Which sensor has the greatest influence on injector pukse width besides yhe maf sensor?
Besides the Mass Air Flow (MAF) sensor, the manifold absolute pressure (MAP) sensor has a significant influence on injector pulse width. The MAP sensor measures the pressure within the intake manifold, providing crucial data for the engine control unit (ECU) to adjust fuel delivery based on engine load and operating conditions. Additionally, the engine temperature sensor can also impact pulse width by influencing fuel requirements based on engine temperature.
What sensor has the greatest influence on injector pukse width besides the maf sensor?
Besides the mass air flow (MAF) sensor, the engine coolant temperature (ECT) sensor has a significant influence on injector pulse width. The ECT sensor provides crucial data about the engine's operating temperature, allowing the engine control unit (ECU) to adjust fuel delivery for optimal combustion. Additionally, the throttle position sensor (TPS) also plays a role by indicating how much the throttle is open, affecting the required fuel for acceleration and load conditions. Both sensors help the ECU modulate pulse width for efficient engine performance.
What is the difference between the pulse width and the duty cycle of an injector?
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
What controls injector pulse on a 98 wrangler?
The engine computer (pcm) controls the injector pulse. It looks at numerous sensors and switches to calculate pulse width
What could cause an no start condition if you have good spark at plugs good fuel press and injector pulse width?
possibly a bad crank sensor
What is pulse injector width?
Pulse injector width refers to the duration of the time interval during which a pulse injector delivers fuel or other fluids into an engine's combustion chamber. This timing is critical in optimizing engine performance, fuel efficiency, and emissions. A properly calibrated pulse width ensures that the right amount of fuel is injected at the precise moment for efficient combustion. It is typically measured in milliseconds and can vary based on engine requirements and operating conditions.
What does your map sensor do on my 5.2 liter jeep grand Cherokee do?
The map sensor measures intake manifold vacuum . The signal is varied from high to low, this voltage signal change along with the throttle position sensor,vehicle speed sensor, o2 sensor, the computer uses the signals to vary injector pulse width.
If the injector pulse width is increased the air fuel ratio becomes what?
If the injector pulse width is increased, the air-fuel ratio becomes richer, meaning there is more fuel relative to air in the mixture. This happens because a longer pulse width allows the fuel injectors to deliver more fuel into the combustion chamber. A richer mixture can improve power output but may also lead to increased emissions and reduced fuel efficiency if excessively rich.
should o2 sensor extenders and pulse width modulator be used together with hho generator.?
yes
84 Toyota pickup that had a carburated motor in it you put a 86 22re EFI motor in changed the wiring not getting any injector pulse where does the ECU get power from and why is there no injector pulse?
did u install all components like resister,igniter,etc from the 86? the ground 4 inj.goes 2 the intake.distributor from 86 also needed .4 more info email me. My take is that the MAF sensor enables the fuel pump and the igniter send a signal to prove rpm enabling injection pulse which is then controled by TPS and air flow along with rpm to adjust pulse width, giving the engine more or less fuel on demand.
What provides injector pulse to a 3.0 1993 Ford Taurus?
Each injector has a connector with two wires. One of the wires is supplied with a constant 12 volts when the key is in the "run" position. While the engine is being cranked or running, the other wire is supplied with a pulsed negative ground from the pcm (powertrain control module - computer) to complete the circuit and therefore operate (pulse) the injector. The pcm references the cam sensor so it knows when to initiate the timing sequence for the injectors. In addition, the pcm uses info which it obtains from a number of sensors on the engine to then calculate the varying pulse width needed for correct engine operation under various driving conditions. Hope this helps! Walt
How do you calculate the width of pulse in pulse position modulation?
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
