what is the difference between a tubocharger and a supercharger in a diesel engine?
337998
From wikipedia.com:\n\nA supercharger (also known as a blower) is an air compressor used to compress air into the cylinders of an internal combustion engine. The additional mass of oxygen-containing air that is forced into the cylinders improves the volumetric efficiency of the engine which allows the engine to burn more fuel and makes it more powerful. A supercharger can be powered mechanically by belt-, gear- or chain-drive from the engine's crankshaft. It can also be powered by a gas turbine . When a centrifugal type compressor section is mated to a gas turbine drive it is then referred to as a turbo-supercharger, commonly called a turbocharger . Positive displacement Superchargers may absorb as much as a third of the total crankshaft power of the engine, and in many applications are less efficient than turbochargers. In applications where engine response and power is more important than any other consideration, such as top-fuel dragsters and vehicles used in tractor pulling competitions, positive displacement superchargers are extremely common.

Smaller cog on the engine, larger on wheel or Axel.\nThat combination will give you more top end but a \nslower bottom end, meaning that it will take more\ntime to get to top speed. A larger cog on engine and\na smaller cog on wheel or axel will give you a higher \nbottom end but you won't get a faster top end.

The power comparison is about 8,000 hp(top fuel) to about 60,000hp(boeing) The fuel consumption comparison is apples to oranges. The boeing uses heavy jet propellant basically diesel fuel while the top fuel uses alchohol and nitro methane. it would be like comparing drinking water versus eggnog... What's the point?

Diesel fuel is less combustible than petrol so the engine which burns it is constructed differently. The diesel engine must be built heavier due to the high compression required. The diesel engine needs an injection pump to operate adding more bulk to what already needs to be a heavily constructed engine. A gasoline engine on the other hand, can be built very small and lightweight.\nI suppose though if someone were intent on designing a diesel scooter it could be done.

Define high pressure. Define high capacity.\n\nAre these reciprocating or centrifugal compressors?

Turbo is a good way to increase your car's power. Also, a bigger intercooler as well as new piping kit will help moter breath better. A new air filter will give you some extra power. A good exhaust and a new ECU program will help you a lot. After these your power must be 500+ PS, believe it or not. I have seen M3 over 1000 PS.

they are a four stroke just like gas engines but gas engines are spark ignition and diesel engines are compression ignition, that is whey there is no spark plugs the heat from the piston compressing the air and fuel mixture gets to a point of explosion and boom down goes the piston and over and over it goes and away you go (Intake compression, power, exhaust)

petrol or gas engine is internal combustion engine that uses ignition spark to ingnite the fuel air mixture. a diesel engine compresses the fuel air to ignite the mixture. petrol.....spark plugs & diesel....no spark plugs

Ethanol is bad and creates many nasty acids that wear away the journal bearing babbits, etc.  Many materials cannot stand up to the increase acidity present when burning higher percentages of ethanol. (Boy i hope i don't mean methanol instead of ethanol.  You might want to double check me there!)\n\nCNG can ONLY be used on SUPERCHARGED diesel engines.  To date, there are no SUPERCHARGED automotive diesel engines made.  The only way to get CNG into a diesel engine is to use very large superchargers which run mechanically off the crankshaft to ensure enough air-fuel mixture gets into the engine.  See Waukesha for stationary CNG products.  Traditionally, many diesel/CNG power plants run on CNG most of the time to save $.  \n\nCNG is GREAT for normally aspirated automotive spark-ignition engines.  It may produce less peak power, but the cylinder wear is REDUCED, oil contamination REDUCED--the engine runs SO MUCH CLEANER it is unbelievable.  Combustion chambers remain spotless and spark plugs stay clean.  CNG evaporators need a heat source, so in cold climates you may have to have a preheater.\n\nYou may be able to increase compression ratio when building up an automotive conversion--but don't overdo it.  I know plenty of CNG trucks that end up blowing a head gasket because people have a lead foot.  You could probably run a 9.0.  The best engines to use are V-8 carbureted truck engines.  \n\nTotal fleets of frozen food delivery trucks have been converted to CNG--but none has a diesel engine--they are all gasoline type engines.  So they do use them in trucks.  \n\nCNG will run out fast in your automotive application.  CNG must be stored in a gas phase, which means by the cubic foot.  It is not practical usually to build CNG storage into a car, and check with your Dept. of Transportation on explosion hazards--it may be illegal in some cases to carry so much cubic feet of explosive gas on a car or in a non-rated tank.  The heating value, i.e. energy per cubic foot of fuel is far less than gasoline, and less than propane. \n\nThe most practical conversions for cars are propane kits.  They are very simple: pressure regulator, evaporator, and some kind of throttle linkage.  You will get a few more miles per bottle of propane than CNG.  Both propane and CNG keep engines spotlessly clean.  Be sure to start with a clean engine and be sure that the valves have valve seats in the heads.  Exhaust gases can run the valves a bit hotter than when burning gasoline because of unburnt hydrocarbons in the exhaust--if your air-fuel ratio is right, you will never have that problem with CNG or LPG.

