Fill Cycle. During pre-injection all internal components are found in their spring loaded (non-actuated) positions. The solenoid is not energized and the poppet valve is blocking high pressure oil from entering the injector. The plunger and intensifier are at the top ...
WebJul 4, 2024 · A fuel injector can achieve high pressure up to 500 bar by using spring loaded valve. High pressure fuel from the fuel pump then acts on the underside of the fuel injector body. This pressure when reach a certain point, it lift the needle valve against the spring tension; injecting atomized fuel oil through nozzle. WebA TBI system delivers fuel from a nozzle into air above the throttle plate at atmospheric pressure. MASS air flow uses 5 sensors: MAF, IAT, O2, TPS, ECT. Speed density method: Does not require a air quality sensor, but rather calculates the amount of fuel required by the engine. Throttle-body injection.
