The Gas Engine 18V51/60G 18V51/60G Gas Power Plant Exemplary
The Gas Engine 18V51/60G Spark Ignited (SI) Gas Engines Pre-chamber Spark Ignition Principle Ignition Process: Main combustion chamber will be filled with lean mixture of natural gas and air Prechamber will be flushed with natural gas (rich mixture within prechamber) Compression by upward piston motion (checkvalve prevents gas losses) Spark plug initiates the ignition within prechamber Flames coming out of the prechamber start combustion within main combustion chamber
Spark ignition components derived from 32/40G and 35/44G 18V51/60G Main Changes reliability ~95% standard engine and safety parts from 48/60B + 51/60DF maturity Spark ignition components derived from 32/40G and 35/44G new Piston crown and cylinder liner with reduced fire land height for more efficiency
Gas and Dual Fuel Engines Released fuel gas specification
The Gas Engine 18V51/60G Benefits of the Engine - Summary Based on proven design of V48/60B Highest power densities in his class Increased efficiency with spark ignition Low NOx emissions from gas Low gas-admission pressures High and stable ratings in hot and high power- plant locations Excellent load imposition and load following characteristics Cost savings through favorable price of natural gas Injection: State of the art spark ignition technology
