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 ...

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.

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 ...

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 ...

What it does: The high-pressure system injects fuel directly into each cylinder of the engine to increase power and torque without sacrificing performance or increasing emissions. An advanced engine ...

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 ...
