Diesel direct injection

In diesel direct injection, fuel is injected directly into the combustion chamber. The direct injection diesel engine is currently the most efficient engine thanks to its high efficiency factor.

In diesel direct injection, there are various ways to optimise the combustion process. These days, the common rail and pump-line-nozzle system have become established, along with the pump-jet system.

All SEAT models offer diesel direct injection using the common rail system.
