Fuel injection pump video PART-2 link:-https://youtu.be/J-fifHWfbP0 Facebook page link:-https://www.facebook.com/SaouravKumar... tata indigo injection pump setting to get maximum mileage and lowest smoke and high pickup and it helps to tune up the engine and its sound. also helps to reduce black smoke from exhaust and helps to increase engine life. mainly rpm is very difficult to set after 50000km manually but my video will help you. some extra knowledge:- Primary Functions:--- 1. Fuel pump injection timing control. 2. Glow plug pre & post heat control. 3. EGR system on-off control. Secondary Functions:--- 1. FICD (Fast Idle Control Device Control). This is the device which increases the rpm when the AC is switched on. 2. AC switch off at high Engine temperature and high loading. 3. High altitude proportional control. 4. Fault detection & storage of trouble codes. The ECU gets its inputs/information about Throttle position, coolant temperature, ambient temperature, engine rpm, crankshaft angle & Injection start from the following sensors on the engine : 1. Throttle Position Sensor or Fuel Level Sensor : This is a potentiometer connected to the fuel delivery lever which is actuated when the accelerator pedal is pressed. It sends a DC voltage to the ECU which is proportional to the accelerator position. 2. Temperature Sensor: This is a thermistor type of sensor, monitoring the coolant temp. 3. RPM sensor: Part of the alternator. Gives 3 voltage pulses for one revolution of the crankshaft. 4. Crankshaft Angle Sensor or Crankshaft Position Sensor. This is mounted on the flywheel housing and provides piston TDC (Top Dead Centre) information to the ECU, in the form of a number of voltage pulses per 90 degrees angle of rotation. 5. Needle Lift Sensor: This sensor is part of No. 4 cylinder fuel injector, & sends a voltage signal to the ECU at the precise beginning of injection. How it works : Based on the inputs from these sensors, the ECU controls the following units through Relays, Solenoid switches & PWM control : 1. Glow Plug Heaters: These are for pre-heating the cylinders. The ECU controls the glow plugs ON time based on ambient & engine temperature. 2. Fuel Pump: Injection timing is controlled depending on the position of the accelerator pedal----timing is advanced automatically at higher rpm. The ECU controls a cam actuator inside the fuel pump, based on a look-up table stored in the ECU program ROM. 3. EGR: This is the Exhaust Gas Recirculation system. Part of the exhaust gases is mixed with the air intake to reduce temperatures inside the cylinders to below 210 deg C., which sharply reduces the formation of Nitrogen Oxides (Nox) in the exhaust, thereby reducing harmful pollutants as reqd. by Euro / BS 2 & 3 norms.The EGR valve is controlled by the ECU, & gets activated in the rpm band 1100 to 3000 rpm, with small variations to compensate for engine temp & loading. 4. FICD: The fast idle control is used to increase the idle rpm when the AC is switched on. The ECU activates the FICD through a solenoid switch by monitoring the AC compressor clutch voltage. The ECU also continuously monitors the engine temperature, & switches off the AC if upper limits are exceeded. All the sensors are also monitored continuously, and a fault or trouble code is stored in non-volatile memory in case of a fault, & the Check Engine Light comes ON. IF THIS VIDEO HELPS YOU DON'T FORGET TO LIKE & SHARE THE VIDEO & ALSO SUBSCRIBE TO MY CHANNEL I film, edit and publish each video on my own. I have had many viewers comment and let me know how I have taught them how to fix their car themselves and save them $$$$ and I love it! thank you.
