Different vehicles operate on different types of fuel. Nonetheless, the use of diesel-fueled cars has been seen to be embraced by many compared to gasoline. According to the California Energy Commission, diesel has turned out to be the fuel of choice because it can be used by heavy-duty vehicles since it has an extended engine life. Moreover, compared to gasoline, diesel contains more energy per gallon of up to 12%. However, despite all this, more and more people are now transitioning to using compressed natural gas (CNG) with their engines. It has proven to have running costs compared to any other type of fuel. This is why we will talk about CNG engine maintenance for those who are using it or are planning to use it in the future.
When you think about engine maintenance, it usually brings to mind oil changes and tire rotations. However, compressed natural gas (CNG) engines come with their unique challenges requiring regular attention. The good news is that by following a few simple guidelines, you can ensure your CNG vehicle runs like the day you bought it for many years to come.
Have Your Cylinder Pressure Tested At Least Once Per Year
All cylinders should be carefully inspected annually regardless of use. However, they are essential if your car is used as a daily commuter because the elapsed time between inspections will be much shorter. That’s why CNG engine vehicles are built with two-way communication systems between the engine control unit (ECU) and the cylinder pressure sensors. This way, if there is a problem with the CNG cylinder, it will be detected immediately, and appropriate action can be taken before any major issues arise.
Cylinder Rust Removal
It may seem odd that rust could cause natural gas tank problems, but it’s not out of the question. As water accumulates inside gas tanks from condensation or exposure to humid environments, corrosion may form on metal components, including the cylinder walls and valve stems. This accumulation of rust can lead to a host of issues, including compromised welds, cylinder leaks, and even tank ruptures.
Look Out For Damage
When it comes to damage caused by accidents or environmental exposure, it is a good idea to have a professional inspect your CNG vehicle. For example, suppose you were in a collision, and the frame of your car sustained structural damage during the wreck. In that case, there is potential for this compromised section of your vehicle to puncture one or more cylinders upon impact, which would understandably put your safety at risk as well as require the replacement of multiple components.
Watch Out For Leaks
Unfortunately, not all gas leaks are easily seen with the naked eye. Leaks have a way of sneaking up on you, especially those which go unnoticed for long periods. When your CNG vehicle is being refueled or filled from a pressurized nitrogen canister, you will likely hear an audible hissing noise from the pressure vent on the side of your car. This vent helps relieve excess pressure from the tank to maintain safe levels for transport and is not considered a leak. But any time you notice this noise while your car is parked or idling, there could be a severe problem with one of your CNG cylinders which require immediate attention.
Follow these simple steps for optimal CNG engine care throughout your vehicle’s life cycle. Have a professional inspect your gas tank annually to ensure that it is in good working order. In addition, look out for odd sounds while refueling your car (which may indicate potential problems), and avoid parking over unstable surfaces, which could lead to leaks caused by ground shifts or erosion.
