Technical Service


Technical services for EU type approval of passenger cars

Bosch Engineering Technical Service is an independent Technical Service within the Bosch Engineering GmbH designated by the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt – KBA) according to DIN EN ISO/IEC 17025 and 17020.
We carry out the official EU type approval for the following fields of testing within the powertrain area: Engine power, emissions and OBD, fuel consumption and diesel smoke – either at our own state-of-the-art test facilities or at your location.
We accompany you throughout the entire certification process: beginning with the initial assessment by the KBA, to carrying out all relevant measurements as well as preparation of the test report, to acquire the certificate from the authority.
In addition, at our customers' request we carry out the legally required inspections for the Conformity of Production (CoP) measurements according to series production within the tendering model by the KBA.

Our individual services are:

Engine power certification (R85)

The engine is inspected from the minimum speed to the maximum speed, according to the manufacturer's specifications. The manufacturer's advised rated capacity as well as the working point with the largest torque is approached. The type approval is according to reg. (EC) 715/2007 (UN/ECE-R85) and comprises:

  • Measuring the engine power of combustion motors to power motor vehicles
  • Measuring the effective power and the highest "30 minute performance" of electrical drive systems
  • Determination of the motor's power curve on the dynamometer

Emission and OBD certification (R83)

We measure the pollutant emissions from the engine and check the vehicle's on-board diagnostics (OBD) system. The type test is according to reg. (EC) 715/2007 (UN/ECE-R83).

Emission measurement:

  • Type I: Emissions after a cold start (20°C)
  • Type II: CO emissions in idle mode
  • Type III: Emissions from the crankcase
  • Type IV: Evaporative emissions
  • Type V: Durability
  • Type VI: Emissions at low temperatures (-7°C) after a cold start
  • Emissions data definition for in-use tests
  • Real Driving Emissions (RDE) with a Portable Emission Measurement System (PEMS)

OBD inspection:

  • In order to individually test the diagnostic capability, the vehicle is fitted with different systems and components with errors.
  • The test has been passed when the diagnoses to be tested according to the tests recognize all errors before the end of the test cycle, display them, and the emissions are below the legally defined limit

Fuel consumption certification (R101)

Here the CO2 and fuel consumption and/or electricity consumption are measured, as well as the electric range of passenger cars, which are driven by a pure combustion motor, a purely electrical engine or with hybrid technology. The test on your vehicle is carried out on the dynamometer and the type approval is according to the reg. (EC) 715/2007 (UN/ECE-R101).

Diesel smoke certification (R24)

We test your vehicle for approval of engines with self-ignition (diesel engines) regarding the emissions for visible, air-polluting substances, direct on the dynamometer. The type approval is according to reg. (EC) 715/2007 (UN/ECE-R24).
