NATURAL GAS ENGINE PRODUCTS

Searching online for natural gas engine products? E3 has released a new line of ignition products for natural-gas burning engines that includes spark plugs, ignition coils, and oxygen sensors. With the Environmental Protection Agency's (EPA) tightening of regulations governing tailpipe emissions, there has been a push to meet increasingly lower (near zero) thresholds of air pollutants. Depending on the type of vehicle, its drive cycle and engine calibration, converting to natural gas can lower lifecycle greenhouse gas emissions when compared to conventional fuels.

Natural gas is a low-carbon, cleaner-burning fuel that can provide a significant reduction in harmful pollutants, especially when considering lifecycle emissions or replacing older conventional vehicles. For environmental efficiency, E3 natural gas spark plugs have a multiple prong design that delivers a higher spark voltage for your natural gas engine. Whether your engine runs on compressed natural gas (CNG) or liquefied natural gas (LNG), either alternative fuel can result in a significant reduction of hydrocarbon, carbon monoxide, oxides of nitrogen, and greenhouse gas emissions.

When comparing the two alternative fuels, both perform favorably against current vehicle emission standards. Overall, the lifecycle emissions of CNG and LNG are nearly identical. Converting conventional engines to run on natural gas is a good option for commercial applications, such as fleet operations. Because the EPA requires conversion system manufacturers to demonstrate that the an engine meets or exceeds the same standards as the vehicle's original engine, always install E3 natural gas ignition products and have your conversions done by a reputable retrofitter.

E3 Spark Plugs began as a research and development company that invented a superior spark plug for automotive, light truck, lawn & garden and power sport applications. The same commitment to R&D has been applied to the natural gas line of spark plugs, coils, and oxygen sensors to provide the highest standards of quality. Our natural gas engine products always deliver better ignition capacity and are designed to withstand high combustion temperatures and pressure.
