Very close to the front
STAHLGRUBER TRAINING While it sounds cumbersome and dry, “Motorservice/Pierburg - Electrics & Mechanics” was ultimately exactly the opposite: service trainer Achim Villmow's lecture was very close to the front, right in the middle of everyday workshop life.
Very close to the front
Stahlgruber training courses are renowned. According to Stahlgruber Austria CEO Roland Hausstätter, demand in an increasingly complex world is becoming ever greater. In a workshop where the demands are constantly increasing, regular further training is required in order to stay fit. This time the setting was a seminar hotel in Vienna 23. Service trainer Achim Villmow from MS Motorservice brought numerous interested parties up to date on electrical and mechanical systems. The Motorservice Group is the sales organization for Rheinmetall Automotive's global aftermarket activities and is a leading provider of engine components for the independent aftermarket. With the premium brands Kolbenschmidt, Pierburg, TRW Engine Components and BF, Motorservice offers a wide range of products. The trainer sees himself primarily as a “problem solver for the workshop” and is an absolute professional in the following segments: air supply, pollutant reduction and pumps as well as pistons, engine blocks and plain bearings.
TURBOCHARGER
The growing turbocharger market holds great potential for the workshop. “There are more and more vehicles with turbo engines, both diesel and gasoline,” explains Achim Villmow. The proportion will increase from now on, which is related to downsizing, reduction of fuel consumption and reduction of pollutants. “Defects in turbochargers, which are caused by foreign body damage or a lack of lubrication, among other things, make it necessary to replace the turbocharger,” explains the professional. Further potential arises from products related to the turbocharger, such as some Pierburg products, seals or filters, which also have to be replaced when the turbocharger is changed. "The cause of the damage is not always the turbocharger. Malfunctions can be remedied by replacing products in the area without having to replace the turbocharger straight away. For example, vacuum pumps, electro-pneumatic valves," explains Villmow.
ELECTRIC VALVES
According to Achim Villmow, electric valves offer enormous potential for workshops. These are available in the Pierburg aftermarket, not just from car manufacturers. What tasks do electric valves actually have? They are used to operate pneumatic actuators. They are also used to switch between two or more states or allow positions to be moved continuously. This makes them essential components for switching and controlling intake manifolds, exhaust flaps, air conditioning systems, secondary air and EGR valves as well as for implementing comfort and safety functions. The advantages of electric valves are obvious for the service trainer: Electric valves are used in almost all vehicles. Every newer vehicle often has several installed at the same time. Electric valves are monitored directly or indirectly by the OBD system. If these valves fail, repair is essential.

STEEL PISTON
Increasing pressures and high temperatures would place high demands on the pistons of modern engines. “After the first aluminum pistons were switched to steel pistons in the series production of commercial vehicles, this trend has now also arrived in some cars with diesel engines,” says Achim Villmow. Motorservice can be one of the first in the aftermarket to offer steel pistons as spare parts from Mercedes-Benz.
ADVANTAGES
With steel pistons, ignition pressures well over 200 bar and peak temperatures of over 400 degrees are possible. Due to the higher liter output (kW/liter displacement), further downsizing of the engines is possible. The higher strength and temperature resistance of steel allows for very thin-walled constructions. This allows the steel pistons to be designed to be lighter than aluminum pistons. The service trainer comes to the following conclusion: "By using steel pistons, the engine can be made more compact, lighter and more efficient. This efficiency ultimately saves CO2 and helps protect the environment." With the speaker Achim Villmow, Stahlgruber Austria has once again proven that they have a good feel for training very close to the front. The participants completely confirmed our impression.
