There are two main types of natural gas trucks based on the pressure levels of the gas they use: high-pressure natural gas trucks and low-pressure natural gas trucks.
High-Pressure Natural Gas Trucks
These trucks run on compressed natural gas (CNG), which is NGV-grade gas compressed to a pressure of about 3,000 to 3,600 psi. Because the gas is compressed, it takes up less room in the gas tanks. CNG trucks have a better range compared to LNG trucks. As a result, they are the most common type of natural gas truck. They are also cheaper compared to LNG trucks.
Low-Pressure Natural Gas Trucks
These trucks run on liquefied natural gas (LNG), which is natural gas that has been cooled to a temperature of -260°F. At this temperature, the gas turns into a liquid and takes up less space. LNG is denser than CNG, so it can provide more energy. As a result, LNG trucks have a longer driving range and are more suitable for long-haul driving. Because LNG trucks are more efficient, they are mostly used for heavy-duty trucks that need to drive for long distances. Apart from their efficiency, the main difference between LNG and CNG is the state in which the gas exists. While LNG is a liquid, CNG is compressed to a gas.
Other than the type of gas they use, there are no significant differences in the design and operation of CNG and LNG trucks. Both types of trucks have similar engines that run on natural gas instead of diesel or petrol. They also have similar driving experiences to conventional diesel or petrol trucks. However, the range of CNG trucks is limited compared to LNG trucks.
Most manufacturers of natural gas trucks have similar specifications for their products. Here are some of them:
Engine
Natural gas trucks have compressed engines, just like conventional trucks. The only difference is that the natural gas trucks' engines are cleaner. The engines require low-maintenance schedules. Some companies may provide a dual-fuel engine that uses diesel and natural gas.
Power and Torque
The power output of the natural gas trucks is almost the same as that of the diesel trucks. The power and torque figures for both trucks are comparable. As such, natural gas trucks do not compromise on power.
Transmission
Natural gas trucks come with automatic or manual transmissions. The transmission specifications are the same as those of diesel-powered trucks.
Dimensions and Weights
Natural gas trucks have similar dimensions and weights to diesel trucks. This includes the size of the cargo area, truck length, and height. Natural gas trucks also have the same load capacity as diesel trucks.
Safety Features
Natural gas trucks are designed with compressed gas in mind. The trucks have added safety features to minimize the risks associated with natural gas. These features are in line with international safety standards. The trucks also have the standard safety features found in diesel trucks.
Maintaining a natural gas truck is crucial since it ensures the truck performs well. Here are the maintenance requirements for a natural gas truck:
Engine Oil
Natural gas trucks have engine oils just like conventional trucks. Maintain the engine oil at the recommended level. Also, change the engine oil according to the manufacturer's recommendations. Using the right engine oil will prolong the life of the truck's engine and improve performance.
Air Filter
The air filter of a natural gas truck prevents contaminants from getting into the engine. Check the air filter regularly and change it if it is dirty. A clean air filter will enhance the engine's efficiency.
Fuel System
Natural gas trucks use compressed gas as fuel. As such, they have a compressed gas fuel system. Inspect the fuel system regularly for leaks or damage. Also, ensure all the connections are tight. A well-maintained fuel system will ensure the truck runs smoothly.
Ignition System
The natural gas truck's ignition system contains spark plugs, ignition coils, and other components. Inspect the ignition system for any signs of wear and tear. Replace the spark plugs and ignition coils once they reach their lifespan.
Cooling System
Natural gas trucks are equipped with a cooling system to prevent the engine from overheating. Ensure the coolant levels in the cooling system are at the recommended levels. Also, flush the cooling system every few years to get rid of contaminants.
Tires
The natural gas truck's tires must be in good condition for the truck to drive safely. Inspect the tires regularly for damage or wear. Also, maintain the recommended tire pressure. Change the tires once they reach the manufacturer's tread depth limit.
There are several factors to consider when choosing a suitable natural gas truck for a specific business operation. They include:
Business Operation Type and Size
Consider the type and size of the operation when selecting a natural gas truck. Long-haul operations require trucks with optimal fuel efficiency and a higher driving range. On the other hand, regional and local delivery operations need trucks that are easier to handle and maneuver.
Payload Capacity
Natural gas trucks have different payload capacities. Therefore, it is important to select trucks that can handle the intended load without exceeding the maximum weight limits. Also, consider the truck's performance regarding acceleration and climbing ability when carrying a payload.
Fuel Efficiency and Driving Range
Natural gas trucks differ in fuel efficiency, which is measured in gasoline-gallon equivalents (GGN). Additionally, consider the truck's driving range on a full CNG or LNG tank. For long-haul operations, trucks with excellent fuel efficiency and extended driving range are ideal.
Maintenance Requirements
Natural gas trucks require specific maintenance practices. Therefore, consider the maintenance requirements and schedule while selecting a truck. Some trucks have longer maintenance intervals or require fewer maintenance tasks, which can reduce downtime and save costs.
Comfort and Safety Features
Natural gas trucks come with different comfort and safety features. Consider the level of comfort and safety features required for a specific operation. Some trucks have advanced safety features, such as collision avoidance systems and lane departure warnings. Additionally, features like ergonomic seating and climate control improve driver comfort.
Financing Options
Consider the available financing options when selecting a natural gas truck. The initial cost of the truck can be significant, so explore different financing alternatives, such as leasing or purchasing loans. Some manufacturers offer financing packages, making it easier to acquire a natural gas truck.
Most natural gas truck maintenance procedures are easy and can be done by following the right steps. Some of the procedures that can be DIY include:
Checking the CNG Gauge
Inspecting the CNG gauge on the driver's side instrument panel is essential to ensure its proper function. If the gauge shows full or empty, regardless of the actual tank level, it requires immediate professional attention. Driving with a faulty gauge poses safety risks and can lead to costly repairs if left unaddressed. It's crucial to have a functioning CNG gauge to monitor compressed natural gas levels accurately.
Inspecting the Pressure Relief Device (PRD)
Checking the PRD is essential for safe natural gas truck operation. The PRD, usually located on the tank's end opposite the fill valve, should be free of rust and corrosion. A compromised PRD may not function correctly in emergencies, endangering passengers. Additionally, the PRD cover should be securely fastened with a wire tie. An unsecured cover exposes the PRD to debris and damage, compromising its protective capabilities. If the cover is not tied down, use a wire tie to secure it promptly.
Inspecting the Gas System
Regular inspections of the gas system components within the first 5,000 miles of operation and every subsequent 10,000 miles are crucial for safe natural gas truck operation. Thoroughly examine the CNG fuel lines, fittings, and other parts for signs of wear or damage. Address any issues immediately to prevent gas leaks, which can pose serious safety risks. Additionally, keep the gas system components clean and free of debris. Contaminants can lead to system inefficiencies and potential hazards.
Filling the Fuel Tanks
Proper refueling techniques are essential for safe natural gas truck operation. Always follow the instructions provided by the fuel dispenser. Before starting the fueling process, ensure that both fuel tank doors are open to facilitate a safe and efficient fill. During refueling, never attempt to open the fuel tank doors while the nozzle is still attached to the connector. This practice can lead to dangerous situations and potential damage to the fueling equipment. Additionally, if any issues arise during the refueling process, promptly contact a trained service technician for assistance. Their expertise can address fueling concerns and ensure natural gas trucks' safe and reliable operation.
