3.2L Engine : Engine mechanical
The V6 engine features a closed V, deep skirt die cast aluminiumcylinder block with cast iron cylinder liners, internally balanced crankcase, full length water jackets and six bolt main bearing caps.The cylinders are arranged in two banks of three with a 60 degree included angle between the two banks. The rear bank of cylindersconsists of number 1–3–5 cylinders (BANK 1) and the front bank of cylinders consists of number 2–4–6 (BANK 2).The engine firing order is 1–2–3–4–5–6. Each aluminium cylinder head is fitted with hardened valve seats and four valves per cylinder: two intake and two exhaust. The valves are operated by two camshafts (DOHC) per cylinder bank, one each for intake and exhaust valves. Variable camshaft timing is provided via four actuators fitted at thefront of each camshaft.The crankshaft is manufactured from forged steel. A reluctor wheel is pressed in place onto the rear of the crankshaft for the crankshaft position sensor.The connecting rods are manufactured from powdered metal and the rod cap is separated during the manufacturing process using the fractured method. This creates a stronger, visually seamlessrod to cap union.
Features and Benefits• Dual Continuously Variable Cam Phasing
(Reduced fuel consumption, increased performance)• 24-Valve Cylinder Head
(Improved performance due to increased air flow)• Closed Coupled Catalytic Converter (Achieve Euro 4 limits)• Electronic Throttle Control (Improved drive ability comfort)• Roller finger follower and hydraulic valve lash adjuster
(Low friction, maintenance-free valve train)• Chain Drive Timing System (life-time maintenance free)• Poly-V-Belt Accessory Drive with automatic Belt Tensioner

The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the main fuel pump module.An electric turbine style fuel pump attaches to the main fuel pumpmodule inside the fuel tank. The fuel pump supplies high pressure fuelthrough the fuel filter, past the fuel pressure regulator, and through thefuel feed pipe to the fuel injection system. The fuel pressure regulator as a T-joint that diverts the needed fuel to the fuel rail with the unused fuel dropping back into the reservoir of the main fuel tank module. The main fuel pump module contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times.

Fuel tank
The fuel tank stores the fuel and the tank is sealed up leakage of vapor. The fuel tank is made from high density polyethylene. The main fueltank is located in the rear of "Front muffler"and under the body of thevehicle. The fuel tank are each sides held in place by 2 metal strapsthat is able to hold from two nuts attach to the frame. The fuel in the tank supplies to the engine through the supply line by the pump.The vapor that is produced in the tank is going through the line by Rollover valve and Grade vent valve, vapor pressure in the tank is discharged to the Canister and it doesn't make the tank over.

Fuel Level Gage ControlThe fuel level sensor changes resistance in response to the fuel level. The engine control module (ECM) monitors the signal circuit of the fuel level sensor in order to determine the fuel level. When the fuel tank is full, the sensor resistance is low and the ECM senses a low signal voltage.When the fuel tank is empty, the sensor resistance is high and the ECM senses a high signal voltage. The ECM uses the signal circuit of the fuel level sensor in order to calculate the percentage of remaining fuel in the tank.
The fuel level signal is sent to ECM, the ECM sends the message of the fuel level to the BCM and the BCM modulates fuel level gauge inthe cluster by single wire CAN.

The evaporative emission canister is an emission control device containing activated charcoal granules. The evaporative emissioncanister is used to store fuel vapors from the fuel tank. Once certain conditions are met, the electronic control module (ECM) activates the controlled canister purge solenoid allowing the fuel vapors to be drawn into the engine cylinders and burned.
