As the Engine capacity/size increases it is unavoidable that the rest of the engine has to increase in size to cope with the larger forces the larger engine capacity produces.
This has the unavoidable effect of increasing friction, and reducing Fuel Efficiency.
Hence a 4 liter engine will use more fuel than a 2 liter engine if all other things such as:
Technology, weight of vehicle, driving style, fuel type etc are the same.
Having a vehicle capable of 180MPH, that does 15MPG is regarded as "a problem" by some when the speed limit is 55MPH and a vehicle capable of 100MPH will do 60MPG.
**Cars with big engines are considered a problem because it uses more fuel and creates bigger emissions.
What else can I help you with?
Can you use a motor from a manual transmission in a car with an automatic transmission?
Most cars this is not a problem, the engines are identical.
What did Charles Rolls and and Frederick Royce produce?
Luxury cars, but later also big engines and powerplants.
Were there cars in the 1890's?
Yes, there were many early cars in the 1890's. Believe it or not, electric cars were big in for a couple decades! Steam powered cars were also available as well as the early gasoline engines.
Muscle car power vs compact car power?
The fact is that most muscle cars have big V8 engines that are built for raw power but the one problem is that muscle cars are heavy which import cars are not but the V8 can make up for it with most going over 400+ HP and there are not that many import cars that can match that, in the end pure power wins the race.
What engines are cars powered by?
Internal combustion gasoline or diesel engines power cars. Cars are also powered by electric motors.
Why can there be more hp out of small engines compared to big engines?
that isn't always true. however, smaller engines are made towards higher rpm's. and also rev up faster. larger engines are more for torque, and smaller engines are more compact and for lighter cars.
What cars have loud engines?
Basically, the muscle cars.
What is problem environment the difference between old cars and new cars?
Older cars are not so efficient and geneate more CO2 emissiong while new cars have more efficient engines and generates way less CO2 for the same horsepowers.
What do cars have in common?
engines
Why do motorcyclists rev their engines at stop lights?
For the same reason why muscle cars and sport cars rev their engines.
What cars have aluminum engines?
Some Volkswagens and Ferraris have aluminum engines
Inga was riding on a train that had 96 cars this particular train had one engine for every 24 cars how many engines did the train have?
If the train had 96 cars and one engine for every 24 cars, you would divide the total number of cars by the number of cars per engine to find the number of engines. So, 96 cars divided by 24 cars per engine equals 4 engines. Therefore, the train had 4 engines.
