1.	Which among the following tunes the fuel delivery to achieve the correct fuel ratio?(a) Float valve(b) Ecu(c) Oxygen sensor(d) Temperature sensorThis question was posed to me during an interview for a job.The query is from Petrol Injection in division Petrol Engine Fuel Supply System of Automotive Engine Design
Answer» Right ANSWER is (B) Ecu Best explanation: The ECU uses the information from the sensors to fine-tune the fuel delivery to achieve the just correct fuel ratio. The sensors monitor the mass of air entering the ENGINE and also the amount of OXYGEN in the exhaust.
