The Nissan ZD30 engine features a cast iron block with a single overhead camshaft design.

It utilizes a direct injection fuel system, which helps improve fuel atomization and combustion efficiency. The engine is equipped with a turbocharger, which provides forced induction and enhances power output. The turbocharger helps the engine generate higher torque at lower RPMs, making it suitable for both off-road and on-road applications.

The ZD30 engine is available in both naturally aspirated and intercooled turbocharged variants. The intercooled version, known as the ZD30DDTi, is the more common configuration. It includes an air-to-air intercooler, which cools the compressed air from the turbocharger before it enters the combustion chamber. This helps increase the density of the intake air, resulting in better combustion and improved power output.

In terms of power, the ZD30 engine produces around 120 to 160 horsepower, depending on the specific variant and model it is installed in. The torque output ranges from approximately 280 to 380 Nm, offering sufficient low-end grunt for towing and off-road performance. The engine's power and torque characteristics make it suitable for a variety of applications, including hauling heavy loads and navigating challenging terrains.

The ZD30 engine features a robust construction and is known for its reliability. However, it has faced some issues related to its early iterations, such as premature failure of the timing chain and injector pump failures. These issues were addressed in later versions of the engine, and proper maintenance and regular servicing are essential to ensure longevity and prevent potential problems.

In terms of fuel efficiency, the ZD30 engine offers commendable mileage, particularly for a diesel engine.

It benefits from the inherent fuel efficiency of diesel powertrains, allowing for longer driving ranges on a single tank of fuel. This makes the engine suitable for long-distance travel and applications where fuel economy is a priority.

The ZD30 engine is designed to meet emissions regulations and incorporates various technologies to reduce pollutants. It utilizes an exhaust gas recirculation (EGR) system, which recirculates a portion of the exhaust gases back into the engine's intake system. This helps lower nitrogen oxide (NOx) emissions, contributing to cleaner combustion.
