What is the purpose of PGM-FI system?

The key behind this system is the constant monitoring and assessment of engine, atmospheric and riding conditions, and the use of this data to control the quantity of fuel injected into the engine. In technical terms, PGM-FI is an n-alpha mapped injection system.

Do all Hondas have PGM-FI?

Around 91% of cars are believed to be compatible, including: All petrol cars manufactured after 2011. All Honda petrol cars equipped with Honda PGM-FI Electronic Fuel Injection — fitted on all models from the 1996 model year.

What is PGM-FI main relay on Honda Accord?

The PGM-Fl main relay actually contains two individual relays. This relay is located at the left side (LHD) or right side (RHD) of the cowl. One relay is energized whenever the ignition is on which supplies the battery voltage to the ECM, power to the fuel injectors, and power for the second relay.

Does my Honda have an electronic control fuel injection system?

All Honda petrol car models produced post-1996 (year model) are fitted with electronic fuel injection (Honda PGM-FI) and will be compatible with the new E10 fuel.

What is fuel injection vs carburetor?

A fuel injection system precisely delivers fuel in the right amount and can tweak it according to several parameters resulting is less fuel wastage and better fuel efficiency. A carburettor is unable to adjust the fuel ratio according to the engine conditions.

What Honda cars have PGM-FI?

What year did Honda start using fuel injection?

October 3, 2003-Honda Motor Co., Ltd. announced today that it has developed the world’s first electronically controlled fuel injection system (Honda Programmed Fuel Injection, or ‘PGM-FI’) for use in 4-stroke, 50cc engines.

Is Honda VTEC fuel injected?

The VTEC TURBO uses direct injection technology to inject fuel directly into the cylinders, lowering the temperature within the cylinders by the gasoline’ s vaporization heat. High tumble intake ports that strengthen intake airflow, and tumble flow maintaining pistons, allow fuel to be quickly and efficiently burned.

What causes a main relay to fail?

Even in low-level signal applications, accidents and faulty UUTs can cause relay failures, and inrush currents, caused by hot-switching capacitive loads, and voltage spikes, caused by hot-switching inductive loads, accelerate relay aging.

Does fuel injection increase horsepower?

The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
