Fuel and Engines
We commonly relate fuel and engines with gasoline. Other engines also run on natural gas such as propane and “bio-fuels” such as ethanol. The principle remains the same as the fuel induces internal combustion.

sounds like you may have a bad o2 sensor . take to a parts store and they can put there hand held computer on it and they can tell yo if thats it or if you have a differant sencer out . It could also be a bad idle air control valve on the throttle body. It doesn't sound like an o2 sensor problem to me but you never know....
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.

Updated answer,
Firstly the four stages of an "Otto Cycle Engine" are, Induction the intake valve is opening, to let fuel and air mixture into piston chamber. Compression the intake valve and exhaust are shut to compress fuel air mixture. Powerfuel air mixture ignited, both the intake and the exhaust valves are closed. And finally Exhaust when the exhaust valve is open to release spent gasses. At idle speed approximately 800 rpm it should be appreciated timing is important.
What does 805 horsepower equal to in cc?
cc stands for cubic centimeter. It is a measure for volume(as in the space in each cylinder).
horsepower is a measure of the output of the moter. those to things do not convert
What would cause sputtering on an engine?
Needs a full service
Fuel pump/filter
Incorrect fuel
ECU (brain)
AFM/MFA (air fuel mixture meter)
Split air/fuel hoses
What happens during the intake and compression strokes of four stroke engines?
on the intake stoke, the piston is going down to the bottom of the cylinder. As it is going down the intake valve opens and allows a mixture of air and gas in the chamber.
the piston ,once it reaches the bottom of the cylinder,it starts to travel upward(this is the start of the compression stroke) and compresses the air/fuel mixture,and at the same time the intake velve closes,craeting a sealed chamber. As the piston continues to go up it keeps squeezing the air and fuel and just before it tops out the spark-plug fires,igniting this mixture which drives the piston down,starting the power stroke.

Are there any known issues with 38l Ford engines?
They always blow the head gaskets between 70 and 100 thousand miles.
Why does Gas gauge read empty at full and full at empty?
I would assume that the wires are hooked up backwards
have your fuel system purged and cleaned. You can have this done at most shops for around $90
How check fuel pump on 2002 avalanche?
Open the fuel filler door and remove the gas cap. Listen at that location while someone turns on the ignition without starting the engine. You should hear the pump run for a few seconds and then shut down. If you hear nothing then either the fuse is blown or the relay is defective. But even if it does run it may not be pumping any fuel. A fuel pressure test at the fuel rail with a FP gauge will verify if it is pumping. Also a clogged fuel filter will cause the engine to not run.
What size engine does a Saturn SL1 2002 have?
1.9L SOHC in the SL1, The SL2 has a 1.9L DOHC.
I Get 38mpg from mine.
What does it mean to bore over an engine Does boring over provide for any extra performance?
Boring out the cylinders enables you to put larger diameter pistons in the block. Having a larger diameter cylinder means that the displacement of the engine increases. This increase can provide greater horsepower. Boring out a worn-out engine a few thousandths of an inch can square up the bore of the cylinder and breath new life into a worn out engine by restoring its compression. Good compression will have greater effect on improving the performance than the slight gain in displacement.
Who made the 350 Windsor engine?
The Windsor Ontario Canada Ford engine plant. Not all 351 windsors were made at this plant
Why is there a hesitation as you apply the accelerator?
A defective EGR Valve will cause hesitation on acceleration.
How many pounds of pressure is the fuel system under?
Depends on the type of car, usually between about 5 to 85 psi and really depending on the type of car. Racing cars or HO cars have higher psi requirements.
Where can you find the tune up specifications for a 1968 Pontiac Firebird 400 8 cylinder engine?
Call Autozone, Advance Auto, Or Napa. They can order a manual for you. A Haynes manual, or a Chilton. They usually run Under $20
How does engine compression get into the oilpan of a diesel engine?
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.

What is the horsepower for a 3800 sc?
Stock it is 240hp for a 3800 with stock SC. 200hp for a non SC 3800.
How do you install an engine block heater 2004 Chevy trail blazer V6-4.2L?
First check and see if there is a pouch located directly beside your battery. If there is a pouch it will contain a plug that is for the factory engine block heater. If there is no plug then you can pursue an aftermarket type. There are several types. If you want to use a freeze plug block heater, you'll need to have someone help you remove a freeze plug. That usually requires that you remove a lot of the peripheral equipment until you can get a clear access to one of the freeze plugs. Measure the freeze plug then go to an auto parts store and purchase a freeze plug block heater of that specific size. Once you have one that will fit into the hole, you can drill a hole in the freeze plug, then use a prying instrument to remove the old freeze plug. The block heater freeze plug usually goes in with a nut to tighten the freeze plug into the hole. BTW, you'll get a lot of antifreeze all over when you do this, and plan on taking your time since it will be time consuming.
