To save fuel while driving, consider the following tips:

1. Maintain a steady speed: Avoid frequent acceleration and braking. Smooth, consistent driving helps reduce fuel consumption.

2. Proper tire maintenance: Keep your tires properly inflated, as under-inflated tires can increase rolling resistance and reduce fuel efficiency.

3. Lighten the load: Remove unnecessary items from your vehicle, as extra weight can decrease fuel efficiency.

4. Use air conditioning sparingly: Air conditioning can increase fuel consumption. Use it wisely, and consider opening windows for ventilation at lower speeds.

5. Plan your trips: Combine errands to reduce the number of trips you make, and plan routes to avoid traffic and congestion.

6. Drive at a moderate speed: High speeds consume more fuel. Driving within the speed limit can significantly improve fuel efficiency.

7. Avoid idling: Turn off your engine if you anticipate a long stop, such as waiting for a train or at a drive-thru.

8. Maintain your vehicle: Regular maintenance, such as changing the oil, replacing air filters, and ensuring the engine is in good condition, can improve fuel efficiency.

9. Use cruise control: On highways, cruise control can help maintain a consistent speed and save fuel.

By following these tips, you can reduce your fuel consumption and save money while driving.

Main Components or Parts
1. Shafts–
There are usually 3 shafts used in a manual transmission that are-

(i) Main-Shaft-
It is the shaft that is also called the output shaft and is placed in front of the clutch shaft and in parallel to the lay-shaft. gears, gear lever along with the meshing devices such as dog clutches and synchromesh devices are mounted over this shaft.

(ii) Lay-shaft or Counter Shaft-
It is the shaft used as an intermediate shaft between the clutch shaft and the main shaft, it is usually mounted below and parallel to the main shaft, and act as an engine output carrier from the clutch shaft to the main shaft.
(iii) Clutch-Shaft-
It is the shaft that carries the rotational output from the engine’s flywheel to the transmission with the help of a clutch that engages and disengages the output from the engine.

2. Gears –
There are mainly 4 types of gears used in manual gearbox that are-

(i) Spur Gear: Used in old sliding mesh gearbox these types of gears have straight cut teethes.

(ii) Helical Gear: They are the modified version of the latter as they have angular cut teethes.

(iii) Bevel: They are best of all above gears having a conical cross-sectional area with angular cut teethes.

(iv) Idler-gear: It is the small gear used as a reverse gear usually mounted over the lay shaft.

3. Meshing Devices:
There are usually 2 types of meshing devices used in manual transmission-

(i) Dog Clutches: They are the devices used for meshing of gears in constant mesh gearbox.

(ii) Synchromesh Devices: They are the devices which are used in synchromesh gearbox for the meshing, these devices provide smooth shifting of gears.

4. Gear lever-
It is the lever used by the driver to shift a gear.
