Abstract
A fuel delivery system provided with at least a fuel delivery pump and a high pressure pump distributing fuel to individual injectors on the cylinders included with apparatus for preheating the intake air for air-compressing internal combustion engines. Communication therewith occurs through a header pipe. Components thereof include an injection valve provided at the end of all high pressure pipes leading to the engine cylinders and arranged to open at a predetermined pressure. Each of the high pressure pipes is provided with a branch off conduit arranged to be shut off by an isolating valve. All branch offs are brought together to a common header pipe supplying the preheating equipment with fuel.
