Bosch highlights “complete GDI proposition” for garages

Comprehensive aftermarket GDI parts programme backed with diagnostics and training

As ever more vehicles with GDI systems enter the market, workshops are increasingly turning to OE supplier Bosch for their servicing and repair needs, the company has said.

GDI is a key technology in the latest generation of ultra-efficient gasoline vehicles, delivering improved performance, increased economy and enabling engine downsizing.

Modern GDI systems feature low pressure and high pressure circuits, with an electric fuel pump supplying a high pressure pump (HDP) with gasoline at around 6 bar.

The HDP compresses it up to 200 bar and feeds it to the fuel rail, where high pressure injectors push precise quantities of perfectly-mixed fuel directly into the combustion chamber.

Growing service market

By the end of 2019, there will be around four million cars on UK roads with direct injection gasoline engines, and this number is expected to double within a few years.

To meet rapidly increasing demand, Bosch has created a complete GDI service solution for the automotive aftermarket, including components developed for the best racing teams in the world, state-of-the-art diagnostic solutions and industry benchmark training.

Bosch GDI parts

As a pioneer in the technology, Bosch has sold over 11 billion spark plugs since 1902.

It is technical partner to the most prestigious international motorsport championships and successful innovations are constantly adapted for volume production.

The aftermarket is therefore the ultimate beneficiary of Bosch’s combined motorsport and OE know-how.

GDI spark plug tip

When installing spark plugs in GDI engines, the alignment of the side electrode in relation to the spray nozzle is critical. Installing the correct spark plug, with the right tooling and torque, is crucial for optimum engine function.

Bosch modern compact, pencil and multi-spark coils are all incredibly resistant to heat, vibration and corrosion, delivering exceptional performance and reliability.

High pressure injectors and pumps are vital components of today’s electronically-controlled GDI systems – technology which has been refined over many decades of research and development.

A 2.5-litre Mercedes-Benz with a 500 bar Bosch mechanical direct gasoline injection system famously won the French Grand Prix way back in 1954.

Invented by Bosch in 1976, Lambda sensors have made a significant contribution to meeting today’s demanding emissions standards.

To date, Bosch has produced more than one billion Lambda sensors.

Its high quality aftermarket range covers 85 per cent of the UK car parc, with pre-greased threads for ease of fitment.

Morten Jensen, Bosch product specialist for gasoline, Europe North, said: “The GDI car parc is growing fast and, with our motorsport and OE credentials, independent workshops look to Bosch for parts, equipment and training.

“The widespread use of Bosch ignition and GDI components in motorsport serves as a real-life rolling test lab.

“A great example is platinum alloy spark plug electrodes, first used in the 1970 Le Mans-winning Porsche 917.

“Unlike the previous generation of passenger car gasoline engines, which allowed for only an approximate mixture of gasoline and air, GDI enables an extremely precise blend with optimised and variable spray timing under different load conditions.

“Bosch offers a comprehensive range of parts with great market coverage and, as proven on the road and racetrack, repairers and drivers can trust both the quality and reliability.”

Bosch ESI[tronic] 2.0 online diagnostic software and training

Bosch’s development expertise, technical quality and reliability are also reflected in its diagnostic software, which will increase the efficiency and effectiveness of everyday workshop tasks.

Today’s technicians expect more than just control unit diagnostics, whether for passenger cars or commercial vehicles.

Intelligent troubleshooting and support for rapid repair and maintenance according to the manufacturer’s specifications are the new standard and all these requirements are met with ESI[tronic] 2.0 online.

ESI[tronic] 2.0 online technicians through the process step-by-step and the experience based repair (EBR) functionality provides instant access to known faults and reliable solutions.

The perfect hardware partners are the new generation Bosch KTS tools featuring ethernet-based interfaces for super-fast data transfer.

In terms of training, Bosch’s VSG11 GDI system diagnosis course will significantly improve technician efficiency.

On successful completion, technicians will fully understand a typical Bosch GDI system and be able to utilise serial diagnosis and oscilloscope data to quickly determine the required system or component repairs.

The course forms part of a comprehensive modern vehicle technology training programme, designed by Bosch specifically for independent workshops in the UK.
