How To Fill Up A Diesel Truck?

BOOM! Two blog posts in a row! Whoa! I had some free time because we were waiting at a receiver. This is a ‘educational’ topic that has been on my to-do list for a while, so here it is! Don’t get too worked up over it. Also, get some popcorn.

I like to refer to it as “feeding the beast.” Filling up a truck is similar to filling up a car, but there are a few key distinctions.

To begin with, the average car stores about 12-15 gallons of gas. Our truck is equipped with two 125-gallon tanks, allowing us to transport up to 250 gallons of diesel fuel.

The next significant distinction is that the average car runs on gasoline. Diesel is used in the large trucks. Most people are aware of this; the challenge is learning to refer to the foot pedal as a “accelerator” or “fuel pedal” rather than a “gas pedal.” Because if you call it a “gas pedal,” the boys will start reminding you to fill your blinker fluid (especially if you’re a girl). Blinker fluid, on the other hand, does not exist. I didn’t fall for that one, either. Despite the fact that I’m usually gullible… and blonde. 😉

Another distinction is a somewhat minor one: while filling a semi, it’s critical to ensure you’re pulling into the suitable “truck-friendly” fuel pumps. To begin with, they have diesel fuel. Second, each truck typically has two pumps (more on that later). Third, DEF is now available at most truck gasoline pumps, which I’ll discuss further below. Fourth, the canopy clearance is sufficient for a large rig. I’ve seen far too many photographs on the internet of trucks attempting to pull into a standard automobile gas station. Yes, they may have diesel, but you could end up stuck in the middle of nowhere, waiting for a wrecker to come to your rescue.

1. Look for a pump that is open.

2. Take a step back and line up.

3. Fill out the form with your details.

4. Tanks of diesel fuel, DEF, and a reefer.

5. Take a step forward and park.

6. Leave the fueling station and go inside for a receipt.

You may not have to wait if there is an open pump, but you may have to wait if all the pumps are full. Because space is limited and you don’t want to take up more place than required so that other trucks may get through and/or wait in line, you usually choose a truck to wait behind. When it comes to selecting a truck to wait behind, there is a little strategy to consider. You start by looking for a truck that doesn’t have a vehicle parked in front of it (standard practice after fueling is to pull up one truck length and park to open the pump for the next guy). This way, when the truck you’ve been waiting for arrives, he’ll be able to pull up and leave the pump open for you. You could have to wait a while if there’s a truck in front of him and the driver is inside having a poo or anything. Another thing to check for is how far along the motorist is in the fueling process – you can usually tell if they’ve just started or are almost finished. Get behind the person who’s almost finished. Last but not least, check to see if the vehicle has a reefer (refrigerated trailer). Because the reefer fuel tank is mounted on the trailer, drivers must pull up a short distance to let the pump to reach the tank. This tank doesn’t have to be filled every time the truck does, so the driver might not even fill their reefer tank, but it’s another item to keep an eye out for if you want to get in and out quickly.

Once your gasoline station is open, cautiously pull up and position your truck such that the pump hoses can reach the diesel tanks. It’s also crucial to keep an eye on the trailer as you move forward. When you go in a bit crooked, you want to make sure “ol’ Leroy,” the trailer (my trainer nicknamed the trailers “ol’ Leroy” and it stayed with me), doesn’t collide with another vehicle or the massive yellow cement poles between the fuel pumps.

When should I refill my diesel tank?

Once the tank is a quarter full, it is recommended that you refill it. Because the vehicle is lighter with a partially filled tank, you can get better gas mileage. Cleaner gas will also be available at the pump.

How long should you let a diesel idle before driving?

Early diesel-fueled trucks (from the 1930s) experienced a number of issues. The engine’s design made it difficult to start. The oils were thick and heavy, and the fuel had a tendency to congeal, making it difficult to start the engines, particularly in cold weather. The quality of the fuel was not as excellent, and it was not controlled as it is now.

Fuel engines and technology have vastly advanced over the years, yet for some reason, the old habit of leaving the engine running has persisted.

Myth: Before driving a diesel engine, it must warm up for 5 to 10 minutes at idle or longer, especially on chilly days.

Fact: This is one of the most popular diesel engine misconceptions. Newer diesel engines should be idled for no more than 3 minutes before driving, according to most engine manufacturers.

Allowing an engine to idle causes more damage to it than starting and stopping it. When compared to traveling at motorway speeds, idleing an engine generates twice the wear on internal parts. Idling increases maintenance costs and reduces the engine’s lifespan.

Fuel is one of our industry’s most expensive operating expenses. Idling has a negative influence on us because it increases our fuel and maintenance costs. In a truck, one gallon of fuel is consumed each hour of idling time. The bigger the engine, the more gas it uses. The price of a gallon of diesel is currently over $3.20 and is likely to rise this year. The expense of idling soon adds up with the number of pickup trucks, big trucks, and equipment we operate.

Why are diesel engines so big?

