Purpose and function in a diesel engine

The presented intake manifold integrated with the breather and oil separator is designed for Diesel power units used in Renault Trafic 3 models and structurally similar Vivaro B vehicles. Its task is to evenly distribute air to the cylinders while discharging gases from the crankcase and limiting the amount of oil entering the intake system. As a result, the combustion system maintains stable operating conditions, and the accumulation of deposits in the intake ducts can be reduced.

Combining the intake and breather functions into a single assembly promotes compact installation in the engine bay, which facilitates service and diagnostics. For the user, this means the possibility of replacing the entire assembly in one process, without the need to match several separate elements.

Construction of the intake manifold + breather + oil separator assembly

The assembly includes the part responsible for supplying air to the cylinders and the breather system with an oil separator, which is designed to separate oil mist from gases before they return to the intake. This configuration helps maintain more predictable engine operating conditions, especially in diesel units where air quality and crankcase pressure stability are significant for smooth operation.

This solution is particularly beneficial in vehicles used intensively, where the intake system is exposed to increased thermal and mechanical loads. Using a complete assembly allows for consistent matching of the shape of the intake ducts and the flow in the breather system, which makes it easier to maintain operating parameters in accordance with the manufacturer's specifications.

Benefits of using an OEM part

As a component originating from the Renault manufacturer's line, the intake manifold with breather and oil separator ensures factory-fit for the power units used in the Renault Trafic 3 and Vivaro B. The proper arrangement of ports, channels, and mounting points translates into correct alignment with other components in the engine bay, without the need for installation modifications.

Choosing a used OEM component is a cost-effective solution while maintaining the original geometry of air and breather gas flow. For workshops and individual users, this means the ability to restore the proper operation of the intake system and breather in accordance with factory specifications, which is important, among other things, when solving problems with unstable engine operation, excessive smoke, or oil contamination of the intake.

Selection and application in service practice

When selecting this assembly for a Renault Trafic 3 or Vivaro B, it is crucial to verify compatibility with the specific diesel engine version and compare the design of the element with the one currently installed in the vehicle. The product has assigned catalog and replacement numbers, which facilitates identification in parts catalogs and service systems, and minimizes the risk of installing an incorrect variant.

In workshop practice, replacing the complete intake manifold assembly with a breather and oil separator is often recommended in situations where leaks, excessive duct contamination, or problems with discharging gases from the crankcase are identified. Using a single, cohesive element simplifies the assembly process and reduces the number of potential failure points.
