The number of vehicles equipped with Bosch gasoline direct injection systems is continuously growing. In order to enable workshops to perform repair tasks on these systems, Bosch has 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.

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 hybridisation.

Car manufacturers are currently equipping more and more engines with HDEV6. Bosch says it 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.

For diagnoses and removal of Bosch high-pressure injection valves, the Esitronic 2.0 Online diagnostic software includes error and signal patterns, measured values as well as disassembly and installation instructions.

For this specific purpose, Bosch says it 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.

Bosch will exhibit at next year’s Auto Trade EXPO, which takes place from May 7-8, 2022 at Citywest Exhibition Centre in Dublin.
