Quicken your pace. Because the turbo lags behind the extra fuel, many trucks blast smoke when they suddenly go full speed. When towing a large weight in low gear, the effect is amplified. Try attaching your vehicle to a 5000-pound payload and driving it uphill at full power.
How do I get my diesel truck to roll coal?
“I’m curious how it is permitted for diesel pickup trucks to be tricked out to “roll coal,” given that you have to be Air Care certified before receiving license plates,” writes Pete from Boulder. If they can’t stop these kinds of pollutants, it seems like a waste to me. Trucks add to our ozone days, and it’s no fun to be stopped at a red light when the signal turns green and a black cloud surrounds everyone, especially those walking or riding a bike.”
In the past, I was also a victim of rolling coal. I won’t guess on the thoughts of truck owners who modify their vehicles in this manner, but those who spoke with me about it gave me various reasons why. “We just like the way it looks and like to see who can make the biggest plume,” for example. We believe that climate change is a hoax, and we enjoy annoying those who drive green vehicles. The engine produces more power for me. We don’t like it when cyclists take up the entire road. We’re protesting the abolition of oil jobs. We enjoy having complete control over our trucks and doing things that no one else can.”
Let’s take a closer look at rolling coal. It simply entails altering a newer diesel engine to pump more fuel into it than it can handle. This procedure produces a massive plume of thick, black exhaust that contains unburned fuel. Many older diesel truck engines built under previous air quality standards are capable of rolling coal without any changes. In 2017, the state of Colorado declared rolling coal unlawful, although only the act of rolling coal was made criminal, not the act of changing your car.
“In other words, you could be prosecuted if you released poisonous gases on someone, but not if you made your car capable of doing so,” said Danny Katz, executive director of CoPIRG. “I believe there was a proposal in the 2021 legislative session to upstream this legislation and make it illegal to alter or knowingly sell an altered car, but there were questions about who would be liable, and I don’t believe it was actually developed or introduced.”
A diesel vehicle can be converted to roll coal in a number of ways. Using a defeat device such as a “delete tuner” or “delete kit” is one of the most convenient methods. They readily connect to the truck’s OBD2 port, and the driver may modify several of the stock engine settings, including the fuel mixture that causes the black smoke, with the push of a button. If the driver needed the vehicle to pass Colorado’s AirCare emissions rules, the same device could quickly adjust the settings back to factory emissions.
“Yes, diesel owners could modify their vehicles several times if they wanted to waste time, energy, and money on a useless hobby,” says Dana TePoel, owner of Lake Arbor Auto in Westminster. “It appears absurd to us, yet it could happen,” says the author.
The US Environmental Protection Agency estimates that roughly 15% of diesel trucks in the US with original approved emissions have had their emissions systems tampered with, according to a report released late last year. Tampering with vehicle emissions controls or employing an aftermarket defeat device, according to the EPA Office of Enforcement and Compliance Assurance, is still unlawful. These defeat devices, according to the EPA, circumvent or otherwise render mandated emissions control systems inoperable, resulting in considerable increases in dangerous air emissions.
“About three times a week, a truck breaks down here,” TePoel added. “Older automobiles frequently fail due to high opacity,” says the expert (thick smoke). New ones frequently fail owing to missing or altered components, which are frequently missing or altered due to past owners.”
The EPA has recently targeted many big tuner manufacturers, including Premier Performance, which was fined $3 million earlier this year for marketing “defeat” devices. Companies who make tuners are no longer allowed to advertise publicly because to EPA restrictions, yet tuners that allow diesel users to roll coal still exist.
There are also more invasive methods for changing the engine. Another option to convert a diesel truck to roll coal, according to the website Truck of Mine, is to aggressively custom-tune it and install bigger injectors. During each injection cycle, injectors push a big amount of fuel into the engine, fooling your engine into thinking it needs more.
An officer may stop a vehicle with excessive emission, whether gas or diesel, issue a ticket, and compel the owner to make repairs, according to Colorado’s Department of Public Health and Environment. A violation of Colorado’s Nuisance Exhibition of Motor Vehicle Exhaust ordinance is punishable by a $100 fine. Operating a smoking car may result in further fines in several countries.
