Fuel and Engines

what is sales and purchase cut off

EFI Advantages..... assuming new engine..... more fuel efficient, easier to keep in tune, less maintanence. Dissadvantages.... costly to repair, harder to diagnose problems without electronic diagnosis downloading equipment, more sensors that can fail. Simple ignition systems with simple fuel systems work well but require regular "tune ups" and are not as efficient. Cars from the 1960's had simple systems and as electronics became cheaper and with the costs of fuel increasing and the need to clean up com,bustion engine emissions, the manufacturers went the way of fuel management systems to improve efficiency (mainly due to government mandates)

EFI...electronic fuel injection....there a a few different names for the various systems, but this is the simple basic way to describe both. Fuel be it either gasoline or diesel is pumped from the fuel tank through filters to get out any impurities into a manifold under pressures ranging from 20lb for a gas engine to 3000lb for a diesel engine. at each cylinder (on modern fuel injection systems) there is a fuel injector which opens electrically at the exact time or mechanically, to allow the pressurised fuel to squirt into the cylinder......like a spray can does.....its contents are under high pressure and when you push the button the contents are released under pressure.

stock -iron heads, etc.- 670lbs.

Yes

yes

yes, it can. its possible to damage piston rings and other parts of your engine. This is more likely to happen if the nitrous system is not used correctly. One way for nitrous to harm the engine is if you create a "lean condition" in which there is not enough fuel being sent to the combustion chamber. As nitrous is injected, additional fuel is required.

You can use a fuel tank additive called "Heet." Basically, Heet is a type of alcohol which mixes with the water in your tank and allows your engine to burn it.

Depnending on the amount of water the tank could need removed or drained.

Well, you have to figure out.

very very very efficient. get a Ferrari It depends largely in what way you mean efficient. An engine can be efficient in many different ways, but usually not all ways at the same time. For instance; the engine of a Formula 1 car is incredibly powerful but is designed to last only one race and has to be rebuilt every time, not to mention it drinks fuel like it's going out of fashion! If you put this engine in your family saloon it wouldn't be your idea of efficient, but it does the job where the race-driver is concerned! Most modern cars have electronic engine-management systems which regulate things like fuel / air ratios, spark timing and valve clearances. These change the characteristics of an engine to be more or less powerfull given certain conditions. The engines these management systems control have the potential to be very high performance machines, and are so heavily over-engineered that the management system is actually calibrated to stunt the engine's final output rather than increase it! It is the management system of any engine that determines how efficient it is in any way, be that fuel economy, power-weight ratio, top speed, etc. The engine itself can be made no more efficient in terms of mechanical innovation. A management system, by the way, doesn't have to be electronic. A Carburettor is also a type of management system, it is just controlled differently. As a rule, naturally aspirated engines are less efficient in many respects to those controlled by "black boxes" The only real way to improve the efficiency of an engine other than by changing the way it is controlled is to change the fuel you put in it. Hydrogen fuel for instance is over 8 times more combustible than petrol and produces a far greater output for less input. There is also no waste product, other than water! THAT'S efficient! (Believe it or not most of the petrol you put in your car isn't used to create the pops & bangs that make it go, but acts as a coolant inside the cylinder!) _____________________________________________________ just under 100% efficient >>>>>>>>>>>> It's the best there is. ---- Hydrogen engine is the most efficient engine known to man, because hydrogen has very high combustion rate, it is the most abundant element in the universe, and when burned in a vehicle the only byproduct is water.

in 1970-1973 ford introduced the 4 barral carb 351 Cleveland with a horsepower rating of 300

68 hp.

Water, If water gets into the oil, usually as the result of a broken head gasket or a cracked head, it will form an oil water emulsion. Stop the motor immediately as this will damage the rest of the engine.

define engine cc size 246cm

4 stroke oil

no, the crankshaft has to be removed to get to the bearings therefor removing the pullies, fan belts, timing belt, sump, main studs etc etc,

if you are considering upgrading internal bearings i recommend doing a total rebuild, eg - arp head studs and main studs, eagle rods, forged or billet items inc pistons, rods, bolts, bearings, boring if needed and nitriting the crank along with the block for strengthening,

no point in pulling a engine down just to change 2 bearings, may as well spend the time wisey and upgrade everything else at the same time.

more money yes, but a small price to pay for 4 times the power and 10 times the strength and reliability :-)

Sounds like a wheel bearing.

Thare are a number of things that could cause compression loss, Like bad valve, rings, or the head gasket.

Steam engine advantages

Any suitable form of energy can be used to make steam

Not affected much by high altitudes

Water can be re-used

Steam engine disadvantages

Has low efficiency, around 30%

Are expensive to buy and run

Give off a lot of pollution

Take time to start

Dangerous to use because of high pressure of steam

Only 30% of the steam is used

Lots of energy is needed to make the steam

The litres of the engine.

Say, for instance, a 350 Chev, it's a 5.7lt V8

So therefore, it is a 5700cc (approx)

These are almost never exact, but rounded to the closest whole number It is an actual measurement of the amount of air that is displaced as the epistons move up and down. Say on a 1 cylinder engine the piston dirplaces 1 liter of air as it moves from bottom to top, that would be a 1000 cc (cubic centimeter) engine.

Valve clearance

The crankcase is full of gasoline. The reason for this is because of a problem with the needle in the carburetor. It allows gasoline to continue flowing into the combustion chamber even when the engine isn't running. An easy fix for this is to install a fuel shutoff valve in the fuel line close to the carburetor.
