Design of Thermoelectric Starting Pre-Heater on Gas Fuel

Abstract

This paper presents the results of computer simulation of thermoelectric starting pre-heater on liquefied gas
fuel for easier starting of vehicle engines under low ambient temperatures. The physical model of the heater is
presented, its mathematical description is given, the method and results of calculations of the main energy and
structural characteristics of the device in the software environment "Comsol Multiphysics" are presented.
It is shown that the use of the thermoelectric converter as a source of electric energy provides autonomous
operation of the heater components and allows solving the problem of discharging the vehicle battery during the
operation of the pre-start equipment.
