Complete Cylinder Head V2403 V2403-M Turbo Engine With Valve

V2403 cylinder head matches V2403 series diesel engines, commonly used for overhaul of mini excavators, forklifts, farm equipment and small generator sets. It has five core features:

1. Optimized spiral intake port. The port is designed with flow simulation to generate gentle and steady intake swirl for direct injection combustion. It improves fuel-air mixing within the limited space of small-displacement engines, delivering reliable cold start and smooth idling performance.
2. Double-layer thermal buffer structure for exhaust seats. A heat isolation gap is reserved around exhaust valve inserts to absorb sudden thermal shock from hot exhaust gas. It slows heat transfer to the main casting and greatly reduces thermal cracking around seats during long idle operation.
3. Compact surrounding micro water galleries. Narrow cooling passages wrap closely around combustion chambers and valve seats. It achieves fast heat exchange while keeping the cylinder head compact and lightweight, matching the limited cooling space of small machinery and preventing hot spots.
4. Built-in integrated oil diversion channels. Internal cast oil passages lead lubricant directly to rocker positions with smooth, short routes. Fast oil supply prevents dry friction of rocker assemblies and reduces abnormal noise and premature wear of the valve train.
5. Comprehensive multi-item inspection for finished products. Every unit goes through dye penetrant crack test, hydrostatic leak test, deck flatness check and valve seat concentricity verification. Position tolerance of all mounting holes is verified to screen casting and machining errors and cut workshop rework.

This lightweight cylinder head is widely stocked for small equipment repair. It is available as bare casting or pre-assembled valve version. When fitted with overhaul gaskets, it maintains stable sealing and low failure rate under intermittent working cycles.
