KTA19 M3 Features
Corrosion-Resistant High-Strength Engine Block
Made from high-nickel-chromium cast iron (3.2% Ni, 1.8% Cr) with compacted graphite casting, the block offers 40% improved resistance to seawater corrosion. The wet-type cylinder liners feature 0.05 mm chrome-plated walls and double fluororubber seals, preventing coolant or seawater leakage.
01
Advanced Cylinder Head & Valve System
Each cylinder head is independent and reinforced with 0.2% vanadium alloy, improving thermal deformation resistance by 30%. The four-valve-per-cylinder design (Si-Cr steel intake, Ni-Cr steel exhaust) and nitrided valve guides ensure extended durability under continuous high-load operation.
