The result is an engine that fails to maintain idle RPM and frequently stalls. A jammed actuator may be freed simply by cleaning it. However an actuator that has stopped working due to a fault in its servomotor will need replacement. Air leaks in either the stepper housing or pipes will cause elevated idle RPM.
The manual choke pull handle in a 1989 Hyundai Excel. The term "choke" is applied to the carburetor's enrichment device even when it works by a totally different method. Commonly, SU carburettors have "chokes" that work by lowering the fuel jet to a narrower part of the needle. Some others work by introducing an additional fuel route to the ...
However, in a road/commuter bike, the limited power range is a problem. To provide more low RPM power, as well as enable the engine to produce a lot of high RPM power, a power valve system is used. All power valve systems vary the duration of the exhaust port open time, which gives the engine usable low end power combined with excellent top end ...
The Honda CHF50 is a scooter made by Honda and marketed as the Metropolitan in the United States, the Jazz in Canada, the Scoopy in Australia and Asia, and the Crea Scoopy in Japan. Offered in the United States from 2002 to 2009, the Metropolitan was reintroduced in 2013 based on the fuel-injected and air-cooled NCH50 instead of the prior CHF50.
Engines fitted with a decompressor can also be stopped by operating the decompressor, and in a vehicle with a manual transmission it is sometimes possible to stop the engine by engaging a high gear (i.e. 4th, 5th, 6th etc.), with foot brake and parking brake fully applied, and quickly letting out the clutch to slow the engine RPM to a stop ...
At idle speed, the engine generates enough power to run reasonably smoothly and operate its ancillaries (water pump, alternator, and, if equipped, other accessories such as power steering), but usually not enough to perform useful work, such as moving an automobile unless it is set too high. The opposite of idle speed is redline, the maximum ...
Compressor stalls were a common problem on early jet engines with simple aerodynamics and manual or mechanical fuel control units, but they have been virtually eliminated by better design and the use of hydromechanical and electronic control systems such as full authority digital engine control. Modern compressors are carefully designed and ...
Valve float is an adverse condition which can occur at high engine speeds [1] when the poppet valves in an internal combustion engine valvetrain do not properly follow the closure phase of the cam lobe profile. This reduces engine efficiency and performance.
