Q: Numerous articles were published (including yours) in the past suggesting that direct injection gas engines might experience drivability problems at higher mileage due to deposits building up on ...

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 ...

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 ...

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 ...

Fuel injectors don't just deliver fuel. They meter it, shaping the spray so the air-fuel mixture burns in the way the engine wants it to. When deposits build up, injector fuel flow can decrease and ...

Gasoline direct injection (GDI) continues to be a weapon in the technology armoury of automakers in their fight to reduce CO2. Manufacturers believe that homogeneous applications of GDI will be ...

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 ...

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 ...
