Good monitoring of gas and diesel engines in power stations and large ships is crucial for ensuring reliable, economic operation and maximizing service intervals. This task calls for monitoring systems with cylinder pressure sensors that can be permanently installed on the engine and that are capable of operating continuously with absolute reliability. The Kistler company, which has specialized for over 40 years in cylinder pressure measurement, has just completed an extensive series of field tests on a new pressure measuring solution, with highly promising results. The solution proposed by the company is a ring-shaped sensor that simply mounts around a specially made hollow bolt, onto which the indicator or safety valve is reattached after having tightened the sensor. The new C-Sensor device, so called because of its shape, is the key component of the AutoBalancer 5000 system made by the Woodward Governor Company, of Fort Collins, Colorado, USA. Developed primarily to be retrofit on large-bore gas engines used in gas compression and other applications, Woodward`s new engine control system equipped with C-Sensors makes possible substantial reductions in misfiring, detonation, and NO{sub x} emission. The fully automatic closed-loop cylinder balancing system regulates the gas feed to each cylinder as a function of the cylinder pressure measured by the C-Sensor.
