Along with the dream of increasing fuel economy and reducing gas emissions, the gasoline direct injection system has risen as the significant core technology around the world as motor-driven mobility increases. With our technical knowledge and experience of gasoline direction injection systems since our founding in 1987, Hyundai KEFICO began mass producing gasoline direct injection systems in 2010 and has independently developed gasoline direct injection systems since 2015.

We have secured control technology for 150bar, 200bar, 250bar, and 350bar GDI engines, and we have secured development capacity through prior research on 600bar engine control systems. Hyundai KEFICO’s 600bar engine control system helps to improve engine performance with optimized fuel injection control and responsiveness that is 13% faster than that of the current 350bar system.

Hyundai KEFICO's gasoline direct injection system provides optimal engine performance, fuel economy, and reduced emissions at the same time through downsizing and turbocharging. Also, we provide system solutions as a response to the latest emissions certifications such as China7, Euro7, and SULEV30.
