Toyota Car Parts - 3S-GTE Engines

The pistons are made from an aluminum alloy, design to withstand high temperatures Due to the design of the intake manifold, cylinder number 3 runs lean under normal operation 8:1 depending on generation Spark plugs are located in the middle of the combustion chambers A panel is used to ensure that there are sufficient oil available in the oil pan, as the oil moves around the reservoir during movement of the vehicle It was fitted to the MR2 , Toyota Celica GT-Four, and the Caldina. The crankshaft, located within the crankcase, rotates on 5 aluminum alloy bearings and is balanced by 8 weights To adjust the valve clearance, adjust the shims above the valve lifters (shim over bucket system) A distributor based system is used to fire the cylinders in a 1-3-4-2 order This allows for the replacement of the shims without the need to remove the camshaft The third generation uses a normal 4-runner intake manifold The cam journals are lubricated by oiler port located in the middle of the camshaft There are four generations of this engine, which started manufacture in 1986, and continues to the current day. Built into the cylinder block are coolant channels, which cools the block which houses the crankshaft The Dual Over Head Cam (DOHC) 16 valve cylinder head designed by Yamaha is made of aluminum alloy. At the bottom of the cylinder block is an oil pan which stores the oil A single timing belt drives the intake and exhaust camshaft along with the oil and water pumps. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and various other components. The 1st and 3rd Celica generation intake charge was cooled by a Water to Air intercooler while the 2nd, 3rd MR2, and 4th generation relied on an Air to Air system. The 3S-GTE is an in-line 4-cylinder 1998cc engine from Toyota, based on the 3S-GE with reduced compression ratio and addition of a turbocharger. The pent-roof combustion chambers are complemented by a cross flow intake and exhaust layout. The first and second generations used the Toyota CT26, although the second-generation turbo was modified for increased reliability. The 1st compression ring and the oil ring is made of steel, the 2nd compression ring is made of cast iron. The cam journal is supported on 5 points between the valve lifters of each cylinder and on the front of the cylinder head. Compression ring 1 and 2, prevents gas leakages from the combustion chamber while the oil ring works to clear oil off the cylinder walls, preventing any excessive oil from entering the combustion chamber.
