Hybrid Bus
Hybrid Electric Configurations for Buses• Series Hybrid Configuration
– Suitable for intra-city traffic with frequent starts and stop
– Common electric traction system for a variety of power sources
• Downsized IC Engine-genset (Diesel/CNG hybrid electric buses)
• Overhead dc line (Trolley buses)• Fuelcells (Fuelcell buses)
– Fixed speed reduction possible – no gear-shifts, clutch operation
– Fuel economy more or less independent of driving conditions and driving habits
• Parallel Hybrid Configuration– Suitable for intra-city traffic with frequent starts
and stop– Smaller electric motor and controller rating– Easier adaptation on existing powertrain – Fuel economy varies with driving conditions and
driving habits

Passenger and disabled friendly
• Ease of entry & exit through wide entry doors and low step height
• Ramp access to wheelchairs
• Special area for wheel chair docking
• Kneeling feature to aid entry and exit
• Stop request switch on each pillar
Electronic fare collection
• Automatic Fare Collection System (AFCS) is an automated revenue collection system which facilitates purchase of pre-paid tickets and their subsequent use through electronic systems to permit access to or from the transport mode.
• AFCS reduces on-board ticketing, helps in easy accounting of revenue collection and generates rich information for MIS purposes. In addition, AFC reduces the need for ticket checking staff and helps prevent fraud.
Passenger Safety
• Introduction of ABS as an option.
• Introduction of Multiplexing Wiring System for electrical wiring related safety – Elimination of multiple wires, fuses & relays
TTiirree PPrreessssuurree MMoonniittoorriinngg SSyysstteemm
• Monitor tire pressure and alert driver via display and audible alarms when tire pressures reach varying levels
• Can also monitor temperatures and provide warnings when specified temperature thresholds are reached
Clutch boosters are used to reduce the force required to operate the clutch pedal and to permit sensitive and accurate actuation of the clutch in the vehicle.
The clutch booster has two ports, one for oil inlet and other for air inlet. Oil inlet port connects with the Master Cylinder operated by clutch pedal. The air inlet port takes air from the auxiliary reservoir.

New features
New Generation Technology Brakes
Definition:
NGT is recent updated version of CGT Brake in which ;• Foundation brake is better in Lining life, reduced Brake Noise, provision of Wear and
temperature monitoring sensors, High performance brake liner, etc.• Brake Actuation system is 9 bar with oil separator and 230 CC compressor for in un interrupted
supply of clean air.
New features
Lining Wear Sensor for Foundation brake Definition:
Wear Sensor is a device used to monitor the brake lining wear of S’cam brake system. It provides signal to display monitor mounted in the dashboard of the vehicle and alert the operator when the lining is worn out and due for replacement.
Advantages of using Wear Sensor:
• Prompts the driver to replace the worn out lining- Vehicle braking is effective all the times.
• Wear sensor provides proper warning and prevents Brake drum grooving by rivets exposed due to complete lining wear.
• Unscheduled lining change, break downs are eliminated.
New features
Low Noise and High lining Life Brake liner.
Definition:
New brake liner suitable for CGT and NGT brake for bus application.; This liner proven its usefulness in severe duty cycles where brake liner temperatures are up to 200 to 250 degree Celsius.
Advantages of using Masu brake lining.:
• Linear torque characteristics wrt to braking pressure @ low speed and low pressure; resulting in uniform torque. (Less Noise)
• In the Transfer Film Technology friction is produced by inter action of films rather than mechanical action between drum and lining which produces vibration. Therefore the reduction on brake Noise.
• This also reduces thermal effect on foundation brake and thus improves lining life. (Almost Double).
• Constant deceleration and stopping distance even when vehicle reaches to High speed up to 100kmh.