Diesel engines can be found in a variety of large vehicles, including trucks, buses, tractors, and so on. Obviously, these automobiles’ insurance is also taken into consideration.

  • High torque: Because heavy vehicles are used to transport a large load, such as cargo and passengers, they require a lot of torque at low speeds. Because diesel engines provide more torque than gasoline engines, they are recommended for big vehicles.
  • The fuel efficiency of a diesel engine is higher than that of a petrol engine because diesel burns at a slower pace than petrol at moderate temperatures due to its chemical composition. Also, because most diesel engine vehicles are utilized for business purposes, they demand a significant profit margin. Diesel engines are also less expensive than gasoline engines.

As a result, the cost of driving is substantially lower in the case of diesel engines than in the case of gasoline engines, saving the cost of transportation in commercial vehicles.

  • The compression ratio (CR) is the ratio of the volume of the cylinder and its headspace (including the pre-combustion chamber, if present) at the bottom of the piston’s stroke to the volume of the headspace at the top of the piston’s travel (‘top dead centre’, tdc).

When compared to gasoline engines, diesel engines have a higher compression ratio.

As a result, diesel engines can create the necessary torque for heavy-duty vehicles at low speeds.

Furthermore, when compared to petrol engines, diesel engines are larger and heavier. As a result, a diesel engine requires more room to fit. As a result, big vehicles employ diesel engines, whereas light vehicles use gasoline engines.

What temp does diesel fuel gel up?

This phrase is self-explanatory, as fuel gelling occurs when the petrol in your tank thickens to the point where it resembles gel. This only happens when the outdoor temperature dips below 32 degrees Fahrenheit, though it’s most likely to happen when the temperature is around 15 degrees or below. This is due to the presence of paraffin wax in diesel fuel. When you need to improve the lubrication and viscosity of the gasoline, that’s a terrific ingredient to have…but it’s not so great when the wax thickens as it gets colder.

As a result, the thicker fuel clogs the filters and eventually stops flowing completely, preventing you from starting your vehicle. So, how can you tell if your car is experiencing fuel gelling? If it’s below freezing outside and your diesel-fueled vehicle won’t start, it’s most likely due to fuel gelling. Fortunately, this common diesel fuel winter issue can be avoided. To be more specific, there are two basic strategies to avoid this problem.

How do they make diesel exhaust fluid?

As a result, in an SCR-equipped car, the exhaust gas from the engine passes through a particle filter first, catching all of the soot and ash produced by burning a relatively dirty fuel. That eliminates the “rolling coal” feature of old diesel engines, which made them unpopular in the United States in the 1960s, 1970s, and 1980s.

The exhaust gas passes via a nozzle that sprays diesel exhaust fluid into the stream of gases after it passes through the particulate filter. DEF is created from deionized water and urea in its purest form. Yes, urea is found in urine — please stop laughing — but this is a refined form of the molecule that is primarily employed in agriculture as a fertilizer component.

The heated exhaust gas and DEF are then sent into the catalytic converter, where the urea in the DEF and the exhaust gas react with a range of metallic compounds to convert nitrogen dioxide and monoxide to nitrogen and water. Nitrogen is the most abundant element in the air we breathe and is completely safe for the environment. Water is just that: water.

This is certainly a simplified description of how SCR works, but other from the extra step of injecting urea into the exhaust stream, it’s very similar to how your gasoline-powered car’s catalytic converter works. To minimize emissions, most modern diesel engines employ SCR in conjunction with exhaust gas recirculation and a diesel particulate filter (DPF).

Exhaust gas recirculation, or EGR, is a typical procedure that reduces the quantity of unburned fuel in a vehicle’s exhaust fumes. It is utilized in nearly all current ICE engines. EGR has the disadvantage of reducing vehicle performance and fuel economy, as well as adding another complex system to an already complex machine.

As a result of EGR’s flaws, several firms are removing it from their engines and replacing it with somewhat more DEF to treat the exhaust gases, achieving similar results without sacrificing performance or efficiency.

Isn’t all of this appealing? SCR and DEF, on the other hand, are not universally seen as beneficial. I mean, you have to keep it filled all the time, right? Isn’t it also expensive? Nope. Every time you replace your oil, an usual tankful of DEF will need to be refilled. It’s also largely water, so it won’t break the bank. A 2.5-gallon pack of BlueDEF (as opposed to the stuff your dealer may sell) will put you back about $80.

What is a diesel satellite pump?

Two diesel fuel tanks are standard on an over-the-road truck. These tanks, known as saddle tanks, are located on both sides of the truck cab. Because of the size of the truck, when a driver fills these tanks with a single hose, the process takes a long time.

Satellite fuelling is a system in which fueling stations have satellite systems with tandem dispensers on each side of the vehicle, allowing a driver to fill both saddle tanks at the same time.

The product flow rate in a typical satellite fueling facility is relatively high (35 to 40 gallons per minute), and a single meter measures and records the flow of product being dispensed into the two truck fuel tanks at the same time.
