BMW 116/118 F20 N13 engine

Description

Overview
The BMW N13B16A is a 1.6-liter turbocharged inline-four petrol engine developed as part of BMW’s N13 engine family. Designed to deliver efficient, downsized performance, the N13B16A replaced larger naturally aspirated engines in BMW’s compact lineup. It combines direct fuel injection, a twin-scroll turbocharger, and variable valve control to provide responsive power with low fuel consumption and reduced emissions. Lightweight and compact, this engine was built to meet strict efficiency targets while maintaining the driving feel expected in a BMW.

Key Features
1.6L Turbocharged Inline-Four Engine – With a displacement of 1,598 cc, the N13B16A delivers strong low- to mid-range torque and efficient performance in a compact, lightweight form.
Twin-Scroll Turbocharger – The integrated twin-scroll turbo improves boost response and reduces lag, allowing the engine to produce usable torque across a wide RPM range.
Direct Fuel Injection – High-pressure direct injection ensures precise fuel delivery, improving combustion efficiency and reducing both emissions and fuel consumption.
Double VANOS & Valvetronic – The engine uses BMW’s fully variable valve timing (double VANOS) and variable valve lift (Valvetronic) for optimized airflow and responsiveness under all load conditions.
Aluminum Engine Block and Head – Both the block and cylinder head are made from aluminum alloy to reduce weight and improve heat dissipation.
Chain-Driven Camshafts – The N13B16A uses a timing chain system for long service life and reduced maintenance compared to timing belt setups.
Closed-Deck Block Design – The block structure improves rigidity and supports higher internal pressures associated with turbocharged operation.

Performance & Applications
The N13B16A was used in several compact BMW models where a balance of efficiency and performance was required in a smaller engine configuration.
Factory-installed in the following BMW models:

• F20/F21 116i / 118i (2011–2015)

• F30/F31 316i (2012–2015)

• F10 520i (select regions, detuned version)

• BMW E82/E88 114i (certain late production markets)

Note: Power output varied slightly between models due to ECU calibration and tuning differences, but the core engine hardware remained the same.
