The problem of air pollution around the globe is real and serious. In most countries, the transportation sector uses mostly diesel-powered engines, which are heavy polluters. To correctly convert a diesel engine to a low-polluting CNG or LPG engine is costly, technologically challenging and timely. Most of the countries also import the diesel fuel they use. Not only is the fuel expensive, but it also causes excessive air pollution. However, some countries have large reserves of natural gas but no technology to use it in engines.  The conversion of diesel engines to natural gas would decrease the country’s dependence on foreign fuel and help them utilize the abundant natural gas resources.

Omnitek approaches the issue of converting or replacing of high-polluting diesel engines to clean burning natural gas engines by offering two main options, which in large part are dictated by the level of technological capabilities within the country and financial feasibility.

Omnitek may work with local companies in an effort to convert high polluting diesel engines to clean burning natural gas, or will supply new dedicated CNG engines. (At the customer's request, Omnitek may rebuild/convert the old engine at the Omnitek facility)

      -- Under Solution #1 Omnitek will supply engineering support, for a small per-vehicle royalty, to rebuild the engines locally to Omnitek specifications on a "Technology Transfer" basis. This offers an economic benefit and boost to the local economy. Then the engines are being equipped with the Omnitek CNG fuel system, allowing for the engines to be tuned up to the EURO 3 standard.

Converting engines from diesel to CNG requires some good amount of expertise and may involve significant downtime.

Suggested engine modifications to assure engine reliability, optimized power, fuel consumption and emissions may include optimizing compression ratio, valve lift, valve timing, exhaust system and intake manifold. Special attention goes to engine cooling, engine lubrication and the potential issue of excessive oil consumption. A properly modified engine can make the same power as the base engine.

Gasoline Engine Conversions
            May need to improve cooling system efficiency
            May need engine oil cooler
            May need new valve seats
            For higher efficiency, engine compression can be increased 

Diesel Engine Conversions
            May need to improve cooling system efficiency
            May need engine oil cooler
            May need new valve seats, guides and seals
            May need new pistons and rings
            Engine compression must be lowered
            May need a new camshaft
            Ignition system must be installed
            Cylinder head modifications are needed to install spark plugs
            Custom cam or crankshaft position sensors must be made

      --- Under Solution #2 Omnitek supplies complete low-polluting alternative fuel engines in 4 and 6 cylinder configurations. This may be the better option when the existing engines are based on old and outdated technology, and when long downtimes are not acceptable. The dedicated alternative fuel engines can meet EURO II, EURO III and EURO IV standards.

 NOTE:

*         A detailed project evaluation and thorough inspection of the engines is required prior to purchase order acceptance.

*         Not all diesel engines can be successfully converted. Some engines require a great amount of mechanical changes to operate reliably. Some converted engines can not be tuned to the strictest emission standards.
