How to reduce the fuel consumption of your car?
However, the average car speed is a useful indicator of fuel consumption. So, the next time that you will have to drive for a long distance try to keep your instantaneous car speed within the range 55 – 80 km/h as much as possible, in order to minimize the fuel consumption of your car.
What is the fuel consumption of a car?
0 – 30 km/h (0 – 18.64 mph): For velocities below 30 km/h the fuel consumption is quite high (above 8 l/100km – 29.34 mpg). Unfortunately this speed range is typical for cars circulating in a city – urban environment. Cars are subjected to a continuous start and stop motion due to junctions and traffic lights.
What is the fuel consumption of a car at 80 mph?
55 – 80 km/h (34.18 – 49.71 mph): For the particular vehicle, this is the optimum velocity range that minimizes the fuel consumption (around 6 l/100 km – 39.15 mpg). This range corresponds to rural or even highway driving conditions. Fuel consumption is almost steady in this range.
Why are petrol engines so inefficient?
Diesel is more combustible than petrol, therefore less fuel is required to generate the same amount of power. Secondly, petrol doesn’t undergo complete combustion and hence there is a small wastage of fuel. This is why diesel engines are more efficient than petrol engines.
Why are combustion engines inefficient?
While even a short explanation of why combustion engines necessarily require a somewhat lengthy explanation of thermodynamics, a Twitter feed length explanation is easy to understand: the difference in temperature between fuel combustion, the engine, and the air outside the engine determines thermal efficiency — i.e. combustion engine inefficiency.
Why do diesel engines have a higher thermal efficiency than gasoline engines?
According to Popular Mechanics, the reason diesel engines have a higher thermal efficiency than gasoline engines is that of two factors: compression ratios and lean-burn combustion.
Are gasoline-powered vehicles more inefficient?
And, gasoline-powered vehicles are even more inefficient, considerably more inefficient.
How does the engine lose energy?
In gasoline-powered vehicles, most of the fuel’s energy is lost in the engine, primarily as heat. Smaller amounts of energy are lost through engine friction, pumping air into and out of the engine, and combustion inefficiency. Advanced technologies such as variable valve timing and lift (VVT&L),…
What engine is more fuel efficient?
Diesel engines
Diesel engines are typically much more fuel-efficient than gas engines, even those with very high compression ratios. Diesel fuel is also more energy-dense than gasoline, meaning more energy per gallon. As a result, it’s not uncommon for a diesel-powered car to get 50 mpg or higher.

Is a bigger liter engine faster?
As a larger engine is usually able to burn more fuel and produce more power than a smaller one, a car with a larger, more powerful engine is likely to be able to accelerate faster and tow heavier loads than a car with a smaller engine can manage.
Is a bigger engine better?
As a larger engine is usually able to burn more fuel and produce more power than a smaller one, a car with a larger, more powerful engine is likely to be able to accelerate faster and tow heavier loads than a car with a smaller engine can manage. This rule of thumb is less accurate today than in the past.
Is a 1.0 litre engine better?
Today, a car fitted with a 1.0-litre engine can be just as powerful as an older car with an engine twice the size, but you’ll benefit from lower fuel consumption and decreased emissions from the exhaust, which should also keep your car tax costs cheaper. What does engine size mean?
How do you know if a car has a bigger engine?
Traditionally, a car with a bigger engine would generate more power than a car with a smaller engine. However, some modern cars have turbocharged engines, which allows them to be more powerful than they used to be. The amount of power an engine produces can be established by looking at the horsepower, also referred to as bhp.
Does the size of the engine mean how powerful it is?
The size of the engine doesn’t always indicate how powerful it is. Cars featuring ‘turbocharged’ engines can benefit from increased power and fuel efficiency without needing a higher engine cc. This will often allow them to match a higher cc car that does not have a turbocharged engine.

One of the first German V8 engines was the 1928–1945 Argus As 10 aircraft engine. This engine was air-cooled, used an ‘inverted V’ design and was used in several training, reconnaissance and communications airplanes. From 1933 to 1940, the Horch 830 luxury cars were powered by V8 engines (sold alongside Horch’s larger straight-eight engines).
What type of crankshaft did a V8 use?
Most early V8 road car engines also used a flat-plane crankshaft, since this was simpler to design and build than a cross-plane crankshaft. Early flat-plane V8 engines included the 1910 De Dion-Bouton engine, the 1915 Peerless engine, and the 1915 Cadillac engine.
