Our stationary diesel kit is a safe, simple, reliable, and inexpensive solution to run your diesel on a blend of between 50% and 75% natural gas, depending on load and engine characteristics.
The engine is started on diesel fuel and brought up to operating temperature. Then the supply of natural gas to the engine is turned on. Our kit draws natural gas straight from the pipeline and feeds it into your engine through a nozzle installed in the air intake system. The amount of engine vacuum determines the amount of gas introduced into the engine in the airstream. The piston then compresses the air/natural gas mixture in the cylinder. However, compression heat alone is not sufficient to achieve combustion. A reduced amount of diesel fuel is injected at the top of the compression stroke, and combustion of the air/natural gas/diesel mixture is achieved. The engine governor will automatically meter the diesel fuel at a dramatically reduced volume. An electric solenoid controls the gas flow, so that when the engine shuts down, the supply of gas is stopped.
Because stationary diesels run at a relatively constant load, our kit works well on both naturally aspirated and turbocharged engines. The only modifications made to the engine are a small hole drilled into the air intake pipe, another small hole drilled into the air filter box, and two wires patched into the electrical system to control the gas flow solenoid. You can choose to run your engine on either straight diesel, or a natural gas/diesel blend, to take full advantage of any fluctuations in fuel prices.
Because less diesel fuel is burned, less soot ends up in both the atmosphere and the engine crankcase. Oil change intervals can be increased dramatically.
