What is a four-stroke gasoline engine?

Four-stroke gasoline engines are the most prevalent internal combustion engines on the market today. Found in automobiles, light-duty trucks, motorcycles, and other equipment types, they work by converting chemical energy from gasoline into mechanical energy.

PFI vs GDI Engines

Faced with demands for greater fuel economy, consumer engine manufacturers innovate continuously to balance efficiency with performance. Unsurprisingly, there's an intense focus on fuel injection systems to address these needs. And all that focus has led to one of the most prevalent engine hardware trends: the growing use of gasoline direct injection (GDI) technology over traditional port fuel injected (PFI) designs.

Industrial Gearbox Gear Types

Industrial gearbox gears transfer power between a system and allow for a wide variety of speeds/loads to be achieved for a fixed range of input speed/loads. They come in many unique designs and materials depending on the application.
