Hybrid Cars

What is a hybrid car?
Hybrid cars are electrified vehicles that still use an internal combustion engine, which means combining a petrol or diesel engine with an electric motor. The main advantage of a hybrid is that it consumes less fuel and emits less CO2 than a conventional petrol or diesel-engine vehicle.

How do hybrid cars work?
Driving a hybrid is similar to driving an automatic car, so there’s little compromise on performance. A hybrid combines at least one electric motor with a gasoline engine to move the car, and its system recaptures energy via regenerative braking. Unlike an Electric Vehicle (EV) or Battery Electric Vehicle (BEV), hybrids also have a petrol or diesel engine to fall back on if the electricity supply is diminishing.

Types of hybrids:
There are three different types of hybrids and each work in a different way.

Parallel/Full Hybrid
This is the most common type of hybrid. A full hybrid is a car which can drive under its own electric power, petrol or a combination of both. They are sometimes called ‘parallel hybrids’. The car’s wheels can be powered in three different ways: either directly by the engine, by the electric motor alone, or a blend of the two power sources. The Toyota Prius is the most widely known example.

Mild Hybrid
A mild hybrid car cannot drive under electric power alone and doesn’t improve fuel economy to the extent that a full hybrid system can. The engine never drives the car; it only produces energy for the electric motor. The Honda Jazz r is one of the more popular examples.

Plug-in Hybrid
As its name states, this type of hybrid can be plugged into an electric outlet to recharge their batteries, as well as being charged on the move. It carries a much larger battery pack that must be fully recharged using an external electricity source from the home or public charging station. Popular plug-in hybrids include the BMW i8 and VW Golf GTE, with both cars having bigger battery capacities to enable a longer electric range.

Tips to Minimize Wear and Tear on Your Car

Preventative care, careful driving and regular maintenance all contribute to your car’s longevity, making it stay longer on the roads than in a garage. Proper care also helps you save a lot of money in the long run. Here are a few tips on how to make sure the wear and tear in your car is minimized.

Stick to your maintenance routine:
Familiarize yourself with your car’s maintenance schedule and stick to it. As your car age, more maintenance is required and car manufacturers always recommend regular service intervals. If you don’t do a regular service on your car, you run the risk of causing damage to your engine and other parts because service centres know what needs to be checked and replaced with time, such as spark plugs, oil, filters, etc.

Never miss an oil change:
Oil is the lifeblood of your engine and over time the motor oil begins to degrade and lose its lubricating and cooling properties potentially damaging metal-on-metal contact. Regularly changing your oil and filter can save you in the long run, the failure of which could have you replacing your whole engine!

Warm-up!
Everyone is always in a hurry and it’s not uncommon to want to jump into our cars and rush off. But experts recommend that it is important to give your engine a minute or two to warm up. This helps your engine oil heat up and lubricate all the parts. It’s also best to avoid higher RPMs and speeds until the engine is properly warmed up and running at normal temperature.

Give your brakes a break:
Prolong the life of your brake pads and discs by easing up on constantly using them. The safest way to do it is by slowing down. The faster you drive, the more you will need to step on the brakes sharply. Keep a safe distance between the vehicle in front of you, which will give you more time to come to a slower stop without having to jam on the brakes often.

Use the parking brake:
A better option is to engage the parking brake when you stop. First, step on your brake pedal and then engage your parking brake; put the car into park and release your foot off the pedal. This will prolong your car’s transmission allowing the parking brake to take the car’s weight and not the transmission.

Minding Your Mileage

In the current trend in India, gold rate as well as fuel rate increases randomly! The thing is we cannot control gold rate, but we can maintain our car’s mileage by maintaining it in good shape; regular service of your vehicle can increase its mileage and durability.

Yes, idling is bad:

Idling is a common mistake which we all do while driving. If you’re a passionate and experienced driver, you are keen on driving. But for beginners, it’s very common for them to leave their vehicle idling. There are many ways to avoid idling: you can warm up your engine by driving it at a moderate speed instead of idling it. You can also turn off your ignition when you’re waiting more than 15 seconds. Warm up the cabin interior by driving, not by idling. Lesser idling also protects your car engine.

Don’t stress your engine:

We should switch gears according to speed, because if you’re driving at 40kph on the fourth gear, you will notice a slight wobbling inside the car. This is due to wrong shifting of the gear; on the fourth gear, you should at least drive above 80kph. So if you’re driving with proper gear shifting according to your speed, you will improve your fuel efficiency and lessen your engine trouble as well. If you’re using an automatic, make sure overdrive is on.

Proper Acceleration:

Some of us usually pedal it freely as soon as they start their vehicle, and the same is followed at traffic lights; as we’ve seen and done numerous times, as soon as the traffic light turns yellow, we put the pedal to the metal immediately like a racer and if you have to stop abruptly, high fuel consumption and energy is wasted to stop your car. So we should be aware to pedal softly depending on the situation and more importantly, for safety!

Inflate the tyres:

For better mileage, one of the easiest things to do is to inflate your tyres at the correct pressure. As long as the wheels turn well and the tyres maintain good contact and friction with the ground, tyre pressure is often overlooked. Tyres with correct pressure levels helps you get good rolling resistance and better mileage.

Don’t Ignore These 5 Car Engine Noises

Every car comes with some metal parts in the exterior, and fibre in the interior. It is very common for these parts to start producing noises over years of use, largely because of vehicle usage.

Engine knocking sounds:
This is heard when you drive your car by changing gears or by acceleration. It is caused because the early ignition of the air-fuel mixture has not produced the minimum power at the right time. In this case, check your engine oil level. If you find any faults, take it to your nearest service centre. Sometimes proper tuning of the engine could fix this issue.

Pinging on cold start:
This noise is caused by the fuel mixture in the engine cylinder being ignited too early by the heat of compression. We can hear this noise during acceleration of the vehicle. As the engine gets older, it will start to ping more on cold start.

Tapping sound from the engine:
The tapping sound from the engine is due to the low oil level or loose components. You can check your oil level using the dipstick. When you rev, the engine tends to produce more tap or upper valve train noises.

Loud squealing:
Loud squealing noises come from the internal engine and is caused by the belts. In a car, there are multiple belts: one for power steering pulley and one for the AC compressor. The belts generally slip from the pulley because it’s worn out. This sound is louder when you start the engine cold and fades away as you accelerate.

Grinding noise:
This is one of the common engine noises heard frequently. This noise is caused by the driver when shifting the gears; because when you apply the gear with half clutch, then there will be a grinding noise. If you are doing so, avoid it because it can damage the entire engine system.

Check the oil level regularly; because in a car, noises arise primarily because of the low level of oil. The other common thing is a bad belt, which can cause squealing noises. If you find worn-out belts, it’s time to replace them.
