Message:: [QUOTE="หนูหริ่ง, post: 177518, member: 38200"]A MIVEC MD (Modulated Displacement) version was also available. The MD engine makes the same power but with superior fuel economy. Unfortunately, it appears that the MD version was dropped in 1996. The MD system is an early form of cylinder deactivation which involves closing the intake and exhaust valves at light engine load. This means the driver must open the throttle further to maintain power and, as a result, pumping losses are reduced and active cylinder pressures are increased. This results in greater efficiency and fuel economy. Depending on conditions, the MIVEC-MD system can reduce fuel consumption by 10 - 20 percent. MIVEC MD = Modulated Displacement. The ECU is able to shutdown 2 cylinders on cruising speeds for fuel economy. ขออนุญาติไม่แปลนะคับ<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /> ผมดูแล้วมันคล้ายๆเทคโนฯเครื่องรถไอ้กันบางรุ่นเมื่อก่อนอ่ะ อย่างคาดิแลคบางรุ่นอ่ะ[/QUOTE]
