Abstract: Disclosed herein are a device and method designed for determining the liquid level in a container through measuring the pressure in the liquid by a pressure sensor located at the bottom of the container within a chamber designed to prevent solid particles dispersed in the liquid from reaching the sensor. Measuring the pressure of the liquid in the container can be based on an upper chamber located above a lower chamber, both adjacent chambers are located within a container. The upper chamber comprises tiny slots allowing the liquid in the container to enter the upper chamber and exert a weight on a diaphragm gasket functioning as a common-wall of the two adjacent chambers. The diaphragm gasket exerts pressure resulting from the liquid weight, on the lower chamber containing the pressure sensor designed to measure the pressure exerted on the lower chamber.

A leak diagnosis includes a first-stage diagnosis to determine whether or not falling of a pressure in a crank case after closing of the shutoff valve under a non-supercharging condition is normal.

When the sensed intake air quantity is equal to the actual intake air quantity, presence of an in-system leak is determined, and when the actual intake air quantity is larger, presence of an out-of-system leak is determined.

Abstract: A method is provided for determining whether post-weld heat treatments should be required for external attachment welds in applications where stress corrosion cracking is a possibility. According to the method, residual stress values are measured in test samples welded at high input heat levels and test samples welded at low input heat levels for a variety of different wall thickness. A threshold residual stress level is determined according to a method of selecting a common pipe used in industry and measuring the residual stress level in the longitudinal seam of the pipe. The measured residual stress values for the high and low heat input welds are compared against the threshold to determine whether for a particular wall thickness, the high and low input data exceeds the threshold, indicating whether post-weld heat treatments are required.
