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 Engine Conversion Technology is matured and used around the world, with over 5,000 engine conversions to date. The system converts diesel engines into clean burning natural gas engines at a fraction of the cost of a new engine.

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 overhaul and is in the process transformed from a diesel engine to a natural gas engine (CNG or LNG).

Thousands of diesel engines are overhauled every year. Using Omnitek’s conversion technology, these engines can be “overhauled” into natural gas engines -- the difference in cost is minimal. During their long service life of up to 20 years, diesel engines are routinely overhauled – the infrastructure, capacity and knowledge base exists. Diesel-to-natural gas engine conversions make economic sense and is the only viable option to increase the natural gas vehicle population in a reasonable amount of time.

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 and no emissions regulations:
Omnitek Kit, Engine Modifications, and Labor to convert about $ 7,000 - $ 10,000.
Gas tanks, engine overhaul parts and installation are extra.

For engines with turbo charger and no emissions regulations:
Omnitek Kit, Engine Modifications, and Labor to convert about $ 8,000 - $ 12,000.
Gas tanks, engine overhaul parts and installation are extra.

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

The cost to convert a power generator depends a lot on the size of the engine. Converting a 1000kw generator can cost up to $ 120,000. A 300kw generator can be converted for about $25,000. Payback time is generally less than 6 month, since the fuel savings is relatively high.
