The fuel is ignited by compression and not by a spark plug. The compression of the cylinders is much higher than in a gas engine. The fuel must be compressed to the point at which it will ignite. This cause the noise you hear from a diesel engine.

My car starts in the morning with a very sharp noise. I turned off the key and took it out. But the engine kept shaking.?
GASOLINE ENGINE OR DIESEL?
What is the difference between a diesel engine and a petrol engine characteristic?
A diesel engine ignites it's fuel through compression and has no spark plugs. A gasoline engine has 1 or 2 spark plugs in each cylinder that fires at a set time and ignites the fuel. A diesel engine typically has much more torque than a gasoline engine and is designed to pull a heavy load. A gasoline engine will accelerate faster than a diesel but the diesel will have much more torque and be able to pull much heavier loads. A diesel engine will last much longer than a gasoline engine as it is built much heavier. Modern diesels are fairly quiet and make almost no more noise than a gas engine especially off idle.
Why are diesel engines loud?
Diesel engines detonate. Diesel has more potential energy than gasoline, instead of burning evenly, diesel explodes creating a knock or rattle noise.
The Pros of Diesel Engines?
Car engines come in two broad categories, both named after the type of fuel they consume: gasoline and diesel. In turn, the design of each engine is named after their inventors: Nikolaus Otto invented the Otto cycle for gasoline engines, and Rudolf Diesel invented the Diesel cycle for diesel engines. Diesel created his engine after learning about the engine created by Otto at the Polytechnic High School, the equivalent of an engineering college. Gasoline engines are less efficient than diesel, but diesel has a reputation for being dirtier than gasoline, so gasoline is the engine of choice for most domestic automobile manufacturers. Despite the fact that they are both internal combustion engines, the disadvantages of diesel has in the past far outweighed the advantages. Fortunately, improvements in design have made diesel more attractive, and diesel today is a serious alternative to the predominant gasoline engine. Major car makers like Mercedes-Benz incorporated diesel engines into their designs in the past, but today the diesel engine is starting to make credible inroads with other companies. The main advantage of a diesel engine is it's high fuel economy. The fuel economy of a diesel-powered truck or car is about twenty to thirty percent better than gasoline-powered vehicles. In times of high fuel prices, this can prove a big enough advantage to choose diesel by itself. Other advantages include less maintenance costs, due to the absence of spark plugs. The Diesel cycle uses the intense compression of fuel and air to ignite and combust the mixture. The reason this works is because of the high energy density of diesel fuel. The high energy density combined with the increased mechanical efficiency explains why diesel engines achieve such incredible fuel efficiency. Added advantages include improvements such as less noise, less soot and less cost. Today, the noise produced from a diesel engine and a gasoline engine are so close they are almost indistinguishable. Owners of diesel engines tend to fall in love and spread the word about how efficient and clean their cars are.
Does super unleaded gasoline clean the engine?
All automotive gasolines have engine cleaners in them. "Super" gasoline is only used when your engine "koncks" (Makes a tapping noise) when you stamp on the gas pedal, especially going uphill. If your car manual says to use "Regular" gasoline, do so. "Super" burns quicker to eliminate knocking, but has less available power in it. FYI, diesel fuel has more power in it than gasoline does.
What will happen if diesel engine is run on petrol?
The engine may suffer serious damage. Of course, it all depends on how much diesel remained in the tank before adding gasoline and how new the engine is. In 2007 or newer clean diesel engines, amy amount of gasoline will do damage to the sensitive emissions control components and system. In older engines with much less sophisticated and touchy emission systems, a lightly diluted (say 90% diesel & 10% gasoline) mix would probably pass through with little or no detriment. It may simply cause reduced engine power, perhaps a bit more noise, and possibly a warning from the emission sensors that detect something other than pure diesel exhaust. It is a high concentration of gasoline that spells real trouble. Burning straight gasoline or a highly diluted gas/diesel mix will almost certainly result in catastrophic damage to the engine. Diesels can burn a lot of things but gasoline is not one of them.
Why are diesel trains louder than electric trains?
Diesel trains are louder than electric trains because you the noise that the diesel engine makes, which is louder than the electric engine.
What is that knocking noise coming from the engine?
If its gasoline it would be a problem in your head causing the piston to slap against the cylinder walls. If its a diesel engine then the knocking is caused by the .001 to .002 second delay between the fuel injector closing and the compression/combustion of the fuel
Will diesel fuel hurt a Mazda 3 2005?
It won't cause permanent damage to the engine than carbon buildup, but it might damage the in-tank fuel pump, clog the catalyst, and ruin the oxygen sensor. But first, I will assume that what happened was that, by mistake, the car was filled with diesel in the tank at a gas station. Then, I will assume that there was still some gasoline left in the tank. That said, what will happen is that the remaining gasoline will mix with the recently-pumped diesel, will lower significantly the octane rate of the fuel available, causing a lot of noise, in the form of knocking and pinging to the engine, and the engine management system might shut it down eventually. So, if the amount of diesel was greater than the amount of gasoline, the engine will stop running very soon. On the other hand, If the the amount of gasoline was greater than the amount of diesel, the engine might be able to continue running, causing damage to the components mentioned above, and still making a lot of noise. The solution will be draining all the contaminated fuel from the tank and replace it with the highest octane fuel available, and take all the contaminated fuel from the system by blowing compressed air, from the front of car, on the engine side, to the tank, with the pipes disconnected from the tank. Then, you need to pay close attention to future the check engine light indications, adverse fuel economy and/or unusual smell of the exhaust. Damaged catalyst and sensors might not require immediate replacement, but will fail in the near future
Why don't you use 2 stroke diesel engine in our bikes?
if we use 2 stroke diesel engine in our bike then engine get more vibration & noise so it is not comfartable to the rider so it cant use in our bike
What is DDIS technology?
Diesel direct injection system is the latest technology in diesel engine. In this technology multi step injection is done due to this technology engine produce less noise & less vibration.
What is causing a tapping noise in a Detroit diesel 60 series engine?
Tapping in a diesel engine often means a valve lifter is beginning to fail. It can also mean that sub quality fuel is being used.
