Major performance enhancements can be achieved by adding a turbo charger or super charger to an engine. In this blog, we explain the technology while looking at the advantages and disadvantages of each.
In order to understand turbo chargers and super chargers, one must first realize that an engine operates on the ability to pass air through itself while igniting fuel. This process normally involves drawing air into the engine due to an expanding cylinder size as a piston moves downwards. The exception is the Mazda rotary engine which expands the chamber by a rotating process of an offset cam lobe type of geometry. This discussion will focus on piston based turbo/superchargers. In either case, the expanding size causes a suction that draws in air. Fuel is mixed into the air via a carburetor or by fuel injection. Turbo chargers and super chargers are devices that pump additional air into the chamber by forcing the air into the engine in addition to the vacuum that sucks in air. By forcing air, better engine efficiency is achieved.

Despite plummeting oil and petrol prices many of the best selling cars across global markets are compact saloons and hatchbacks. The strong sales in what many would predict to be a down market for small cars may well stem from the lower price tag associated with a compact or it may have to do with the improved quality, styling, and safety across the class. Whatever the reason may be, sales are pushing record levels. Let's have a look at the top compacts of 2015.

Take a look around, and you'll probably see a lot of Toyota vehicles on the road. This really should be no surprise, since Toyota makes some of the most-reliable vehicles. This means they stay on the road longer. Not everyone likes buying a new car every three years, or making expensive repairs every few months. In New Zealand, Toyota, including the Lexus luxury line, has been the best-selling brand for 26 years running. For 2013, Toyota / Lexus captured 21.4% of sales, just under the combined sales of Ford and Holden.
In fact, three of the top six best-selling cars in New Zealand are Toyotas, including the Toyota Corolla, in its sixth year at number one, the Toyota HiLux, now 32 years as the best-selling commercial vehicle, and the Toyota RAV4, in sixth place. Ford Ranger came in third, but just barely, Suzuki Swift came in fourth, and Holden Commodore came in fifth in total vehicle sales for New Zealand in 2013.

Growth in the infrastructure, in the road networks in Africa means a larger market for cars. Could this be why most of the foreign donor aid received from is directed to developing the infrastructure? Africa needs many cars, trucks, vans and buses to keep mobile. Transport, as we know, is the life and blood of the economies of the world.
The twilight years of the 20th century saw the economy of Africa grow enormously. Today, there are more resources in the continent and with the era of the dictators coming to a close end; she is investing her time in the exploitation of the resources. Recent discoveries of billions of barrels of oil in Northern Kenya, Uganda and elsewhere attest to this. However, even with all reasons for Africa to smile, she isn’t out of the woods yet, but she will be, eventually.

Used vans are big in the passenger transport business in Africa. Only a small portion of the 1 billion plus people in the continent own private cars. The rest depend on the public transport system to travel from one point to another, mostly for work. Although much of the transport system is underdeveloped, people still have to move.

Gottlieb Daimler had the foresight to build the first truck in 1896 to meet the growing needs of commerce in Germany. It wasn't until the Galion Allsteel Body Company modified a Model T in 1913 that the pickup truck as we know it today began to evolve. In the early years, a pickup body had to be special ordered, so they were only used for work purposes, but by the 1990's 85 percent of the most popular trucks were being sold for personal use, never seeing a work site. The 2015 best trucks are more apt to have all of the creature comforts associated with a passenger vehicle than they are to carry a heavy payload on a daily basis. Despite the comforts offered, the most popular trucks still offer the towing and cargo capacity needed to tackle any job. Let's have a look at 2015's best trucks.

While consumer 3D printing is a recent innovation, the idea goes back at least thirty years; and it’s quite possible that their introduction into mainstream society will revolutionize a variety of fields, including the automotive industry.

There may be a ton of things that Africa is known for; but one of the best kept secrets has got to be the African motorcar rallies. Thanks to the rugged terrains on most African roads; especially those located off the beaten path, these stand at being among the most challenging rallies all over the world.
Depending on where you live in the world, seasonal changes throughout the years can range from mild to wild. In the Northern Hemisphere, temperatures can range as low as -20 °F (-29 °C), in the winter, to as high as 100 °F (38 °C), in the summer, in the same region! North American Vermont is said to have two seasons, mud and snow, thanks to copious amounts of precipitation and heavy forest cover. On the other hand, Kenya, like most African countries, essentially has only two seasons, dry and wet.
No matter what season, however, each presents special challenges for driver and vehicle, alike. Different seasons can tax your engine, electrical system, tires, brakes, and driver, not to mention paint and glass, in different ways. Here are some tips to prepare your vehicle for whatever conditions you may face, no matter what season.

Have you ever looked at the description for a vehicle in a commercial, classified ad, or the sales brochure, and asked yourself, “What are all the abbreviations, initialisms, and acronyms?” Every automaker uses automotive-speak and, like all abbreviations, it makes it easier to describe things in shorter terms. For example, isn't it easier to say “ABS” in conversation than “Anti-Lock Braking System?” In an automobile, to save space on the dashboard, an “ABS” light may illuminate to let you know the system is activating or is malfunctioning. “ABS” is much quicker to recognize than, and takes up much less space than, the entire “Anti-Lock Braking System” spelled out on the dashboard. Here are a few common automotive-related abbreviations, initialisms, and acronyms and what they mean.