“We believe Colorado’s diesel emissions program has provided a major net benefit to the state’s clean air, and we certainly don’t want to see someone undo our clean-air progress with a campaign to dismantle the emissions program,” TePoel said. “It would be the same of banning all traffic signals because a few vehicles run red lights.”
In Colorado, the Smoking Vehicle Hotline program assists in identifying vehicles with excessive emissions and provides owners with information to urge them to make necessary repairs willingly.

What causes a diesel engine to smoke black?
We’ve all seen clouds of black smoke billowing from the exhaust stacks of heavy-duty diesel vehicles, especially when they’re hauling a hefty load or accelerating quickly. The black smoke is mostly made up of elemental carbon from incomplete combustion of diesel fuel, with traces of engine oil thrown in for good measure. Elemental carbon (soot), semi-volatile organic compounds, sulfates (mainly sulfuric acid), and water vapor are all found in the exhaust of a conventional diesel engine. When the diesel fuel charge in the combustion cylinder is incompletely combusted, black elemental carbon is generated for a variety of causes. When there is an excess of fuel (both diesel fuel and lubricating oil), inadequate residence time in the combustion zone, and/or insufficient oxidants, incomplete combustion occurs and soot forms.
Overfueling is the most common cause of black smoke from a heavy-duty diesel engine’s exhaust. Diesel fuel injector wear can cause overfueling by enlarging the nozzle opening or eroding the injector needle, allowing excess fuel to flow into the combustion chamber. Corrosion from polluted or high sulfur diesel fuel causes nozzle and needle wear in many circumstances. Because diesel engines are not intended to properly burn extra fuel, much of it is wasted and only partially combusted as it exits the engine. Particulate emissions (PM) can be increased by up to 85 percent as a result of nozzle and needle wear.
Black smoke is caused by dirty air filters that do not allow enough air (oxidant) into the combustion chamber to complete the burning of the fuel charge. Dirty air cleaners are thought to increase PM levels by 40 to 50 percent.
Black smoke is caused by excessive oil consumption caused by worn valves and valve stem seals, worn or stuck/sluggish rings caused by deposits, and worn cylinder liners. The incorrect oil for the job, long oil drain intervals, polluted oil, and failure to maintain proper oil levels in the engine can all cause engine wear and deposits. Wear and deposits can be reduced by performing regular maintenance with the prescribed engine lubricant. Excessive oil consumption can raise PM levels by up to 85%.
Premature engine wear and deposits, which lead to black smoke, can be avoided with regular maintenance and the use of the appropriate oil for the application. It’s possible that the fuel injector nozzles need to be cleaned or changed. It’s possible that air cleaners will need to be inspected, cleaned, or replaced. Excessive valve train, ring, and cylinder wear can be avoided with regular preventive maintenance such as frequent oil changes and top-ups and using the proper oil. Engine deposits that cause stuck and slow rings can be controlled by using high performance diesel engine oils. Excessive oil consumption caused by volatility can be reduced by using high-performance diesel engine oils with the right volatility.
Does rolling coal hurt your truck?
What is the impact of “rolling coal” on the environment? Rolling coal consumes fuel, reducing the efficiency of your engine. This is bad for the environment. Many people who choose to modify their engines in this fashion do so in order to take an anti-environmental position.
Is it illegal to roll coal?
California. Operating a vehicle “in a way that results in the escape of excessive smoke, flame, gas, oil, or fuel residue” is illegal in California. A vehicle can be cited for rolling coal under this law or others by the California Highway Patrol or local police.
Is it bad for a diesel to black smoke?
- Air filter is clogged. The presence of black smoke shows that the fuel has not been properly burned. In diesel cars, the internal combustion process necessitates a specific mixture of fuel and air. The fuel-to-air ratio must be correct; otherwise, the combination will be overly rich, resulting in black smoke.
- Injectors that aren’t working properly. Injectors are a crucial component of your fuel system. They should open and close at a specific moment, and if they don’t or become clogged, they’ll end up injecting a lot more fuel into the cylinder. When you accelerate your car, this incorrect process produces solid carbon residue, which emits black smoke from the diesel engine’s exhaust.
