Natural Gas Engines for Heavy-Duty Applications

Natural Gas Engines for Heavy-Duty Applications - Heavy Duty Vehicle Design Parker Hannifin Motion and Control Technology BlogAs fuel costs continue to rise and vehicle emissions standards grow increasingly stringent, many are turning to natural gas as an alternative to gasoline or diesel. Natural gas provides comparable amounts of power and acceleration while producing lower levels of emissions and particulates, all at a significantly lower cost.


Benefits of CNG

The benefits of utilizing compressed natural gas (CNG) powered vehicles and fueling systems in heavy-duty applications include:

  • Up to a 25 percent reduction in carbon dioxide output, 75 percent reduction in carbon monoxide and 100 percent reduction in particulate emissions.
  • Access to cheap, domestically produced fuel where supply is greater than demand and should remain so for the foreseeable future.
  • Increased safety due to a low risk of flammability.
  • A comprehensive delivery structure consisting of existing underground natural gas lines.


Making CNG work

Parker CNG powered vehicle filter - Heavy Duty Vehicle Design Parker Hannifin Motion and Control Technology BlogLeaving the challenge of creating a fueling infrastructure and sourcing CNG-powered vehicles aside, the actual design of a CNG-powered system requires different approaches. Natural gas must be filtered at each step throughout the extraction and delivery process. At the wellhead and beyond, filters remove excess moisture, particulates, and chemicals used to treat, or "sweeten" the gas stream. A range of various filters, such as those from Parker Racor, cleans the gas before it is compressed and removes any contaminants that it picks up in the pipeline. They also clean it one last time as it goes into a dispenser for use in a vehicle to ensure that it is as clean as possible and will not damage the vehicle's fuel system. 


Sealing solutions for CNG

compressed natural gas (CNG) seals - Heavy Duty Vehicle Design Parker Hannifin Motion and Control Technology BlogIn addition to filtration, Parker also offers sealing solutions for CNG vehicles and fueling systems. Given that CNG is lighter than air, leaks are both harder to identify and more difficult to contain. At the same time, CNG-fueled vehicles are exposed to extreme ambient temperatures, from arctic cold to desert heat. As such, a CNG fuel system requires special seals and hoses. CNG-capable compounds exhibit wide operating temperature ranges, high degrees of elasticity and high tensile strength ratings.

From the filler neck to the conveyance system

I like how you mentioned that alternatives to gasoline and diesel are being sought out due to rising costs and stricter vehicle emissions. The owner of the farm I work on is thinking of looking for a CNG tractor repair specialist because he noticed the other day that our natural gas machinery was making strange noises after turning it on. It seems like a good idea for the farm owner to think about taking our tractor to a reputable professional to help us fix our equipment so we can get back to tending to the land.
