Diesel particulate filter and AdBlue technology – an environmental benefit, a bane for forestry machinery operators
The diesel particulate filter (DPF) is an important component of newer forestry machinery. Its main tasks include reducing the amount of exhaust particles emitted into the atmosphere, which helps protect both people and the environment. Meanwhile, the AdBlue technology used reduces nitrogen oxide emissions.
The most common defect associated with particulate filters is a blocked filter element due to excessive soot accumulation. When this occurs, the result can be reduced engine performance and increased fuel consumption.
To fix this problem, the filter must be replaced or cleaned according to the manufacturer’s instructions. In some cases, it may be necessary to install a new filter if it cannot be cleaned properly.
Another common malfunction is an incorrect pressure difference between the exhaust system and the atmosphere when the engine is running at full load. This can cause further soot deposition on the filter element, as well as reduced engine performance due to excessive back pressure in the exhaust system. To solve this problem, check that all connections in the exhaust system are properly sealed. If necessary, have your vehicle inspected by a specialist for potential problems that may be causing this problem.
Moving on to AdBlue technology, the most common problem is injector malfunction due to improper operation or lack of maintenance. This results in too much or too little fluid being injected into the exhaust system, which can lead to reduced engine performance, as well as increased fuel consumption due to incomplete combustion of the diesel and AdBlue mixture in the cylinders. The best way to solve this problem is to replace or clean any damaged injectors according to the manufacturer’s instructions.
In conclusion, particulate filters and AdBlue technology have great environmental benefits, but they can also cause many problems. This is because they represent an additional component that requires care, maintenance and repair.
So how to take care of the DPF in forestry machinery to minimize the risk of failure ?
- use an oil that after combustion does not leave a large amount of soot, for example, with markings such as LowSAPS, DPF, Emmision System Protection or ACEA Class C
- fill up with good quality fuel
- use fuel additives that help burn off soot
- change the air filter regularly
- avoid short-time operation
- check the EGR valve and clean it regularly
Investing in prevention saves time, money and effort in the future.
