Diesel engines are generally more efficient than gas engines. A Diesel Pickup truck will normally get far more miles per gallon than a gas one and still have equal or greater power available. Plus diesel engines tend to last much longer than gas engines easily running well over 300k miles with little to no issue.

Which is rated better diesel or petrol engine?
Each engine is rated better for different things. A petrol engine generally has a higher horsepower than a diesel engine, so acceleration and speed is often better on a petrol engine. Diesel engines tend to rate better with torque, so they are better at pulling heavy loads, which is why diesel engines are used in trucks and locomotives.
Can diesel gives more average than petrol?
Yes, diesel engines traditionally get better fuel mileage than a gasoline engine.
What is the adventages and disadvantages of petrol engion?
first of all its engine. ADVANTAGES - petrol is cheaper than diesel so cheaper to run. petrol cars generally cost less than diesel (a few 1000). petrol engines are usually faster than diesel off the line and have a higher top speed than a diesel car with the same sized engine. DISADVANTAGES - petrol is less economical than diesel and also diesel cars are much better for over taking than petrol as it has more torque (pulling power)
Who is better gasoline engine or diesel engine?
diesel. Diesel engines tend to have better efficiency especially at less than full load. Gasoline/Petrol and LPG engines tend to have better power weight ratios.
What is the difference in bhp between petrol and diesel engines?
Both our internal combustion engines but the main difference is that a petrol engine uses spark plugs to ignite the fuel but a diesel engine has no spark plugs but instead uses compression to ignite the fuel. A diesel engine is also built much stronger than a gasoline/petrol engine. Diesel engines get better fuel mileage, last longer, and have much more torque or pulling power than a petrol engine. The only disadvantage to a diesel is the fact that it is more costly to build than a gasoline engine.
Is petrol engine or diesel engine better?
AnswerIt's more a question of being different than one being outright better than the other. Diesels have the possibility to give better fuel efficiency, but tend to run rougher for instance. And for the same engine size/weight, a diesel will have a lower peak power output.So, what's the "better" engine will depend on the engineering requirements and you preference.AnswerA petrol engine runs on petrol and a diesel engine runs on diesel- this is the basic difference between the two. But yes, jokes apart there are many more differences too. In a vehicle having a similar mass a diesel engine is more efficient most of the times than a spark-ignited petrol engine which results in the diesel having a lower fuel consumption and a cost effective solution for the consumer.
What is better a diesel or petrol engine?
It's more a question of "different", than "better". Petrol engines can have better power-to-weight ratios, while diesels are a little more efficient.
Which is more efficient a petrol engine or a diesel engine?
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
Why diesel gives more milage than petrol and petrol car costly than diesel?
Diesel engines are more efficient and do use less fuel, but they do not cost less than a petrol engine, they cost more. Diesel fuel also costs more. A diesel engine will however last longer.
Is the petrol engine is costly thab diesel engine?
No, diesel engines cost more to build than petrol engines. They are built much heavier.
Why diesel engine is more better than petrol engine?
because diesel engine has the maximum efficiency than petrol engine. also diesel engine can handle more load than petrol,as we can see in case in case of heavy vehicles. --- Fuel Savings result because the Air to Fuel ratio is MUCH more "lean" (more air) in a Diesel than in a gasoline/petrol engine. At idle, the optimal mixture for gasoline is 14.7 parts of AIR to one part FUEL. Compare that to a Diesel engine, where the ratio is 50:1, and you'll note a significant savings. --- Other Advantages: Diesel designed his engine to run on virtually any available fuel (e.g.; vegetable oil) for times of short supply of petrol/gasoline. The diesel engine has higher TORQUE, meaning that it can haul larger loads than a gas/petrol engine. There is no Ignition Circuit to fail on a diesel engine. The ignition is achieved by compression and a "glow plug" which remains heated between piston cycles. ---
Is the volumemetric efficiency of diesel engine more than a petrol engine?
Yes
