Toyota Prius Fuel Rail

The robust structure of the Toyota Prius Fuel Rail facilitates the secure distribution of fuel from the pump to the injectors for a properly functioning engine system. The early generations utilized a port-injection Fuel Rail positioned on the runners of the intake manifold that maintained moderate pressure. The powertrain computer then altered the injector pulse width for either idle or heavy load. Subsequent designs implemented a Fuel Rail similar to the common rail type for gasoline direct injection, where the pressure is increased to thousands of psi so that very fine droplets can enter the combustion chamber directly, increasing efficiency and further reducing emissions. Throttle-body injection once referred to fuel delivery systems that performed both air and fuel injection in the same housing. Due to the popularity of a dedicated Fuel Rail layout, throttle-body injection became rare for modern designs such as the Prius. Separating fuel delivery from airflow enhanced accuracy and responsiveness. The significant difference between Fuel Rail designs of the same Prius generation is the capacity to hold pressure and the position of the injectors. Port systems, for example, feed the valves from outside the cylinder. These enhancements give each Toyota driver the assurance of reliable starts while enabling Toyota to maximize hybrid economy.
