Advanced direct injection combustion engine technologies and development

  PREFACE : Over the last decade, significant progress has been made in the development of  direct  injection  internal  combustion  engines.  It  may  have  been  by coincidence  that  direct  injection  technology  was  developed  and  applied almost simultaneously to spark ignition (SI) gasoline engines and light-duty diesel engines in the mid-1990s, but the direct injection technology had been adopted in both engines for the same reason – to increase the efficiency of internal combustion (IC) engines for automotive applications while improving their performance. However, the route to growth and market penetration has proved more haphazard in the case of direct injection SI engines, owing to relatively  high  cost,  lower  than  expected  gains  in  fuel  economy  and  full load  performance,  their  complexity  and...

gearbox

Understanding the components of a gearbox is key to learning how a manual transmission works.
1. Input Shaft: This shaft connects to the engine and delivers power to the gearbox.
2. Output Shaft: The output shaft transfers the modified torque and speed to the wheels.
3. Gears: Different gears allow power to be transmitted at varying speeds and torque levels.
4. Counter Gear & Shaft: These provide a mechanical link between the input and output shafts.
5. Shift Rod & Shift Fork: These components help move gears into position when changing speeds.
6. Idler Gear: Typically used to reverse the direction of rotation.
7. Stick Shift: The driver operates the stick shift to engage or disengage gears.
8. Gearbox Case: This housing contains and protects all the gearbox components.
9. Extension Housing: This part connects the gearbox to the driveshaft.
The manual gearbox efficiently distributes engine power to ensure smooth and controlled driving.
