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
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 working the governor during steam turbine operate?
governor senses the speed of spindle of engine and controls the mechanism of opening and closing of throttle valve
What is a make or break engine?
A "make AND break engine" is an engine which controls power/speed by making (enabling) and breaking (disabling) the ignition cycle. In one classic design: One or more large flywheels are attached to the crankshaft. A flyweight governor is also attached to the crankshaft. When the shaft speed slows, the flyweight falls inward, releasing a mechanism which allows the exhaust valve to open. When the piston rises to the cylinder head, the exhaust is pushed out. When the piston pulls back, suction is created. a check valve (one-way valve) in the exhaust closes. That resulting suction opens the intake valve and draw fuel/air mix in. The piston then compresses, ignition occurs, and we get a power stoke. This kicks the crankshaft speed back up. The flyweight pushes out, covering the exhaust valve, and thus blocking further engine cycles. The flywheel, crankshaft, and piston run free, on momentum, until shaft speed slows again, and the process repeats. This is in contrast to most modern engines, which vary speed/power with a throttle, limiting and increasing fuel/air mix, but keeping the ignition cycle active at all times.
How does quadrajet secondary jet air valve work?
As the accelerator is depressed with load on the engine: such as being in gear, engine speed will begin to increase. As the engine begins to require more air and fuel, the secondary air valve will begin to open. These valves are controlled by a choke pulloff vacuum canister which releases as vacuum in the intake drops. Then the suction of the engine will allow your air valves to open also causing fuel to be sucked into the engine through the secondaries. When these valves open, a cam that they are mounted to will lift the secondary metering rods higher out of the jets which allows fuel to pass more readily through the carburetor and into your engine. Cool sound!
An automotive engine's camshaft rotates at what speed?
half the speed of the engine
What is the function of camshaft half engine speed?
The camshaft operates the valves on a 4 cycle engine.
An automotive engine's camshaft rotates?
one half the speed of the crankshaft.
Speed ratio between cam shaft and crank shaft?
Cam spins at half the speed of the engine.
Where are the timing pulleys located in a motor engine?
the timing belt and pulleys driven the cameshaft at half carnk speed(engine speed) pulleys is connected to the crankshft front end of the engine. I donno weather this answer help or not :(
An automotive engines camshaft rotates at?
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
Where is the vehicle speed sensor located on a 1985 Chevrolet celebrity with the 2.5liter engine?
The speed sensor is located on the transaxle on the passenger side of the car. It is near the half shaft.
When a four cylinder engine is operating at 5500 rpm the camshaft is turning at the rate of?
Half the speed of the crankshaft, 2750 rpm.
What is the difference in engine pto and ground pto?
An engine PTO runs off the engine thus the speed is governed by the speed of the engine. A ground PTO is ran from the rotation of the tires. Therefore the speed is governed by the speed of the rotation of the tires.
How does engine computer calculate engine load?
it does it by comparing engine speed to air flow , throttle position , and vehicle speed
What is variable speed governor?
A variable speed governor is an engine part that works with the engine to govern speeds required within the engine. It serves to keep the engine at a steady speed as set by the operator of the vehicle.
What is the purpose of camshaft in the diesel engine?
The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke engine.
