    摘要： In an engine 70 including an EGR apparatus 91 which refluxes a portion of exhaust gas from an exhaust manifold 71 to an intake manifold 73 as EGR gas, it is an object of the present invention of the application to improve assembling operability of a differential pressure sensor 163 which detects a differential pressure between intake pressure of the intake manifold 73 and exhaust pressure in the exhaust manifold 71. According to the engine 70 of the invention of the application, the differential pressure sensor 163 is mounted on a head cover 160 which covers an upper portion of a cylinder head 72. An intake pressure taking-out passage 166 which is in communication with the intake manifold 73 is formed in the cylinder head 72. An intake pressure introducing passage 169 which is connected to the differential pressure sensor 163 is formed in the head cover 160. The intake pressure taking-out passage 166 and the intake pressure introducing passage 169 are in communication with each other. According to this configuration, a stay which is for exclusive use for mounting the differential pressure sensor 163 and an external pipe for taking intake pressure into the differential pressure detecting means 163 become unnecessary.

    摘要： The present invention relates to a method for supplying fuel for a motor of a vehicle by a fuel supply system comprising: a first tank for containing a first fuel; supply means for supplying fuel to the motor; a supply line, for allowing said first fuel to pass from said first tank to said supply means; a return line, for allowing fuel to pass from said supply means to said first tank; a recirculating line, connected with said supply line and said return line, for allowing fuel to pass from said return line to said supply line; and valve means, configured to selectively direct fuel from said return line to said supply line by said recirculating line, or to said first tank; wherein said method comprises the steps of controlling the speed vehicle; controlling the vehicle motor load; defining a first threshold value of the vehicle speed; defining a second threshold value for the vehicle motor load; letting said first fuel passing from said first tank to said supply means through said supply line, and from said supply means to said first tank through said return line, preventing passage of fuel along said recirculating line, when the vehicle speed is lower than said first threshold value and/or motor load is lower than said second threshold value; or making said first fuel passing from said first tank to said supply means through said supply line and then through a closed circuit comprising a part of said return line, said recirculating line and a portion of said supply line, permitting passage of said first fuel through said recirculating line, so that said first fuel arrives again within said supply means, when the vehicle speed is higher than said first threshold value and motor load is higher than said second threshold value, so as to prevent an excessive increase within said first tank caused by inlet within the first tank of the first fuel warm arriving from said supply means.

    摘要： The common rail fuel injection system for a piston engine (1) comprises a fuel rail (9), at least one fuel injector (3) connected to the fuel rail (9), a first fluid receiver (6), a second fluid receiver (7), at least one low-pressure pump (5) for supplying fuel into the first fluid receiver (6), at least one high-pressure pump (10) for receiving fuel from the second fluid receiver (7) and for supplying the fuel into the fuel rail (9), and at least two flow control valves (8a, 8b, 8c) connected in parallel. Each of the flow control valves (8a, 8b, 8c) is individually controllable and connected to the first fluid receiver (6) on the upstream side and to the second fluid receiver (7) on the downstream side.

    摘要： A fuel system (4) for a combustion engine (2) comprises a first fuel tank (20), a second fuel tank (22), a first fuel pipe (36) arranged in connection with the first fuel tank (20) and the second fuel tank (22), a second fuel pipe (40) arranged in connection with the first fuel tank (20), a main feed pump (26), and a transfer pump (28). The main feed pump (26) feeds fuel from the first fuel tank (20) through the second fuel pipe (40), and the transfer pump (28) feeds fuel from the second fuel tank (22) to the first fuel tank (20) via the first fuel pipe (36). A valve (32) is arranged downstream of the transfer pump (28). The valve (32) comprises an inlet connected with the transfer pump (28), a first outlet connected with the first fuel pipe (36) and a second outlet connected with the second fuel pipe (40). The fuel system reduces the risk of insufficient or loss of fuel supply to the combustion engine in the event of an operational disruption, and enables a method for continued operation, albeit with potentially reduced power. This also secures the operation of the combustion engine (2) and a vehicle equipped with such a fuel system.
