Fuel delivery system for engine

The utility model provides a fuel delivery system for engine. This fuel delivery system includes case, temperature sensor, conveying line, return line, heat exchanger, first valve, second valve, stores up ware and controller. Controller configuration is the signal of the temperature of the fuel of receive instructions incasement existence. The controller still disposes to controlling at least onein first valve and the second valve based on the signal of receipt at least in part to through return line with accumulate the ware with at least partly fuel optionally bypass to case. This partly fuel is suitable for the temperature of the fuel of improvement incasement existence. The utility model discloses a fuel delivery system provides a scheme simple, effective and with low costs to pressurein the control box, and then control the pressure of carrying supply engine's the vaporization natural gas. Consequently, fuel delivery system has saved the needs to extra pressure boost / force pump, has consequently reduced
