TheV9X is a common rail 65 degree V624-valveDOHCturbo-diesel developed by theRenault-Nissan Alliance, and first installed in theRenault Laguna in 2009. It was subsequently made available for both longitudinal-engine vehicles includingNissan Pathfinder,Nissan Navara,Infiniti FX,Infiniti EX, andInfiniti M and transverse-engine vehicles includingRenault Latitude andLagunaCoupé. It was the first diesel engine installed in any Infiniti automobiles, seen as a necessity as that brand attempted to enter the European market.[1]
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 anintercooler and BoschCommon rail fuel injection. This system incorporates piezo injectors and operates at 1,800 bar (26,000 psi). Thecombustion chamber design was optimized to improve the balance betweenemission levels andfuel efficiency; the compression ratio is 16.0:1.
When fitted to the Infiniti EX30d, the V9X engine emits 224 g (7.9 oz)/km ofCO2 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]
It is fitted to the following vehicles:
