Constant vehicle, save fuel

You may often see the drivers that often spur vehicle in high speed, of course, on the grounds that quickly reached the destination? But did you know that the vehicle is driven in speed above the average automobile fuel can drain faster than it should, not to mention the risk of accidents to be borne? To overcome the risk of wasteful gasoline, WHEELS teams provide some tips that might benefit you.

The first step (this is quite difficult, especially for those who have the soul of the drivers) is to maintain the vehicle speed remains constant. Each time to shift gears, get the RPM range so that the car is in the numbers 3000 - 4000 (for gasoline vehicles) and 2500-3500 (for a diesel). That way, gasoline / diesel fuel used as a primary energy resource to run the vehicle also 'burned' by a constant amount.



For the uphill road, the speed and the above is mainly to watch. While for the downhill, the braking / brake usage should also be constant in maintaining vehicle speed. Who stepped on the brakes must be balanced, and keep that RPM does not exceed the specified limit (one way is to move the gears). In addition, play your car in gear so that the speed and the rate constant RPM.



The last step is in the open car windows. Often times in the course of near and far (especially when the car is not equipped with refrigeration equipment), we open car window so that cool air to flow inside. But make no mistake, should be opened, try to not just one but both sides (left and right) window is opened. Because if you only open one side only, the air circulation will only run in one direction (incoming) and thus would hamper the speed of the vehicle.Automatic, more fuel will be drained.

Preserved Despite Rarely Used Cars

Perhaps you are one of the people who are very busy, the task force to travel frequently out of town or the country in the long term. If you have a private car, it should be noted that when it returns later, the vehicle is not in the condition of abandoned or pathetic. The first step you should do is wash the car before it was abandoned. Then, follow these tips.

1. The position of the handbrake released

If left in a state of emergency brake in, especially in a long time, will happen with the adhesiveness between the oil disc brakes, especially for a vehicle that has a drum on the rear wheels. One additional thing, it helps your car keys let it hang on the wheel of your vehicle. If your house has a maid, it would be useful to heat the vehicle every day. But do not leave your car keys when you did not have a garage or out in the open.


2. Wiper with a foam wedge / wood
When kept in contact with the windshield, wiper rubber will slowly harden and no longer pliable. As a result of the rubber (the so-called dead rubber) will feel rough when later used to wash your windshield.


3. Keep all four tires in a raised condition is not stick to the floor
Way, simply by using a jack and jack stand.
The goal is to ensure that the car's suspension is awake and not burdened by the weight of the vehicle. A car that was never used in a long time suspension will usually go up and down, so that when used later, the car will feel uncomfortable.
 

4. Remove the battery if the car was left more than two weeks
Why? The reason is that car batteries are very sensitive. If the vehicle is turned on at all in two weeks or more (especially when in the house that you leave no maid), it will affect The battery, which can be more easily damaged than the vehicles used daily.


5. When the parking lot side, prop your four tires beam
This goes for those who have a garage with a sloping surface. In the first tips that are not mentioned either put the hand brake position when the vehicle left long enough, but how if the surface is tilted? It's easy, just chock all four tires with blocks or other hard objects so that the car has not changed position.
 

6. Put the car deodorizers, and close the car with the cover
Fragrances serves to neutralize the musty smell that may arise because the space in a closed car in a long time. In addition, the car is left in the open state also allows dust particles to enter the car through the cracks, something that is certainly not desired by any car owner. To avoid this, simply buy a car cover is usually sold in car accessory shops.

The first thing to note is that the car electrical system, conventional or modern cars are already using CDI (in the sense of all-electronic). If your car has been using all-electronic system, do not try to fix it manually because the system requires a reliable mechanic and equipment only
in car garages.

Usually there are two things that cause a car to the starter, the first is that the battery is in good condition less electrical system. The second is due to supply electricity to the armature in a conventional ignition system. Platinum may be not good. If the technology is more advanced, perhaps because of CDI. Kalou already CDI problem, perluke workshop because already complicated and difficult to handle alone. On the upper surface of the battery there are indicators that show the last condition of the battery. Can nunjukkin good battery condition / damaged, or an empty battery water.

For info about The Rubber Round commonly known by the name of the tire, peel out. There are a few tips that are present on how to treat Ban to stay comfortable and durable.  

Tips are:

1. Tire sizes and tread patterns must match. Minimal on a single brand as well as having the same characteristics.

2. Use tires with the same construction (eg from Polyester material or steel).

3. Tubles tires to be mounted on a rim that is specific to tubles tires. And vice versa. Since this type of tire using an inner tube, but using the rim tubeles, will result in reduced air pressure. While if you choose to use a tire type tubles, do not force it to use the inner tube. Because the high-speed hot air in the tires will quickly rise The round rubber and the effect is explosive at any time.

4. Fitting the tires should be tailored to the type the outer tire. And if possible, use a tire within the same brand with the outer tire.

5. Note also the condition of tires you use on your vehicle.How to recognize the condition of the rubber round so easily. Recognize The Rubber Round by looking at the instructions TWI (Thread Wear Indocator). Make figures as a benchmark measure of the TWI. Afterward, you try to measure the thickness of the wheel tracks with a ruler from the bottom of the groove. If less than 2 mm you should immediately replace your tires with new ones.

Tips above, of course beneficial to you. But there are certainly less so among you who understand the characteristics of the tires sold in the market.

2. Figures 65 R is an indication of the height of the tire measured from rim to tire cross-section stick to the road. The bigger the number the more too thick tire wall when viewed from outer side (if measured from the rim).

3. Figures 92 and H show the minimum speed is also Maximum tire. The larger the numbers tingkatakn demonstrated the greater the strength of the tire a certain speed.

For the last number mentioned there is little explanation. In the world of The Rubber Round, the manufacturers usually include code standardization tire speed. There are several classification rate specified in each type of tire, the classification is:

1. TR tires of this type can be used to speed vehicle about 100 Km / h.

2. HR tires of this type can be used for vehicles traveling at 210 Km / h.

3. VR tires of this type can be used on vehicles capable of driving at a speed of 260 km / h

4. ZR code indicates that the tires of this type can Used vehicles are capable of traveling at keceparan 340 km / h.
