V9X engine

The V9X is a common rail V6 turbo-diesel developed by the Renault-Nissan Alliance, and first installed in the Renault Laguna in 2009. It was subsequently made available for all longitudinal-engined vehicles, including Infiniti, Nissan Pathfinder, Nissan Navara, Infiniti FX, Infiniti EX, Infiniti M and Renault Laguna.

Engine power and combustion

The V9X V6 diesel engine develops 170 kW (228 hp) and 550 N·m (410 lb·ft) of torque. Peak torque is achieved from as low as 1,750 rpm to 2,500 rpm, with 500 N·m available from 1,500 rpm. Idle speed is 650 rpm.

The engine has a single turbocharger located within the vee of the engine, fed from both banks and is equipped with an intercooler and Bosch Common rail fuel injection. This system incorporates piezo injectors and operates at 1,800 bar. The combustion chamber design was optimized to improve the balance between emission levels and fuel efficiency; the compression ratio is 16:1
