DEN-SO X1 Series

The DENSO X1 series fuel injectors are purely mechanical hydraulic injection systems specifically developed for early-generation construction equipment such as excavators and tractors. Their core value lies in structural simplicity, low maintenance cost, and high adaptability to harsh environments.

Designed for reliable power delivery without electronic control units, these injectors rely solely on fuel pressure to actuate the needle valve. Enhanced vibration resistance and dust protection are achieved through a triple-sealing configuration: metal bellows, fluororubber rings, and a labyrinthine fuel passage. This design effectively blocks dust intrusion, making the X1 series an economical and dependable solution for basic fuel delivery in high-dust, high-vibration working conditions.
