Genuine Honda Fit Fuel Rail

The Honda Fit Fuel Rail supplies pressurized gasoline to the injectors, enabling the compact engine to run smoothly and with low emissions. In the early model years, the system combined a low pressure electric pump with a transverse aluminum Fuel Rail that fed multiport injectors located just in front of each intake valve, a configuration that affords precise control of the pulse width for everyday driving demands. Later incarnations of the Fit subcompact took technology based on the common rail direct injection, with the Fuel Rail being upgraded to withstand much higher pressures in order to atomize the fuel into much smaller droplets to achieve better combustion and power. Regardless of generation, the Fuel Rail links the pump to each injector by way of one manifold, and a regulator maintains pressure for accurate metering of fuel by the powertrain control module at idle or under heavy load. Two main styles therefore appear throughout the life of the car, the standard port injection rail and the high pressure common rail. The major distinction is operating pressure, where the first is based on modest psi appropriate to the intake runner, and the second withstands pressures that can exceed 2,000 bar, to spray straight into the cylinder. Both designs share the same objective, to provide consistent fuel flow, be as efficient as possible, and to keep the agile Honda Fit responsive in day-to-day use, making every Honda Fit owner appreciate a Fuel Rail designed with dependability on the versatile Honda platform.
