The internal combustion gasoline engine — we have a love/hate relationship with it. It creates a lot of pollution. It is incredibly inefficient. It spews carbon into the atmosphere. It makes us ...

Carbon build-up reduces fuel economy by restricting airflow into the engine, disrupting the fuel spray pattern from injectors ...

Most modern vehicles have multi-port fuel injection (MFI) with a separate fuel injector for each cylinder. This system mixes the fuel and air together right in the intake port for eachengine cylinder ...

Delphi is developing an engine fuel injection technology that could improve the fuel economy of gas-powered cars by 50 percent, potentially rivalling the performance of hybrid vehicles at less cost.

Automotive engineers are very good at incremental improvements to existing technologies, and that skill will be much tested in meeting increasingly stiff fuel-economy rules between now and 2025. For ...

As we entered into 2014, the industry was abuzz with the acronym “GDI,” otherwise known as Gasoline Direct Injection. The “gasoline” distinction is significant because direct injection has existed in ...

Over time and miles, your car might start to slow down. It might not accelerate as quickly as it once did; the engine may not run as smoothly as you remember, or the fuel economy may dip—but ...

The earliest and simplest type of fuel injection, single-point simply replaces the carburetor with one or two fuel-injector nozzles in the throttle body, which is the throat of the engine’s air intake ...

For years, Toyota Motor Corp. has put hybrids at the center of its powertrain-technology strategy, all but oblivious to the rapid fuel-economy advancements rivals have made in the humble gasoline ...
