Toyota Car Parts - 3S-GE Engines

Built into the cylinder block are coolant channels, which cool the block which houses the pistons To adjust the valve clearance, adjust the shims above the valve lifters 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 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. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components. 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) The cam journals are lubricated by an oiler port located in the middle of the camshaft The cylinder heads are made of aluminium alloy. 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 The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout. The cast iron cylinder block holds four cylinders which are approximately two times the length of the piston stroke This is sometimes referred to as a 'non-interference' engine. There are four generations of the 3S-GE, which were used in the Toyota Celica, MR2, Toyota Caldina, Toyota Altezza and Lexus IS200 The pistons are made from an aluminium alloy, designed to withstand high temperatures. All 3S-GE engines had a displacement of 2 A single timing belt drives the intake and exhaust camshaft. The ignition order of the cylinders is in the 1-3-4-2 order.
