How is low pressure corrected using DFT #1500 “Hammerdown”?
Low compression pressure indicates a mechanical problem, One cause can be failure of the compression rings on the piston to float freely and conform to the slight irregularities of the cylinder wall (Other causes are broken rings, stuck valves, burned pistons or valves, scored cylinders, and cracked heads.) Rings fail to float freely when carbon builds up behind and around them. DFT #1500 “Hammerdown” removes and prevents such build up so that design compression pressures can be achieved. Low combustion pressure also may indicate mechanical problems. However, poorly burning fuels and/or fuels with low heating values can give low combustion pressures. By helping fuels to burn completely, DFT #1500 “Hammerdown” helps to minimize low combustion pressures from such fuels.
