2. Definition Of
Transmission System :
The mechanism that transmits the
power developed by the engine of.
automobile to the engine to the driving
wheels is called the. TRANSMISSION
SYSTEM

3. Types of transmission system
The transmission system are classified on the basis of engine location .they are as
follows.
1)front engine front wheel drive
2)front engine rear wheel drive
3)rear engine rear wheel drive
4)four wheel drive

4. front engine front wheel drive
FWD means that the power from the engine is delivered to the front wheels of your vehicle. With FWD, the front
wheels are pulling the car and The rear wheels don't receive any power on their own. The pros of a FWD vehicle are that
they typically gets better fuel economy and emits less carbon dioxide.

5. front engine front wheel drive advantages,disadvantages
Advantages
● Front-wheel drive reduces weight
● decreases production costs
● improves fuel economy compared to a rear-wheel-drive system
● There is need of propeller shaft
● It has more stability
Disadvantages
● Exhaust gases affect the passengers
● It reduces tractive effort
● The road gripness is less while the vehicle goes down

6. front engine rear wheel drive
A front mid-engine, rear-wheel-drive layout (FMR) places the engine in the front of the vehicle but behind the front
axle, which likewise drives the rear wheels via a driveshaft

7. front engine rear wheel drive advantages,disadvantages
advantages
● Rear-wheel drive (RWD) front engine cars are balanced better
● Their weight is more evenly distributed,
● making them less prone to oversteer as compared to RWD rear-engine cars,
● less prone to understeer as compared to FWD front-engine vehicles
Disadvantages
● Exhaust gases affect the passengers
● Length of the vehicle increases

8. rear engine rear wheel drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine
drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars.

9. Rear engine rear wheel drive advantages,disadvantages
Advantages
1. Short driveline because the engine, gearbox and final drive can be built into a single unit.
2. A majority of weight at the rear of the vehicle gives improved traction during hill climbing and
acceleration.
3. It has a simple drive shaft layout compared to a front wheel drive.
4. The exhaust gases, fumes, engine heat and noises are carried away from passengers.
Disadvantages
1. Space for luggage is reduced.
2. Steering is difficult in slippery conditions.
3. It has a restricted luggage compartment due to narrow front which houses the fuel tank also.
4. Natural air cooling is not possible because it requires a powerful fan.
5. Long linkages are required for the engine, clutch and gear box controls
