engine. Nor is using the standard side stand or the side.

Should the bike is held only. So need one more person to do so. We're doing sound checks. Can ask for help from friends or relatives for holding the motor.

Then, after the engine started and somewhat diblayer-sailed a bit, try to carefully first whether there are other disturbing sound or not. If there is, make sure the voice was coming from where. When sound came from the body, the body that should be removed first. Let not interfere with the process of checking the engine sound.

Then that must be remembered, as will diagnose the engine, fuel tank contents should be full. Because if not, the empty space in the tank could also result from exposure to noise vibration motor. Even the exhaust sound that can also be annoying, should be closed cloth.

If you have, make sure the gear in neutral position (N). Except when they want to check the engine sound coming from the transmission gear. Then the spin machine is idle aka langsam conditioned. Well, now lives entered the stage of diagnosing the engine sound.

Do check at some point the engine surface to obtain the most loud sounds (treble). Because of the potential component is behind the engine which sounded loud it was problematic.

When looking at the sound of the engine, do snaping (open gas cap) uniformly up to 2500-3000 rpm engine speed. Time interval approximately langsam for 2 seconds, then when gassed up to 2500-3000 rpm spin just 1 second.

Tips that are not disadvantaged when the content of the fuel

Often heard saying "gas station at the location A in size is less accurate. I am content there, much less than the failure by the location of B whereas the number of digits the same liter." Well do not play carelessly accused first. Although the integrity is still a question mark but could be the cause is a factor yourself. How come? Maybe you have the wrong measure, yet the size you are using estimates only. But there are also technical factors that you can control.

Here are tips and translation so that you get proper fuel:

•     The contents of petrol / diesel in the morning.
•     Stations accommodate fuel (gasoline / diesel) in the soil. Well at the time of the morning the ground temperature is still cold so the fuel has not been expanding. When filled in during the day (already hot soil conditions) then the volume that is loaded into your car is the volume after expanding, and will certainly return to its original volume when the temperature returns to normal. Automatic volume from smaller / less than the volume expansion.
•     Fill when gasoline was still at least half a tank to reduce the impact of evaporation.
•     The greater the air space in the gas tank also means greater evaporation chamber for the fuel in your tank. As much as possible to recharge before your fuel is less than half.
•     Avoid the upheaval caused by dirty fuel.
•     Do not fill the petrol tank of gas when the truck is being filled by a filler, because the fuel supply in the soil and dirt can be automatically carried turbulent ride into the tank of your car. As a result of gasoline may be contaminated dirt that harm the system in your car.

Protect Car Paint

Are you confused how to maintain the brightness of the color of your car's paint? As we've discussed in our previous articles on caring for car paint, paint the crown of all vehicles. No matter how expensive your car but if the paint faded, many scratches and cracks then your car look ugly.

There are many causes of degradation of car paint and one way to defend it is to use wax. Wax provides a protective layer which is very useful to paint the car. In addition to protecting from UV rays, a layer of wax also protects the paint from scratches, oxidan in the air, scratches and dirt.

The team did a demonstration of the benefits of SO wax layer on the surface of automobile paint. This test is performed with the following conditions:

• Wax was used Jet Wax Kit Gold Series.
• Wax is applied only on half of the hood of the car and half did not.
• Both parts are applied and which are not equally doused with water.
• First we wash the car bonnet with an air shampoo pH balanced.
• Dry bonnet (we just drain that will be applied with wax.
• Then we apply a Jet Kit Wax on the hood to the left.
• Wax is sprayed at a distance of 20-30 cm from the surface of the hood.
• Use a soft dry cloth for rubbing wax with a small circular motion. We use a cloth made of micro fiber to avoid the possibility of scratches.
• Rubbing cloth evenly on all parts to 'foam' wax look no further.
• After all the 'foam' wax look no further we spray both the hood with flowing water.
• We notice how the water is sprayed to flow down both sides.
• We note the form of granules remaining water is not flowing down on both sides.
• We notice how the remaining water droplets attached on both sides are different and easy to eliminate them.

