Reversing Carburetors "Yet another way is to turn thecarburetors round, so that the float chambers are behind the jets, and so come below them when the tail is on the ground, thus cutting off the gasoline low down in the jets.
Some forms of carburetorsare affected more than others by changes of altitude, which explains why the Zenith is so widely employed for airplane engine use.
These instructions apply only to carburetors having air valves and mixture regulating means which are used only in rare instances in airplane work.
Some multiple jet carburetors could be considered as a series of these instruments, each one being designed for certain conditions of engine action.
It is only in recent years that engineers have realized the importance of using carburetors that are efficient and that are so strongly and simply made that there will be little liability of derangement.
All carburetors will require some adjustment in the course of any material change from one level to another.
The tendency of very cold air is to condense gasoline instead of vaporizing it and therefore it is necessary to supply heated air to some carburetors to obtain proper mixtures during cold weather.
This naturally led to the adoption of two carburetors in which each set of cylinders was independently fed by a separate carburetor.
On some six-cylinder aviation engines, two carburetors are used because of trouble experienced with manifolds designed for one carburetor.
Duplex carburetors are necessary to secure the best results from eight- and twelve-cylinder V engines.
The intake manifold for carburetorsare aluminum castings and are so designed that each carburetor feeds three cylinders, thereby insuring easy flow of vapor at all speeds.
Malvin, while capable of running an engine when it was in perfect working order, had no technical knowledge of machinery such as the person who had maliciously "doped" the carburetors must have possessed.
In the bowls of all the carburetorssand had been placed.
An entirely different system adopted at the time of the complete redesign in 1913 consisted of two float-feed Zenith carburetors each feeding a conventional three-outlet manifold.
Most of the descriptions of the new model published at the time it was introduced concentrate on the addition of the two carburetors and the mechanical operation of the inlet valves, but these were only two of many major changes.
The stem upon which the float of some carburetors is mounted is sometimes threaded and provided with a nut by means of which the float may be raised or lowered.
To enable low grades of fuel to be properly vaporized under all running conditions, many carburetorsare provided with a water jacket surrounding the vaporizing chamber.
In addition to this, most carburetors are supplied with an "auxiliary air opening" which serves to furnish the additional air necessary for the mixture at high speeds of the motor.
Other carburetors employ a jacket surrounding the exhaust pipe of the motor and connected with the vaporizing chamber.
Some carburetors are provided with both jacket systems, while others have neither, but whatever design is installed, the best results will be obtained if cold air is used after the motor is once started.
Some carburetors are provided with an adjustment by means of which the "delicacy," or ease of opening, of the auxiliary air valve may be regulated.
During this period of delay, however, the engine for the quarter-size model was completely reconstructed and further tests were made with the experimental engine in developing accessories, such as carburetors and spark coils.
Somewhat more than a dozen carburetors of various forms were constructed before this last type was devised, but this proved so satisfactory that there were never thereafter any carburetor troubles.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "carburetors" in a variety of sentences. We hope that you will now be able to make sentences using this word.
