There are three types of regeneration: Active, Recovery, or Forced. If you own diesel engine you must be aware of the distinctions between them and choose the correct one for your vehicle. Regeneration is vital to your engine’s performance, and it can help you save money on fuel. Find out more about each.  

Active regeneration

Active regeneration is a process in which the exhaust system of diesel engines is cleared of soot. The regeneration process can take place every day, depending on the engine’s work cycle and the amount of soot it has built up over time. It could take up to 30 minutes. The process of regeneration could be interrupted if the vehicle is in a standstill for a long period of time. Diesel engine spares regeneration

Active regeneration involves raising the exhaust gas temperature to encourage the oxidation of soot in the exhaust. The process makes use of energy from fuel combustion in the engine to increase the temperature of the exhaust gas. The heat is then transferred to the exhaust stream, where it burns the soot that is in the DPF. Diesel engines do not have active regeneration.

A yellow warning light will illuminate when the regeneration process is interrupted. This indicates HIGH EXHAUST TEMPERATURE. The regeneration process will stop once the engine temperature returns to normal. Operators must make sure there is enough fuel to allow the engine to properly regenerate. Also, he must follow the directions in the InfoCenter to ensure that regeneration can start immediately. When regeneration is activated, the vehicle should be in idle mode and the coolant temperature should be at least 140degF.

Passive regeneration is automated, whereas active regeneration is initiated by the user. Regeneration that happens automatically and requires that the engine be actively operating. Passive regeneration occurs when the exhaust temperature of the diesel engine reaches 350° Celsius. This is equivalent to 662° F. In certain instances it is possible that the exhaust temperature is not high enough to start regeneration, which can cause problems.

Recovery regen

The active regeneration technique is a method that occurs when the engine ECU alters certain parameters and then raises the temperature of the exhaust. The extra fuel then reacts with the catalyst and ignites the soot inside the DPF. This regeneration technique is known as parker regeneration. However, it should not be employed in hazardous situations such as in areas where there are low-hanging branches or burning combustibles.

The frequency of regeneration varies on a variety of variables including the type of engine that is used and its load requirements. If the vehicle is designed for lighter loads, it might not be required to run the regeneration cycle on a daily basis. This case, it may be necessary to purchase an engine load bank. This could increase the cost of the engine. The operator should also be involved in the process of regeneration. The process can take between 20 and 60 minutes and can consume up to a half gallon of fuel. A slight whistling sound could be heard during regeneration. This is normal.

As a substitute for parts trading regeneration of diesel engine spares in marine vehicles is becoming more popular. Engine parts are susceptible to damage due to the harsh marine environment. A failure of one or more of the engine parts can pose a threat to the vessel’s security. To perform the procedure you must hire a team of skilled marine engineers and mechanics.

Forced regen

Forced regeneration is a typical procedure in maintenance of trucks. While it’s necessary to correct an issue and bring the vehicle to a repair facility and back, it’s crucial that fleets understand how to make these processes as efficient as is possible. There are some things to consider when regenerating a diesel engine forcefully.

For first forced regenerations are time-consuming and take between 30-60 minutes. The engine is also rendered inoperable by the heat generated during forced regens. This unnecessary downtime, coupled with the cost of labor and the use of a service bay, could result in a loss of hours. It can also impact the delivery times of fleets.

If your engine stops running after the regeneration process is forced, it’s likely that the DPF is not working properly. If this is the case, cleaning or replacing the DPF might be necessary. In other instances it could be that the problem is in a different component of the aftertreatment system. For these cases forced regen may not be the most appropriate option.

Forced regeneration can solve many common issues, including problems with a DPF filter that is over full or isn’t functioning properly. A blocked DPF can result in the vehicle being unusable or in the mode of limp. If the DPF isn’t working correctly it can be cleaned and replaced to ensure that your diesel engine runs smoothly.
