What is the difference between direct injection and indirect injection?
Direct injection injects the fuel charge directly into the combustion chamber, (more efficient). Indirect injection injects the fuel charge into the intake port behind the intake valve, or in the case of Throttle Body injection, into the center of the intake manifold for distribution to the cylinders. Indirect injection was much cheaper to produce, but resulted in higher emissions and reduced power relative to direct injection.Source(s):ASE Master Technician, 46 years experience.
Is fuel injection for diesel engines more efficient?
diesel only comes in fuel injection, the fuel needs high pressure to ignite, and cannot only be sucked in like with a carburator on a petrol engine
Which engine is superior- direct injection turbo or indirect injection turbo?
Direct is designed to low emissions and should allow for higher performance due to better atomization and a more accurate air/fuel mixture.
What is best carbs or fuel injection for triumph motorcycle?
Fuel injection provides a smoother, more controllable propulsion and generally is much more efficient and faster. I have had two carbed bikes and they are a pain for maintenance. Get the fuel injected and you'll be happy. Though it is relatively new for motorcycles, it is becoming more commonplace. (Fall 09).
What does fuel injection do?
In a conventional internal combustion engine there are two typical methods for delivering fuel to the combustion process: 1. carburation 2. fuel injection. Current fuel injection systems are computer controlled, taking into consideration engine temperature, air pressure, air volume, vehicle speed, throttle position, engine RPM and anything else that might be considered even slightly significant. Carburated systems only considered engine vacuum and throttle position, with an indirect method for determining when the engine was first being started. Fuel injection actually monitors what's going on in the engine, delivering the proper amount of fuel to provide maximum power for the minimum amount of fuel. Fuel injection is far more efficient and produces far fewer unwanted emissions.
Which is more fuel system technique Multi Point Fuel Injection or sequential electronic fuel injection?

What is DI?
DI means Direct Injection. Diesel engine depending on combustion categorised in Direct injection or InDirect injection Engine. Direct Injection engine combustion takes place directly above the piston. But indirect injection combustion initially takes place pre-combustion chamber and after transfered to above piston.DI engine more fuel efficient, easily start in cold condition, But Noise more.
What is injection engine?
Assuming that you are asking about fuel injection, fuel injection is an alternative to using a carburetor to get the fuel to the cylinders. There are several different types of fuel injection. Probably the three most common are throttle body fuel injection, port fuel injection and direct fuel injection. Throttle body fuel injection uses something that looks a good deal like a carburetor but has one, two or more electrical operated solenoid valves that spray a metered amount of fuel into the incoming combustion air. Port fuel injection is similar but the fuel is injected into the intake manifold port of each cylinder. Port fuel injection can provide improvements in emissions, fuel economy and performance if done correctly. Both throttle body and port fuel injection are low pressure systems. Direct fuel injection injects the fuel directly into the combustion chamber and is a high pressure system. Direct fuel injection can provide even more improvement in emissions, fuel mileage and performance and is becoming more and more common in passenger vehicles. As a further note, most, if not all, compression combustion (like a diesel engine) engines use high pressure direct fuel injection.
What feature in a car fuel makes it more fuel efficient?
A car has to be fuel efficient. It means it has to completely burn the fuel.
How are cars made more fuel efficient?
Lighter weight, more aerodynamic, and more fuel efficient engines, transmissions, and tires.
Do direct flights or indirect flights use more fuel?
Indirect flights would use up more fuel because they have more take off and landings than would a direct flight.
What is an sfi engine?
SFI (Sequential Fuel Injection) also called as SEFI( Sequential Electronic Fuel Injection) . Unlike the Multi Point fuel injection (MPFI) system, SEFI has separate fuel injectors for each cylinder which inject fuel more precisely increasing the fuel efficiency.
