Engine: Description and Operation

General
The engine used in this vehicle is of a horizontally opposed, four-cylinder design. This four-strokecycle, water-cooled, SOHC engine uses a total of 16 valves and its main components are made of aluminum alloy. It is fueled by a multiple fuel injection system.
The engine's major structural and functional features are as follows:





^ The cylinder head forms pentroof combustion chambers, each having a spark plug located at its center and two each of intake and exhaust valves (four valves per cylinder). The intake and exhaust ports are located in a cross-flow arrangement.
^ There are a screw and nut at the valve end of each rocker arm. They are used for adjusting the valve clearance.
^ A single timing belt drives two camshafts on the left and right banks and the engine coolant pump on the left bank. Belt tension is automatically adjusted by a belt tension adjuster, eliminating need for a manual adjustment.
^ The crankshaft is supported by five bearings with high rigidity and strength.
^ The cylinder block is an aluminum die casting fitted with iron die-cast cylinder liners.
