Abstract:
1. A supercharged diesel engine having a Common-Rail injection system which utilizes at least one high pressure fuel reservoir that is connected with a high pressure fuel pump via a high pressure fuel line, said supercharged diesel engine comprising: at least one bank of cylinders having the cylinders thereof disposed in a row, wherein at least one cylinder head is associated with said bank of cylinders, wherein at least one of said cylinders is associated with said at least one cylinder head, which is provided with air inlet openings, and wherein a plurality of said cylinders are associated with said high pressure fuel reservoir, which is connected via fuel injection lines to respective fuel connections, disposed on said at least one cylinder head, of individual ones of said cylinders; and at least one charged air conduit for distribution of charged air and having a first chamber for conveying the charged air, wherein said air inlet openings of said at least one cylinder head are connected to said first chamber in a gastight manner, wherein said charged air conduit has at least one second chamber, which is separate from said first chamber and has a removable lid, wherein the mounting means are provided in said at least one second chamber, wherein said high pressure fuel reservoir is adapted to be secured in said at least one second chamber via said mounting means, wherein said at least one second chamber is provided with a first passage via which said high pressure fuel line and said high pressure fuel reservoir are adapted to communicate with one another, wherein said at least one second chamber is provided with at least one second passage, facing said at least one cylinder head, via which said fuel injection lines and said fuel connections of said at least one cylinder head are adapted to communicate with one another, and wherein said at least one second chamber, when said lid is in place, at least partially encloses said high pressure fuel reservoir, said fuel injection lines and said fuel connections such that in the event of leakage at any of said high pressure fuel reservoir, said fuel injection lines, and said fuel connections, leaking fuel is adapted to flow into said at least one second chamber, wherein said at least one charged air conduit is secured to said at least one cylinder head, and wherein said at least one second chamber is provided with an opening for a discharge of fuel that during leakage enters said second chamber, wherein said at least one second passage is sealed relative to a space surrounding said at least one charged air conduit, and wherein a sealing surface of said at least one second passage is formed by portions of said at least one cylinder head.
