Abstract:- In the era of growing technology, growth of companies depends upon how efficient their products work in the market with an increase in competition, we are going to discuss on how a modern-day automatic direct fuel injection works as well as engine maintenance system to avoid corrosion in internal parts of an engine, EMS is one of the main components of modern-day I.C engine, how the magnitude of fuel taken according to the power of engine for getting more efficiency, the role of sensors

in the whole process, mixing of fuel with additives in fuel injector (cranked) the flow mass calculation of fuel and by that calculating the efficiency of the engine by automatic direct fuel injection and further on making some assumptions about the after process, and some comments on the usage of the maximum amount of energy generated in a different form are added, and discussion on effect on properties of fuel on adding of additives and selection of additives is also included.

Keywords:- EMS, Direct Fuel Injection, I.C. engine, CVT.

I. INTRODUCTION:

In the era of Electric Transmission System with higher efficiency, we all are still interested in increasing efficiency of I.C Engines too, but with an increase in efficiency, we also have some unwanted results pollution in the environment, corrosion (rusting) of the cylinder inside I.C engine and error in the system such as incomplete combustion and Overheating, etc.

We are going to analyze about control system of blending of petrol with a corrosion inhibitor in cranked and direct electronic fuel injection system as for the reason to increase efficiency the of an engine with least wastage of energy and with less air pollution.

Corrosion in petrol/diesel engine is affected by the quality of fuel used, Sulphuric acid is formed due to Sulphur component present in fuels such as Petrol/Diesel when mixes with air in the cylinder the walls of the cylinder due to high temperature and pressure reacts and forms acid and results in the degradation of material used in a cylinder, Sometimes corrosion in the material is due to a low quality of material used in engine components, sometimes creep effect plays its role in degrading the material which results in corrosion of engine parts.

Exhaust Valves in an engine are subjected to different air medium and gas which sometimes reacts with valves in presence of high temperature and if liners are not fitted well which may also result in incomplete combustion of fuel and

continuous failure in the system and the lifetime of engine decreases.

Lead is also one of the factors which get accumulated in the cylinder of the engine and may affect the efficiency of the engine as well as degrade the material, which on time being decreases engine's lifetime.

So to come up with this problem Scientists used corrosion inhibitors the process went through many iterations and failures, And nowadays at some parts in vehicle engine are having valves of corrosion inhibitors so that failures due to corrosion in the engine gets nullified, And in small-sized engines, corrosion inhibitors are used along with petrol(gasoline). In areas whit, cold weather Antifreeze is also used as a Corrosion inhibitor as at low-temperature water present inside engine cylinder freezes to ice so to overcome this problem antifreeze is used so that the freezing temperature of water molecules resulting combustion of fuel easily, Without any error or failure of the system.

As for automatic control system for direct fuel injection, valve control system and system maintenance are all interconnected with each other in the latest generation petrol/diesel engines. And for setting up and calibration of these systems we need to apply some basic principles of thermodynamics, fluid mechanics, material science and design of the engine compatible with all of this system and properties taken into consideration.

II. THE BASIC WORKING OF THE CONTROL

SYSTEM:

As we know the transmission system of vehicles are different according to their use and on public demand such as CVT (continuous vehicle transmission), auto gear system and manual gear system, and for safety purpose, we also have ABS (antilock brake system) which is not connected to EMS (engine management system), EMS is the main component of the all automatic electric system which is connected with most of the sensors in a vehicle to reduce human effort and to minimize the loss of energy in a vehicle.

For direct fuel injection system and resistance to corrosion via petrol one mechanism is applied in the vehicle which is managed by EMS.

When a modern engine is operated it has components as well as sensors attached to it for the proper working of the engine, the components are listed in direction of flow of fuel 1) Fuel Tank, 2) Low-Pressure Fuel Pump, 3) Fuel Filter, 4) Pressure Control valve, 5) High-Pressure Fuel Pump, 6) Fuel

Injector, and some sensors such as 1) Throttle Position Sensor (located near throttle valve), 2) Manifold Absolute Pressure Sensor, 3) Oxygen Sensor, 4) Crankshaft Position Sensor, 5) Fuel Temperature Sensor.

When the engine starts and the driver applies force on the accelerator the throttle position sensor determines the magnitude of acceleration needed by driver sends the signal to EMS, EMS compiles the signal and sends another signal to the sensor near pressure control valve and the amount of

pressure can be solved by some mathematical and thermodynamic approach for which a special sensor is connected to EMS which is directly connected to fuel tank and fuel rail so that the excess of fuel can be directly transferred to fuel tank so that the error or failure in the system can be prevented.
