Latest Bosch HDEV6 high-pressure injection valve is now also available on the aftermarket - Growing aftermarket business related to maintenance and repair of gasoline direct injection engines

• Latest generation of high-pressure injection valve technology complements the Bosch aftermarket range
• Growing number of vehicles with direct injection systems due to hybridization
• Modern repair concepts, spare parts and the new BTG 5120 tool kit for professional servicing of high-pressure injection valves

Karlsruhe - In 2023, more than half of all newly approved combustion engines will be equipped with gasoline direct injection (GDI) systems. As a result, there is also a growing demand for repair and servicing of GDI engines. The number of vehicles equipped with Bosch gasoline direct injection systems is also continuously growing. In order to enable workshops to perform repair tasks on these systems, Bosch now expanded its aftermarket range with DEV6 high-pressure injection valves. Following on from HDEV5, it is the latest generation of high-pressure injection valve technology. HDEV6 high-pressure injection valves are designed for nominal injection pressures of up to 350 bar.

Additional growth through hybrid powertrain concepts

Gasoline direct injection engines stand out for their high performance combined with low consumption and emissions. Engine developers also rely on gasoline direct injection systems for the combustion engines of hybrid powertrain concepts. The market related to the large amount of direct injection systems already in operation will continue growing thanks to powertrain hybridization. Car manufacturers are currently equipping more and more engines with HDEV6. Bosch supports workshops providing know-how, repair kits and suitable spare parts – such as the most recently included HDEV6. This allows automotive workshops to increase their turnover potentials benefiting from this growing service market.

Professional repair using BTG 5120 tool kit

For diagnoses and removal of Bosch high-pressure injection valves, Esitronic 2.0 Online diagnostic software includes error and signal patterns, measured values as well as disassembly and installation instructions. In case, a removed high-pressure injection valve is to be reinstalled after ultrasonic cleaning, for instance, among other things, the seal rings need to be replaced. For this specific purpose, Bosch developed the BTG 5120 tool kit. It allows professional replacement of combustion chamber sealing ring (Teflon seal), O-ring and decoupling elements of almost any HDEV5- and HDEV6-type injection valve. The compact case comprises a special pair of pliers, calibration sleeves and pilot cones. Furthermore, there are also Bosch-produced video instructions available online which explain the removal and installation of high-pressure injection valves.
