Design of Lean Burn Engine for Scooters

International Journal of Recent Technology and Engineering (IJRTE), 2020
Internal combustion engine powered vehicles are widely used all around the world for mobility. Scooter is the most commonly used two-wheeler by people of all age groups due to its easy handling and riding comfort. Due to gearless transmission, the mileage of scooter is low compared to gear transmission bikes. Nowadays increase in petrol price makes the
