In 2023, more than half of approved combustion engines will be equipped with gasoline direct injection (GDI) systems.As a result, the demand for repair and maintenance for this type of engine will also grow.The number of vehicles equipped with Bosch petrol direct injection systems is also growing steadily.To enable workshops to carry out repairs on these systems, Bosch is expanding its aftermarket offering to include Bosch HDEV6 high-pressure injectors.Evolution of the HDEV5, the HDEV6 injectors represent the latest generation technology in terms of high pressure injectors and are designed for nominal injection pressures up to 350 bar.Gasoline direct injection engines stand out for their high performance combined with low fuel consumption and emissions.Engine developers are also choosing direct petrol injection for the combustion engines of the new hybrid propulsion systems.The market linked to the already large number of direct injection systems in use will continue to grow precisely by virtue of hybridization.Car manufacturers are equipping more and more engines with HDEV6.Bosch supports workshops by providing the know-how, repair kits and suitable spare parts, such as the recently included HDEV6.Garages will therefore be able to increase their revenue potential by taking advantage of this market.For diagnostics and removal of Bosch high-pressure injectors, the Esitronic 2.0 Online diagnostic software includes a number of important information, including errors and signal sequences, measured values and instructions for disassembly and installation.For example, if a high-pressure injector needs to be reinstalled after ultrasonic cleaning, the seals must be replaced, among other things.For this specific purpose, Bosch has developed the BTG 5120 tool kit: a kit that allows the professional replacement of the Teflon sealing ring of the combustion chamber, the O-ring and the decoupling elements of almost all fuel injectors. type HDEV5 and HDEV6.The compact carrying case includes a pair of special pliers, sleeves and calibration pins.
