B. Electronic Control :
The engine management software in the vehicle's Engine Control Unit (ECU) controls the fuel injection
and ignition system using a variety of sensors that provides the engine operating conditions and
operates input information.
The ECU includes self-diagnosis to help pinpoint any system malfunctions. Refer to the "Engine
Management System" portion of this section for additional information.
The MPFI type of fuel injection offers many advantages over a single point fuel injection system or a
carburetor engine. The following paragraphs describe the advantages of the electronic fuel injected
engine.
Improved Engine Performance :
The ECU precisely and instantly controls optimum fuel delivery and spark timing according to the
operating conditions, inputs from the engine sensors, and operator input. This control improves vehicle
response and acceleration.
Increased Fuel Economy :
The electronic fuel injection system allows the REVOTRON 110 engine to be Bharat Stage VI (BS-VI)
compliant.
By electronically controlling the air/fuel ratio of the combustion process, the engine maintains an air/fuel
closer to stoichiometric (14.7:1, air to fuel), the optimum ratio for complete combustion of the fuel
mixture.
Decreased Exhaust Emissions :
The use of electronic fuel injection also decreases exhaust emissions because the air/fuel ratio is
precisely controlled through the ECU for operating conditions and driver input. The catalytic convertor
also helps reduce exhaust emissions and specially manufactured to the fuel injection system's operation.
Improved Cold Starting and Operation :
By detecting the atmospheric and engine conditions in which the operator is starting and driving the
vehicle, the ECU can adjust fuel mixture and ignition timing to help the vehicle start more easily when
cold and to warm up faster.
The MPFI ECU achieves all of these advantages by instantly compensating for changes in operating
conditions and sensors inputs. This compensation is faster and more efficient than a mechanical system
or human input.
