🚀 Bosch Large-Engine Gas Admission Valve – LE-GV 400
Precision Gas Control for High-Power Engines
The LE-GV 400 gas admission valve is designed for single and dual-fuel large engines, delivering industry-leading precision in metering gaseous fuels like LNG, biomethane, hydrogen, and more.
🔧 Key Features
- Geometric cross-section: 400 mm² — supports a capacity of up to 500 kW per cylinder, ideal for heavy-duty marine, power generation, and industrial application.
- Extreme durability — built to endure up to 720 million switching cycles, with operation across a broad temperature range (−40°C to +110°C).
- Marine-certified — engineered to meet strict classification society standards.
🎯 Performance Benefits
- High-precision gas metering — with ECU integration, each valve individually controls gas intake per cylinder cycle, optimizing combustion efficiency.
- Superior mixture homogeneity — uniform air/fuel mixture ensures complete combustion, reducing emissions and increasing power output.
- Reliable long-term operation — Guaranteed performance over thousands of hours and switching cycles, minimizing downtime and maintenance costs.
⚙️ Applications
- Large single-fuel engines — using gas as the primary fuel.
- Dual-fuel systems — seamlessly switching between diesel and gas modes.
- Marine propulsion systems, power gen sets, heavy-duty trucks, industrial machinery — wherever high-output gas engines are deployed.
