Currently, diesel engine pistons are typically made of steel - aluminum was used previously, as it had better heat sink properties, but Metallurgy has improved steel enough to the point where it holds up fine now. The highest ring on current production diesel engines is at the top of the piston now - this was in response to emissions requirement. Gas engine pistons are flat at the top, as it is a spark which ignites the fuel/air mixture; diesel engine pistons often have the 'Mexican hat' at the top of the piston, as they ignite through compression.
A gas engine ignites gasoline in the piston chamber with a spark from a spark plug. The expanding gas then pushes the piston out and the motor moves forward. A diesel engine uses diesel fuel, different from gasoline, and the fuel is compressed by the piston until it ignites, sending the piston out. There are no spark plugs in a a diesel engine. Some diesel engines will have "glow plugs" which are used to initially start the engine but once started, compressing the fuel is the method of ignition.
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
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.
Because a gas turbine is more efficient. A piston engine is better for acceleration but that's about the only advantage.
Kerosene is fuel for a diesel engine. gas is fuel for spark engines.
No you can not use gas engine oil in diesel engine oil because processing of diesel engine is different from gas engine oil. If you use this then it damage your vehicles.
A piston is where the engines power comes from I work with internal gas combustion engines however i know a little about diesel aswell Inside the cylinder fuel is drawn in and the piston moves up compressing the fuel. it keeps compressing until the pressure (according to common gas laws) increaces the temperature and the fuel ignites, the piston is forced downward (power stroke) turning the crank which moves the engine forward and the exhaust escapes through a valve and the processes is repeated
It absolutely could. A diesel engine does not use spark plugs to fire the fuel mixture. It uses extremely high compression. Gas is much more flammable than diesel and will ignite at a much lower compression ratio. If you put gas in a diesel the gas will fire before the piston is actually at top dead center. So the piston is still on the up stroke but the fuel has ignited, effectively forcing it down. The first thing to go....other than maybe pistons, would be the rod bearings.
NO! Don't do it because, if you try to start it with regular unleaded gas in the diesel fuel tank, you're very likely to damage your engine!Gas ignites from sparks from spark plugs. Diesel is an oil and ignites from the high pressure produced by the piston in the cylinder. Therefore a diesel engine needs no spark plugs to produce the fire.For more information please see the answers to the Related Questions shown below.
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
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.
Rudolph Diesel invented the diesel engine which uses diesel gas.