Mineral Oil vs Synthetic Oil

Engine oil has a basic function as a lubricant to reduce friction or wear and tear of a number of components inside the machine that works and move when the vehicle engine life. Lubricants that work effectively according to its function will extend the life of the engine so that more durable lifespan.

Engine oil is also not only functions as a lubricant, but also as a coolant, anti-rust, closing the gap machines and cleaning machines. A good lubricant should be able to make a lighter engine performance and served as a protective metal component of friction due to constant friction in a long time.

From the basic ingredients, a common engine oil circulating divided 2 types, namely:

•     Mineral Oil (Base Oil): Retrieved from petroleum mining product which is processed into oil and added material to increase the quality of lubricant additives for the better.
•     Synthetic Oil (Synthetic Oil): Synthetic oil usually consists of Polyalphaolifins that comes from the cleanest part of the separation of mineral oil, namely gas. The compound is then mixed with mineral oil. This is why synthetic oil can be mixed with mineral oil and vice versa. Base is the most stable. Basically, synthetic oil is designed to produce a more effective performance than the mineral oil.

Synthetic Oil vs. Mineral Oil
Advantages compared to mineral oil synthetic oil:

•     More stable at high temperatures (less volatile) so that low levels of evaporation
•     Control / prevent the occurrence of carbon deposits on engine
•     Circulation more smoothly in the morning starting time / cold weather
•     Lubricate and coat the metal better and prevents friction between the metal which resulted in engine failure
•     Resistant to change / oxidation and therefore more durable so it is more economical and efficient
•     Reduce the occurrence of friction, increase power and cooler engine
•     Containing detergents are better for membersihkanmesin of mineral kerakOli usually made from purified while the synthetic oil from the chemical mixture.

Materials usually PAO synthetic oil (PolyAlphaOlefin). Oli synthetic is usually recommended for the latest hi-tech machinery (turbo, supercharger, DOHC, etc.) are also in need of better lubrication (racing) where the gap between parts / metal smaller / narrower / precision where only synthetic oil that can coat and flowing perfectly.

So for engines manufactured in 2001 or older are advised to use good synthetic oil-type semi-synthetic (mixed with mineral oil) or fully-synthetic.

Mineral Oil price comparison - Semi Synthetic - Full Synthetic
Fully synthetic oil price could 2X - 4X more expensive than the semi-synthetic, whereas
Semi-synthetic oil price can be 2X more expensive than mineral oil.

Diesel Engines vs Gasoline Engines

What are the benefits of diesel engines than gasoline engines? What are the benefits of gasoline engines than diesel? Which one to choose?
Both petrol and diesel engines have a distinct character that both comparisons are striking. What is certain car sales in Indonesia for petrol-engined cars are far superior to diesel-engined car with a very noticeable difference in foreign countries even though the difference is not so great. (Segment of private vehicles)

The following comparison of these two engine technologies, point-by-point:

• Vibrations (Leisure rider & passenger)

Gasoline engine is more refined than the diesel engine. This is because diesel engines use high compression mechanism in the process of combustion (higher than gasoline engines.) But the diesel engine technology is constantly becoming more sophisticated and capable of making modern diesel engine is much more subtle than the conventional diesel engine. The manufacturer of luxury cars like BMW even has developed a diesel-engine line-up.
Winner: GASOLINE

• Performance

Gasoline engines have the Horse Power (Horse Power) is greater than the Diesel engine. But Diesel engines have a greater torque especially on lap down. As a result, gasoline-engine car drivers will feel the agility of his car. As for Diesel car drivers will find it useful when I have to carry heavy loads or travel to the extreme terrain.
If you ever asked "Why there was never any gasoline-powered truck?" Now the question you already answered.
Winner: BALANCED.

• Each have advantages.

