Do You Need A Catalytic Converter On A Diesel?

Yes! A catalytic converter is present in diesel cars, although it is not the same as in gasoline or gasoline-powered vehicles. Exhaust Gas Recirculation (EGR), Diesel Particulate Filtration (DPF), Diesel Oxidization Catalyst (DOC), and Selective Catalytic Reduction (SCR) are the four phases of pollution control used in today’s diesel engines (SCR). The DOC and SCR are the two steps referred to as catalytic converters, as their names suggest. This is due to their usage of catalysts to aid chemical reductions in the reduction of vehicle emissions.

The two-way catalytic converter is compatible with most diesel automobiles and engines. The single component of the two-way oxidation cat is the DOC, which converts carbon monoxide to CO2 and hydrocarbons to water and carbon dioxide.

Modern cars use three-way catalytic converters, which are more inventive. To oxidize carbon monoxide, they have a two-way converter (DOC). They are, however, equipped with an SCR reduction catalyst to minimize nitric oxide and nitrogen dioxide emissions, collectively known as NOx.

Does a diesel engine have a catalytic converter?

A Diesel Oxidation Catalyst will be installed in every diesel system. It is responsible for converting carbon monoxide to carbon dioxide as well as breaking down any unspent fuel. This part of the diesel catalyst system works in the same way that it does in a gas cat. It is almost always the first part of the exhaust system to be installed.

Want To Know How To Ship?

Catalytic converters for diesel engines are made of metal. Because of the paucity of precious metals such as platinum, palladium, and rhodium, diesel engine cats are sometimes undervalued. Some diesel cats, on the other hand, are worth a fair amount of money. For an accurate price, you can email images of your diesel cats to our team.

Do modern diesel cars have catalytic converters?

The latest generation of diesel engines consists of a three-part system that includes a highly efficient engine, ultra-low sulphur diesel fuel, and an improved emissions control system.

The advanced electronic engine management system is the ‘brain’ of a modern engine, collecting and processing signals and data from on-board sensors and then coordinating the DPF and SCR exhaust aftertreatment systems, among other things.

The ultra-low sulphur content of the fuel (less than 10 parts per million) provides for better emission management. As a result, the engine can use the particulate filter to collect soot particles, lowering emissions and improving air quality.

Furthermore, diesel engines’ excellent efficiency is aided by common rail high pressure diesel injection systems. These systems improve the ignition and combustion processes by increasing the pressure in the injectors and providing greater fuel atomisation. This guarantees that the common rail receives only the amount of gasoline required by the injectors. It also allows the filter to be’regenerated’ on a regular basis by burning off the accumulated soot.

Catalytic converters, adsorbers, and particle filters are used in the latest generation of diesel engines to convert up to 99 percent of combustion engine exhaust pollutants (HC, CO, NOx and particulates). Carbon monoxide (CO) and unburned hydrocarbons (HC) are oxidized into CO2 and H2O, while NOx, i.e. NO and NO2, is reduced into inert N2, effectively eliminating harmful gases and lowering air pollution.

By creating and combining technology that can directly address air pollution challenges, the sector has proved its commitment to improving air quality.

The ‘precautionary principle’ was used at a time when there was still a dearth of epidemiological information about particle health impacts, mandating the eradication of carbon particles through the use of DPFs on all new diesel automobiles sold in Europe from 2011 forward. The Review of Evidence on Health Aspects of Air Pollution (REVIHAAP) published by the World Health Organization (WHO) in 2013 corroborated this, stating that ultrafine particles have hazardous effects on the human body.

The function of the wall-flow DPF is to trap and store particulates over the whole particle size range. Soot particles are deposited as a soot layer as exhaust gas travels through a porous ceramic wall honeycomb structure. This’soot cake’ screens out ultrafine particles as well as storing soot.

As a result, under real-world driving conditions, particle mass and number emissions from diesel vehicles are effectively managed, with the number of particles reduced by several orders of magnitude. High exhaust temperatures burn the soot accumulated in the DPF on a regular basis, renewing the filter and preparing it for the next round of soot collection.

