The V9X is a common rail 65 degree V6 24-valve DOHC turbo-diesel developed by the Renault-Nissan Alliance, and first installed in the Renault Laguna in 2009. It was subsequently made available for both longitudinal-engine vehicles including Nissan Pathfinder, Nissan Navara, Infiniti FX, Infiniti EX, and Infiniti M and transverse-engine vehicles including Renault Latitude and Laguna Coupé. the v9x engine is based on the p9x engine,It was the first diesel engine installed in any Infiniti automobiles, seen as a necessity as that brand attempted to enter the European market.

Engine power and combustion

The V9X V6 diesel engine develops 170 kW (231 PS; 228 hp) and 550 N⋅m (406 lb⋅ft) of torque. Peak torque is achieved from as low as 1,750 rpm to 2,500 rpm, with 500 N⋅m (369 lb⋅ft) 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 (26,000 psi). The combustion chamber design was optimized to improve the balance between emission levels and fuel efficiency; the compression ratio is 16.0:1.

Emissions and fuel consumption

When fitted to the Infiniti EX30d, the V9X engine emits 224 g (7.9 oz)/km of CO2 and returns a combined fuel figure of 8.4 L/100 km (34 mpg‑imp; 28 mpg‑US). When fitted to the Nissan Navara 4x4, it emits 246 g (8.7 oz)/km of CO2 and returns a combined fuel figure of 9.6 L/100 km (29 mpg‑imp; 25 mpg‑US). [2]
