What is indirect injection in diesel engine?

An indirect injection diesel engine delivers fuel into a chamber off the combustion chamber, either a prechamber or swirl chamber, where combustion begins and then spreads into the main combustion chamber. …

What’s the difference between direct and indirect fuel injection?

Indirect injection or (IDI) is when the fuel injection is not directly injected into the combustion chamber. With a direct injection system or (DI) the fuel is injected directly into the combustion chamber, usually on the top of the piston which is designed to control the spread of combustion.

How is petrol engine different from diesel engine?

The main difference between diesel and petrol engines is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely solely on heavily compressed air. In petrol engines, the compression ratio is generally much lower, because they rely more on the spark plug to begin the power phase.

Is it better to put petrol in a diesel or diesel in a petrol?

A diesel fuel pump operates on very fine tolerance at high pressures and is lubricated by diesel fuel. When petrol is added to diesel it reduces its lubrication properties, which can damage the fuel pump through metal-to-metal contact and create metal particles causing significant damage to the rest of the fuel system.

Is fuel different from diesel?

Conventional diesel and petrol are both produced from mineral oil, but the precise refining methods vary. Per litre, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel.

How can you tell diesel from petrol?

Diesel is more dense than petrol. you can simply check by putting finger in it. petrol will evaporate more quickly but diesel will hardly evaporate while on your finger. Color of container is also a way to differentiate petrol and diesel.

Can you mix diesel and petrol?

Misfuelling by putting petrol in a diesel car is much more common – and the consequences can be much more dramatic. Possible warning signs include jerky acceleration as the petrol damages the pumps in your car’s engine, as well as smoke coming out of your exhaust. You might also experience your engine misfiring.

Can I use a diesel can for petrol?

Registered. As long as there is no diesel left in there, it shouldnt be a problem if your going to fill the can up to the top… the ratio of petrol to diesel in that can will be nothing to worry about..

What are the problems with direct injection?

Another problem with direct injection is with ethanol fuel. Ethanol is known to speed up the corrosion rate of some metals that are used in an engine. With the higher pressure of a direct injection engine, and thanks to the fuel injector being exposed to in-cylinder explosions, there’s a higher chance of a problem or failure.

What’s so great about direct injection?

Advantages of Direct Fuel Injection Combined with ultra-precise computer management, direct injection allows more accurate control over fuel metering , which is the amount of fuel injected and injection timing, the exact point when the fuel is introduced into the cylinder.

What is indirect injection?

Indirect injection is a diesel engine injection system in which ignition is started before the burning mixture enters the main combustion chamber . Indirect injection engines are cheaper to build and it is easier to produce smooth, quiet-running vehicles.

Who makes GDI engines?

The 1996 Japanese-market Mitsubishi Galant was the first mass-produced car to use a GDI engine, when a GDI version of the Mitsubishi 4G93 inline-four engine was introduced. It was subsequently brought to Europe in 1997 in the Carisma. It also developed the first six-cylinder GDI engine, the Mitsubishi 6G74 V6 engine, in 1997.