High-performing, efficient diesel engines

Because of advancements in diesel engine performance, NOx and particulate matter (PM) emission limitations have been dramatically reduced over the last 15 years.

DPFs, in practice, remove over 99.9% of particles, including ultrafine particles. Although real-world NOx emissions did not necessarily improve at the same rate as the Euro 3 to 5 requirements, the AECC’s vehicle measurements database revealed an overall decreased trend.

For more than a decade, AECC has been tracking vehicle emissions that occur outside of authorized procedures. It began with the Artemis test cycle, which is a lab-based test that is more indicative of real-world driving than the previous regulation NEDC test cycle.

Since 2012, on-road tests have been conducted using vehicles equipped with a Portable Emissions Measurement System (PEMS). The graph below depicts the actual NOx reduction achieved by the diesel vehicles that AECC has tested throughout the years.

Is it OK to drive without a catalytic converter?

Many customers question, “Can I drive without my catalytic converter?” when faced with the costs of recovering a stolen “cat.”

Yes and no are the answers. A automobile can technically run without a catalytic converter. However, this is not a long-term viable strategy. Here are some of the issues you’ll encounter if you don’t have a catalytic converter.

Loud Vehicle Noises and Missing Catalytic Converter

Extremely loud vehicle noises are the first indicator of a stolen catalytic converter. When driving without a catalytic converter, your vehicle will sound like it is roaring, especially when starting or giving it gas.

Rough Driving and Acceleration

Your vehicle will drive more erratically when your exhaust is uncontrolled. Normally, your engine pushes exhaust through the catalytic converter. This powerful exhaust push will result in unpleasant, uneven acceleration if this component is not installed.

Annual Vehicle Inspection Failure

You will fail both your NC safety inspection and your NC emissions inspection if you do not have a catalytic converter. While the failure of the emissions inspection may be evident, you may be asking why a missing catalytic converter would result in a safety inspection failure.

An exhaust system check is part of your annual safety inspection, and it looks for missing or manipulated components. This includes, among other things, your catalytic converter, muffler, exhaust pipe, PCP valve, and EGR valve.

As a result, without a catalytic converter, you will be unable to renew your car registration. About our list of everything checked during your yearly safety inspection, you can find more information on exhaust system tests.

Harmful Car Emissions

Because it converts pollutants into less dangerous byproducts like water vapor and carbon dioxide, your catalytic converter is called that. Your vehicle will no longer filter and reduce dangerous emissions such as hydrocarbons, nitrogen oxides, and carbon monoxide if this component is missing. This is not only detrimental for the ecosystem, but it can also result in dangerously low air quality. These harmful contaminants can enter your home, for example, when you park in your garage.

Avoiding a $250 Fine

Theft does not happen to everyone who drives without a catalytic converter. To increase their horsepower, some people remove their catalytic converters. If police discover that you purposefully removed your catalytic converter, you could face a $250 punishment.

This does not apply to catalytic converters that have been stolen. “For ordering or allowing a person to tamper with an emission control device of the vehicle so that the device becomes inoperative or fails to perform correctly,” the fine reads. However, if your catalytic converter was stolen and you use workarounds to delay replacing it, your actions may mirror those of a driver attempting to tamper with their emissions system. This is why it’s critical to report a stolen catalytic converter as soon as possible.

Do diesel cars have catalytic converters stolen?

When the price of precious metals rises, so does the desire for parts that contain them, raising the danger of catalytic converter theft. Since 1992, catalytic converters (CATs) have been installed in the exhaust systems of the majority of petrol cars, and since 2001, diesel cars.

Do Thieves steal diesel catalytic converters?

Thefts of catalytic converters have increased by nearly 400 percent since 2020! Catalytic converters have been stolen from automobiles, trucks, and buses at an alarming rate recently. The precious metals used to make these pollution control devices are extremely valuable.

How much is a stolen catalytic converter worth?

With the ongoing COVID-19 pandemic, a global semiconductor chip scarcity, falling car sales, and rising new and used car prices, the automotive industry and consumers are facing difficult times. Add to that the current uptick in catalytic converter thefts around the country, and you’ve got a recipe for disaster. Consider yourself fortunate if you’ve never heard of catalytic converters.

