Spark plugs are a thing of the past if Hyundai is.

Electric drive with here and there a touch of hydrogen. The are the focal points of the contemporary car industry, but let’s not forget that the old-fashioned internal combustion engine is not yet fully developed, and vehicle manufacturers this concept continue to improve. In fact, Hyundai has a new engine announced that cars 25 percent more fuel efficient than comparable gasoline engines.

Spontaneous combustion

Okay, so far the have not yet proved zuinigheidsclaims claims, let’s see how it works. The basis is a direct-injection four-cylinder engine with 1.8 liter capacity. However, in the cylinder head, no spark plugs to find. The mixture of gasoline and air is burned by compression. Spontaneous combustion at a regular peutmotor not want to have (bargaining), but you are here. Hyundai calls it ‘GDIC’, or Gasoline Direct-Injection Compression.

The engine features a supercharger for the lower revs. This is because there is too little exhaust gases are produced to a turbo at low engine speeds to drive. Once running the compressor ‘gebypassed ” and take a turbo work on. The ignition is caused by the higher pressure in the cylinder – the engine has a compression ratio of 14.8:1 and the fact that the exhaust valves twice a arbeidsslag open. The second opening of the outlet, whereby exhaust gases to flow back provides extra heat in the cylinder causing the fuel mixture explodes. Et voila, we have a arbeidsslag where no bougievonk to pass has come.

4,500 rpm

In the dyno setup know the engine is about 180 hp to generate and they pick up the aforementioned fuel savings of 25%, but the downside is that the speed up to 4,500 rpm, and the GDIC-block as a diesel will sound. Hyundai says, however, that the sound can somewhat soften by the injection time to adjust. But it remains a petrol engine with a diesel clatter. Should we want to?

The engine is the next year in the practice tested in a fleet of Sonata’s, because the Koreans have absolutely the intention of this technique to the market. Partners with the car manufacturer to help the American Delphi and the University of Wisconsin. In short, soon you will hear dieselende Hyundai’s rattle which is simply gasoline on the burn.
