Onboard computer for status and functional parameters evaluation of internal-combustion engine
Jaroš, David ; Legát, Pavel (referee) ; Kuchta, Radek (advisor)
This thesis deals with design and realization of the onboard computer for evaluating functional parameters and status of the gas engine. Designed solution is consisted of two main parts. The first part is measuring unit whose obtains actual information on engine especially consumption of fuel, rotate per minutes and temperature of engine head. The second part of the solution is formed by pocket computer with appropriate software. The application for the pocket computer processes data from the measuring unit and from GPS receiver, which is integrated in pocket computer. Wireless bluetooth technology is used for data transfer between measuring unit and pocket computer. The application in pocket computer displays and records each of obtained and computed data.
