Diesel-to-Natural Gas Conversion System and Parts

Omnitek is the only provider of a real world solution for Diesel Fleets. The Omnitek Diesel-to-Natural Gas Conversion Technology is matured and used around the world. The system converts diesel engines into clean burning Natural Gas engines at a fraction of the cost of a new engine.

Omnitek is currently providing this solution to customers in 12 Counties and has been used to converted over 4000 diesel engines around the world.

Omnitek's proprietary technology overcomes past problems of unreliability and poor performance found in first-generation gas engine technology. Omnitek's technology outperforms competitors in side-by-side comparisons in all relevant areas, including cost, efficiency, performance, emissions and reliability.

Conversion Kits
Diesel engines come in many sizes and can be divided into two groups:
1. Engines without a turbocharger - can use a simple reducer/mixer system (CIMS).
2. Engines with a turbocharger - must use electronic fuel injection (ECM).

All diesel engines can be converted to natural gas. The power level of the engine after conversion depends on numerous issues, such as natural gas quality, power level of the original diesel engine, emission levels required etc. A properly converted engine can make as much power using natural gas as on diesel. Diesel engines converted to natural gas generally require added components as well as some mechanical changes to the engine. Basically the diesel engine undergoes a complete rebuilt and is in the process transformed from a diesel engine to a gas engine.

Conversion Steps
1- Disassemble engine.
2- Checking components and replace as necessary.
3- Modify pistons for gas use (lower compression ratio).
5- Modify cylinder head for spark plugs.
6- Install camshaft sensor and timing wheel.
7- Reassemble engine.
8- Install throttle body, ignition system, gas mixer or fuel injectors.
9- Tuning of the engine (fuel and ignition).

For engines without turbocharger Conversions cost: Omnitek Kit, Engine Modifications, and Labor to convert about $ 7,000 - $ 10,000. Gas tanks and installation are extra.

For engines with turbo charger Conversion cost: Omnitek Kit, Engine Modifications, and Labor to convert about $ 9,000 - $ 14,000. Gas tanks and installation are extra.

Time to convert: A Team of 5 - 7 technicians can convert 5 - 7 vehicles in one week.
