What is the financial outlay associated with traveling from Exeter to Three Rivers by car?

The journey, powered by petrol, incurs a cost of £30.9. In this computational scenario, the price of petrol is assumed to be 143 pence per liter, and the car's fuel efficiency stands at 37.5 miles per gallon.

For individuals contemplating carpooling arrangements, the expenditure per traveler diminishes as the number of passengers increases. With two passengers, the cost per person amounts to £15.45 (£30.9/2). For a trio of passengers, the cost per person reduces to £10.3 (£30.9/3), and for a quartet of passengers, it further decreases to £7.73 (£30.9/4).

To provide further elucidation on the calculation process, let us dissect how the final figure is derived:

Initially, the requisite fuel quantity is determined by dividing the distance traveled by the car's fuel consumption rate. For a journey spanning 178.04 miles, this computation entails multiplying 178.04 miles by 4.54609 (liters per gallon) and subsequently dividing by the car's fuel efficiency of 37.5 mpg, resulting in a requirement of 21.6 liters of fuel.

Subsequently, the fuel expenditure is computed by multiplying the amount of fuel required by the price per liter. Given a consumption of 21.6 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £30.9.

In summation, the total fuel expenditure for the trip from Exeter to Three Rivers stands at £30.9.

Diesel cost from Exeter to Three Rivers.

The trip with diesel fuel costs 19.5 £ (151p/lt, 62.7 mpg).
For 2 passengers: 9.75 £ (19.5/2) /p.
For 3 passengers: 6.5 £ (19.5/3) /p.
For 4 passengers: 4.88 £ (19.5/4) /p.

When comparing diesel fuel and petrol (gasoline) fuel in terms of octane rating, there's a significant distinction:

  1. Petrol:

    • Petrol typically has an octane rating ranging from 87 to 95 in most markets.

    • Octane rating measures the fuel's resistance to premature detonation or knocking in spark-ignition engines.

    • Higher octane ratings are crucial for high-performance petrol engines with higher compression ratios or turbocharging, as they help prevent engine knocking and allow for more efficient combustion.

  2. Diesel Fuel:

    • Diesel fuel doesn't have an octane rating in the same sense as petrol because it's not used in spark-ignition engines.

    • Diesel engines rely on compression ignition rather than spark ignition, meaning the fuel-air mixture ignites spontaneously due to high pressure and temperature.

    • Therefore, diesel fuel is designed to ignite under the high compression conditions found in diesel engines, and its properties are optimized for this type of combustion rather than for octane rating.

In essence, while petrol relies on octane rating to ensure proper combustion in spark-ignition engines, diesel fuel is formulated to ignite under the high-pressure conditions of compression ignition in diesel engines, rendering octane rating irrelevant for diesel fuel.
