All the details.


Diesel engine

The diesel engine is a piston engine with internal mixture formation and autoignition. Due to the high compression, the air temperature in the combustion chamber rises from 600 to 900°C. After the fuel has been injected, the fuel-air mixture ignites by itself.

Diesel engines operate with different injection methods: pre-chamber, swirl chamber or direct injection. SEAT models only use modern diesel engines with direct injection. They are characterised by low fuel consumption, low emissions, high efficiency and long service life.

SEAT's TDI® engines also come with turbocharging. This method further increases power and torque while maintaining engine capacity and revolutions.
