| 41. | The outdated engine also had little torque available at lower engine speeds, and was noisy.
|
| 42. | Engine speed was increased but with little effect, except for a doubling of fuel consumption.
|
| 43. | At low engine speeds vanes are almost closed creating a narrow passage for the exhaust.
|
| 44. | The engine speed was limited to 4, 000 rpm.
|
| 45. | Maximum engine speed is listed at 7000 RPM.
|
| 46. | Maximum torque was increased slightly, but more important, that torque became available at lower engine speeds.
|
| 47. | Fuel injection is sequential and regulated with air mass per combustion and engine speed as parameters.
|
| 48. | Variable valve timing assures that most of this power is available at very low engine speeds.
|
| 49. | This is beneficial at higher engine speeds because of a reduction in the aforementioned valve float.
|
| 50. | Many cars also have computers that keep track of engine speed, car speed and the like.
