Combustion control method in vehicle engine and engine system for vehicle
22 Jun 20
A combustion control method during a rich spike engine operation includes the steps of: specifying an exhaust gas A/F based on a first output from a NOx sensor on an upstream side of a catalyst; specifying a NOx concentration in the exhaust gas on the upstream side of the catalyst based on a second output from the NOx sensor; and when the A/F is less than a reference range and the NOx concentration is not more than a reference value, calculating a value P1−P0 between a cylinder pressure P1 at EVO during the rich spike operation and that pressure P0 during a normal operation, when P1−P0 is larger than the reference range and P1>P0, a fuel injection timing at a post injection is retarded, when P1−P0 is smaller than the reference range and P1<P0, the timing is advanced.

Particle Counter
10 Jun 20
A particle counter includes a ventilation path, an electric-charge generator that applies the electric charge to a particle in the gas that passes through the ventilation path to obtain a charged particle, a charged-particle-collecting electrode, a heater that is capable of heating the ventilation path, and a controller for performing a particle count detection process, wherein, when the process is performed, the controller obtains a flow rate of the gas on the basis of a calorific value that is supplied to the heater and a difference between the temperature of the gas and the temperature of the surface of the heater, with the heater heating the ventilation path, and obtains the count of the particle per unit volume in the gas on the basis of the flow rate of the gas and a physical quantity that varies depending on an electric charge amount of the charged particle.
