I-530E High Torque Engine Durability 6. Two-Piece Forged Steel Crown Piston In 530E engines rated 300 hp and above, the center combustion bowl design and 8% longer steel piston pin distribute load and thermal stresses evenly for more efficient combustion, improved cold starting and longer life 7. Piston Cooling Jets Lower piston and ring temperatures result in lower thermal stresses and longer life. Targeted oil distribution through high volume jets increases flow up to 43%. 8. Viscous Vibration Damper Heavy-duty damper efficiently controls torsional vibration and extends the life of the 530E HT. The result is smooth performance performance and driveability. 9.
Stainless Steel Injector Sleeves This robust system of injector protection is extended-life coolant compatible. 10. Optimized Cylinder Head Coolant Flow Enhanced design of extended-life coolant-compatible cylinder head directs flow and maximizes cooling for long valve and power cylinder life. 10. Replaceable Valve Seat Inserts Hardened inserts add durability and "second" engine life capability during rebuild. Page No. 56 COPYRIGHT© 2011INTERNATIONAL TRUCK AND ENGINE CORP.
