- Dense power concentration
- More accurate governing of the air-fuel-mixture at atmospheric pressure
- Homogenisation of the air-fuel-mixture by the compressor of the TC
- Enhanced efficiency
- No pre-pressurising of gas necessary
- No danger of backfiring due to low combustion speed by extremely lean mixture formation
- Flexible use for different types of gases |
|
 |
- Optimum efficiency
- Homogenisation of the air-fuel- mixture by TC and intercooler
- No pre-pressurising of the gas required
- Reliable compliance to NOx, CO and HC emission limits |
|
- No pressure loss during mixture formation. Enhanced power output at max. efficiency.
- Also with changing mass flow of the gas, the air-gas ratio remains to be constant.
- Using the combustion temperature, e.g. the emission control of the engine is governed through TEM by adjusting the air-gas ratio. |
 |
- Direct physical dependency of control variable and set value
- Only slight variations of TBr per working cycle
- Different loads or charging pressures have hardly any influence on TBr
- Influences out of gas type on TBr are of order two only, so negligible
- Same TBr mean same emission levels
|
- All control, measuring variables are collected and processed centrally
-
Also plant control circuits can be regarded, e.g. compressor control, heat demand, etc. |
- Remote operation and remote diagnosis allow plant operation via modem-
- including handling of warning and fault messages |
