چکیده
Researches into extensometric flowmeter prototype as alternative device used during measurements of air sucked in by piston engine are presented in the paper. The principle of extensometry is based on the variation in resistance of light-gauge metal wire exposed to linear strain. The advantage of designed and made extensometric flowmeter prototype is the unsophisticated design and lack of moving parts, which influences the reliability of the device. The measurements were conducted in static conditions for three different angles of incidence on test stand equipped with Roots blower powered by electric motor. The test stand was capable to generate the flow rate of 0,075 m/s to 0,275 m/s.

In low ambient temperatures the engine will have poor output torque and power generation at the first cycles of its performance, long start time and huge noxious emissions because of insufficient temperature and quality of air-fuel mixture and failure of flame to burn the charge. It is noted that any attempt to increase the charge temperature leads to better combustion conditions. By applying t...
