Most gasoline engines are 8:1 - 10:1 compression, while a diesel engine requires closer to 18:1 - 20:1 to achieve the temperature required to ignite the fuel. Simply put an electronic ignition system is less complicated and more cost effective to mass produce. Especially taking into account the emissions requirements for todays "clean" diesels.
Gasoline is not ignited using compression ignition for two reasons. First of all, an electronic ignition is simpler and does not require heaver engine parts to increase compression. Secondly gasoline has a much lower flash point than diesel which makes it more volatile and dangerous. As a result, if you compress then ignite it the fuel will burn at a hotter and less controllable rate. If gasoline burns at too hot a temperature it forms Nox gas - "Oxides of Nitrogen" which is a major contributing factor to ozone damage and the greenhouse effect.

What type of engine uses compression ignition as it has no spark plugs?
a diesel engine uses compression and has no need of spark plugs
A compression-ignition engine uses?
The heat from compression is so high that the fuel will auto-ignite when injected.
Can you use petrol instead of kerosene in a kerosene run generator?
No, the petrol has a higher ignition flash point than that of kerosene. It would be like using petrol in a diesel engine. The engine would run extremely hot and the engine could be destroyed. As diesel uses compression to burn the fuel petrol needs a spark. The petrol under higher compression will pre ignite and cause detonation in the piston cylinders. This could destroy the pistons, cylinder walls or the cylinder head of the engine.
Can you make a diesel engine which works on the basic principle of petrol engine or you can say it uses diesel as a fuel but works on the principle of petrol engine?
No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.
Main advantages and disadvantages between compression ignition and spark ignition engines?
A spark ignition engine is a gasoline engine. A compression ignition is a diesel engine.basic difference between compression and spark ignition engine is ,compression ignition is a diesel engine. spark ignition is a gasoline engine.diesel engines compress the fuel to a point where the fuel explodes, thus giving ignitiongasoline does not compress to explosion, therefore it needs need a spark to ignite the fuelspark ign. is gasoline. comp. ign. is diesel.A compression ignition engine is typically a diesel. It compresses air so much that the heat from the compression is enough to cause the fuel to ignited once injected. A spark ignition engine is your average gasoline-burning car engine. It uses a spark plug to ignite the air/fuel mixture instead of relying on compretssion ignition.A compression ignition engine uses very high compression of the air to heat it self up and the fuel is injected into the cylinder which self ignites (a diesel engine is a compression ignition engine).A spark ignition engine uses a lower compression ratio and requires the use of a spark to ignite the fuel (a petrol engine is a spark ignition engine).Because the oils used for a diesel have a higher calorific value, they have a better fuel economy, They also do not need extra energy usage to keep the engine running, unlike the energy that is lost to power the spark plugs from the generator/alternator which is taken from the useful energy produced by the engine.
What are the defferences between dessel and petrol engine?
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
Why diesel engine given name diesel?
This comes after the name of Rudolf Diesel who succeeded to build his well-known high-compression prototype engine in 1897. Rudolf Diesel was credited with this innovation.The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture.
What will happen if diesel filled in petrol engine?
the engine will not run because of three reasons. 1. Diesel uses more compression than the petrol engine does 2. the diesel engines fuel to air mixture is 1:1 and petrol isn't 3. diesel engines use straight compression or glow plugs instead of spark plugs
What engine uses a spark plug to ignite a compressed air-gas mixture?
A spark ignition engine, like your average gasoline/petrol burning car engine.
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.
What is meant by cetane number?
A cetane number is a rating given to diesel fuels. It is a rating of how fast the diesel fuel ignites under compression. In diesel engines, there are no spark plugs and the engine uses compression (pressure) to cause ignition.
Difference between the events of four stroke petrol engine and that of a diesel engine?
Diesel engines are still 4-stroke (unless and early Detroit engine which were 2-stroke) only real difference between gas and diesel is fuel delivery and ignition.diesel uses high compression,fuel atomization and heat to fire cylinder,where gas engines need a ignition source.hope info was helpfull.
