Revotron 1.2T

B.

Electronic Fuel Injection 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 to 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 1.2T engine to be

Bharat Stage lV (BS-lV) 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.
