What are the advantages of using fuel injection?
The Benefits of Electronic Fuel Injection
- More Power. EFI-equipped engines provide higher power and torque than a carbureted version of the same engine.
- Lower Fuel Consumption and Emissions.
- Increased Reliability.
- Less Maintenance, Less Downtime.
- Improved Starting.
Does fuel injection improve performance?
From the above review, it can be found that with the increase of fuel injection pressure, for both diesel, biodiesel or blend fuel, the performance is improved, the fuel consumption is reduced, the major emissions such as HC, CO and PM are reduced but with a slight increase in NOx emissions.
What are the cons of using direct fuel injection?
Just as plaque can build up in your arteries, reduce blood flow to your heart and lead to a heart attack, carbon buildup on your car’s intake valves reduces fuel flow to the engine and can lead to failure. The biggest drawback of direct fuel injection is DI can lead to clogged fuel systems and engine carbon fill up.
What are the effects of early and late fuel injection?
Early injection timing leads to longer ignition delay which results in accumulation of large amount of evaporated fuel before the start of combustion. Longer ignition delay is due to lower values of pressure and temperature inside the cylinder during the initial period of fuel injection at advanced injection timings.
What are the two main types of electronic fuel injection systems?
Port or Multi-Point Fuel Injection. Sequential Fuel Injection. Direct Injection.
What is Mpfi and its advantages?
Advantages of multi point fuel injection system? The multi-point fuel injection technology improves fuel efficiency of the vehicles. MPFI uses individual fuel injector for each cylinder, thus there is no gas wastage over time. It reduces the fuel consumption and makes the vehicle more efficient and economical.
What are fuel injection strategies?
The fuel injection strategies include single injection with heavy EGR, and early multi-pulse fuel injection under low or medium engine loads respectively. The empirical studies have been conducted under independently controlled exhaust gas recirculation, intake boost, and exhaust backpressure.
How can I improve my engine performance?
How to Increase Engine Performance
- Use Synthetic Lubricants and Additives.
- Check Your Ignition.
- Install Larger Throttle Body and Injectors.
- Ensure Good Compression.
- Implement a Cold Air Intake (CAI)
- Replace Your Exhaust Manifold With Real Headers.
- Use Forced Induction (aka Power Adder)
- Maintain Your Vehicle.
What is the difference between GDI and MPI?
Compared to conventional MPI engines of a comparable size, the GDI engine provides approximately 10% greater output and torque at all speeds. In high-output mode, the GDI engine provides outstanding acceleration. The following chart compares the performance of the GDI engine with a conventional MPI engine.
What is the difference between EFi and MPI?
EFi, MPFi, GDi – EFi stands for Electronic Fuel injection (EFi) whereas MPFi or MPi stands for Multi-Point Fuel injection and GDi stands for Gasoline Direct Injection. All these are the types of fuel injection systems which the gasoline or petrol fuel engines mainly use.
What happens when fuel is injected too late?
A small late-injection of diesel (<7.5 mg/cycle) had little impact on in-cylinder pressure and heat release rate (HRR). However, enhanced or retarded late-injection led to a decline in peak gas mean temperature (GMT) but an increase in later combustion temperature.
What is fuel injection timing?
Injection timing, also called spill timing, is the moment when diesel fuel enters the cylinder during the combustion phase. When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs.
