How VVTI works?
It is a variable valve timing innovations from toyota, where in power and fuel efficiency can be optimized by varying the timing of the camshaft with respect to the crankshaft of an engine,by retarding or advancing the camshaft by a certain phase angles.A conventional engine has it's camshaft rotate half the crankshaft rotation and the performance of a such engine would be in it's peak efficiency for a single speed only.Engineers developed a technology to overcome this in-efficiencies by introducing variable valve timing where camshaft rotation can advance or retard with respect to the crankshaft,hence optimising performance and fuel efficiency.
How Does Valve Work?
u mean valve of a engine.....? here's the answer... when the crankshaft rotates,then with the help of timing gear the camshaft rotates.timing gears are the gears on crankshaft(pinion) and camshaft(gear). when the cams on the crankshaft rotates it lifts up the follower(during eccentric portion of the cam). follower is connected to a push rod which moves the rocker about a point. rocker presses the valve stem in avalve guide againt the spring pressure. the valve comes down from the valve seat. and our fuel air mixture rushes inside the cylnder. when the non eccentric portion of the cam on the camshaft comes valve stem moves up due to spring pressure. the timing gears are such that they maintain a speed ratio of two between them. it means camshaft has to rotate at half the speed of crankshaft. it is because a valve has to open and close once in every two revolutions of the crankshaft.
What is mechanical actuator?
Mechanism with side camshaft and Mechanism with overhead camshaft both valve actuating mechanisms are used to operate inlet or exhaust valves.
How is a gate valve manufactured?
The gate valve (sometimes known as a sluice valve) is usually manufactured by casting the body, the gate and the bonnet of a suitable material (brass, iron, steel or another alloy) and machining the mating and assembly surfaces, and also the stem. There are a number of different ones made of plastic, too. They are usually injection molded, and because of the precision of the molding process, they generally don't have to machine the parts. Let's look at the metal ones. The body has four critical areas that must be made "to spec" for the valve to make the grade and work well. The primary area is the seat in the middle of the body of the valve. Recall that the gate slides down into the seat area and "wedges" itself in between the two seating surfaces. These are on either side of the gate when it is in the "shut" position. The planes of the seats must not skew, and their angles must be precise. The gate's seats must be comparibly precise. If the gate is to work and seal the fluid path through the valve body, here's where we need precise work. There are the flange areas on either side of the body on the ends where the valve mates to other piping. They are clean and machined for bolting or machined to allow piping to fit snugly into the body where it is welded or brazed. And of course the top of the valve where the bonnet is bolted on or screwed in has to be machined, as well as the operating threads for the stem, which are machined into the body below where the bonnet fits. The bonnet will be machined and have the hole in it for the valve stem. And the packing flange or packing nut will fit on the bonnet to compress the packing that seals the stem. The stem has the operating threads machined on it, and the shaft above is machined smooth so the packing will be effective. With all the parts cast and machined, it's just a matter of putting the thing together. Links are provided to some pictures and drawings.
Why do we use throttle valve in steam engines?
For a steam engine, the steam(throttle) valve that sets the engine speed/power is often known as a regulator. k.Shiva
What is difference between overhead valve engine and overhead cam engine?
Mainly, the difference is that in an overhead cam engine, the camshaft is mounted on the head of the engine, and the valves are still overhead, in an overhead valve engine (sometimes called a "pushrod motor"), the camshaft is in the crankcase.
Which 1 of the following 4 controls the opening of engine's valves is it the Camshaft the Crankshaft the Valve springs or the Combustion chamber?
The camshaft opens the valve via its Lobes, against the valve spring, to open. The valve springs closes the valve back.
What does exhaust?
Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.
Where is the camshaft position sensor located on a 3.0 V6 for Taurus?
2000 SEwhat year do you have, and do you have a 3.0 liter 12 valve engine, or a 3.0 liter 24 valve DOHC engine?12 valve
What does exhaust phasing mean?
Exhaust camshaft phasing on a VVT (variable valve timing) engine is the adjustment of the exhaust camshaft(valve timing) to what the cylinder needs at that rpm/load to improve power/eff. or emissions.
How do you stop an engine valve tap?
Valve taps often occur as a result of a misalignment in the fitting they are in, or a worn out valve seat. In many cases, a new valve spring and cam adjustment will fix the problem, but if it the result of a worn out valve seat, it will have to be machined.
How to replace a camshaft position sensor in a Mercury Sable?
what year, and which engine? Note: if it is newer year, there are two 3.0 liter engines, a 24 valve and a 12 valve. 2000 3.0 liter engine 24 valve
What is the function of the valve guide?
valve guides are present in the engine cylinder head.these valve guide operates the working of valves in the cylinder.that is the inlet ant the outlet valves.
What is the main purpose of a valve spring?
The main purpose of a valve spring is to maintain pressure and ensure that the valves close properly after they have been opened by the camshaft. It helps keep the valves in contact with the camshaft lobes and prevents them from floating or bouncing at high engine speeds. Ultimately, this allows for efficient and precise control of the engine's valve timing and operation.
Where is the camshaft located in a 2007 PT Cruiser?
Top o f the engine, inside the valve cover. . There are two.
Where is the camshaft sensor in a dodge sprinter 2004?
It mounts to the top of the valve cover, under the upper engine cover.
Where is the camshaft in a 91 Ford Explorer?
The camshaft for your 4.0 L - over head valve engine ( OHV ) is inside the engine block , below the intake manifold , going from front to rear in the center of the " V " ( V6 engine ) I hope that makes sense !
