Abstract

A burner for a vehicle heater of a particle filter regenerator including a combustion air blower, a combustion chamber with a fuel evaporator, a fuel supply with a fuel metering pump by which the fuel is proportionately fed to the evaporator, a glow-plug to ignite a mixture of combustion air and vaporized fuel and a control device, in which the control device switches the flow-plug on to ignite the mixture, starts the fuel metering pump after a first period following the switch-on of the glow-plug and substantially simultaneously with the starting of the fuel metering pump or a second period thereafter initiates a gradual increase in the speed of the combustion gas blower from a standstill or low speed rotation.
