The QD32Ti engine features a cast-iron cylinder block for durability and strength.
It utilizes an overhead camshaft (OHC) design with four valves per cylinder, allowing for efficient intake and exhaust flow. The engine is equipped with a turbocharger, which helps improve power output by forcing more air into the combustion chamber.
In terms of specifications, the QD32Ti engine produces a maximum power output of around 98 horsepower (73 kW) at 3,600 revolutions per minute (RPM). It generates a peak torque of approximately 192 lb-ft (260 Nm) at 2,000 RPM. These figures provide the engine with sufficient power and torque for hauling heavy loads or tackling challenging terrain.
The QD32Ti engine features an indirect fuel injection system, which sprays fuel into pre-combustion chambers. This design enhances fuel atomization, improving combustion efficiency and reducing emissions. The engine also incorporates a swirl control valve, which helps optimize air intake for better combustion and fuel economy.
To meet emission regulations, the QD32Ti engine is equipped with a range of emission control technologies. It includes an exhaust gas recirculation (EGR) system, which reintroduces a portion of the exhaust gases back into the combustion chamber to lower combustion temperatures and reduce nitrogen oxide (NOx) emissions. Additionally, the engine incorporates a diesel particulate filter (DPF) to capture and remove particulate matter from the exhaust gases.
The QD32Ti engine is known for its reliability and durability. It has a long service life and is capable of enduring heavy usage. Regular maintenance, including oil changes and filter replacements, is essential to ensure the engine's longevity and optimal performance.
In terms of fuel efficiency, the QD32Ti engine offers respectable figures for its class.
Its fuel consumption varies depending on factors such as vehicle weight, driving conditions, and load capacity. However, it generally delivers decent fuel economy, especially when compared to larger displacement engines.
The QD32Ti engine has found applications in various Nissan vehicles, including the Nissan Patrol and Nissan Terrano. Its torquey nature and robust construction make it suitable for off-road and commercial use. Whether towing heavy loads or navigating challenging terrain, the engine provides the necessary power and reliability.
