Engine: Description and Operation

GF01.10-P-0001MCU Mechanical Engine Components, Function

The three-cylinder engine was newly developed from scratch. It is raked to the rear by 45° and installed transversely in front of the rear axle. The engine is characterized by a weight-conscious full aluminum construction from the oil pan to the cylinder head cover. The crankcases are equipped with gray cast iron bushes for the cylinder barrel.

Four valves per cylinder control the gas exchange in the cylinder heads. These are controlled by intake and exhaust camshafts which are driven via a maintenance free timing chain by the crankshaft.

Cup tappets serve as transmission elements for cam contours in the valve movement.

It was possible to dispense with a balance shaft for the three cylinder typical vibrations (free mass moment) because of the low moved masses.

Significant reduction in the tendency to knock was also achieved through optimization of combustion chambers.

The following functions were realized:
^ Camshaft adjustment
^ Air intake
^ Belt drive
^ Engine lubrication
^ Engine cooling