Durability (resistance / durability)
Diesel engines are well-known recalcitrant. When properly treated diesel engine can work longer than gasoline engines. It's also become a determining factor for why the machines industrial average use of diesel technology.
Winner: DIESEL

• Efficiency

Diesel engine vehicles can be said to be more efficient than diesel-engined car with a similar capacity. Not to mention if the calculated difference between the gasoline price per liter (pertamax) with diesel fuel. Indonesia issued steps Toyota Kijang Innova Diesel versions (although slightly more expensive) into a strong indication points Diesel engine technology is not owned Gasoline engine.
Winner: DIESEL

• Environmentally Friendly

Clearly superior to gasoline engines, but the presence of bio-diesel start play down these differences. But still the gasoline engine is superior, especially with the Catalytic Converter.
Winner: GASOLINE

• Conclusion

Diesel and gasoline engines have a different character. Gasoline is more dedicated in the city where the terrain is arranged neatly and the "comfortable" while Diesel was born to work hard and less comfortable. Diesel engines, however slowly but surely began to take advantage servings gasoline engines on some points above.

Birth Diesel engine line-ups in the family car a few brands that used to only "care" in the gasoline engine became terpungkiri circumstantial evidence that it was time to show off Diesel engine technology. It's not nonsense, throne "King of Diesel" from contested, even though Toyota was "not too concerned" on the black tiger.

Recognizing the Bald Tires

Beware of baldness hair, surely you would be very disturbing appearance. But if the vehicle tires bald, in addition to damaging the appearance, also lives at stake. If if you do not frequently check the condition of the tires thoroughly one-one you missed in the middle of the road.

Tires are a vital component if the vehicle going bald could endanger your life, imagine if the car lost control due to tire blow-out loss traksinya or in the middle jalan.Oleh therefore avoid the bald tires on your vehicle

Tire manufacturer has provided a special mark on each product. Usefulness of these markers is as an indicator of how worn out the tires of vehicles or so-called Tread Wear Indicator. These indicators are shaped lump that is in the tire grooves as shown in the picture.

The more widely used then the surface of the tire will be more depleted eroded by road. Well if you tire surface is lined with Tread Wear Indicator means the tire is already out of useful life.

But you also must understand the nature of the erosion on the surface of the tire. Usually erosion on the front tires are different from the rear tires. Especially in the vehicle with the driver in front (front wheel drive). To neutralize this you are advised to swap the front wheels with rear wheel every 10,000 km mileage.

There are also hair loss caused by faulty tires wheel alignment. Ban will be eroded only on one side only. This is caused by because lack of harmony between the right and left front wheels so that the distribution of load on the tire surface is uneven. When this happens you will usually feel your steering wheel as likely to walk to the left or right. If this is detected you must bring your vehicle to the service center or your garage to service spooring.

Make a check on your tires about once a month to avoid things that are not desired. If you are visiting your garage whether it's for just an oil change or routine care alone, do not forget to ask all check your tire condition. Who knows just technicians found signs of wear and tear is missed by your own.

Detecting Damage of Car Automatic Transmission

Automatic transmission on the car more vulnerable to damage than the manual transmission. That is because matic transmission is more complex. Here is the easy way as an early indication to check the condition of an automobile automatic transmission.

1. Check the condition of oil / lubricant transmission. Turn on the machine and check the transmission oil dipstick. When the oil is brown-black, and seen the iron powder is mixed in the oil means the condition is not good. It indicates that rough friction between the components therein. 
2. Testdrive and watch carefully. Move the transmission of such PRND first road going from the parking position. Do it slowly and watch carefully every movement. If you feel the beat of an excess or a slightly rough voice that has become a warning. When the car is already adopted a system of automatic transmission CVT (Continuous Variable Transmission) seharsnya movement feels very smooth.
3. Inspection by a professional workshop. If possible, take it to professional workshops. Even the available number of workshops that specialize in the service of checking and repair automatic transmissions. Certainly more accurate inspection results.
