Injectors

WMI offers a line of injectors purposely designed to work with dimethyl ether (DME) – a clean-burning, renewable fuel and an alternative to diesel. There are three models in the lineup:
Mechanical Injector for Dual Fuel Diesel-DME
440cc/cyl Generator
M-05-WG
  • Designed for WG-M-DDME-05 dual fuel generator

  • Work with both diesel and dimethyl ether (DME) fuel

Electronic Injector for Dual Fuel Diesel-DME
440cc/cyl Generator
E-05-WG
  • Replaces the mechanical unit injector

  • Capable of increased fuel pressure from 400bar to 1000bar

  • Responsible for a 23% engine efficiency increase at peak load generation.

Electronic Injector for DME Fueled Engine
1,600cc/cyl
E-30-WX
  • Hydraulic Electronic Unit Injector (HEUI) designed to operate with the low lubricity DME fuel.

  • Fuel intensification allows injection pressures of 2000 bar, highest in the DME space.

  • Proven to exceed the baseline Diesel performance while reducing the combustion emissions
