通過(guò)排氣凸輪軸上的電子氣門(mén)升程切換系統(tǒng)以及進(jìn)氣和排氣凸輪軸上的可變氣門(mén)正時(shí),實(shí)現(xiàn)對(duì)每個(gè)氣缸氣體交換的優(yōu)化控制。較小的凸輪輪廓僅用于低轉(zhuǎn)速,此功能有以下好處:
① 優(yōu)化氣體交換;
② 防止廢氣回流到之前的180°排氣缸;
③ 入口打開(kāi)時(shí)間更早,填充程度更佳;
④ 通過(guò)燃燒室內(nèi)的正壓差減少余氣;
⑤ 提升響應(yīng)性;
⑥ 在較低轉(zhuǎn)速和較高增壓壓力下達(dá)到更高的轉(zhuǎn)矩。
Through the electronic valve lift switching system on the exhaust camshaft and the variable valve timing on the intake and exhaust camshafts, the optimal control of gas exchange of each cylinder is realized. The smaller cam profile is only used for low speeds, and this feature has the following benefits:
① Optimize gas exchange;
② Prevent the exhaust gas from flowing back to the previous 180 ° exhaust cylinder;
③ The inlet opening time is earlier and the filling degree is better;
④ The residual gas is reduced by the positive pressure difference in the combustion chamber;
⑤ Improve responsiveness;
⑥ Higher torque at lower speed and higher boost pressure.
