High-pressure injection valves
No. 04/2018

Great to work with: High-pressure injection valves

Treating high-pressure injection valves properly enables them to be repaired effectively

Repair of high-pressure injection system components

Bosch supplies spare parts and special tools for the repair of the high pressure injection systems. ESI[tronic] Evolution gives a complete diagnostic sequence to be followed with installation instructions including measurement values, fault patterns and even signal images. With this sort of help from Bosch’s detailed instruction manual, spare parts and special tools, it is a relatively easy task to remove or replace high-pressure injection valves and combustion chamber seals.

Removal and installation of high-pressure injection valve (HPIV)

  • Read ESI[tronic] Evolution instructions carefully
  • Use appropriate tools to remove HPIV and replace the combustion chamber seal
  • Avoid damage to the valve tip (valve leakage)
  • Prevent the ingress of foreign bodies and dirt during installation
  • If the HPIV is to be reused, never use impact tools during the installation of the HPIV into the cylinder head
  • Do not apply oil or grease to the white Teflon seal
  • Apply a thin coat of clean, silicone-free engine oil to the blue seal before installing the fuel rail
  • When removing and reusing the HPIV, always replace the specified spare parts (service kits)

Important Notices

  • The engine must be cold during the repair work
  • The Fuel high-pressure system must be depressurised when working on it
  • Never disconnect fuel lines while the engine is running

‘Step by step’ removal and installation instructions for HPIV and HPP can be found on the Internet

Special tools

  • Set 0 986 616 097 with assembly drift and adjustment ring for installation of the combustion chamber seal
  • For the removal of a high-pressure injection valve:
    • Spindle extractor 0 986 616 100
    • Impact extractor 0 986 616 101 (only use when valves are seized)

Spare parts

  • O-ring for high-pressure injection valve (HPIV)
  • Combustion chamber seal (Teflon ring)
  • Support shim
  • Hold-down tool

Bosch air filters
No. 03/2018

Bosch air filters

Explore product characteristics and customer benefits

Terminus for particles of dirt of all kinds

The tasks of an air filter are to protect the motor from particles of dirt in the entrained air, to protect the motor from abrasive wear and to assure the supply of air for air/fuel mixture preparation.

Regularly change the air filter according to the vehicle manufacturer’s instructions!

Consequences of a clogged filter:

  • Reduced air intake, leading to decreased engine output and increased pollutant emission
  • Higher fuel consumption
  • Problems when starting the engine
  • Premature oil contamination

Quality is worth paying for. Find a comparison of Bosch air filters here:

Aerotwin passenger car flat-blade wipers

Bosch Aerotwin: leading technology in the field of flat-blade wipers

Bosch Aerotwin

Development and innovation

Maximum comfort, trailblazing design

All components are developed based on specific vehicles, and cutting-edge tools are used to fine-tune the wiper system.

Bosch uses the wind tunnel to perform tests under various wind conditions and speeds up to 160 km/h, for instance.

Large-scale manufacturing

Special, multi-award-winning Bosch rubber mixture

Consistently high rubber mixture production quality thanks to sophisticated lab analyses prior to production approval.

The wiper rubber is durable due to its high resistance to abrasion, UV light and aging as well as high cold and heat elasticity.

Performance and stress testing

Safety and reliability are the foremost principles

Strict performance and stress tests carried out in the testing laboratory as well as directly on the vehicle are the basis for the consistently high quality of Bosch windscreen wipers.

Subject to testing are, among others, resistance to environmental and ozone impacts, chemical stress and abrasion.

Performance tests assess wiping quality, noise generation, high-speed performance and service life to ensure long-lasting wiping quality.

Cabin filters

Quality testing of the FILTER+ cabin filter

FILTER+ cabin filter

Quality testing: Filtration efficiency

An important quality criterion for a cabin filter’s performance is its filtration efficiency or its capacity to filter out particles. Bosch had its FILTER+ and a similar OE filter tested by the independent institute Flatech GmbH, Germany. Measurements were made in accordance with ISO 11155-1.

Test results*

Particulate matter test:
Bosch’s FILTER+ offers highly efficient protection against respirable particulate matter (particle size < 2.5 μm), surpassing even a similar OE filter.

Pollen test (ragweed and birch):
Bosch’s FILTER+ provides the same high degree of efficient protection against allergens as a similar OE filter.

Cabin filter range
Workshop Tip

Bosch recommends that you change the cabin filter once a year or every 15,000 km.

Consequences of a clogged filter:

  • Reduced vision from fogged windows, resulting in reduced safety
  • Increased pollutant concentration inside the vehicle
  • Allergic reactions, e.g. sneezing
  • Reduced cooling capacity of the air-conditioning system resulting from deposits on the evaporator
