This engine family is intended to complement and later replace the N45 and N46 families. Of the latter, the N43 family incorporates various characteristics, including:
4- cylinder in-line architecture ;
cylinder head with 4 valves per cylinder;
distribution with two overhead camshafts ;
presence of the Vanos double variable valve timing system.
The continuous valve timing system Valvetronic is also taken over from the N46 family.
The novelty proposed by the N43 family is the direct injection power supply, called HPI ( High Precision Injection ), which ensures better combustion of the air / petrol mixture inside the combustion chambers.
The small N43 family consists of a 1.6-liter and a 2-liter version, the latter available in three power variants.