- EGR valve is clogged. By returning engine emissions to the combustion chamber rather than sending them directly to the exhaust emission system, the EGR helps to recirculate them. The carbon chucks have the potential to clog your EGR valve, resulting in power loss, fuel inefficiency, and the production of black smoke from your exhaust.
- MAF Sensor is a type of sensor that detects motion. It’s also crucial for the computer to calculate the correct amount of fuel to inject into the cylinder. The Mass AirFlow Sensor is in charge of forming the proper fuel and air mixture in the engine. If something is wrong with it, it will register greater airflow in the system and inject more gasoline into the engine. As a result, unburned fuel in your diesel engine will produce black smoke.
How do I stop my diesel from blowing black smoke?
Fouling injectors are a common cause of black exhaust smoke. Diesel Injector Cleaner (DIC), Diesel Fuel System Cleaner (DFSC), and Pro-Strength Diesel Fuel System Extreme Clean are all products that can assist remove injector deposits and decrease black exhaust smoke.
How do I stop my diesel from black smoke?
If you want to eliminate black smoke from your diesel engine, the first thing you should do is check the air filter and replace it if it’s unclean.
The presence of black smoke in the combustion chamber indicates that the fuel is only partially burnt. Water and CO2 are produced when a working diesel engine consumes the fuel. Black smoke indicates that something is stopping the fuel from completely burning, which is usually due to an unbalanced air-fuel ratio.
The air mixture entering the combustion chamber is the first place to look. The engine air filter, which may be clogged, is the most straightforward repair. The air-fuel ratio will run rich if there isn’t enough air getting to the engine, leaving unburned diesel fuel behind.
Can Turbo cause black smoke?
Blue smoke could be coming out of your exhaust pipe due to an oil leak in the combustion chamber caused by a damaged turbo housing. A burnt engine, clogged air filter, choked air intake duct to the turbo compressor, or flaw in your engine’s fuel injectors can all generate black smoke.
Can a bad fuel pump cause black smoke?
We get a lot of queries concerning gas and diesel engine difficulties because we have an ASE-certified master technician on staff. Some of them are rather broad and difficult to diagnose in a single chat. Not that we expect to be able to do so for everyone, but it’s good when we can cast some light on a situation that makes another person feel more confidence in their ability to go out and solve their difficulties.
“Black smoke” is one of those vague symptoms that suggests a problem but necessitates further inquiry to determine the source. Any smoke, in fact, would fall under this category. There’s not just black diesel smoke here; there’s also white diesel smoke and even blue diesel smoke. So, let’s go over some of the things to look for if you notice diesel smoke where it shouldn’t be.
The most prevalent type is black smoke, which is caused by an imbalance in the air-to-fuel ratio (too much fuel to not enough air). This indicates that either too much fuel is being added to the mix or not enough oxygen is being given to allow the fuel to burn. The black smoke contains particulates, which are huge diesel particles that would typically be burned as fuel. Any way you look at it, a diesel truck spewing black smoke isn’t going to achieve the best fuel mileage.
Faulty injectors, a faulty injector pump, a bad air filter (causing not enough oxygen to be delivered), a bad EGR valve (causing the valves to clog), or even a bad turbocharger are the most prevalent reasons of black smoke. Some of these issues are simple to resolve.
White smoke indicates that the fuel being fed into the combustion chamber is not being adequately burnt. White smoke can be caused by anything from low engine compression to water in the fuel to the fuel pump timing being thrown off because anything is preventing the gasoline from getting to the pump in the manner required for the pump to time and perform correctly.
Blue smoke is produced when motor oil is burned. Engine oil isn’t meant to seep into regions where it can be burned, therefore this is a mechanical issue. There could be a problem with the injector pump or the lift pump, allowing oil to combine with the fuel and be burned. It’s possible that the valves or valve stem seals are faulty. Oil seeps where it shouldn’t because of worn cylinders and piston rings (which X-tra Lube can help with). You could also have a minor problem like putting too much oil in the engine.
