What You Need to Know About “Fuel Injection/Induction Service”
Fuel injection is the spraying of fuel under pressure into the engine’s airstream or cylinders. It differs from carburetion in that carburetors keep the fuel supply at basically very low pressure and rely on the pressure drop in the venturi (carburetor) to draw the fuel in, as opposed to injection which sprays it in under various pressures.

Your induction system is basically the airflow system into the cylinders that includes the control element of your throttle plate along with entryways for exhaust gas from the EGR system and vapors from the crankcase via the PCV system.

What Carlsbad Auto Service Can Do For You!
An injection and induction system cleaning at Carlsbad Auto Service consists of a cleaning of the fuel injectors and of the carbon deposit build up on the engine valves and throttle plate area. This ensures your engine will receive improved fuel flow into the combustion chamber, which will give you better fuel mileage and lower emissions.

More Facts About “Fuel Injection/Induction”
All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke.

On petrol engines, fuel injection replaced carburetors from the 1980s onward. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created in the intake manifold to draw the fuel into the airstream through a venturi (carburetor).

In non-Diesel internal combustion engines, Gasoline Direct Injection (GDI), also known as Petrol Direct Injection, Direct Petrol Injection, Spark Ignited Direct Injection (SIDI) and Fuel Stratified Injection (FSI), is a variant of fuel injection employed in modern two-stroke and four-stroke gasoline engines. The gasoline is highly pressurized and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that injects fuel into the intake tract or cylinder port. Directly injecting fuel into the combustion chamber requires high pressure injection whereas low pressure is used to inject fuel into the intake tract.

In some applications, gasoline direct injection enables a stratified fuel charge (ultra lean burn) combustion for improved fuel efficiency and reduced emissions.
