In April 2014, Honda began an upgraded model of Activa with a 125 cc (7.6 cu in) engine and rebranded the model as Activa 125. Currently, both Activa-i and Activa 125 are sold in India along with traditional Honda Activa. Honda began selling the Activa-i in India, a cheaper and lighter version of the Activa, in December 2013.
At room temperature an air gap of 2 to 3 mm can be tolerated without difficulty for a typical target wheel of module m = 2, but in the required temperature range of from −40 °C to 120 °C the maximum gap for effective signal registration drops to 1.3 mm. Smaller pitch target wheels with module m = 1 are often used to get a higher time ...
An electrical circuit then measures this frequency using a digital counter to count the number of cycles in a fixed time period, and displays the number on a digital display as the object's speed. Since this type of speed gun measures the difference in speed between a target and the gun itself, the gun must be stationary in order to give a ...
This was followed by the Chronometric speedometer where the distance traveled was measured over a precise interval of time (Some Smiths speedometers used 3/4 of a second) measured by an escapement. This was transferred to the speedometer pointer. The chronometric speedometer is tolerant of vibration and was used in motorcycles up to the 1970s.
Non contact type TPS work on the principle of Hall effect or inductive sensors, or magnetoresistive technologies, wherein generally the magnet or inductive loop is the dynamic part which is mounted on the butterfly valve throttle spindle/shaft gear and the sensor & signal processing circuit board is mounted within the ETC gear box cover and is ...
An electronic odometer (below speedometer) with digital display showing 91,308 miles (146,946 km) from a Jeep Grand Cherokee (WJ). An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car.
The first tachometer was described by Bryan Donkin in a paper to the Royal Society of Arts in 1810 for which he was awarded the Gold medal of the society. This consisted of a bowl of mercury constructed in such a way that centrifugal force caused the level in a central tube to fall when it rotated and brought down the level in a narrower tube above filled with coloured spirit.
An aeroplane can stall at any speed, so monitoring the ASI alone will not prevent a stall. The critical angle of attack (AOA) determines when an aircraft will stall. For a particular configuration, it is a constant independent of weight, bank angle, temperature, density altitude , and the center of gravity of an aircraft .
