MarComp Combustion Chamber Tester
Tester measuring the combustion chamber pressure drop at TDC of 4-stroke diesel and gas engines to assess valve and piston ring condition.
Description
MarComp monitors the condition of valves and piston rings of 4-stroke diesel and gas engines. It connects to the cylinder's indicator cock (W1-1/6" standard thread) and to supply air at 6 to 9 bar; with the supplied stop clock the operator measures the pressure drop over time in the combustion chamber with the piston at TDC. This reveals worn valves and valve seats as well as worn or broken piston rings.
