摘要： PROBLEM TO BE SOLVED: To provide a control technique for a diesel engine capable of suppressing increase in discharge amount of particulate matters such as unburned hydrocarbon and soot by fuel added by an exhaust fuel addition valve, compared to the case where only light oil is used as fuel.
SOLUTION: An ECU 100 sets a minimum operation exhaust temperature that is a lower limit of exhaust gas temperature allowing operation of the exhaust fuel addition valve 88, according to an estimated biofuel concentration. Thus, regardless of the biofuel concentration in fuel, the fuel added by the exhaust fuel addition valve 88 can be sufficiently vaporized by exhaust gas with temperature exceeding the minimum operation allowing exhaust gas temperature set in accordance with the biofuel concentration and can be made flow to an exhaust gas post-processing device 55. The fuel addition from the exhaust fuel addition valve 88 can suppress increase in the discharge amount of particulate matters (PM) such as unburned hydrocarbon (HC) and soot, compared to the case where only light oil is used as fuel.

摘要： PROBLEM TO BE SOLVED: To improve low-temperature startability and to optimize injection form in normal operation in a dual injection type internal combustion engine for FFV. SOLUTION: The dual injection type internal combustion engine for FFV includes: an injector 11 for cylinder injection; and an injector 6 for intake passage injection, wherein alcohol and gasoline can be used as fuel.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of substance such as NOx while suppressing worsening of fuel economy by utilizing favorable characteristic of gas fuel; facilitating leaning and being hard to generate misfire in leaning, in a gas fuel engine. SOLUTION: In this gas fuel engine 1 selecting stratified combustion or homogeneous combustion in accordance with a load region by changing fuel injection time of a fuel injection device, an interval of fuel injection time and ignition time is compensated to prolong mixing time of fuel and air in accordance with a deterioration condition of NOx catalyst 62. Air-fuel ratio in a combustion chamber 8 is leaned, and NOx in exhaust gas is reduced. Since leaning by prolonging mixing time is performed under combustion conditions of large air-fuel ratio (lean) and large throttle opening for stratified combustion, worsening of fuel economy due to high pump loss (intake loss) and high fuel concentration when performing homogeneous combustion is suppressed.
