Have a sudden high fuel consumption oF your car? Lets discuss the common problem or causes of high fuel consumption instead of driving style. We try to know the technical problem that contribute to high fuel consumption.
Fuel efficiency, is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. We can increase the fuel efficiency by maintaning the car to the optimum setting.
-CAUSES OF HIGH FUEL CONSUMPTION
The causes of high fuel consumption would be:
+ air intake : This will cover the cleanliness of carburetor or throttle body and the air filter. Make sure there is no obstruction in the air intake system and no carbon deposits or dirt. This is the most important part to get better air flow and fuel consumption.
+ tyres : Inflate your tyres regularly to make sure the tyres are inflated within the limits. If possible, inflate it with nitrogen due to its good property that will retain longer in the tyre and is lighter.
+ spark plug : Check your spark plug at several interval for wear or carbon deposit. Change it when it reaches 40,000km – 50,000km.
+ tuning : Tune your engine to get optimum fuel consumption. Tuning is very important to have a complete combustion.
+ Faulty O2 sensor : This sensor got wear & tear also and expected life is abt 50,000km to 100,000km. when the sensor starts to die, it usually signal low voltage to the ecu and ecu automatically keeps adding fuel to yr engine.
+ sport rims : SOme sport rims is heavier than the standard rims. This will cause higher fuel consumption of you car.
+ fuel filter : Clogged fuel filter also can cause high fuel consumption.
+ Injectors : can spoil or get dirty. Go to service center to clean it.
+ brake caliper : brake calipers also need servicing.. if too much dirt and debris get stuck to the brake pistons, it can get jam.. thats when ur engine have to work hard to push the extra load created by the braking. jack car up and roll wheels to check
+ insufficient engine grounding : Many people didnt realize how important engine grounding is. The grounding cable which costs around RM100 with the voltage stabilizer will make so much different on your car performance and fuel consumption. It is highly recommended that you install the device.
+ faulty MAP sensor: Faulty map sensor creates inconsistent signals to engine ecu and results in inconsistent a/f ratio..
(OPTIMUM SPEED FOR BEST FUEL CONSUMPTION IS BETWEEN 80-95 kmh)
Any other causes of high fuel consumption? Kindly share here.
You basically got it all covered..haha.
Two more to think about:
+ Winding down the window for a puff causes drag, therefore not only our lungs koyak but the FC as well.
+ Using wrong exhaust extractor and piping size, and putting in a straight flow instead of the stock S-flow piping.
FUEL PRICE INCREASE! This article came in at the right time, it’ll make us more aware now about FC.
+ RON95 petrol price will increase by RM0.05 to RM1.85.
+ RON97 petrol will be put on a ‘controlled float’. Maybe RM0.05 to RM2.10 per liter or will it go up by a larger margin.
+ Sugar will go up by RM0.25 per kg to RM1.75…so TT will be more expensive NOW!
Seriously, the government has implemented some kind of incremental subsidy reduction plan similar to Idris Jala’s proposed PEMANDU plan..F@#$%^&..so watch out closely your FC now!
faktor kereta yg menentukn penggunaan mnyk….
klau diservis mngikut jadual sistem akn berjalan ngn lancar….
kapasiti enjin gak de kaitan dan kecanggihan teknologi sesebuah kereta e2…….
tp sejimat mane kenderaan e2….cara pemanduan yg jd faktor utama….
Kene bookmark page nih..penting2x
pemanduan di bandar (banyak hentian) lebih makan minyak berbanding lebuhraya. ini semua pun tahu kan. hehe.
teori disebaliknya adalah, akibat banyak hentian kereta perlu menggunakan tenaga yang banyak untuk memulakan semula pergerakan kereta, ini menyebabkan banyak tenaga dipakai.
oleh yang demikian, elakkan berada dalam situasi kesesakan lalulintas, gunakan lah lebuhraya, jadi pengguna yang bijak. haaa
bro khairil
kdg tu tak semua tpt boleh g guna h/way, kena laluan bandar juga, so kena plan perjalanan katakan g point A,B,C jgn lah g point Z,R,A,L
ya betul tuan, cuma kalau ada alternatif lah. hehe
ok
bateri kena jaga juga pastikan sentiasa berada di atas 12.4V, penting utk sensor2 danalat elektronik lain yg mengawal pancitan bhnapi.
so gunakan lah VS, tak pun VS DIY sbb bateri keta saya dah 9 bulan lebih ttp masih maintain 12.687V
Gn GPS pn bley mmbantu dlm mndptkn plan perjalanan yg lebey pendek dan pantas..
Jimat minyak..
walauapapun, cara pemanduan dan penyelenggaraan kenderaan juga yg terpenting utk diambil tindakan.
i think O2 sensor is important.i raed that EFIE will help much,but where to get it?anyone know?sometimes we didnt notice that our car are in poisonous position cause by exaust gas
Buang sampah yang terkumpul dalam kereta mislan botol minuman, surat khabar lama, buku lama, resit lama dll