Steam turbines have several controlled nozzles which connect to the superheated steam source from the boiler and superheater.  The number of nozzles and steam flow rate through the nozzles can control the power output of the turbine.  The momentum of the steam gas hitting the turbine (in stages) as it expands spins the turbine creating shaft power.\n\nOne type of gas turbine is the exhaust side of a turbocharger.  Hot exhaust gas under pressure is pumped by the engine into the the outer ring of the turbine.  The gas is still expanding, and spins the turbine providing shaft power to drive the air compressor side.  \n\nThe type of gas turbine common to power plants and airplanes has a compressor section, combustion chamber, and expansion section.  The expansion and compression turbine sections have moving vanes and stationary vanes to direct the gases and extract the most work possible from the setup.  Atmospheric air is compressed by the compressor and fed at elevated pressure to the combustion chamber where fuel is injected and an ingnition source keeps the flame lit.  The exhaust spins the expansion section and exits through the rear of the engine.

You should size the turbos based on your horsepower goal:\n\nA turbo helps support about 1 horsepower per 1.345 cfm airflow (that the turbo is rated at). Take the cfm rating of the turbo you are considering and multiply by two (to get the total cfm provided by the two turbos).\n\n\n----\n\nWhat I referred to was the cfm ratings of the turbos themselves. Those are usually specified by the turbo manufacturer in the form of a compressor map. The 1.345 figure I gave is the most commonly quoted estimated. For example, if you wanted a 250hp car, you would need one or more turbos rated a combined 336 cfm.\n\nAnother factor is making sure you have enough exhaust flow to spool the turbos quickly. In other words, don't oversize the turbos or the turbo response will not happen until a high rpm, thus reducing drivability somewhat.

boost controler , hard pipe kit , greddy blow off vale, bigger inter cooler but not to big you will have boost drop with a bigger inter cooler , kn air filter , 3 inch exhuast all the way back , change from a twin turbo to on big turbo like a super 25g is my fav , standalone ems , after all this you will need a new clutch to like a stage3 act is great ,

well you can go force induction (turbo, supercharger)\nneed basics, intake, headers, exhaust.\nthen you can go cams, camgears, injectors, larger throttle body, pully system, hondata chipped ECU.\nNote, after you put anything on your S2000. you need to get your VAFC calibrated.  specs will change since your adding after market parts and its set for stock

I'm not positive on this but I believe to what your refering to is the degree of seperation from when exhaust valve closes to when intake opens.\nBig blocks and performance cams tend to have a longer seperation to deal with higher RPM's with out valve overlap which would decrease top end.

You do not need the supercharger to run this engine...   BUT the engine now has a dead supercharger sitting on top, your airflow and compression are completely off..   Go on e-bay or to a  local junk yard and get one.  3.8 Eaton superchargers are a dime a dozen...  It's not that hard to replace either.

A supercharger is powered mechanically by belt- gear- or chain-drive from the engine's crankshaft.

Superchargers may absorb as much as a third of the total crankshaft power of the engine, and in many applications are less efficient than turbochargers. In applications where a massive amount of power is more important than any other consideration, such as top-fuel dragsters and vehicles used in tractor pulling competitions, superchargers are extremely common.
