Title: Particulate, method of processing particulate in trap
Inventor: KANESAKA HIROSHI
IPC: F01N3/02
Filed: 1992-10-20
Abstract: PURPOSE:To provide a particulate processing method in a diesel engine which can burn and remove particulate sticking to a trap during running of a vehicle. CONSTITUTION:In a diesel engine incorporating a trap 26 for removing particulate trapped therein, the volume of intake-air into an engine cylinder 1 is decreased by a throttle valve 18, and an exhaust valve 10 is opened in the vicinity of the bottom dead center of the intake stroke of the engine so as to allow counter flow of exhaust gas into the engine cylinder. As a result, the temperature of the exhaust gas rises up. Accordingly, the temperature of the exhaust gas is raised, and accordingly particulate can be burnt and removed during running of a vehicle, without thermally damaging the trap for removing particulate. Thereby it is possible to reduce the manhours and the cost for removing particulate.

Abstract: PURPOSE:To protect the contents of a memory by setting up an electronic apparatus to an OFF mode by software processing when power supply voltage is dropped less than the 1st threshold voltage, and when the voltage is dropped less than the 2nd threshold voltage lower than the 1st threshold voltage and higher than the operation lower limit voltage of a CPU, forcedly resetting the CPU. CONSTITUTION:When the power supply voltage from an operating battery 110 is dropped lower than the 2nd threshold voltage lower than the 1st threshold voltage and higher than the operation lower limit voltage of the CPU 113, the CPU 113 is forcedly reset by hardware. The 1st threshold voltage is set up so that the apparatus is turned to the OFF mode by software processing when the power supply voltage is dropped less than the value. Thereby, the electronic apparatus is to be forcedly turned to the OFF mode when the voltage of the battery 110 is dropped, but even when the forced OFF mode can not be set up because of the runaway state of the CPU 113, the CPU 113 is forcedly reset by a logical circuit 114 when the power supply voltage is less than the 2nd threshold voltage. Consequently, battery consumption can be suppressed and the memory capacity can be prevented from being erased.
