How does incorrectly set timing affect fuel consumption?
A stretched timing chain on a DOHC engine will cause a retarded intake camshaft timing and a slightly retarded or normal exhaust camshaft timing. The intake cam will take most of the stretch, leaving the exhaust cam mostly normal. The results of a retarded intake camshaft will be improved fuel economy due to less air-fuel drawn in during the intake stroke. Also, IF the exhaust camshaft is retarded from excessive timing chain stretch the result will be a lower NOX emissions due to exhaust gas being drawn in during the intake stroke, lowering the overall combustion chamber temperature.
How do you set the timing mark on a 2000 Daewoo?
the timing mark on the crank goes down matches with v notch intake and exhaust both go up but be sure you use the intake mark for and exhaust on that gear.
Can you time a engine on the wrong stroke?
With a four stroke engine the ignition timing is set at towards the end of the compression stroke. A novice make make the mistake of setting it at the end of the exhaust stroke. So yes it is possible. However the engine will not run.
Trying to set the set valves on 350 which valve is the intake and which is the exhaust you have found tdc and set the 1 valves now what?
The intake valves line up with the intake runners on the intake manifold. The exhaust valves line up with the exhaust runners on the exhaust manifold or headers. With #1 at tdc you can set 1,2,5,7 intake and 1,3,4,8 exhaust valves. Rotate the engine one revolution to #6 tdc and set the remaining valves.
How do you set the timing on a 1990 dodge spirit?
1) Remove timing belt cover and Valve cover. Remove all spark plugs. 2) Turn crankcase (with socket and ratchet) until #1 piston is at Top Dead Center (A Screwdriver in #1 Spark plug hole will show top) 3) Rotate overhead Cam until intake and exhaust valves are closed over # 1 cylinder. 4) align - intake valve begins to open when piston begins to travel downwards (Intake Stroke). IE: Intake - Compression - Power - Exhaust
Where can you find camshaft timing for 1995 kia sportage 2l dohc?
left one is exhaust and right one intake, set to the cam timing marks, do not forget the crankshaft timing marks too, there are 2 of them also.
How do you increase the horse power in a 1989 camaro RS 5.0?
Change out the exhaust and the air intake and set the timing up with out doing a lot of eng. work
Why does the number one intake valve start to open on your 1997 dodge ram 3.9L engine with the timing gears marks are set right?
The marks on the timing chain gears are not TDC compression. They are TDC exhaust.
You put a 1975 350 in your 1986 half ton and you can not get it to start only fire pops out of the carb what do you do next?
Sounds like it is out of time, check the mark on the crank and number one cylinder and distributor. their is a compression stroke and exhaust stroke so be sure you are one the compression when checking timing. Sounds like it is out of time, check the mark on the crank and number one cylinder and distributor. their is a compression stroke and exhaust stroke so be sure you are one the compression when checking timing. This condition defines a intake valve is open when the spark plug fires. Look to see if the plug wires is properly connected in the right firing order. If the engine has been disassembled the vale timing could not be set proper. Ignition timing may not be set to the right position. Timing mark at TDC. Cylinder number 1 on compression stroke.Drop distributor in with rotor facing cylinder number 1 on distributor cap.
If the timing belt was reset the marks are dead on whats causing your 99 ford escort to turn over but not fire?
you set the base time , now you need to set the static timing.(ignition time) perhaps in the process you disconected a spark plug wire and re attached it in the wrong spot. or when you set the base timing you put the #1 piston on a exhaust stroke rather than the compression stroke. if it was put in exhaust stroke the car is never going to fire up. there could also be other reasons. bad plugs,bad ignition module,bad coil. loose plug wires,bad distributor cap.ect.
What is the timing specs for predator 500?
set the flywheel to T. Intake dots should be a 12 and 9 exhaust 12 and 9 but one tooth advanced (turned clockwise).
How do you set timing on Isuzu NPR 300 and valve setting gap?
To set the timing on an Isuzu NPR 300, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the crankshaft and camshaft gears, and adjust the injection pump timing if necessary using the pump's timing adjustment mechanism. For the valve setting gap, typically, the intake valves should be set to 0.15 mm and the exhaust valves to 0.20 mm when the engine is cold. Always refer to the specific service manual for your model for precise specifications and procedures.