Catalytic converters are essential components of a vehicle’s exhaust system. They’re made to prevent dangerous carbon monoxide and unburned hydrocarbon emissions from fossil-fuel automobiles. They can also be sold for a lot of money on the scrap metal market. The cost of reselling a catalytic converter varies by vehicle model, however it can cost anywhere from $100 to $500. According to the Montreal police department, a catalytic converter for a van or vehicle is worth $500 to $1,500.

Why are they being stolen in the first place? Because the catalytic converters contain valuable metals such as palladium, rhodium, platinum, and gold. In many cases, the value of some precious metals has nearly doubled in the last three years, increasing demand and providing an incentive for thieves to take converters and sell them for a quick profit to naïve or unscrupulous metal recyclers.

It’s a nightmare for the victim because car replacement parts and repairs can cost thousands of dollars, not to mention the bother of making insurance claims and being without transportation for weeks or months.

I can assure you that I speak from personal experience. In November of 2018, the catalytic converter from my 2001 Honda Accord was taken from a car detailer’s shop near Toronto Pearson International Airport in Mississauga. Thieves are drawn to Hondas, Toyotas, cube vans, and trucks with high roofs. In less than two minutes, they can remove converters. The more valuable metals inside the catalytic converters, the older the car.

Unfortunately, I wasn’t the only one in Peel, a 1.5-million-strong metropolis west of Toronto that comprises Brampton, Mississauga, and Caledon. Catalytic converter thefts were reported in 18 cases in 2018. There were 106 cases in 2020. This year, as of Sept. 28, 2021, there have already been 211 instances, a surge of 11-fold in the Peel region alone.

This alarming increase of catalytic converter thefts isn’t limited to Ontario. In 2018, there were 323 instances in Montreal. By 2020, the number had risen to 2,219, a 587-percent increase from the previous year. Similar alarming statistics have been reported by Calgary police, with 205 cases reported in 2019. Between August 2020 and August 2021, the number of cases increased by about 525 percent, to 1,280.

Similarly, there were 28 thefts in Vancouver in 2018. By 2020, that number would have risen to 204. That number could have been larger if there had been no pandemic restrictions in place at the time. According to Sergeant Steve Addison of the Vancouver Police Department, “2020 was an aberration for thefts due to COVID-19 regulations, as there were fewer automobiles parked outside and fewer out-of-town tourists.” With the pandemic limitations lifted and more individuals returning to work, he anticipates the number of thefts to climb.

Tom Finch, 61, of Lowbanks, Ont., a small village on Lake Erie, was surprised to learn that both of his company vehicles – Chevrolet Express 3500 vans modified into non-emergency patient transportation ambulances – had been destroyed this summer. Both vehicles were parked outside, near a police station, in a protected location with surveillance cameras.

“They’re lightning fast.” Finch recalls, “We didn’t even see them go underneath.” Finch didn’t bother to file a claim with his insurance company. He maintains that two separate insurance claims were required because the occurrence could not be covered under one policy. “Going through insurance wasn’t worth it — we ended up paying out of pocket,” Finch adds. The total cost was $4,500 — for just one vehicle. He retired the other van because it had greater damage and was more expensive to fix. Because no replacement components for the vehicle he was repairing were available in Canada, Finch had to wait two weeks for the catalytic converter to be shipped from Los Angeles, resulting in lost time and further headaches.

No one was apprehended in Finch’s case, which is unsurprising. Because catalytic converters do not have serial numbers, this type of theft is difficult to prove. Thieves must be caught in the act or formally recognized by witnesses, using evidence such as photos or videos. Many police departments are currently collaborating with automakers to have serial numbers placed on catalytic converters in the future; according to the Montreal police, some manufacturers may begin doing so as early as next year. That’s a wise move that may dissuade some crooks.

For the time being, police advise having your vehicle’s serial number engraved on your catalytic converter by a professional. Also, park in a well-lit, secure place or in your garage whenever possible. Earn it difficult for criminals to make a quick buck at your expense by making it easier for them.
