Direct Petrol Injection System with Bosch Motronic MED 7 - Self-Study Programme 253 PDF

Direct Petrol Injection System with Bosch Motronic MED 7 – Self-Study Programme 253 PDF. In this Self-Study Programme we will show you the component parts of the direct petrol injection system together with the Bosch Motronic MED 7 used in the Lupo FSI and Golf FSI.

The primary objective of engine development is to minimise fuel consumption and exhaust emissions. A closed-loop catalyst reduces emission of hydrocarbons, nitrogen oxides and carbon monoxide by up to 99%.

However, the emission of carbon dioxide (CO2), a greenhouse gas produced by combustion, can only be reduced by lowering fuel consumption. But this is hardly feasible in systems with external mixture formation (intake manifold injection systems).

This is why engines equipped with the Bosch Motronic MED 7 direct petrol injection system will be used for the first time in the Lupo FSI and Golf FSI.

They have the potential to reduce fuel consumption by up to 15% compared to a similar engine with intake manifold injection.

This Self-Study Programme explains the design and function of new developments.
Please refer to the relevant Service Literature for up-to-date inspection, adjustment and repair instructions.
