How does a GDI engine work in passenger cars? Is it worth investing in a Hyundai and KIA gasoline engine?

In order to improve the comfort of the engine and increase its efficiency, engineers are constantly working on modern technological solutions. The key issue is the reduction of emissions of exhaust gases and toxic substances. Optimizing the process of combustion of the mixture in the cylinders helps to take care of the environment. The GDI engine installed by Hyundai and KIA is equipped with direct fuel injection, and precise mixture preparation has many advantages. Firstly, the machine works much more efficiently and more cultured. In addition, high pressure T-GDI reduces fuel consumption by up to 20%. Will you win if you choose a car with a GDI engine? Does this unit have any major drawbacks? Check!

GDI engine - what is the abbreviation?

1.6 GDI engines are often found in Mitsubishi, Hyundai Tucson and Kia Sportage vehicles. The new GDI engine has gasoline direct injection, which makes LPG installation more expensive for this design. GDI is different Gasoline with direct injectioni.e. direct injection of gasoline. This is a specially developed technology for supplying fuel to the cylinders. Thanks to this, not only the culture of the engine is improved. In the case of the 1.6 GDI G4FD models, there was a significant reduction in fuel consumption and improved dynamics at lower speeds. The KIA GDI engine is built similarly to other transmission models. Hyundai Motor Group uses the GDI engine most often, especially in the 1.6 GDI G4FD versions.

How does a GDI engine work? A little information

The practical operation of the injectors of the 1.6 T-GDI and 1.6 CRDI engines is simple. When driving as a vehicle user, don't worry about engine culture. The high flexibility of power transmission ensures trouble-free off-road driving. GDI drives are different culture of work. Even longer rides at lower revs are no problem. When you press the gas pedal, the car immediately reacts without unnecessary delays. GDI engines offer good acceleration and overall performance. KIA Ceed, Mitsubishi Carisma and many other cars with GDI also have huge maximum torque. However, in most models, the GDI engine is almost inaudible.

Unit design and GDI engine - what does the engine look like in reality?

GDI engines with a direct injection fuel system have the following systems:

• high pressure fuel pump;
• High pressure pump;
• sensors that record the current pressure;
• high pressure gasoline sprayer;
• special pistons of the same size;
• fuel pressure regulator.

These are the main elements of the engine with direct injection of gasoline into the combustion chamber. Kia also introduced the 160 hp T-GDI engine. This is a dynamic unit that is suitable for both sedans and station wagons. Impeccable timing and very good acceleration are the main features of this engine. What other advantages do the drives described in the text have? Are there any disadvantages as well?

Benefits of GDI engines

There are many benefits of GDI engines worth knowing about every day. which the? Here are a few of them. First of all, the compounding process directly increases the power by up to 15%. Manufacturers of GDI engine blocks are committed to reducing environmental pollution. These environmental installations are characterized by a simple design and a relatively good level of reliability.

Disadvantages of GDI 1.6 engines

Of course, GDI engines also have many disadvantages that you need to be aware of. At the same time, the main disadvantage of the unit is its price. As a car owner, you will pay a much higher amount just for the maintenance and operation of the engine. Here are other disadvantages of this internal combustion engine that can be felt during operation:

• the need to purchase engine oil from a higher price range;
• more frequent replacement of air filters;
• problematic nozzles without the possibility of detachment for cleaning;
• obligation to have a catalyst.

Before deciding on a car with a GDI engine, weigh all the pros and cons of this unit. Currently, many manufacturers install these modern and environmentally friendly units on their cars. However, consider whether you can ultimately afford to maintain such a vehicle and cover all operating and maintenance costs.
