New Churchill Motors is your best car service outlet in Churchill, Vic, for all your Electronic Fuel Injection (EFI) servicing and repairs. To perform a thorough inspection and analysis.

During a typical EFI service our mechanics will inspect your vehicle and identify if your car is affected by common vehicle problems, including:

• hesitation
• lack of power
• poor fuel economy
• poor acceleration
• poor engine performances during cold
• stalling at cold temperatures
• pinging engines
• carbon build-up

Untreated buildups and problems can increase over time and require costly car service and potentially preventable engine repairs, if you contact New Churchill Motors for timely car inspection.

In an internal combustion engine, an EFI is the system for mixing fuel and air. For the last few decades, EFI has gradually replaced caburetors to become the most typical system used for fuel delivery in fuel based engines.

In an EFI, a fuel pump pushes the fuel coming from a tank into different injectors creating sufficient pressure for the injectors to deliver accurate amount of fuel. Pump pressure and fuel volume flowing through must meet vehicle manufacturer standards. Failing to meet requirements, the engine performance and economy could be reduced, at the same increasing fuel consumption and emissions.

When inspecting and servicing EFI systems, electric fuel pumps are the primary concern area. Regular wear and tear under normal operating conditions will cause fuel pumps to fail over time. If rust or other type of dirt settle on inlets past filters or contaminate the pump, the repairs will be needed much sooner. This is why it is crucial to inspect your car at scheduled intervals and keep regular contact with New Churchill Motors.

Throttle Body Injection and Port Injection are the two major types of fuel injection are used in modern gasoline engines. Both operate by the same principles, yet look very different.

Port Injection System sends fuel directly into individual cylinders. Various sensors are located throughout the engine compartment to detect airflow, vacuum, temperature and exhaust.

Throttle Body Systems have two injectors inside an aluminium housing, mounted to the intake manifold. Nearly all required sensors are located in the same aluminium housing.

The major differences between both systems is price and performance. The far superior port injection systems are also considerably more expensive as the individual sensors must be manufactured separately so that each component can be mounted independently. With each cylinder receiving fuel individually, the computer can control fuel consumption and power much more efficiently. Throttle body systems are cheaper to manufacture, however offer lower performance.

The key to an efficient electronic fuel injection system is the computer. All electronic fuel injection systems utilise a computer to receive information from sensors and, based on information received, send necessary voltage to fuel injectors. Various manufacturers have different names for the electronic fuel injection computer:

• Electronic Control Unit (ECU)
• Electronic Control Module (ECM)
• Power Control Module (PCM)
• Brain Box (typically used in used parts industry)
