HIGH FUEL CONSUMPTION

Whether we’re fleet managers or private vehicle owners, we’ve all dreaded driving into the petrol station at some point. Or even on multiple occasions because we know that money will leave our pockets for every drop filling our tanks. High fuel consumption in petrol engines is caused by many factors, but I'm going discuss on one of the major factors which is LAMBDA SENSOR

WHAT IS LAMBDA SENSOR
Is a measuring probe that monitors the car’s air-to-fuel ratio and relays the information to the car’s ECU (engine control unit). The ECU can then regulate the air and fuel mixture so that your car runs as cleanly and efficiently as possible.

It also plays an important role in controlling Emission systems in our cars—making them not only better for the environment, but easier on your wallet by improving fuel efficiency.

TYPES OF LAMBDA SENSOR
(1) Binary lambda sensor
(2) Universal lamda sensor

The binary sensor generates a change in electric voltage depending on the oxygen level in the exhaust. It compares the residual oxygen content in the exhaust with the oxygen level of the ambient air and identifies the transition from a rich mixture (lack of air) to a lean mixture (excess air) and vice versa.

The universal lambda sensor is extremely accurate when measuring both a rich and lean air/fuel ratio. It has a greater measuring range and is also suitable for use in diesel and gas engines.

SYMPTOMS OF FAULTY LAMBDA SENSOR
Like any car part, lambda sensors have a limited life span. Things like soot buildup, oil, salt, dirt, or contaminated fuel can all lead to them failing early.

There’s a few common symptoms that can point to a faulty oxygen sensor, so let’s take a look at them:

(a) High fuel consumption
(b) Rotten egg smell (rich mixture)
(c) Poor fuel economy (rich mixture)
(d) Black smoke from exhaust (rich mixture)
(e) Engine misfires/rough idle (lean mixture)
(f) Engine stalling (lean mixture)
(g) Trouble starting your car (lean mixture)
(h) Check engine light comes on

If you leave it too long, a faulty oxygen sensor can lead to problems with fuel economy and efficiency, as well as causing engine damage.

WHAT TO DO WHEN THIS SENSOR IS BAD

1. Get a Diagnostic Scan
Use an OBD-II scanner: Connect a scanner to your vehicle's diagnostic port to read the error codes.
Confirm the fault: The codes will indicate a test failure, not necessarily a specific faulty part. Use the scanner to check live data and compare the readings from the suspect sensor to a known working one to confirm the sensor itself is faulty.

2. Replace the Sensor
Do not drive the car: A bad lambda sensor causes improper fuel-air mixtures, which can lead to poor fuel economy and potentially damage the catalytic converter.

3. Clear the error codes: After replacing the sensor, use the scanner to clear the codes and ensure the check engine light is off.

Learn Your Vehicle’s Warning Lights
No one likes seeing a warning light turn on. It could turn a simple spin around town into a stressful drive home. That's why you should learn what each warning light means and what to do when one is on.

Tell me something about routine maintenance?

NOTE:-
Routine vehicle maintenance refers to the regular checks, inspections, and servicing that are performed to keep a car in good working order and prevent future issues. It's a proactive approach to car care, involving tasks like oil changes, brake inspections, tire rotations, and fluid top-ups, which help avoid costly repairs and breakdowns.

NOTE THIS
Driving your car during raining season can be one of the toughest challenges facing you. If you drive fast there would be a chance of skidding and accidents. Rainy conditions are directly associated with higher accident rates.

Here are a few tips to take into consideration when driving your car during raining season:-

(1) Check your tires:
Make sure that your car tires are in perfect condition before taking them out of your car during raining season.

(2) Water Logged Roads:
While driving on water logged roads ensure that you are not going deep in the water. Try to estimate the level of water logged on the road before entering the area. If you drive when the water level is high, water may enter the car and cause damage to the car engine and other parts beyond repair (sometimes).

(3) Drive Slow:
Remember the quote “Slow and steady wins the race” which is very much apt for drivers riding cars in the rainy season. While driving on the wet road it is important to remember that driving slowly can prevent accidents.

(4) Windshield Wipers:
Some people neglect to maintain their windshield wipers in working condition which will affect them seriously while driving during raining season.

(5) Check your headlights and taillights:
Your headlights and taillights are more important than ever during the rainy season not just for illuminating the environment when it's dark and stormy but also to indicate your position clearly to other road users.

Conclusion:
Maintaining a car properly during raining season is important but it's also important to drive carefully, and not just rely on the mechanical aspects of your car. Avoid these areas when it rains and make sure you drive at a reduced speed.

If you are running on a tight budget, fuel consumption must have been a concern for you. If you are not careful, poor fuel consumption can cost you a lot of money. Keeping a check of some key aspects can help you in drastically improving the fuel consumption of your car.

If your car is not returning the expected fuel consumption, do check the following points to figure out what can be a possible problem.

(1) POOR QUALITY ENGINE OIL
Viscosity grade of engine oil is something that you have to keep in mind before buying engine oil for your car. Using the wrong motor oil for your car can lead to greater fuel consumption.

(2) BAD CONDITION OF TIRES
Old tires lose their traction on the road, and they have to spin more to maintain a certain speed. This consumes more fuel than necessary. Low tire pressure can also lead to more fuel consumption.

(3) POOR MAINTENANCE
Delayed and poor servicing of your car can lead to higher fuel consumption.

(4) SHORT DISTANCES
Cars consume most fuel at the start of the journey when it is not warmed up and on short trips. Make sure when you are going out, you get done with the maximum amount of your chores.

(5) FAULTY ENGINE
If your car’s engine is not tuned properly and has not been serviced on time, this will ultimately make it use more fuel than required.

(6) POOR QUALITY FUEL
Always try to get fuel for your car from a renowned fuel station. Bad quality fuel will take longer and will require larger quantities to power the engine. This will also increase the accumulation of waste after the burning of the fuel in the intake valves and injector nozzles.

(7) DRIVING IN A WRONG GEAR
Every gear has a speed limit, and this must be observed cautiously.

(8) POOR CLUTCH CONDITION
When your car’s clutch is in poor conditions, slippage occurs, which is the reduced contact between the pressure plate and the clutch.

(9) NOT WARMING UP VEHICLE
This holds true especially in winters and colder climates. Whenever you start your car in the morning, let it stand idle for a while before driving it. .

(10) OVER SPEEDING, OVER LOADING, AND AIR CONDITIONING
Over speeding always puts a strain on the engine as it has to work hard. This results in more fuel consumption than driving at normal speeds. Generally, in normal cars, speeds above 120 km/h result in fuel wastage. Similarly, overloading also puts undue pressure on the engine. In order to propel the added weight, the engine must work harder to produce more power; therefore, using more fuel in the process.

If you are driving with air conditioning turned on, the engine surely consumes more fuel. However, if you are driving at higher speeds, turning on the air conditioning might result in better fuel economy compared to opening up the window. This is because the latter creates aerodynamic drag, which reduces fuel efficiency.
