Toyota Car Parts - 3S-GE Engines

The ignition order of the cylinders is in the 1-3-4-2 order A single timing belt drives the intake and exhaust camshaft Piston pins holding the pistons in place are locked by snap rings The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout. The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron 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 'Outer Shim Type System' allows for the replacement of the shims without the need to remove the camshaft The intake manifold has four independent ports and benefits from inertia build up to improve engine torque at low and medium speeds This prevents oil from being shifted away from the oil pump suction pipe There are four generations of the 3S-GE, which were used in the Toyota Celica, MR2, Toyota Caldina, Toyota Altezza and Lexus IS200 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 The cast iron cylinder block holds four cylinders which are approximately two times the length of the piston stroke The top of the cylinders are covered by the cylinder head The cam journals are lubricated by an oiler port located in the middle of the camshaft. At the bottom of the cylinder block is an oil pan which stores the oil. The Toyota 3S-GE is an in-line 4 cylinder engine manufactured by Toyota and tuned by Yamaha Motor Company Ltd. This is sometimes referred to as a 'non-interference' engine. Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt.
