diesel engine generates too much air pollution than petrol is not environmental friendly.

Diesel has low ignition temperature w.r.t. gasoline/ petrol and it is denser as well. In diesel cycle the compression ratio is 16 to 22:1 which is good enough to give a homogeneous combustion in very short time of piston movement. Adding spark to diesel will cause premature, inhomogeneous combustion.

diesel is denser then petrol more over, both engines works on diff cycles. spark plug will not prove to be a key to homogenous cumbustion in diesel and fuel will ignite early
