Toyota Car Parts - 3S-GE Engines

The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout Piston pins holding the pistons in place are locked by snap rings Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt. The cam journals are lubricated by an oiler port located in the middle of the camshaft 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) This is sometimes referred to as a 'non-interference' engine The top of the cylinders are covered by the cylinder head 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. Additionally, the 3S-GTE engines were based on the 3S-GE designs The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head. The Toyota 3S-GE is an in-line 4 cylinder engine manufactured by Toyota and tuned by Yamaha Motor Company Ltd. The crankshaft, located within the crankcase, rotates on five aluminium alloy bearings and is balanced by eight weights. Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components. 0 L The ignition order of the cylinders is in the 1-3-4-2 order. The cast iron cylinder block holds four cylinders which are approximately two times the length of the piston stroke. Built into the cylinder block are coolant channels, which cool the block which houses the pistons. The first compression ring and the oil ring are made of steel, the second compression ring is made of cast iron. All 3S-GE engines had a displacement of 2. To adjust the valve clearance, adjust the shims above the valve lifters.
