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 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.
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.
NO ‘POLLUTION UNDER CONTROL’ CERTIFICATE? FORGET YOUR INSURANCE!
All automobile owners, please take note! The time has come when we are to take responsibility to protect our environment, whether by our choice or not. An important Court directive has been passed today.
In what has turned out to be a landmark direction with respect to environmental standards, The Supreme Court has laid down a crucial condition for vehicle owners who want to avail their regular annual insurance. Henceforth, all vehicle owners who fail to obtain the valid Pollution Under Control (PUC) Certificate from the appropriate authority will not be eligible whatsoever for availing their annual insurance. Only upon producing the PUC Certificate will they be considered for annual insurance.
ABOUT THE DIRECTIVE
After years of raising public awareness for this cause, the Environment Pollution Prevention and Control Authority had recommended the linkage of the PUC with vehicle owner’s insurance procurement. A Bench of Justices accepted the recommendation and has passed this direction with immediate effect.
The Union Ministry of Road, Transport and Highways has accepted the decision and ensured that the necessary steps to educate owners for obtaining PUC will be taken as soon as possible.
This decision has been taken also keeping in mind that hardly 20% of vehicle owners today approach Testing Centers to ensure their vehicle emission is under control. Now, with this compulsion, the Court and the authorities hope to ensure that emission is under control & vehicle owners get a sense of moral obligation as well.
ABOUT POLLUTION UNDER CONTROL (PUC) CERTIFICATE
While purchasing your new vehicle, a PUC certificate is issued, the validity of which is generally 1 year. After one year, your car will need to undergo the PUC test at periodic intervals and subsequently a new certificate will be issued to you each time. The validity of this new PUC certificate is usually six months. If in case an adverse reading is obtained in your PUC test, validity of your certificate will be decided on the basis of your current reading.
The cost of a PUC test is very minimal. It can be anywhere from Rs. 60 to Rs. 100, based on vehicle and fuel type. If any vehicle is seen exhibiting higher levels of emission than prescribed limits, its registration number will be informed to the RTO, Assistant RTO or Deputy RTO by the Testing Center within 1 day.
HOW TO OBTAIN
For your convenience, we would like to add that you can get your emission levels checked with your nearest PUC Center Affiliated Emission Center which you can locate on your Internet. These Emission Centers would give you an accreditation based on your car’s emission levels.
Using the accreditation, you can obtain your Pollution Under Control Certificate from any PUC Center near you.
Now that you have obtained your PUC Certificate, you will have no trouble in claiming your annual insurance!
So hurry and obtain that PUC Certificate as soon as possible, to avoid any hiccups in future. Save the environment as well as your pockets! We have tried to make it as clear as possible for you regarding its importance and effect. Keep reading this space for more important updates. Here’s wishing you the best of days! Happy Riding!
On Board Diagnostics refers to any vehicle’s inherent ability to register and report issues and glitches that may occur, or have occurred within the system. One of OBD’s strengths is that it can detect problems long before the driver is even able to notice any symptoms, such as low-performance, lesser economy and heavy emissions.
The OBD system functions by placing different kinds of sensors in vital areas of your vehicle, which report back to the diagnostic system whether those particular areas are working perfectly or not. When one or more sensors find a part of the vehicle that isn’t working within its designed specifications, the sensor triggers that warning light on the vehicle’s dashboard, indicating that the area needs to be addressed immediately.
There are something called as Diagnostic Trouble Codes (DTC) that are stored in the system. The codes are not the same across all vehicles. A mechanic can connect to the OBD port and diagnose the problem by reading the corresponding DTC. Let us see the various types of Diagnostic Systems.
VARIOUS TYPES OF OBD
The primary diagnostic system OBD I has certain Diagnostic Trouble Codes (DTCs) in vehicles that can usually be found without an expensive scan tool. All manufacturers can use the DTC’s to diagnose location, definitions, procedures, connectors etc. DTCs from the OBD-I cars are often read through blinking patterns of a ‘Check Engine Light’ (CEL) or ‘Service Engine Soon’ (SES) light. The ‘Check Engine’ light will output a two-digit number that corresponds to a particular error condition.
OBD II is a comprehensive update of the OBD I. The OBD-II standards specify the type of diagnostic connectors and its pin-outs as well as all the electrical signaling protocols available and the messaging format. OBD II is predominantly used by garages and pro-mechanics. However, solutions are available now for consumer use as well.
Due to it being a more holistic system, OBD-II is heavily used by all professional mechanics for diagnosing. However, there are consumer oriented products that can also take advantage of its diagnostic abilities.
Having seen these types, we must realize that unless we really derive some benefits from this system, we cannot really understand its efficiency. Let us see some key benefits of OBD.
BENEFITS OF OBD
OBD helps the technicians properly diagnose and repair complex problems.
It encourages the design of durable and robust engine optimization systems.
Exhaust Emissions can regulated by identifying the emission controls in need of repair and also provides for effective/inexpensive emission inspections.
It generally works for life of the vehicle.
Early detection of malfunctions to prevent secondary malfunctions (e.g., detect misfire before catalyst damaged).
Fault codes are given out by the system that can be negated Apart from this it can provide vital data about area of malfunction or the specific component where attention is required.
The OBD process consists of four simple steps that is carried out by the system in aid to diagnose the issues.
THE PROCESS OF OBD:
Your system continuously monitors and assesses operating conditions.
It observes the signals entering the computer directly from the component/system, or related to the performance of the component/system.
It then verifies the performance / functionality / rationality of the malfunction criteria.
