5 mm bores and a 79. 0 mm stroke for a capacity of 2457 cc. The EJ255 engine had a semi-closed deck design whereby the cylinder walls were attached to the black at the twelve, three, six and nine o’clock positions. Compared to its EJ207 predecessor, the EJ255 cylinder block had a new high strength, cast steel alloy rear main journal to reduce bearing oil clearance during cold operation and, as a result, reduce vibration and bearing rumble noise during the warm-up phase. Furthermore, this reduced bearing oil clearance was maintained when the engine was at operating temperature.
Each corner formed by a journal or pin and a web underwent a fillet-rolling process to increase its strength. The connecting rods for the EJ255 engine were made from forged high carbon steel, while big end cap dowel pins and set screws were used for accurate mating. The piston head and ring grooves were coated with Alumite, while the piston skirts had a molybdenum coating to reduce friction. Each piston in the EJ255 engine had three rings: two compression rings and one oil control ring.
Of these, the top piston ring has inner bevels and the second piston ring has a cut on the bottom outside to reduce oil consumption. The EJ255 engine had a low pressure cast aluminium cylinder head that was mounted on a head gasket which consisted of three stainless steel sheet layers. Each camshaft was supported at three journals, held in position by three camshaft caps and had a flange which fitted the corresponding groove in the cylinder head to receive thrust forces. Relative to the EJ207 engine, it is understood that camshaft mass for the EJ255 engine was reduced by 1700 grams through the use of hollow shafts and sintered cam lobes. The EJ255 engine had parallel flow cooling system whereby coolant flowed into the block under pressure, crossed the gasket to the cylinder head and then passed through holes adjacent to each cylinder. The intake valves had hollow stems to reduce mass and inertia, while the exhaust valve stems were filled with sodium. Improved fuel consumption at medium engine speeds and low loads: intake valve timing was advanced to reduce intake air blow back and improve fuel consumption.
Maximum power at high engine speed and load: intake valve timing was further advanced to maximise overlap and utilise the scavenging effect produced by exhaust gas pulsations to draw intake air into the cylinder. Since the intake valve was closed at the end of the intake stroke, air intake efficiency was improved and power increased. The intercooler for the SG Forester XT had a core capacity of 3. 2 litres and cooling capacity of 11. Mitsubishi TD04L turbocharger It is understood that the Subaru SH Forester XT continued to use Mitsubishi TD04L turbocharger, though the shape of the turbine wheel and impeller were changed to improve torque at low-to-medium engine speeds. The Subaru SH Forester XT also introduced a larger intercooler with a core capacity of 3.
8 litres and cooling capacity of 12. GG Impreza WRX had a Mitsubishi TD04L turbocharger which provided peak boost pressure of 0. GG Impreza WRX had a cooling capacity of 11. The catalytic converter was positioned immediately after the turbocharger so that it reached operating temperature sooner, thereby reducing cold-start emissions. The EJ255 engine had multi-point fuel injection with an injection and firing order of 1-3-2-4.
The EJ255 engine had an ignition coil for each cylinder that was positioned directly above the spark plug. While the SG Forester XT had Iridium spark plugs, it is understood that all other models in the table above had platinum-tipped spark plugs. The EJ255 engine had an ignition knock control facility with fuzzy logic that enabled the maximum ignition advance to be used without detonation by constantly adapting to changes in environmental conditions and fuel quality.
