Audi/VW Direct-Injection Issues And Carbon Deposits
Through the years, injection systems have incorporated more sensors like air temperature, EGR temperature or exhaust gas temperature, and the emissions systems monitor how efficiently everything is working. But the systems didn’t change a whole lot until about 2006.
Using Scan Tools To Diagnose Faulty Fuel Pumps
The most common diagnostic procedures for fuel pumps in the past were analog and hands on. Most fuel pump-related problems could be solved with a pressure gauge and voltmeter. Today, the scan tool is the most important tool when diagnosing a fuel supply problem.
Bosch Expands Training Offerings; Adds Course In Advance Gasoline Direct Injection
Bosch has announced that it is expanding its repertoire of training courses to include an advanced course on Gasoline Direct Injection Technology (GDI) for automotive technicians. This one-day class will be offered in various locations throughout the United States and will launch in 2013.

Tech Talk – Engine Innovations to Reach Government Fuel Standards
In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.
Diagnostic Solutions: Testing Fuel Delivery Systems – Checking the Basics First Can Facilitate Diagnostic Strategy
Vehicle fuel delivery technology has evolved to include conventional, pulse-modulated and direct fuel injection systems, with each having a specific set of components and testing issues. Gary Goms explains how to avoid some of the most common mistakes in diagnosing fuel delivery systems.
Fuel Injection System: How Does it Know?
With the days of carburetors behind us, the electronic fuel injection system in the cars we drive today is king. While carburetors mixed the air and fuel together and the mixture was sucked into the cylinder and burned, modern electronically controlled fuel injection injects the right amount of fuel, at the right time for optimum fuel efficiency and economy, and driving performance. But the question remains, how does it know what that ‘right amount’ is and when’s the ‘right time’ to inject?

For its first 40 years, Chevrolet seemed content designing, building and installing four- and six-cylinder engines in its
Tech Feature: Delivering the Fuel – Not a Fuel Pump Return
Although electronic fuel injection has become the norm since the late 1980s, some technicians still don’t understand the value of having a good diagnostic procedure for testing electric fuel pump functions. While this is not something a repair shop owner wants to hear, proper fuel component testing has become a growing industry issue, as unnecessary parts warranty returns continue to be a problem for manufacturers.
New Emissions Technology: Fuel Economy, Global Warming & Alternative Fuels
We can expect to see more innovations designed to improve fuel economy and/or eliminate our dependence on oil altogether, says Technical
