It includes two ductile-iron caliper halves pressurized by a single inlet-port crossover tube
, allowing hydraulic pressure to actuate the 2.25-inch-diameter piston in each half.
Where earlier materials were limited to components away from the engine systems, Ryton PPS can be used in emissions such as EGR systems and vent tubes, cooling applications that include thermostat housings, crossover tubes
, end tanks, electrical systems that have connectors and engine sensors, and fuel components such as fuel rails, fuel pump impellers and fuel pressure sensors.
If the temperature spreads are larger than 100[degrees]F, it may indicate problems--such as clogged fuel nozzles, failure of crossover tubes
, or cracks in the turbine liner--that could cause turbine breakdown.
