Hyundai's New Theta Engine with GDI (Gasoline Direct Injection) Technology

Hyundai Motor opens a new era in  gasoline engine technology that GDI engine is optimized to deliver the  best quality both floating piston and  cooling jet to reinforce durability  balance shaft module for nbh improvement  roller type chain system that minimizes friction and dual cv VT system for  excellent fuel efficiency and  performance that GDI engine realizes the high efficiency and  performance through the precise engine  control right.

After the engine is great  for the start the fuel pressures deeply  increases up to the precise  amount of fuel is directly injected into  the cylinder  thanks to the optimized white bowl on  the piston and the injection during the  compression stroke an optimal mixture of  the fuel and air is formed near the  spark plug and this leads to a clean  ignition.

After the start the split injection  helps to obtain a stable combustion even  with the late ignition to increase the  exhaust energy this increased exhaust  energy lights off the catalyst faster by  more than % thanks to the fast light  off the exhaust emission is reduced in  normal driving conditions ...
