There are three types of regeneration which are Active, Recovery or Forced. If you have diesel engine you must be aware of the distinctions between them and choose the correct one for your vehicle. Regeneration is vital to the engine’s performance and can help you save money on fuel. Learn more about each one.
Active regeneration is a method in which the exhaust system of a diesel engine is cleaned of soot. The regeneration process may occur once or several times a day, based on the engine’s duty cycle as well as the amount of soot it has built up over time. It can take as long as 30 minutes. The process of regeneration could be delayed if the vehicle is stopped for a prolonged duration. Diesel engine spares regeneration
Active regeneration is the process of raising the temperature of exhaust gas to encourage soot oxidation. The process makes use of energy from fuel combustion in the engine to raise the temperature of exhaust gas. This heat is then transferred to the exhaust stream, where it burns the soot that has been accumulated in the DPF. Diesel engines do not have active regeneration.
If the regeneration process is interrupted, a yellow warning lamp will light up. This is an indication of a high exhaust rate. When the temperature of the engine returns back to normal, the regeneration process will stop. The operator must ensure that the engine has enough fuel to properly regenerate. The operator must also adhere to the guidelines in the InfoCenter so that regeneration will begin immediately. When regeneration is activated the vehicle must be in idle mode and the coolant temperature must be at least 140degF.
Passive regeneration is automatic, while active regeneration is initiated by the user. Passive regeneration occurs naturally and requires that the engine is running. Passive regeneration occurs when exhaust temperature for diesel engines reaches 350° Celsius. This is equivalent to 662° F. Sometimes, the exhaust temperature is not high enough to trigger regeneration. This can lead to issues.
Active regeneration is a procedure that occurs when the engine ECU alters certain parameters and increases temperatures of exhaust. The additional fuel then reacts with the catalyst and ignites the soot inside the DPF. This is also known as parker regeneration. However, it shouldn’t be used in dangerous situations such as in areas where there are low-hanging branches or the presence of combustibles.
The frequency of regeneration is dependent on a variety of aspects, including the type of engine used and the load requirements. It may not be necessary for the vehicle to run the regeneration process every day if it is designed for light loads. In this scenario, it might be necessary to build an engine load bank. This could double the engine’s cost. Another crucial aspect is the involvement of the operator in the regeneration process. The process can take between 20 to 60 minutes, and it can consume as much as half a gallon fuel. In the process of regeneration, a whistling sound may occur however, this is completely normal.
As an alternative to parts trading the regeneration of spare parts for marine diesel engines is becoming more well-known. The marine environment can be extremely harsh on engine components and a malfunction of one or more of them could compromise the security of the vessel. Therefore, a skilled team of marine engineers and mechanics should be hired to perform the task.
Forced regeneration is a standard practice in the maintenance of trucks. While it’s necessary to correct an issue and take a vehicle to a service center and back, it’s crucial that fleets understand how to make these processes as efficient as possible. There are a few things to consider when force-regenerating a diesel engine.
For starters, forced regens are time-consuming, often lasting between 30 and 60 minutes. The process also generates substantial quantities of heat, which renders the engine unusable until it cools. This unnecessary downtime, coupled with the expense of labor and the use of a service bay could result in lost hours. Furthermore, it can affect fleets’ on-time delivery rates.
If you’ve noticed that your engine stopped working after making it necessary to regenerate it is likely that there’s a problem with the DPF. If this happens, it could be required to clean or replace the DPF. In other cases, a problem might lie in a different area of the aftertreatment system. In these instances forced regen may not be the best option.
Regeneration can be a solution to many common problems, such as an DPF filter that has become too full or is not functioning properly. A blocked DPF can lead to an unusable vehicle or a an inability to drive. Fortunately that if the DPF isn’t working correctly it is possible that the DPF can be cleaned and replaced to keep your diesel engine running smoothly.