It finally notifies the driver of the particular fault by the illumination of warning indicator or stores the unique fault code and throws up an error on the instrument panel.
IMPACT OF OBD ON MULTI-BRAND GARAGE SERVICES
It is easy to make the assumption that a Toyota service center can diagnose a Toyota car to perfection, that being its product. However, the same is not easy to do for a multi brand garage as they spend more time to even diagnose the issue. An authorized service center of a brand would have no trouble in diagnosis simply because they built the cars they have to service. The same is not the case for multi brand garages which have to fulfill multiple demands. This is where the On Board Diagnostic System proves to be a huge boon. As shown in the benefits of OBD, it can prove a life-saver for garages servicing multi brand cars. Their technicians just have to combine their expertise with an apt reading of the OBD codes to diagnose the problems. This in turn leads to faster checkout of serviced vehicles, easier diagnosis and better quality of service rendered.

Petrol Vs Diesel Cars in India 2016 – Which is better?
Cars have become a common itinerary in the wish-list of the middle class population of today’s cities. But it is a common problem with the general mass on choosing between the petrol and diesel variants of a car. Getting opinions of the near and dear ones might seem confusing rather than enlightening, and so here is a guide to choosing your dream vehicle.
Before giving the titbits, there are certain considerations that have been taken into account.
The inferences have been arrived at by considering the pocket of a normal middle class person in India, who plans to buy a car.
The car models have been decided by the prevalence in Chennai city and its suburbs.
The numeric values are based on the current trends in the Indian market (that is, considering May 2016)
Price of the car:
This would vary depending upon the buying capacity of the consumer. But for Chennai, or in general, India’s traffic, a 4-seater hatchback in the bracket of 5 to 7.5 lakhs would be the affordable choice for everyone. Moreover, the cost difference between the petrol and diesel variants which is about 60,000 to 1 lakh INR for the cars below 8 lakh levels tend to increase as we increase it beyond 10 lakhs. For ultra-modern, savvy cars that cost around 25 lakhs, the price difference is generally around 1.7 lakhs to 2.5 lakhs.
Diesel variants usually cost more than the petrol ones because of the former’s enhanced efficiency aspects.
Distance traveled per day:
The daily sojourn comes into consideration here along with a few other extra trips that one would make periodically in his/her car. The routine travails imply the distance covered by an office-goer from home, from the taxi depot to the designated stand in case of a taxi, etc. The other trips include weekend visits to picnic spots and unexpected emergency situations.
Cost of petrol vs diesel per litre :
Before the government deregularization came into existence, the price of diesel used to be as much as 16 to 20 rupees lesser than that of petrol in the subcontinent. But now, the margin has come down to a maximum of 13 to 15 bucks. This is one important aspect that needs to be considered along with the general price bracket of the car.
Mileage of the car:
The ideal mileage specified would have certain condition attached to them.The mileage specified cannot be achieved at any point during city drives, where intense traffic is the common scenario throughout the day. Mileage would also depend on the quantity of load that the car needs to carry other than the kerb weight (the weight of the car with no load) and the other external factors like optimum usage, smooth driving and efficient, serviced components. Increase your car mileage by following these 8 simple tips.
Petrol vs Diesel Cars In India Case study:
Since an aam aadmi would opt for the price range between 5 lakh and 7.5 lakh INR, let us assume 6 lakhs to be the cost of a car X. Considering Chennai city, a person would normally travel around 40 kilometres on an average (the to and from distance between Adyar and Tambaram, approximately) to his workplace and back.
(All the quantities detailed below are arrived after considering most of the cars in the price range, and they may not be exactly specific or accurate, as they do not point out to any particular brand or model)
Cost of petrol = INR 62 per litre
Cost of diesel = INR 53 per litre
Mileage of the petrol variant = 20 kmpl
Mileage of the diesel variant = 24 kmpl
This would mean that for a person travelling 40 kilometers daily, 2 liters of petrol or 1.7 liters of diesel are required.
Cost for petrol per day = 62 * 2 = INR 124
Cost of diesel per day = 53 * 1.7 = INR 90
This would mean that the daily savings by driving a diesel vehicle is around 35 bucks for the above mentioned case.
Now let us take into account that this person has to travel to his workplace for 25 days in a month, 35 * 25 = 875 bucks a month.
(Note that no extra travel is taken into account in this case)
If there are going to be some other travels as discussed at the beginning, let us take this as around 200 kilometers for a month. So if 35 bucks is the savings for 40 kilometers, it is 175 rupees for 200 kms.
So overall price saving due to diesel vehicle = 875 + 175 = INR 1,050 per month
For a year, this is 1,050 *12 = INR 12,600
Now consider the extra buck you have to pay when you are buying the diesel variant, say INR 80,000.
Payback period = 80000/12600 = 6.35 years
This would approximately mean 6 years and 4 months. If the car is purchased in loans or EMIs, the interest amounts need to be added up which would add a year more. So for a common man (who would buy the car only through installments or loans), it would around 7 ½ years to repay the initial costs, provided the above mentioned conditions are satisfied.
This would get reduced if the person travels around 60 to 70 kilometers per day in the diesel variant (the payback period would come down by almost two years). But there are other factors that are needed to be addressed in petrol and diesel cars .
The NVH (noise, vibration and harshness) is more in diesel vehicles than that of petrol generally. And hence the maintenance cost is high for the diesel car owners. So for long-term benefits (say 7 to 10 years), diesel vehicles can be deemed fit. But if you are looking at it in the point of view of around 3 to 5 years, petrol variant would sound a good choice.
