Toyota Car Parts - 3S-GE Engines

Its cylinders are numbered 1-2-3-4 with cylinder number 1 beside the timing belt To adjust the valve clearance, adjust the shims above the valve lifters The cam journal is supported on five points between the valve lifters of each cylinder and on the front of the cylinder head At the bottom of the cylinder block is an oil pan which stores the oil The cam journals are lubricated by an oiler port located in the middle of the camshaft Oil holes are located in the middle of the crankshaft to provide oil to the connecting rods, bearing, pistons and other moving components. The top of the cylinders are covered by the cylinder head 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 The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout. This is sometimes referred to as a 'non-interference' engine. Built into the cylinder block are coolant channels, which cool the block which houses the pistons The 'Outer Shim Type System' allows for the replacement of the shims without the need to remove the camshaft. Piston pins holding the pistons in place are locked by snap rings. Additionally, the 3S-GTE engines were based on the 3S-GE designs This prevents oil from being shifted away from the oil pump suction pipe. The intake manifold has four independent ports and benefits from inertia build up to improve engine torque at low and medium speeds.
