<p>The present invention relates to a high- pressure system in combustion engines and particularly to leak alarms. The idea is to connect the leak flow space of the high-pressure pipe via a valve to an expansion space and furthermore, to measure the pressure in the leak flow space. The valve provides the operatively necessary limitation of the volume of the flow space for pressure measurement and at the same time it acts as a discharge passage for possible over- pressure and leak fuel. A direct passage out of the engine may act as an expansion space. Another option is to use the channel for continuous leak connected to the fuel recycle system as an expansion space.</p> |
