Most choke valves in engines are butterfly valves mounted upstream of the carburetor jet to produce a higher partial vacuum, which increases the fuel draw. [ 1 ] In heavy industrial or fluid engineering contexts, including oil and gas production, a choke valve or choke is a particular design of valve with a solid cylinder placed inside another ...
As the airflow through the carburetor increases the reduced manifold vacuum pulls the power valve open, allowing more fuel into the main metering circuit. In a two-stroke engine , the carburetor power valve operates in the opposite manner: in most circumstances the valve allows extra fuel into the engine, then at a certain engine RPM it closes ...
It is one of the three major components for proper engine operation: the computer, electrically controlled carburetor, and the oxygen sensor in the exhaust system. [ 2 ] Starting with the 1986 model year, the AMC straight-4 engines used a throttle body injection (TBI) or single-point , fuel injection system with a new fully computerized engine ...
The choke provision for the Quadrajet was initially in the form of an intake-mounted, heat sensitive spring, (divorced choke), often referred to as a heat riser. The spring connected to a rod that actuated the choke mechanism on the passenger's side of the carburetor, and relied on intake manifold's temperature.
In carburetted engines the lever is called throttle lever and controls the mass flow rate of the air-fuel mixture delivered to the cylinders by the amount of throttle valve opening. In engines with fuel injection system, the lever is typically referred to as power lever and controls the amount of fuel that is injected into the cylinders.
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
A throttle body is somewhat analogous to the carburetor in a non-injected engine, although it is important to remember that a throttle body is not the same thing as a throttle, and that carbureted engines have throttles as well. A throttle body simply supplies a convenient place to mount a throttle in the absence of a carburetor venturi.
HP-150 II (aka HP 45849A) [6] replaced HP-150 in 1984. While still called HP Touchscreen II , the touchscreen was no longer standard, but rather a rarely adopted option. The optional touchscreen bezel was superior to the original bezel, in that the emitters and detectors were now located behind a solid infrared-transparent plastic; thus ...
