Hino500 Engine J08C Air Exhaust Valve

1. Inlet valve use Cr40,It has good performance such as wear resistance, chemical corrosion resistance, tensile strength, high elasticity, high pressure load resistance, high wear resistance strength, strong shock absorption, tear resistance, radiation resistance, high load bearing, shock absorption and cushioning. Has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity.

2. Outlet valve use 21-4N, a kind of High-strength steel with high temperature resistance, corrosion resistance, distortion resistance and anti-seepage tensile steel, it can meet the working conditions of the exhaust valve of a heavy-duty gasoline engine and has a long life.

Function of Exhaust Valves
The exhaust valve is a crucial component in an internal combustion engine, responsible for managing the expulsion of burnt gases from the combustion chamber. Its primary functions include:
Gas Release – Opens during the exhaust stroke to allow hot, high-pressure combustion gases to exit the cylinder.
Sealing the Combustion Chamber – Closes tightly during intake, compression, and power strokes to maintain cylinder pressure.
Heat Dissipation – Withstands extreme temperatures (up to 800–900°C in gasoline engines, higher in diesel/turbo engines).
Emission Control – Ensures efficient expulsion of exhaust gases to reduce backpressure and improve engine efficiency.
Materials Used in Exhaust Valves
Exhaust valves endure much harsher conditions than intake valves, requiring materials with superior heat and corrosion resistance. Common materials include:
Heat-Resistant Stainless Steel (e.g., 21-2N, 21-4N, Inconel 751) – High nickel and chromium content for thermal stability.
Inconel (Nickel-Chromium Superalloy) – Used in high-performance and turbocharged engines for extreme heat resistance.
Titanium (in racing/performance engines) – Lightweight but expensive; often coated for wear resistance.
Sodium-Filled Valves – Hollow stems filled with sodium to improve heat transfer (common in high-stress engines).
Stellite or Ceramic Coatings – Applied to valve faces for enhanced wear and corrosion resistance.
Design Features
Reinforced Valve Head – Thicker design to handle thermal stress.
Hardened Valve Seat Contact Area – Prevents erosion from hot exhaust gases.
Stem Surface Treatments (e.g., chrome plating, nitriding) – Reduces friction and wear.
Challenges & Innovations
Thermal Fatigue & Oxidation – Advanced alloys and coatings extend valve life.
Weight Reduction – Titanium and hollow-stem designs improve high-RPM performance.
