Dual Fuel Conversion System
The gas used for Dual Fueling is sourced from either piped gas or from local storage. It is injected into the combustion air stream via a Gas Train consisting of a gas filter, a gas pressure regulator and a solenoid valve. A throttle valve at the end controls the proportion of the gas injected. The gas train is designed to accept input gas at low pressure and deliver it to the engine at a slightly negative pressure. Dual Fuel System delivers fuel gas to the combustion cylinders via the Gas Train into a special Air-Gas Mixer. Dual-Fuel Systems are based on proven gas engine components and powerful actuation and governing units. They ensure a perfect gas-air mixture quality and high conversion ratios.
Operating dual-fuel engines with up to 2 MW output, the gas controlled and gas mixer based systems are suitable for stationary applications as well as heavy-duty vehicles. The mixer is installed on the engine air inlet before the Turbo charger. Combustion is commenced by Diesel as the ignition source and followed by ignition of the Gas.
The gas mixer is an indispensable component of the fuel system. which takes care for quality of the mixture. Mixers provide a very homogeneous air and gas mixture and an optimal Air to Fuel Ratio (AFR) over the entire speed and load range of the engine.
- Located between the Air Filter and the Turbocharger
GAS TRAIN: Condition and control the gas supply to the Air Gas Mixer
Receives fuel grade gas at a low constant pressure and supplies to the Air Gas Mixer at atmospheric / slightly negative pressure.
The Gas train components are:
- Gas Filter
- DMV Double Solenoid
- Zero Pressure Regulator
- Main Adjustment Screw
