Fuel Injector Diagnostics: Thinking Through The Problem
There is almost no way to inspect the spray pattern of the fuel injector while it is on the vehicle, and it is impossible to inspect on a vehicle with direct fuel injection. You can, however, witness the symptoms of a bad injector.
SKYACTIV Technology: Ultra High-Compression, Direct Injection Engines Are Making Fuel-Economy Waves
The secret to Mazda’s fuel economy gains with its SKYACTIV-G engines is in its approach to combustion management. Diesel engines are typically about 30 percent more efficient than gasoline engines partly because of their significantly higher compression ratios (16:1 or higher for diesels versus 9:1 or 10:1 for most gasoline engines). Raising the compression ratio of a gasoline engine also improves its thermal efficiency, power output and fuel economy.
OTC Introduces 4 New Tools To The Fuel Injector And Pump Product Line
The new tools help technicians complete fuel system jobs faster and are compatible with a wide variety of vehicles, says the company.
Volkswagen, Audi Direct Fuel Injection System
For the past decade, almost every vehicle that Volkswagen and Audi has sold in the U.S. has been equipped with direct fuel injection. These FSI, TSI and GDI systems allow for better fuel economy and power. The switch to direct injection has also allowed Volkswagen to downsize its engines from 2.0L to 1.4L on base models without losing any power, while still improving fuel efficiency.
Giving It The Gas: When The Fuel Pump Isn’t The Problem
The most famous last words in automotive diagnostics are, “We’ve always done it this way.” In many cases, “always done it this way” consists of diagnosing a fuel pump by squirting some type of liquid or gaseous hydrocarbon into the air intake. Case in point, a 2011 Nissan Rogue had suddenly stalled on a busy summertime highway.
Rethinking Fuel Pump Diagnostics And Sensors
The technician diagnosed the 2011 Rogue as a bad fuel pump by squirting propane into the air intake. With propane, the engine runs, without propane, it stalls. But, after the fuel pump was replaced, the Rogue exhibited the same problem, which was a very slow, unsteady idle followed by an engine stall.
Carter Fuel Systems Releases All New Parts Catalog
Available in both print and online versions, the new catalog was developed for automotive service professionals as a resource to quickly look up product options for all their applications by vehicle year, make and model.
Carter Fuel Systems Introduces 19 New Part Numbers

Direct Injection Diagnostics: Taking Pressure Readings
Direct injection is becoming standard on more and more late-model vehicles. These systems can be a diagnostic challenge, but with the right foundation, problems can be solved profitably.
Carter Fuel Systems Introduces 22 New Part Numbers
Carter Fuel Systems, a U.S.-based manufacturer of complete fuel system solutions, has announced the introduction of 22 new part numbers, including 18 fuel module assemblies, three gasoline direct injection (GDI) mechanical fuel pumps and one fuel tank sender assembly. “Carter will maintain our focus on the technician as we introduce new part numbers throughout 2017,”
