An engine device of including: an intake manifold configured to supply air into a cylinder; a gas injector configured to mix fuel gas with air supplied from the intake manifold, and supply mixed gas to the cylinder; an igniter configured to ignite, in the cylinder, premixed fuel obtained by pre-mixing the fuel gas with the air; and a control unit configured to execute a combustion control of a premixed fuel based on the output signal indicative of an output from the engine device. When the air amount is determined to be insufficient and when the output signal is lost, the control unit estimates an output signal based on the fuel gas injection amount from the gas injector, and executes the combustion control based on the estimated output signal.

A system for reducing polluting emissions of diesel engines includes a hydrogen gas generator that mixes the hydrogen gas with diesel fuel during certain operations phases of the engine. A default program mixes no hydrogen gas with the diesel fuel. A first operational program, during a cold start, mixes the hydrogen gas and diesel fuel in a 1:1 ratio. A second operational program, during a stabilization phase, mixes the hydrogen gas and diesel fuel in a 1:3 ratio. A third operational program, during a hot start phase, mixes the hydrogen gas and diesel fuel in a 1:2 ratio.

The present invention provides a catalyst composition for inhibiting the inactivation of a catalyst for purification of compressed natural gas combustion system exhaust gas on which a noble metal component comprising platinum and palladium is supported. An oxidation catalyst, for a compressed natural gas vehicle or static combustion system exhaust gas, in which a first alumina impregnated with platinum, a second alumina impregnated with palladium, and a ceria component are supported on a ceramic support, has a barium cocatalyst supported on the first alumina, thereby greatly inhibiting inactivation of a CNG lean burn engine catalyst.
