Hindustan Times. The Delhi Cabinet is mandating that all two-stroke three wheelers—regardless of fuel—convert to four stroke engines in an effort to reduce pollution in the city.
The government will provider a Rs 6000 (US$128) subsidy to three-wheelers that had already converted from diesel to CNG to change to four stroke. There are some 55,000 three-wheelers running on CNG in the capital, of which around 15,000 are two-stroke vehicles.
The total cost of conversion to four-stroke engines is estimated to be around Rs 15,000 (US$322) and manufacturers have agreed to give a six percent concession to the owners of three-wheelers.
