Car Care 101: Lubricating Your Car Engine

Oil lubrication is vital to vehicle engine system
such that it provides a barrier between rotating
engine parts to prevent damage by friction,
damage which can result in huge auto repair
bills. The engine lubrication system includes the
oil pump, oil filter, lubricating oil and the oil
passages. The engine oil provides a method of
cooling engine parts that are not cooled by the
engine cooling system. Engine oil helps to
protect engine components from corrosion by
neutralizing harmful chemicals that are the by-
product of combustion.
To protect moving parts and reduce friction,
automotive engine oil provides a barrier
between the rotating or moving engine
components. Ideally, a film of oil should
exist between moving components. This is
called full film lubrication. In order to
achieve full film lubrication, a constant
supply of clean oil is required. The engine
oil system constantly filters and circulates
engine oil to ensure that all components are
protected.
The engine oil is stored in the crankcase. Most
engines hold between 4 to 6 quarts of oil. The
engine oil pump pressurizes and circulates the
engine oil.
The oil will flow from the OIL PUMP to the OIL
FILTER , where it is cleaned. The cleaned engine
oil then moves through passages, into the
CRANKSHAFT where it circulates through the
engine bearings. The crankshaft has passages
bored into it that allows oil to travel to all the
bearing surfaces. The CYLINDER WALLS and
PISTONS are lubricated by the oil that is thrown
from the CRANKSHAFT as it rotates. This is
sometimes referred to as SPLASH LUBRICATION.
Engine oil will leave the CRANKSHAFT, usually at
a passage in one of the main bearings and is fed
to the CAMSHAFT and LIFTERS . On some
overhead valve engines, oil will travel through the
PUSHRODS up to the VALVE TRAIN to lubricate
the rocker arms. Other designs use a passage to
feed oil through a ROCKER ARM shaft to achieve
the same purpose. The oil then returns to the
CRANKCASE by return holes in the cylinder
heads. It is then picked up by the OIL PUMP to
be circulated again.
This process is more or less like a circular
movement ::> From the OIL PUMP to the OIL FILTER to
the CRANKSHAFT to the CAMSHAFT/LIFTERS to
the VALVE TRAIN to the CRANKCASE then back to
the OIL PUMP .
To be continued...

Tips & Advice: What Is A VIN (Vehicle Identification Number)?

 
The acronym VIN stands for vehicle identification number, a unique 17-digit alpha and numeric string of characters for each vehicle. VIN numbers have been mandated by the U.S Department of Transportation to be stamped on every vehicle since the early 1980s.
A VIN is used to track vehicle registrations, recalls, warranty claims, thefts and insurance coverage. Each character in the VIN has a specific purpose.

Decoding the VIN by character
1st character – identifies the country of manufacture. For example, U.S. (1 or 4), Canada (2), Mexico (3), Japan (J), Korea (K), England (S), Germany (W), Italy (Z)
2nd – identifies the manufacturer. For example, Audi (A), BMW (B), General Motors (G), Ford (F), Honda (H), Mercedes-Benz (D), Nissan (N), Toyota (T), Volkswagen (V)
3rd – identifies the vehicle type or manufacturing division
4th through 8th - identifies vehicle attributes, such as body style and engine type
9th – called the “check digit,” the ninth character uniquely identifies the vehicle, ensuring that no two cars within a 30-year period have the same VIN
10th – identifies the model year
11th – identifies the assembly plant
12th through 17th – identifies the sequence of the vehicle off the assembly line, with the last four characters always numeric
Where is the VIN stamped?
Auto manufacturers stamp the VIN in several different places on a vehicle. The most visible one is through the front windshield, located on the driver side interior dash by the windshield. Another location is on the driver’s side door jamb. A VIN may be stamped on the front or top of the engine block, the engine frame and many other hidden parts of the vehicle.
Consumers can also opt to have their VIN permanently etched into various parts of the car, a practice encouraged by insurance companies to help discourage theft and selling of car parts.

