Fuel Injection

Fuel injection is a technology used in internal combustion engines to mix the fuel with air before burning. 

The use of fuel injection will increase the engine power when compared with the use of a carburetor, because the fuel injector makes homogeneously mixed. This, makes the fuel injection can control the mixing of fuel and air that is more precise, both in proportion and uniformity. 

Fuel injection can be either mechanical, electronic or a mixture of both. Beginning of a mechanical system, but around 1980 began many uses electronic systems. Modern electronic system uses many sensors to monitor the condition of the engine, and an electronic control unit calculates the amount of fuel required. Therefore, the fuel injection can increase fuel efficiency and reduce pollution, and also provide more power output.

Usage purpose injection system

The main purpose injection system usage is extremely diverse. Some of the usage purpose, among others: 

Output power vehicles 

Fuel Efficiency 

performance 

The ability to use alternative fuels 

durability 

Subtle use of vehicles 

Cost initial 

Cost of care 

The ability to diagnose 

The ability to operate at anywhere and anytime 

Practicality machine setup

Excess injection system

Low exhaust emissions 

Complete combustion in the combustion chamber, so that the exhaust emissions produced relatively fewer moreover equipped exhaust catalytic converter. 

Greater power 

Construction injector in the intake manifold so that the proper mixing of fuel is more homogeneous. 

More fuel-efficient 

Air-fuel ratio combustion greatly affect the perfection of the machine. Standard AFR on the motor is 14.7: 1, which means the air 14.7 and 1 gasoline. AFR can change, for example when a cold engine AFR 5: 1, at idle AFR 11: 1, acceleration 8: 1, and when the use of economical 40-60 km / h AFR 16-18: 1. So the fuel consumption of the motor is more efficient than a carburetor injection. 

Does not require a choke (choke)

Fuel injection fitted temperature sensors to report the temperature of the engine to the engine control module (ECM) will command the injectors to enrich the fuel mixture to the engine temperature is cold. 

Treatment is more practical

Fuel injection technology maintenance free concept. At the time of servicing, cleaning is done only on the air filter, spark plugs, and valve settings.

Disadvantages injection system 

Acceleration is less responsive 

The occurrence of a long process of regulating the amount of air sensors and reports from other sensors, thus requiring a longer time to accelerate. 

Lack of experts 

Fuel injectors including new technologies, not all are able to improve the public workshop in the event of problems with the vehicle. 

Sensitive to impact / shock 

All devices mainly use the electronic engine control module, making it susceptible to death when experiencing shock or concussion. In the event of this, the vehicle is not likely to be revived, because of damage to the engine control module. The cost of repair costs are still relatively expensive. 

Sensitive fuel 

Micro-sized injector tip, so that the fuel injection system is blockage due to dirty fuel. This will affect the performance of the vehicle so that the fuel into the combustion chamber slightly, 

sensitive electrical 

Vehicle condition is reported by the sensors, and the sensors are connected using cables have connector. Connectors are often the cause of reporting sensors to the engine control module to be fucked. Delivery reports the sensor to the engine control module uses a security system. If the cable connector corrosion occurs, it will increase the security system so that reports of the sensor resulted in the engine control module to function improperly and may result in damage caused by unstable power supply.
