Hyundai Petrol Engines To Be Effective Like Diesel
Technology is the promising factor in new age cars. Hyundai, in the wake of greener, efficient cars is developing a gasoline direct compression ignition (GDCI) engine. The new generation 1.8 litre petrol engine from Hyundai is said to work like diesel, but burns petrol. Hyundai expects the GDCI engine to deliver 25 percent gain in fuel efficiency over a comparable petrol engines.
Diesel prices currently average about 25 rupees more per litre than regular petrol in India. New car buyers can soon expect lower costing and improved fuel efficient petrol cars from Hyundai.

Owing to the common perception in India, new car buyers prefer picking up a diesel car as opposed to a petrol one, citing superior fuel efficiency in the latter. And despite the pricier labels diesel cars boast of when compared to its petrol counterparts, it is still the preferred vehicle of choice. With that said, Hyundai could break into crucial diesel sales with the launch of this GDCI petrol engine.
And the good news is, from a mileage, cost and maintenance standpoint, it is expected to be cheaper than currently available petrol cars.

For example, the Hyundai Sonata (petrol) is currently priced between 18-20 lakhs (ex-showroom Delhi) with a 2.4 litre GDI engine. With this new GDCI engine, we may see Hyundai rolling out the enhanced Sonata beginning at 15 lakh onward.
How does a Hyundai GDCI petrol engine work?
The new petrol engine works on a compression ignition platform, which is the pattern of flaming in diesel engines. In this type of ignition, the pressure in the cylinder ignites the fuel, whereas a spark plug burns the fuel in a petrol engine.
The Hyundai GDCI engine will operate without spark plugs. Instead, it adopts a supercharger and a turbocharger. The exhaust valves will be cut out to open twice instead of once per cycle. This extra window draws in heat, which along with the pressure of being compressed in the cylinder, ignites the petrol.
When can we expect the Hyundai GDCI petrol engine?
By mid next year, we expect Hyundai to start testing these engines in the Sonatas. The technology looks promising. For now, its a clear indicator, that Hyundai is not a fast follower, setting their sights on being the leader instead.
