\u2022 Based on the coordination with the electric variable valve timing control and by increasing the amount of overlap during high engine loads, nitrogen oxide (NOx) occurring largely at high temperatures is reduced by re-circulating exhaust gas into the combustion chamber, which reduces combustion temperature.<\/div>\n<\/td>\n<\/tr>\n
\n
Electric variable valve timing control<\/div>\n<\/td>\n
\n
\u2022 The PCM determines the optimum intake valve timing according to the engine operation conditions, and sends the motor drive signals to the electric variable valve timing driver.
