Влияние величины межэлектродного зазора свечи зажигания на показатели газового двигателя

Using the ignition system with stored energy in the magnetic field of the ignition coil can not zoom spark plug gap of more than 0,5 mm due to mismatch of the spark discharge conditions in the combustion chamber gas engine that makes us look for opportunities to improve fuel efficiency and environmental performance by optimizing performance spark gap and increase the electrode spark plugs. One way of solving this problem is the use of capacitor ignition systems, which feature is the high rate of rise of the secondary voltage developed by the large value of the secondary voltage, which allows an increased electrode gap spark plugs. Application of the ignition system of capacitor allowed to increase to 1,0 mm electrode gap of the spark plugs of the gas engine, thus reducing emissions of CH and CO, respectively, 33% and 10 %, the fuel consumption is decreased by 5,8 %. Increased clearance gives significantly greater effect on speeding up the process of ignition and combustion mode XX and partial loads than with 80-100 % load engine.
