Abstract: PURPOSE:To restrain the leak quantity of NH3 by specifying respectively the numerical aperture of a catalyst and a relationship between catalyst capability and engine displacement in the case of reduction and removal of NOx via the addition of NH3 to an exhaust gas and the contact of the exhaust gas with a catalyst of TiO2 system. CONSTITUTION:NOx is reduced and removed by the addition of NH3 to an exhaust gas from a diesel engine and the contact of the exhaust gas with a catalyst of TiO2 system. In this case, the numerical aperture of said catalyst is set at 50%-90%. Also, a relationship between catalyst capability and engine displacement is so set as 1.0

Abstract: PURPOSE:To enable good elimination of NOX in exhaust gas by detecting NOX in exhaust gas, mixing a prescribed amount of NH3 gas based on the detected result and making it in contact with TiO2 catalyst at the prescribed temperature. CONSTITUTION:In driving of a diesel engine, for example, by measuring the generation amount of NOX at the change of engine speed and the change of engine load, NOX in exhaust gas is detected based on the measured result of the engine speed and the engine load, using a previously formed and stored prescribed map. And 0.3-0.9mol of NH3 is mixed, to the detected 1mol of NOX, and TiO2 catalyst is brought in contact with it at the temperature of 250-500 deg.C. By this, efficient deoxidation of NOX can be attempted.

Abstract: PURPOSE:To improve the blowing-up characteristic on start and white smoke by correcting the electronically set fuel injection timing according to the actual combustion state and controlling the injection timing always to an optimum value independently of the deterioration of a fuel injection system. CONSTITUTION:The ignition time signal of an ignition sensor 7 is input into a controller 5. The controller 5 corrects the control signal so that the ignition timing signal accords with the control signal (injection timing) calculated from crank angle, load signal, and the temperature signal and outputs an instruction into an injection timing control mechanism 4. Therefore, the fuel injection timing is controlled to an optimum value under any condition independently of the error in setting an injection pump 2, fuel properties (cetane value), deterioration of a fuel injection valve 8, etc., and the blowing-up characteristic on start and the white smoke can be improved.

Abstract: PURPOSE:To prevent occurrence of cracking at the area located between an intake valve and an exhaust valve, to improve the combustion efficiency of an engine and to reduce the amount of smoke discharged from the engine, by providing a reinforcing member with baffle plates inserted into a cavity in the cylinder head at the position thereof corresponding to the top dead point of a piston. CONSTITUTION:A reinforcing member 6 including baffle plates 5 are fitted in a cylinder head 3. The baffle plates 5 are shaped in an arcuate form and the reinforcing member 6 is disposed in the manner of keeping out of valve seat areas 9 for an intake valve 7 and an exhaust valve 8. Since, with such an arrangement, the opening (h) can be made small, the speed of squish flow S produced near the top dead point of a piston 1 is increased, so that mixing of injected fuel P and air is promoted. Further, since the injected fuel P does not enter into quench area Q and combustion of fuel at the area Q is prevented, production of smoke can be reduced. Further, cracking at the area near the middle portion A between the two valve seat portions 9, 9, caused by the temperature difference at the two portions, can be prevented by the reinforcing member 6.
