HI, The main difference is that a diesel engine uses compression to ignite its fuel, and a gas engine is the same as a petrol, it uses a spark to ignite its fuel. Diesel engines are more fuel efficient than petrol or gas. For instance if a diesel used 10 liters per 100kms a petrol engine of the same size in the same car would use roughly 12 liters per 100kms and a gas engine 15 liters per 100kms. Diesel engines are more ruggedly built to withstand the shocks and forces produced by compression ignition and therefore will generally last longer. Gas though, is the cheapest fuel on the Australian market so it is the cheapest to run in fuel cost. Personally I'm a diesel mechanic so i would say diesels are better, but if your after short term savings on the fuel bill I would go for a gas engine
What else can I help you with?
What is the difference between unleaded gas and kerosene?
Kerosene is fuel for a diesel engine. gas is fuel for spark engines.
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.
What is difference between a diesel and petrol engine?
Basically diesel engines are much higher compression giving them more torque also the fuel is ignited by compression not a spark like in a gas engine
What is the difference between petrol and diesel car engines?
there are lots of differences. one no spark plugs. diesel fires by compression and heat gas or petrol requires a spark. the fuel delivery is diffrent to diesel is usally injected under a higher psi to areosol the fuel better. but diesel is more like fuel injection because the valves are diffrent
What is the difference between mazot gas and natural gas?
Mazot or mazout is a French word meaning fuel oil. Therefore, it is a fuel gas that is processed from liquid hydrocarbons taken from wells. Natural gas is generally any hydrocarbon gas that comes from a well and is mostly methane.
Is diesel a gas or an oil?
diesel is a fuel that has oil in it
Is diesel a solid liquid or gas?
diesel is a liquid fuel at the gas pumps.
What is the difference between a red and blue gas can?
Red fuel containers are for gasoline. Blue are usually for diesel fuel. Some water containers are also made blue and look sort of like gas cans, so check to make sure it is actually meant for fuel before filling it. Otherwise the plastic might turn out to be not fuel-resistant and melt.
Is diesel a gas?
Yeah diesel is a gas or they whouldnt let u put it in to ur gas tank. R u sttupid.actually diesel is a type of fuel used with engines that are made for diesel fuel. but yes it is a FUEL the same as Gasoline.Diesel is a liquid.
What gets better fuel mileage gas or Diesel?
diesel.
Does gas float on diesel?
Diesel fuel mixes with gasoline.
Difference between steam engine and diesel engine?
Steam engine: external combustion (the fuel is burnt in the boiler and the steam led through pipes etc to the power cylinder(s). Diesel (and petrol and gas): internal combustion - the fuel is burnt in the cylinder. Otherwise they are all Heat Engines.
