NR20DE

The NR20DE is a four-cylinder, 2.0-liter internal combustion engine manufactured by Nissan. It is part of Nissan's NR engine family, which is known for its focus on fuel efficiency and emissions reduction. The NR20DE features a cast-iron block and an aluminum cylinder head. It employs a DOHC (Double Overhead Camshaft) valvetrain and utilizes Nissan's Variable Valve Event and Lift (VVEL) technology, which electronically controls valve timing and lift for improved performance and efficiency across the engine's operating range.

This engine typically utilizes a naturally aspirated induction system, meaning it does not have a turbocharger or supercharger. It is also designed to be compatible with gasoline fuel. Fuel delivery is generally handled by a multi-point fuel injection system. The NR20DE is often found in a variety of Nissan and Infiniti vehicles, commonly used in compact and mid-size sedans and SUVs. Its design prioritizes a balance of power, fuel economy, and lower emissions, making it a suitable choice for mass-produced passenger vehicles.
