Types of fuel injection systems:
A fuel injection system is a vital component in a car's engine that delivers fuel to the combustion chamber. It is responsible for providing the right fuel to the engine at the right time to ensure efficient, accurate, and reliable operation, making it the preferred system in modern vehicles.
Single-Point or Throttle-Body Injection:
Single-point injection, or throttle body injection, uses a single injector in the throttle body to deliver fuel to all cylinders. The fuel is injected into the throttle body and mixed with air as it passes through the intake manifold and into the cylinders. It was commonly used in older vehicles and is now less common due to its limited precision and efficiency.
Port or Multipoint Fuel Injection:
Port or Multipoint Fuel Injection is also known as an indirect Injection system. In the port injection system, the fuel is injected into the intake port, rather than directly into the engine cylinder.
In a port fuel injection system, each cylinder has a fuel injector located in the intake port of the engine, which sprays fuel into the intake manifold just before the intake valve opens. The fuel mixes with the incoming air and is drawn into the cylinder when the intake valve opens.
Direct Injection:
In a Direct Injection system, fuel is injected directly into the combustion chamber of each engine cylinder, rather than into the intake valve, so that it looks like a diesel engine, where the injector will spray fuel directly into the cylinder. Direct injection is used in both petrol and diesel engines.
Typically, the fuel is injected during the compression stroke of the engine. This allows for better control over the fuel and air mixture and can result in improved engine efficiency and performance.
Dual Injection system:
Dual-injection systems use two different methods of injecting fuel into the engine: direct injection and port injection. It is commonly found in modern gasoline engines and is designed to Improve Engine Efficiency.
In a dual injection system, there are typically two types of injectors: a high-pressure direct injector and a low-pressure port injector. The direct injector injects fuel directly into the combustion chamber, while the port injector injects fuel into the intake port of the engine.
