You will see a lot of stories around the web this week indicating that Volvo’s "Mean Green" truck has established a new world speed record. Volvo neglected to mention in the press release that it was the world hybrid truck speed record it had attained and hundreds of sites regurgitated the release verbatim without thought. The world land speed record is 1227 km/h - the Volvo ran about 1000 km/h slower than that.

BMW Daimler electric car project

Mercedes-Benz parent company Daimler and BMW are typically seen facing off against each other to win the hearts, minds and wallets of luxury car buyers. However, the challenges of developing a mass-produced electric car have inspired the two pillars of German luxury to put aside their rivalry and team up on a city car project.

Automatic transmission problem

Vehicles encounter automatic transmission problems usually on the basis of one or two particular factors. These are abuse and low fluid levels. Of course, one factor is capable of influencing the other, in that low fluid levels may be caused by abuse or may in turn reduce the amount of abuse that an automatic transmission can endure without failing.

Diesel Fuel Injection

One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor. A port injection system injects fuel just prior to the intake stroke (outside the cylinder). A carburetor mixes air and fuel long before the air enters the cylinder. In a car engine, therefore, all of the fuel is loaded into the cylinder during the intake stroke and then compressed. The compression of the fuel/air mixture limits the compression ratio of the engine -- if it compresses the air too much, the fuel/air mixture spontaneously ignites and causes knocking. Because it causes excessive heat, knocking can damage the engine.

Diesel engines use direct fuel injection -- the diesel fuel is injected directly into the cylinder.

The injector on a diesel engine is its most complex component and has been the subject of a great deal of experimentation -- in any particular engine, it may be located in a variety of places.

How fuel injection sistem work

Introduction

In trying to keep up with emissions and fuel efficiency laws, the fuel system used in modern cars has changed a lot over the years. The 1990 Subaru Justy was the last car sold in the United States to have acarburetor; the following model year, the Justy had fuel injection. But fuel injection has been around since the 1950s, and electronic fuel injection was used widely on European cars starting around 1980. Now, all cars sold in the United States have fuel injection systems.

Volkswagen crowdsources its way to a Hover Car

The world of personal mobility transporters doesn't bring a whole lot of glamor. The Segway was never exactly an enviable ride, and newer concepts like the GM EN-Varen't any better. But a Volkswagen that hovers a few feet over the ground? That channels a mix of Back to the Future and The Jetsons that adds some excitement to the personal mobility segment.
