Fuel consumption is one factor that is taken into account in driving. Moreover, the price often increases every year, plus the level of road congestion which also continues to increase. These two things then make some vehicle users switch to vehicles that are comfortable in the bag, aka economical fuel.
Indeed, currently car manufacturers, especially in Indonesia, are increasingly concerned to make and market cars with economical fuel consumption. However, these cars are because they are designed to save fuel so that energy and acceleration capabilities can be considered boyot. This certainly reduces the driving experience, especially for speed worshipers. At a time when the road is rather quiet and we want to be a little streaking, of course we will be disappointed with the performance of these fuel-efficient cars.
Then how can we continue to save on fuel without having to ‘be forced’ to switch to fuel efficient cars?
In this review of driving techniques , we will discuss ways to save fuel consumption by using hypermiling techniques.
By using this technique, we can make cars with large engine capacity so that they are not too often ‘thirsty’. As for cars that are already economical, it will certainly become even more economical.
Hypermiling: The technique of saving fuel
Hypermiling is a technique to increase the amount of mileage for each liter of fuel used. So for example the fuel consumption of our car is 1: 8, which means 1 liter of fuel for a distance of 8 km. Now, with the hypermiling technique we will increase consumption to 1:10 or even more. The hypermiling technique uses a number of methods or strategies that involve driving behavior and vehicle efficiency.
Although this technique sounds simple at first glance, hypermiling is actually quite complex. Even so, it actually makes hypermiling an interesting (and also useful) technique to learn, especially for fans of hypermiling called hypermilers.
How to do Hypermiling
As mentioned before the hypermiling technique covers quite a few aspects as a whole. So this technique can be called a collection of ways, tips, tricks or techniques to maximize vehicle fuel efficiency.
Hypermiling is done in the following ways.
Prepare the vehicle
The initial step for hypermiling is to make sure the vehicle can work as efficiently as possible. In other words, we must make the vehicle in the best performance to be able to save on fuel consumption. This is done in the following steps.
- Make sure the vehicle has got a good maintenance service. Even better if the vehicle is tune-up periodically. Poorly maintained vehicles will not work optimally and fuel consumption will become less efficient.
- Car tires are the ‘legs’ of the car. Therefore, make sure the car tires are still in good condition. Also check and ensure tire pressure so the vehicle can work optimally and efficiently.
- If the vehicle has several choices of oil recommendations from the manufacturer, choose the oil with the lowest viscosity. This oil can make the engine work lighter so that its performance will be more efficient. However, the thinner oil is not as good as thick oil when it comes to protecting engine components. So this option can be abandoned if we want the machine to last longer.
- Reduce the burden on the car by removing unnecessary items in the car. According to the research results, each additional load of 45 kg will increase fuel consumption by 2%.
- Hypermiling will require a clear view. Therefore, make sure the lights and headlamps are working properly.
- Record the odometer to monitor our fuel consumption ratio.
Driving a car
After the vehicle is ready to use, it’s time to depart and practice other hypermiling techniques. The technique or methods are as follows.
- The main philosophy of driving a car with hypermiling is to use the gas pedal and brakes to a minimum. Every time we press the accelerator, we use fuel. Every time we press the brake pedal, we waste energy from the fuel. Thus, the use of these two pedals must be strictly maintained to be as effective as possible.
- Keep the car moving at an efficient speed. This is different in every car but generally ranges from 56-80 km / h. Above 96km / h, each additional 8km / h will reduce efficiency by 10%.
- Press the accelerator slowly and immediately lift if we see obstacles in front of the road such as red lights, the car stops and so on. Let the car ngagorolong (roll) until we are sure to continue pressing the gas pedal again. The term to release the car to roll is called coasting. The technique of pressing the gas pedal slowly and then releasing the gas pedal for coasting is called the pulse and glide technique .
- When driving, always concentrate and maintain your foresight. Pay attention and take into account what is ahead such as a red light, a vehicle that stops or crossing the road. For example in front there is a red light, then release or relax the gas and let the vehicle roll toward the red light. Going normally then braking when it is clear in front there is a red light will waste fuel.
- Watch the rise and fall of the road. In derivative conditions, then immediately release the gas and put the gear into normal or press the clutch fully. In this condition always prepare your feet to brake, because the car will glide freely. When climbing, the most efficient way to save fuel is to drive slowly using low gear. Driving normally let alone fast on a ramp will suck up a lot of fuel.
- Do drafting. Drafting is driving behind (trailing) larger vehicles so as to reduce air resistance because the car is blocked. Research shows air resistance is reduced by 90% for cars that go 3 meters behind a small truck. Increased efficiency was quite large, namely in the range of 20-40%.
- Turn off the car air conditioner because it clearly increases the fuel consumption. If indeed we have to use AC because of the hot road conditions, then do cycling by turning AC on / off. Do not leave the air conditioner on. Turn off the air conditioner when the car and body feel cold. When it starts to feel warm, then turn on the air conditioner again.
- Avoid idling. A car that lights up without going (idle) is just wasting fuel. When starting the car, don’t let the car idle for too long. But go slowly for 5-10 minutes. In road conditions that are very congested, rather than leaving the car idle for more than 10 minutes it is better to just turn off the car engine. Idle cars consume 1 liter of fuel for every hour.
Other Tips on Hypermiling
- Use footwear that is not too thick so we can feel the pressure of the gas pedal well. Hypermilers often take off their shoes and only use socks or barefoot when driving.
- Hypermiling can sometimes ‘irritate’ other drivers, especially those driving fast. Therefore drive on the left side of the road and close to the shoulder of the road.
- Some of the techniques in hypermiling that have been mentioned such as drafting or coasting can increase the risk of accidents. Therefore be careful and always maintain concentration.
