Combustion Engines

The C6 -3 is twice as strong as the B6-4 but runs for a shorter time. It will propel a bigger rocket. I use C6 on rockets about 30-33 inches long, 1 inch diam.

Both types go through four phases: intake, compression, expansion and exhaust.

A 4-stroke needs two turns of the crankshaft to do this while a 2-stroke can do it in one turn of the crank.

And since it's only the expansion phase that makes power, being able to make power at every turn as opposed to every 2nd turn means a 2-stroke can make more power for the same size engine, or the same amount of power from a smaller engine.

The cost of this is that they tend to pollute more, and have less torque at low rpms.

well we need more info on your problem to be able to give you a fairly good answer. is it a tapping sound,knocking sound. where does the sound comes from top or bottom of engine. just listen to it and try to determine where you hear that sound the most. trust me it may be nothing expensive.

As the previous user suggested we need more info. A source of noise can be the combustion itself. The phenomenon sometimes responsible for noise inside engine is called combustion instability. This phenomena is caused by coupling between the acoustics (caused by the injection system, fluid flow etc) and the combustion itself. When this two couple and the excess energy can't be dissipated the perturbations inside the combustion chamber grow and the entire combustion process becomes unstable. The engine becomes very noisy and you can see a lot of vibrations. On a side note, combustion instability is a phenomena very important in rocket engines. That's actually the reason why USA won the space race to the moon against Russia. Russia was not capable to solve the stability of combustion in large engines as US did.

347 stroker is a 302, bored .030 over with a .400" long crank.

302= 4 x 3 inch

347= 4.03 x 3.4inch

the check engine light comes on for many reason or many parts usally emmision related.

yes both the 8 valve and 16 valve engines are interterence engines

Some heat from the combustion chamber goes out in the exhaust, but some gets conducted from the cylinder walls into the water jacket (liquid cooling). In an air cooled engine, heat is conducted into the fins and ultimately convected and radiated to the environment. If that did not happen, the engine would quickly overheat. That could cause it to sieze, or the fuel could preignite, basically throwing the ignition timing way, way off and the engine would stop.

To provide an accurate reading of the gas in your tank, the dash gauge relies on a stable power supply voltage and a relatively slow changing linear variable voltage proportional to the liquid level in the tank. Problems with either will result in misleading readings. Because the power supply in a car will vary between about 12.4volts and 14.5 volts it is usually not stable enough to supply the gauge. Instead the instrument gauges (gas, temperature, oil) receive their voltage supply from a stabiliser unit (generally mounted at the back of the instrument cluster). If this unit develops problems one or more and sometimes all guages will behave erratically. The gauge receives a voltage signal proportional to the tank liquid level from a sending unit (sensor) located in the tank itself. To test.....locate the supply wire from the sensor to the gauge. Ground (earth)this wire temporarily. Switch the ignition key on. The dash guage should indicate a full tank. If it does then the problem is with the tank sensor. If the gauge does not indicate 'full' then the problem lies with the guage end of things and not the tank sensor. If all other dash gauges are behaving normally the problem is most likely the fuel guage itself. If any other guage is reading erratically in addition to the fuel gauge the problem is most likely the voltage stabiliser, but don't forget to first look for more obvious problems like loose or dirty wiring connections. Hope this helps.....if more info needed, email me at seahog@btinternet.com

no a 4.2 engine is in liter's not ccs.

A jack.

please be more specific, but in short - coolant system and coolant used is the same as any other car. rotary's do run hotter than piston engines on generally speaking.

No the engine fluhsing does not ruin the engine.

Cleanliness of diesel & Mobil oil is of the utmost importance. Damage to engine can occur if diesel & Mobil are not properly and completely cleaned. The contamination in the engine can occur from various sources, such as bio degradation of fuel, formation of microbial contents, water presence, More sulphur presence, gum, wax, and sump tank etc.

The flushing need is arises due to black smoke coming out from silencer, increase in fuel consumption, drop in pick up, due to increase in wear & tear of the the engine component etc................

The flushing needs to be done with a proper procedure, whether your vehicle engine is under warranty period or not but this procedure should be carried out in authorized workshop. If the precautions are not taken then the engine failure will take place.

The other way out is to to take the diesel from fuel pump & changing the mobile on time interval recommended by the car manufacturer. In case if the over heating takes place check the viscosity of the mobil and then only use it. In case if there is any hose leakage that will drop the oil level which you can see in the oil indicater then use top up oil or if it has reached changing interval period then change it with new oil.

Perhaps the driver of this 1990 Tracker is referring to the speed in which the torque converter cluch (TCC) blocks up. My 1991 Tracker's TCC is designed to lock-up at 40MPH. This is accomplished by the governor pressure (which is determined by road speed). The TCC relay is under the hood and it sends the signal to the governor pressure switch. When the governor switch closes it energizes the lock-up solenoid valve,which pressurizes the TCC mechanism causing lock-up, which could be mistaken for another shift by some.

Upgrade the intake, exhaust, and fuel injectors.

Bank 1 includes cylinder number 1. Bank 2 is the other side.

Manufacturers like to brag about their fuel injection to sell more boats, so the easiest way is to look for EFI or MPFI on the engine cover. Other than that, fuel injectors are electronic, so they will have extra wires going to them and the sensors that accompany them. A carburetor might have 2 wires going to an electric choke if that.

1.9L SOHC in the SL1, The SL2 has a 1.9L DOHC.

I Get 38mpg from mine.

I've had the same problem. mine was fixed with a couple different steps. 1. Take to ford dealership have them change out fuel pump for free under recall. 2. change the fuel filter myself. 3. change out PCV hose and PCV valve. 4. clean throttle body. 5. use electronic cleaner to clean out MAF sensor. 6. change air filter. This made a huge difference in my car and hopefully helps you

The Windsor Ontario Canada Ford engine plant. Not all 351 windsors were made at this plant

No , the 2.5 liter - 4 cylinder engine in a 1998 Ford Ranger IS NOT an interference

A static load varies slowly, a dynamic load changes with time pretty fast. In order for one to find the answer to this type of structural dynamic question, one might ask the help of a scientist.

1. When the piston rings gets weak the piston take an different agnle for its motion it acuse wear and tear in the cylinder liner and become oval shape there fore the pistor ring can't hold the compression properly

2. Hot spots

3. Back fire

Another answer

I have been a mechanic for 40 years, and the above answer is not correct, Diesels do not backfire, hot spots have nothing to do with Blow by, rings never take a different angle. Not to say that rings cannot wear and loose their knife edge that helps to remove varnish created by oxidized oil on the cylinder walls causing an un even surface and letting compression BLOW BY, as well as carbon acid that is formed in the combustion cycle.

There is a product that can help restore the seal of the rings and stop the wear, I have used Cerma with STM-3 for the last 10 years and it seems to correct the problem with stuck rings due to lacquer build up on the walls of the cylinder. Cerma products have help my business when all other ideas failed, short of a complete rebuild.

3rd try: Ring, cylinder and piston wear if it happened slowly over time. I see quite a few sudden failures now, which is caused by burned or holed pistons. Plan on a complete overhaul.

Hate to disagree with you on the backfire issue. But diesels can backfire. I was in a pit with one that did. Couldn't hear for about an hour. Another one blew a muffler apart. Rare but it can happen. Agree with the rest of your post. Where can you buy Cerma.

yes you can....although after 40hrs looking , I still dont know how
