The illustration shows the inflow (A) of contaminated oil, the filtration of the oil (B) and how the cleaned oil (C) flows to the engine.
Seal
The seal ensures that the oil filter closes tightly and prevents oil loss.
Double beading
It increases the stability and strength of the filter housing and ensures that the connection between the different parts of the filter is robust and withstands pressure differences.
Non-return valve
It prevents the oil filter from draining after the engine shutdown.
Connection thread
The connection thread allows the oil filter to be attached to the engine. It ensures a secure connection and enables easy replacement of the filter.
Support jacket
The support jacket provides additional stability and protection for the filter media.
Filter media
A microporous, specially impregnated filter media enables a high particle separation rate.
Bypass valve
It ensures a continuous oil supply to the engine at low ambient temperatures and viscous oil by temporarily bypassing the filter.
Pressure-resistant filter housing
The pressure-resistant filter housing withstands the high pressures that can occur in the oil circuit. It protects the filter media and the internal components from damage.

Hose connection
The hose connection enables the diesel filter to be connected to the vehicle's fuel system.
Water drain
The water drain serves to drain water that may accumulate in the diesel due to condensation or contamination. This is important as water can impair the performance of the engine and cause damage.
Filter cover
The filter cover protects the filter media and the internal components of the filter.
This technique is used to increase the stability and strength of the filter housing.
Multilayer filter media
The multi-layer filter media improves filtration performance by providing a larger surface to remove contaminants and particles from the diesel.
Water sensor
The water sensor detects when water accumulates in the diesel. It can send warning signals to the vehicle control unit that the water drain should be activated.
Water drain tube
The water drain tube directs the drained water from the diesel filter to the outside.
Electrical connector for water sensor
The electrical connection for the water sensor enables the sensor to be connected to the vehicle control unit. This allows the sensor to transmit information about the water level in the filter and issue warnings, if necessary.

High-quality materials and meticulous workmanship are crucial. In addition, precise coordination of the filtration properties is essential, as they influence each other and must be optimally matched for excellent filtration performance.
Commercial vehicle operation is uncompromisingly geared towards the requirements of reliability and profitability – the risk of vehicle failure should be minimized. To protect the injection system and other engine components, the Bosch filter range is designed for all common commercial vehicle and engine types. In the area of engine management, Bosch offers diesel fuel filters, diesel water separators, coolant filters, air filters, oil filters, oil mist separators and centrifugal oil filters.
Bosch offers cabin filters for over 93% of electric and hybrid vehicles in Europe. This opens up new revenue opportunities for workshops as the number of registered electric vehicles is dynamically increasing.
Possible consequences of a clogged filter:
Bosch recommends changing the cabin air filter every 15,000 kilometers or once a year. The vehicle manufacturer's specifications must also be observed.
The oil filter should always be changed when changing the oil.
To burn one liter of fuel, the engine needs 10,000 liters of clean air. The air filter is responsible for cleaning the air.
