Petrol Vs Diesel Engines – Which Is Better and Why? Part II

It is a known fact that diesel’s best selling point is its efficiency. And while petrol hybrid cars are very efficient, they still can’t match the fuel economy of diesel hybrids. The scepticism that however still remains attached to diesel-powered cars is that they are slow, but with the introduction of the turbocharger, engineers are proud to say that that is no longer a problem.

Petrol Vs Diesel Engines – Which Is Better and Why? Part I

After covering an article on the volatility of petrol and how fuelling at different times of the day might cause you to receive less value for your money, I would like to clarify that the same does not happen to diesel because it is heavier and less volatile. Also, while petrol burns easily and thus produces more power and faster propulsion, diesel burns slower – actually it does not even burn at all. Not that petrol burns either: it is the vapour that burns, but when it comes to diesel it will not vaporize easily and even when it does the vapour still will not catch fire. Combustion occurs in a diesel engine only when the diesel is injected into hot compressed air, and the energy output in this case is more of toque rather than power. Yes – torque is the ‘might’ to move a mass of load while power, better off described as horsepower, is the force that moves a car from one point to another, fast.
