AJ126

The #AJ126 is a 3.0 L; 182.8 cu in (2,995 cc) 90° petrol V6, having a bore and stroke of 84.5 mm × 89 mm (3.33 in × 3.50 in) with a 10.5:1 compression ratio. It is supercharged and liquid cooled featuring direct fuel injection, four overhead camshafts and four valves per cylinder. There are two versions differing in power produced, a standard version making 340 hp (254 kW; 345 PS) at 6,500 rpm and 332 lb⋅ft (450 N⋅m) between 3,500-5,000 rpm and a high-performance variant making 380 hp (283 kW; 385 PS) at 6,500 rpm and 339 lb⋅ft (460 N⋅m) between 3,500-5,000 rpm.

The main structural components of the engine are all manufactured from aluminum alloy. The engine is built around a very stiff, lightweight, enclosed V, deep skirt cylinder block. A structural windage tray is bolted to the bottom of the cylinder block to further improve the block stiffness, minimize NVH (noise, vibration and harshness) and help reduce oil foaming. To further enhance the stiffness of the lower engine structure, a heavily ribbed sump body is installed. The sump body also helps to reduce engine noise.

The engine uses a Bosch high pressure direct injection fuel system with fuel pressure provided by two, cam driven high pressure pumps which are driven by a dedicated camshaft. The high pressure pumps supply the fuel rails which in turn supply the three injectors for that bank with fuel at a controlled pressure.

The four camshafts incorporate VCT (variable camshaft timing). VCT allows the timing of the intake and exhaust valves to be adjusted independently of each other. The VCT system is controlled by the Bosch ECM (engine control module) using information from CMP (camshaft position) sensors.

The supercharger is located in the 'vee' of the engine and is driven from the crankshaft by a dedicated secondary drive belt.

The engine meets EU5 emission regulations in Europe and Rest of World (ROW) and ULEV 70 emission regulations in North American Specification (NAS) markets.

The direct fuel injection system, advanced piston and combustion chamber design and the supercharger provide improved fuel consumption and emissions.

The AJ126 V6 is basically an AJ133 V8 engine that has 2 fewer cylinders and is made on the same production line as the AJ133. It shares a very similar block as the supercharged V8 AJ133, with some differences such as reduced bore size. Cylinder heads are also derived from the V8 engine. The engine features a balance shaft to drive the oil pump and balance the crankshaft.

Jaguar is said to be replacing the AJ-126 with an all new Ingenium turbocharged inline-6 engine. It will be smoother, produce substantially more power and burn less fuel.
