Fuel System Diagnostics Is All In The Fuel Trim Numbers
With lean-burn operating strategies being built into many of today’s gasoline direct-injection and gasoline compression ignition engines, it’s important to build a foundational knowledge of how fuel trims work in the real world.
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 it on a vehicle with direct fuel injection. You can, however, witness the symptoms of a bad injector.
Carter Fuel Systems Announces 11 New Part Numbers, Plans To Showcase Product Line At AAPEX
These new part numbers target late-model applications and extend Carter’s coverage to reach more than 1.3 million additional passenger vehicles.
Direct Injection Engine Problems
Gasoline Direct Injection engines go by many names including GDI, DI, FSI and more. Car manufacturers have introduced this engine technology in response to federal emissions and fuel mileage requirements. While these engines offer a lot of upsides as far as fuel economy, horsepower, lower displacement and fewer tailpipe emissions, they also have some downsides.
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.
Getting The Big Squeeze: How Mazda’s New Spark-Controlled Compression Ignition Engine Runs Long On Fuel, Short On Emissions
Until Mazda recently introduced its new Spark-Controlled Compression Ignition (SpCCI) gasoline engine, internal combustion engines (ICEs) were classified as either spark or compression ignition. The historical differences between the two were obvious: spark-ignition engines were quiet and smooth and compression-ignition engines were not.
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.
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 says this new part number introduction significantly extends the company’s coverage of passenger vehicles on the road today, with applications that fit popular models such as the Nissan Altima, Volkswagen Jetta, Kia Optima, Chevrolet Equinox and Subaru Outback.
Flex Fuel: Ethanol vs. Gasoline
For political and economic reasons, the use of ethanol gasoline in the U.S. has always been controversial. To better explain, the U.S. and Brazil are the world’s leading producers of ethanol-blended gasolines. In Brazil, ethanol is an economic issue because the country’s hot equatorial climate is very hospitable to the rapid growth of biomass, which is cheap organic waste that can be made to produce ethanol.
