Why diesel engine has more efficiency than petrol engine?
Diesel is a more combustible fuel than petrol, therefore less fuel is required to generate the same power as petrol. This also means that spark plugs aren't required, like in a petrol engine, since the diesel will ignite off engine compression alone. This also makes the engine arguably more reliable since there are less parts, and less things to go wrong.
What is the weight difference between a diesel engine and a gas engine?
A diesel engine is heavier than a petrol engine because some parts in a diesel engine are made from cast iron such as cylinder sleeves etc. The weight difference is usually between 10-20kgs.
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. ---

WHAT ARE THE BASIC PARTS OF PETROL ENGINE? HOW DOES PETROL ENGINE WORKS?
Why lubricating oil quantity differs in petrol and diesel engines?
Diesel engines have closer/smaller tolerances between their parts and the forces & pressures within a diesel engine are much greater than a conventional petrol internal combustion engine. This requires a better quality oil to provide better lubrication under higher pressures & greater friction conditions in the diesel engine.
What damage can petrol do to a diesel engine?
It can make the engine seize up, the mechanic parts and components are made to work with the right type of fuel for the engine. Basically, if you put petrol into a diesel engine, it would run for about 10 minutes then die. Then you would need a new engine. Diesel fuel is oily and provides lubrication for the pumps and injectors. Petrol does not provide the lubrication, so the pumps and injectors will be damaged. It is unlikely that the engine will run at all if all petrol is used. Diesels are compression ignition engines. The fuel ignites as soon as it is injected into hot air. petrol needs a spark.
Does temperature make petrol evaporate?
In a petrol engine, the petrol is evaporated before it is burnt, this means it burns better, increasing engine efficiency.
How do you distinguish between a petrol engine and diesel engine?
A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition. Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.
Is a diesel engine compatible with a Petrol Car?
No, diesels rely on compression to ignite the air fuel mix, therefore parts are heavier and more expensive Petrol engines rely on spark ignition. All the electrics will have major differences.
What happens if petrol is put in a diesel car?
There are a few different views on what happens if petrol is put into a diesel car, ranging from "this is horrible and will ruin the engine" through "if diesel is put in a petrol engine, it will run but misfire" and "it does depend on the make and model of the car" to, most commonly "petrol will kill a diesel engine; don't start it, have it towed to your mechanic, and have him drain the tank and the fuel lines." Modern diesel engines use the diesel fuel as lubricant for the high pressure pump. The engine itself will run on petrol but it is only a short period of time before the pump is damaged. Petrol is a poor lubricant in comparison to diesel fuel. Generally when this happens the entire fuel system needs to be flushed to remove the petrol and the metal debris from the damaged high pressure pump, then the pump and any other damaged components need to be changed. Additional damage can also come from pre-detonation; diesel engines run far higher compression ratios than petrol engines, this is due to, in a simplified manner, diesel being less volatile than petrol. The effect is that the petrol/air mix may detonate 'early' i.e as the piston is rising during the compression phase, before the normal ignition and combustion phase. This essentially forces the piston to go back down early and attempts to turn the engine over in reverse. The huge additional forces generated can and almost certainly will be catastrophic for most internal components. Given the huge potential for damage to your car's engine, it might be annoying but it makes sense to have the car towed or transported to a garage, to have the tank drained and then for the system to be checked through by a mechanic.
Why desiel engines will give more milage when compared to petrol enginess?
They are simply built much tougher. Diesel engine have a compression ratio that is much higher than any petrol engine. As such the internal parts must be built stronger to handle the higher compression. Also the diesel fuel itself provides some lubrication. These factors provide for a much longer life.