2015 Porsche Cayman GT4: The Cayman's Potential, Unlocked

Hear that? It’s the sound of the Porsche 911’s pedestal cracking. The plinth on which Porsche has ensconced the 911, safe from threats like the 914, 944, and, most recently, the mid-engine Cayman, has been heretofore unassailable. Browse the spec sheets of the 911 and the Cayman, and like models such as the S and GTS are carefully and conspicuously separated by their engine outputs, the 911 always coming out on top. With the new Cayman GT4, Porsche is for the first time allowing one of its lesser vehicles to encroach on the 911’s space. And what a glorious encroachment it has turned out to be.
We could talk about the wild aerodynamic bits and Porsche dropping barriers between its models, but we’ll get straight to the most important GT4 fact: 385 horsepower. With that output, the GT4 finally marries the outstanding Cayman chassis not only with a level of power it deserves, but a level of power it is capable of handling. Sure, the lab coats in Stuttgart have spent more than 50 years telling physics they “can’t even” and somehow gifting the 911’s far-from-ideal ass-engined layout something resembling docility, but a mid-engine sports car is inherently better balanced.
In the GT4, power comes from a variant of the 911 Carrera S’s 3.8-liter flat-six. The engine is the biggest available in the Cayman lineup, and it’s 45-hp stronger than the GTS model’s 3.4-liter six. The suspension, according to Porsche, “consists almost entirely of components of the 911 GT3,” and combined with a 1.2-inch-lower ride height and dynamic transmission mounts, should improve on the Cayman’s already impeccable chassis performance. Porsche certainly used the GT3 for inspiration when it came time to design the GT4’s wild aerodynamic kit, which includes a huge fixed rear wing and a deep chin spoiler; the front fascia’s trio of cooling inlets also mimics the GT3 look.
Carbon-ceramic brakes are optional, as are carbon-fiber seat shells and a version of Porsche’s Sport Chrono lap-timer package with a new performance-tracking smartphone app. Standard gear includes leather and faux-suede sport seats, a sport steering wheel, and—unlike the 911 GT3—a six-speed manual transmission. Oh yes, eat your hearts out, GT3 early adopters.
With nearly the same output as the 911 Carrera S but the same hard-core focus as the 911 GT3, the Cayman GT4 should easily outperform most of the 911 lineup. Porsche claims the newest Cayman can hit 183 mph and sprint from zero to 60 mph in just 4.2 seconds. That acceleration figure is, like all of Porsche’s performance estimates, almost comically conservative. Our 325-hp long-term 2014 Cayman S reaches 60 mph in 4.2 seconds, and while Porsche hasn’t outlined specifics regarding the GT4’s weight, it’ll likely weigh less than any other Cayman. Figure on a sub-four-second zero-to-60 run once we strap our test gear to the car, considering we achieved 4.2 with a manual-equipped Cayman S.
Even swiping its suspension components from the GT3, the GT4 won’t exceed that 911’s on-track heroics. We’re told the GT4 matches the GT3’s 7 minute, 40 second Nürburgring lap time—the 2011 GT3’s, that is. Hey, Porsche, did you think we wouldn’t notice that the GT4’s 3.8-liter six makes 400 horsepower in the Carrera S, or that fitting the GT3’s PDK dual-clutch automatic could make the GT4 even quicker? Yet despite Porsche’s continued efforts to stymie the Cayman’s ultimate potential, the GT4—which will hit U.S. dealerships in July—creates a total mess for the GT3. That’s because at $85,595, the GT4 is nearly $50,000 cheaper than the GT3, and it comes with the manual so many enthusiasts pined for when the GT3 launched without one. Which would you choose as your track toy?

