Abstract
A vehicle fuel rail system for fuel delivery and liquid fuel retainment therein. The vehicle fuel rail system comprises a fuel rail and a chassis connector in fluid communication with the fuel rail. The fuel rail has a first bank and a second bank connected to the first bank by way of a crossover line. The first bank has a first top portion and a first bottom portion and the second bank has a second top portion and a second bottom portion. The crossover line has a first end disposed at the first bottom portion and a second end disposed at the second top portion. The chassis connector has a tank end and an rail end wherein the tank end is connected to the vehicle fuel tank and the rail end is disposed at the first top portion.
Claims22
A vehicle fuel rail system for fuel delivery from a fuel tank to fuel injector cups of a vehicle engine and for improved liquid fuel retainment in the system, the system comprising:
- a fuel rail having a first bank and a second bank in fluid communication with the first bank by way of a crossover line, the first bank having a first top portion and a first bottom portion adjacent and in fluid communication with the fuel injector cups, the second bank having a second top portion and a second bottom portion adjacent and in fluid communication with the fuel injector cups, the crossover line having a first end disposed at the first bottom portion and a second end, the second end being in fluid communication with the first end and disposed at the second top portion for fuel inlet to the second bank;
- and
- a chassis connector having a tank end and an rail end in fluid communication with the tank end, the tank end being connected to the fuel tank and the rail end being disposed at the first top portion of the first bank for fuel inlet to the first bank.
A vehicle fuel rail system for fuel delivery from a fuel tank to fuel injector cups of a vehicle engine and for improved liquid fuel retainment in the system, the system comprising:
- a fuel rail having a first bank and a second bank in fluid communication with the first bank by way of a crossover line, the first bank having a first top portion and a first bottom portion being adjacent and in fluid communication with the fuel injector cups, the second bank having a second top portion and a second bottom portion adjacent and in fluid communication with the fuel injector cups, the crossover line having a first end disposed at the first bottom portion and a second end the second end being in fluid communication with the first end and disposed at the second top portion for fuel inlet to the second bank, the first bank including a first inlet aperture for fuel delivery to the first bank and an outlet aperture through which the first end is disposed, the second bank including a second inlet aperture through which the second end is disposed;
- and
- a chassis connector having a tank end and an rail end in fluid communication with the tank end, the tank end being connected to the fuel tank and the rail end being disposed through the first inlet aperture at the first top portion of the first bank for fuel inlet to the first bank.
A vehicle fuel rail system for fuel delivery from a fuel tank to fuel injector cups of a vehicle engine and for improved liquid fuel retainment in the system, the system comprising:
- a fuel rail having a first bank and a second bank in fluid communication with the first bank by way of a crossover line, the first bank having a first top portion and a first bottom portion being adjacent and in fluid communication with the fuel injector cups, the second bank having a second top portion and a second bottom portion adjacent and in fluid communication with the fuel injector cups, the crossover line having a first end disposed at the first bottom portion and a second end, the second end being in fluid communication with the first end and disposed at the second top portion for fuel inlet to the second bank, the first bank including a first inlet aperture for fuel delivery to the first bank and an outlet aperture through which the first end is disposed, the second bank including a second inlet aperture through which the second end is disposed;
- and
- a chassis connector having a tank end and an rail end in fluid communication with the tank end, the tank end being connected to the fuel tank and the rail end being disposed through the first inlet aperture at the first top portion of the first bank for fuel inlet to the first bank,
- wherein the first inlet aperture is formed at the first top portion of the first bank, the inlet chassis line being disposed through the first inlet aperture and extending therefrom so that the rail end is disposed at the first top portion for fuel delivery to the first bank,
- wherein the outlet aperture is formed at the first bottom portion of the first bank, the crossover line being disposed through the outlet aperture ard extending therethrough so that the first end is disposed at the first bottom portion,
- wherein the second inlet aperture is formed at the second top portion of the second bank, the crossover line being disposed through the second inlet aperture and extending therethrough so that the second end is disposed at the second top portion.
