Do diesel engines require spark plugs?
No diesel engines use the "heat of compression" to cause fuel to ignite not electrical ignition.
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.
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.
Why do diesel engines ignite even though they have no spark plugs to ignite this mixture?
Compression and heat. The fuel/air mixture is compressed to such a high level as to get hot enough to cause the mixture to self ignite. Gas engines require a spark to ignite the fuel. Gasoline engines have a compression ratio of 8:1 to 12:1. Diesel engines have a compression ratio of 14:1 to 25:1.
Is there any way to convert a diesel engine to gas?
Realistically it wouldn't be feasible to convert a diesel engine to gas. Diesel motors require much greater compression - enough that it could cause an explosion with a gas-configured motor. Plus, diesel doesn't use ignition or spark plugs, and the fuel pump/fuel ignition systems are completely incompatible.
What causes no spark on 1993 Chevy Lumina?
A BAD CRANK SENSOR WILL CAUSE NO SPARK AND NO PULSE SIGNAL TO FUEL INJECTORS a bad ignition module will cause no spark its located under the ignition coil trio pack
Can you use gasoline engine oil in a diesel engine?
No, absolutely not. Diesel engines run at a much higher compression than gasoline engines. A typical gasoline engine has a compression ration of 10:1 while the typical diesel compression ratio is 20:1 or higher. The diesel burns fuel through compression and the gasoline burns by ignition. You must use an oil with an API rating of C (Compression) in a diesel. Gasoline engines use API rating S (Spark). Use exactly the proper weight and API rating as listed in your owner's manual. Use a gasoline motor oil and you will destroy that diesel engine. -IMPROVED - I totally agree with Almostevil. I own a diesel and this is what I use. So, I didn't "improve" his answer but do back it up!
What sensor could cause no spark on a 1995 caprice?
No spark would usually be the ignition coil.
Is there a motor that can use diesel and regular gas?
even know the mechanism is pretty much the same a diesel fuel has a lower ignition temperature than gasoline, allowing combustion to occur simply by compressing the air/fuel mixture. Gasoline engines require a spark plug to ignite the fuel. Too much gasoline will not allow the engine to work efficiently and quite possibly not at all. Also, diesel engines use an injector pump to pressurize the diesel so it will form a fine mist when pushed through the injectors. These pumps require the lubrication of diesel to continue to work. Excess gasoline will cause failure in the injector pump and damage the injectors. this is why there are non dual fuel system engines
Why isn't your mini chopper getting spark?
Bad spark plugs can cause a mini chopper to not get a spark. Another common cause is a bad ignition switch.
What are symptoms of a bad ignition coil?
A bad ignition coil will cause your engine not to have any spark. Without any spark the engine cannot start or run.
How do diesel powered engines work?
Diesel engines work by using compression to cause an explosion which releases a surge of power. The engine compresses diesel fuel and oxygen in a cylinder until the fuel heats up and explodes.
