There are so many engine terms out there depicted on cars and it can be daunting to keep track of all of the new terms and what they all mean. Here is a list discussing a few of them.

VVT-i:

Variable Valve Timing with intelligence.

This system was introduced by Toyota and is still being used in most of their vehicles. Essentially what it does is vary the air-fuel mixture to the engine ensuring it runs in optimal condition depending on how the car is being driven.

TSI:

Turbo Stratified Injection

TSI engines as small engines with turbo charges ensuring you get a punchy engine with excellent fuel economy. This sort of engine combines Diesel and Petrol tech and provides a better general experience.

DOHC: 

Dual Overhead Cams

This means that an engine has two cams on each bank of the cylinder head, there are four valves per cylinder which means better performance and higher speeds for the engine as there is a richer air-fuel mixture.

K10C:

This doesn't necessarily stand for anything other than a codename for an engine made by the Japanese - this can be a 3 or 4-cylinder engine. A K10C and a K10B engine which produce the same power but different torque figures. These engines are mostly the same and produce similar figures across the board, in their N/A state that is. 

The main benefits of this engine are that it's lighter, generates fewer emissions and generally provides a pleasant driving experience as it's a small but punchy engine. The key benefits of the K-series engines are that they're lighter in weight, generates fewer emission and improves the overall driving capability.

GDi:

Gasoline direct injection

Gasoline direct injection means the fuel is injected directly into the combustion chamber instead of traditional intake ports. The benefit of this is more power as the fuel goes directly to the cylinder block which in turn means more efficiency. It also means that you'll have a decrease in emissions and improved fuel economy. 

However, due to modern-day fuel, there are a lot of detergents and carbon traces in them which could lead to a build-up of these elements. When this happens airflow to the cylinder heads is restricted meaning the air-fuel mix is not optimal, thus meaning you lose the benefits of this engine. 

GDI engines - found in cars like the Kia Seltos, Kia Sportage.
