Toyota Car Parts - 3S-GE Engines

Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt The crankshaft, located within the crankcase, rotates on five aluminium alloy bearings and is balanced by eight weights This is sometimes referred to as a 'non-interference' engine The 'Outer Shim Type System' allows for the replacement of the shims without the need to remove the camshaft The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron The ignition order of the cylinders is in the 1-3-4-2 order. This prevents oil from being shifted away from the oil pump suction pipe A single timing belt drives the intake and exhaust camshaft The top of the cylinders are covered by the cylinder head The cylinder heads are made of aluminium alloy. The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout. To adjust the valve clearance, adjust the shims above the valve lifters. The cam journals are lubricated by an oiler port located in the middle of the camshaft. All 3S-GE engines had a displacement of 2 The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head. Compression rings 1 and 2 prevent exhaust leakage from the combustion chamber while the oil ring works to clear oil off the cylinder walls, preventing excessive oil from entering the combustion chamber. The cast iron cylinder block holds four cylinders which are approximately two times the length of the piston stroke. An indentation is incorporated into the piston head to prevent the pistons from hitting the valves, should the timing belt break (this is not true of the 3S-GE BEAMS motor). 0 L.
