MAN CNG BusesSafety aspects

What makes the CNG bus so safe ?

European regulation ECE-R110, StVZO, German pressure cylinder regulation, safety and accident prevention regulations are fulfilled

Individual inspection of every vehicle prior to start of operation (by officially certified inspector)

Filing nozzle with integrated check valve and shut-off valve

Fuel lines and unions made of stainless steel, gas tight

Liners Aerospace proven materials Operating pressure 200 bar, test pressure 300 bar, rated pressure 500 bar – Safety factor 2,5 ! Cylinder lifetime 20 years without need for intermediate inspection

Solenoid valves shut off fuel supply when ignition is switched off

Cylinder valves equipped with mit Flow limiter PRD (pressure relieve device): melting fuse will prevent cylinders from overpressure (in case of

fire)

Overview: environmental performance of buses


Advantages of CNG technologyFocus: Biogas / Hybrid





Advantages of CNG technologyFocus: CNG/Biogas

The cleanest, CO2 neutral, reliable, non-fossil and affordable solution for public transport:

• Buses readily available• Proven reliable technology• Highest well to wheel efficiency on CO2 reduction• Lowest PM emission• Lowest NOx emission• Low noise production• No link with food chain discussion


Advantages of CNG technologyFocus: CNG/Biogas

The cleanest, CO2 neutral, reliable, non-fossil and affordable solution for public transport:

• Exceeds Euro 6• No Adblue• No Battery Packs, disposal of, replacement• Biogas compatability• No Spillage risks• Future Proof - Biogas• Manure, Municipal Waste, Food waste – Not crop reliant• Biogas can be fed directly into the Gas Main