Local Auto Makers To Exceed Nigeria’s Vehicle Market Share In 2015

Local automobile manufacturers and industry experts have given great forecast for Nigeria’s automobile industry in the New Year.
The local manufacturers described 2015 as the year to break even, amidst observable sharp increase in automobile industry investors’ confidence in the new National Automotive Policy, which seeks to revive Nigeria’s local automobile manufacturing industry.
With over 20 automobile assemblage plants that began operation this year, according to data provided by the National Automotive Council (NAC), the manufacturers said they are set to exceed the 50,000 units new vehicles market share known as the country’s average benchmark in the last few years.
With the federal government bent on creating a robust market for locally made vehicles, the Nigeria Customs Service is expected to execute full implementation of the tariff arm of the country’s National Automotive Policy, which places a whopping 70 per cent tariff on fully built cars and used vehicles, while leaving local automobile manufacturers with only 20 per cent tariff on completely knocked down units (CKDs).
Stallion Nissan Motors
Leading local auto maker and largest distributor of new vehicles in the country, Stallion Nissan Motors Nigeria Limited plans to build 6,000 vehicles at its Lagos assemblage plant by 2015.
The forecast is a huge leap from 600 units which the company built as at March, 2014 when it closed accounts for the year.
The Nissan Patrol, a high-end jeep favoured by government officials, Nissan Almera and South African-modelled MP 300 pick-up vans are the three Nissan brands being built in Nigeria currently by Stallion NMN.
Hyundai Nigeria, another subsidiary of Stallion Motors will build over 10,000 units of its low-end i-Grand, the latest Nigerian-made car that has weakened the used car market.
Stallion’s group managing director, Mr Parvir Singh said the federal government has taken care of certain aspects of the country’s new automotive policy with which it seeks to develop production of cars and buses in Nigeria.
Assuring of the quality of cars and other vehicles assembled in Nigeria, the Stallion boss said, “government is monitoring every aspect of the process and every progress made gets certification from government.
“Manufacturing passenger vehicles is highly complex, unlike commercial vehicles. Vehicle manufacturing is a good process of industrialisation and nobody can short-circuit the process. This process is what we are following.”
As a typical backward integration plan, the auto policy provides a leeway for local auto makers, who will pay only 20 per cent tariff on CKDs compared to 70 per cent tariff on the fully built units (FBUs). About 50,000 new cars are imported into Nigeria annually.
Singh said the figure is not a cumbersome mark for all the automakers currently producing new vehicles in the country.
“The figure is even little for some three manufacturers. What I think we need now is more investment in social infrastructure by government. There is dearth of local skills,” Singh said.
Stallion’s assembly plant in Ikotun, Lagos, will also this year begin manufacturing of series of indigenous brands to be named “Stallion” which would be a totally Nigerian brand.
“Government is investing a lot of money in terms of duty saving from the manufacturers.
Innoson, PAN, Dana, Kia, Renault
Other leading automobile manufacturers include Innoson Motor Company, Peugeot Automobiles Nigeria (PAN) Limited and Dana Motors, which will begin manufacturing of Kia and Renault brands at its Isolo Lagos plants this New Year.
In 2014, PAN signed a new deal with its original partner, Automobiles Peugeot, France. The company is providing technical support to PAN Nigeria to assemble vehicles and manufacture CKDs in 2015.
PAN’s managing director, Alh Ibrahim Boyi stressed that part of PAN’s come-back plan is to maintain robust support centres across the country this year, with Lagos being a major focus.
“We are going to spread our after-sales centres so that when people have to repair our cars, they will have a place very close to them.
“Our cars today are really very competitive in performance and price and energy efficiency. We want to bring the good memories back to Nigeria. All products from us are domesticated for Nigeria and we have maintained that heritage and have to regain our leadership in Lagos market,” he said.
The Peugeot 301, 4008, 3008 and the Peugeot 508, all of which come in automatic transmission are leading brands assemble at the company’s Kaduna plant. Boyi said PAN had completely revamped its distribution network with new technical skills provided to staffs of distributors.
With its planned N10 billion Ikorodu plant which began operation this year, the Kewalram Chanrai Group, has dropped a forecast of 15,000 units for 2015.
The executive director of Kewalram Chanrai Group, Mr Raju Sawlani his company had seen a veritable window in Nigeria’s new National Automotive Policy and had tied up with FOTON, a Chinese automaker to begin assembling the company’s cars, buses and other vehicles in Nigeria.
“The group is known for setting up local industries and believing in backward integration. With the re-introduction of the auto policy, it has become imperative to set up local automobile assembly,” Sawlani said.
“I have strong conviction that the auto policy would transform the nation’s industrial landscape, leading to an increase in skills development, and conserve valuable foreign exchange,” he stressed.
Also this year, the local automobile assemblage and manufacturing industry is expected to generate about 100,000 direct and indirect employments.
Spokesman for Stallion Motors, Mr Manny Philipson said over 400 people, with over 95 per cent Nigerians have already been engaged at the company’s plant.
PAN Limited and the Kewalram Chanrai Group, also said their plants in Kaduna and Ikorodu respectively would each create about 300 direct jobs. A human resource manager, Mr Nnamaechi Frank said for each hundred workers directly employed by the auto companies, over 10,000 people would gain some forms of employment while directly or indirectly serving the automobile manufacturers.
“On job creation, the implication can beat our imaginations. From distributorship to roadside repair service providers, hundreds of thousands can be engaged meaningfully,” Frank said.
“If government stays on the policy, millions of people can be employed indirectly, and this is what matters most. This may be the catalyst for job creation and unprecedented economic age for Nigeria.
“I see that if this government and the succeeding ones remain faithful to this policy, it will get to a level that the auto companies can actually manufacture completely knocked down (CKD) units and this is where the unbeatable success in employment generation lies,” he said.
Involvement of commercial banks
In a bid to facilitate the acquisition of these locally assembled vehicles, some commercial banks have designed typical products to ease their acquisition. Consequently, Stallion Motors, Audi and Hyundai have partnered such banks as Diamond Bank and Skye Bank to create products target at prospective car owners to ease acquisition of Hyundai and Nissan cars made or assembled in Nigeria.
