Toyota Car Parts - 3S-GE Engines

Additionally, the 3S-GTE engines were based on the 3S-GE designs The pistons are made from an aluminium alloy, designed to withstand high temperatures Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt. 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 A single timing belt drives the intake and exhaust camshaft The cam journals are lubricated by an oiler port located in the middle of the camshaft This prevents oil from being shifted away from the oil pump suction pipe The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head Built into the cylinder block are coolant channels, which cool the block which houses the pistons This is sometimes referred to as a 'non-interference' engine Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components. The spark plug is located in the center of the combustion chamber. 0 L There are four generations of the 3S-GE, which were used in the Toyota Celica, MR2, Toyota Caldina, Toyota Altezza and Lexus IS200 The cylinder heads are made of aluminium alloy. The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron. To adjust the valve clearance, adjust the shims above the valve lifters. The crankshaft, located within the crankcase, rotates on five aluminium alloy bearings and is balanced by eight weights. All 3S-GE engines had a displacement of 2. 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).
