What is a VTG controller and why is it so important? A VTG (Variable Turbine Geometry) controller is a component that controls the geometry of the blades in a variable geometry turbocharger. Its task is to regulate the angle of the air deflectors, which allows for optimal adjustment of the amount of exhaust gas flowing […]

How does the transmission selector work and why is it crucial? The gearbox selector is one of the essential components of the transmission system in trucks, enabling efficient gear changes. Its correct operation has a direct impact on vehicle performance, driving comfort and driver safety. This mechanism can be manual, electronic or hydraulic, and each

What is an EGR exhaust gas cooler and why is it so important? The EGR exhaust gas cooler is a basic component of the exhaust gas recirculation system, which is designed to reduce nitrogen oxide (NOx) emissions by cooling down some of the exhaust gases that are recirculated into the combustion chamber. This lowers the

Turbocharger is an important component of the intake system in modern internal combustion engines. Its role is to increase engine power by supplying more air into the combustion chamber. The result? Better performance and more efficient fuel combustion. Over time, however, this component can wear out, affecting the performance of the drive unit. When performance

What is the function of the BPV valve in the intake system? The BPV (Back Pressure Valve) is a component in the intake system of turbocharged vehicles. Its main task is to regulate the air pressure in the intake manifold and protect the turbocharger from sudden pressure spikes that could lead to damage.   It

What is a VTG adjuster and what is its function? VTG (Variable Turbine Geometry) adjuster is a control element in turbochargers with variable blade geometry. Its function is to regulate the flow of exhaust gas through the turbine, thereby optimizing engine operation, reducing turbo hole and improving performance. It works on the principle of a

Winter is a difficult time for trucks – low temperatures, moisture, road salt and icy surfaces increase the risk of failure. In such conditions, cooling system components such as liquid coolers, air coolers (intercoolers) and exhaust gas recirculators (EGR) are particularly vulnerable to damage.   Liquid coolers – risk of fluid freezing Liquid coolers keep

The turbocharger is a very important part of the drivetrain, which affects engine performance and fuel economy. However, like any mechanical part – it wears out over time, which can lead to a drop in power, higher combustion and more serious malfunctions. Early detection of symptoms allows you to avoid costly repairs and vehicle downtime,

Choosing the right Scania truck spare parts affects the safety, performance and reliability of your vehicle. The right choice means longer part life, lower operating costs and less risk of failure. That’s why it pays to know what to look for when buying and the advantages of remanufactured components.   Genuine Scania parts Genuine Scania

The selection of an intercooler has a direct impact on the performance and durability of a truck engine. The charge air cooler is important in the combustion process, and its quality affects engine performance. Therefore, it is worth knowing what to pay attention to when choosing this component and what benefits are provided by remanufactured
