STARTING & DRIVING — Driving <strong>Tata</strong> <strong>Indigo</strong> Diesel / Petrol Cars<br />

DIESEL & PETROL ENGINE :<br />

The combustion systems of the petrol engine & diesel engine<br />

are totally different. While the former makes use of the spark<br />

ignition, the latter uses compression ignition type. Due to the<br />

difference in compression ratios, cylinder pressure and<br />

combustion cycle the performance characteristics of both the<br />

engines differ greatly, even if the final power out put is the same.<br />

Therefore, if the diesel car is driven in the same fashion as the<br />

petrol car the response of the car will be entirely different for<br />

equal capacity engines.<br />
