  • Patent number: 4756285
    Abstract: For a combustion procedure for internal combustion engines, in which a fuair mixture with back-fed exhaust gas is introduced into a combustion chamber, a highly-combustible fuel-air mixture without back-fed exhaust gas in introduced into at least one precombustion chamber, which is connected by means of at least one opening with the combustion chamber.
    Type: Grant

  • Patent number: 4700684
    Abstract: The present invention relates to a method for unthrottled load control of an internal combustion engine by means of exhaust gas. The method requires entirely freely adjustable opening and closing times for the inlet and exhaust valves. Starting at full load with the minimum of exhaust gas in the cylinder the amount of exhaust gas in the cylinder is increased thereby reducing the available combustion chamber volume for receiving fresh mixture mass thereby reducing the load. The fresh mixture mass and the exhaust gas mass are controlled exclusively by coordinating the opening and closing times of the intake and exhaust valves.

  • Patent number: 4563982
    Abstract: A method and apparatus for introduction of a fluid or liquid medium into working or operating chamber of an internal combustion engine is disclosed. For the purpose and object of reduction of nitric oxide emission as well as for an improvement of the efficiency there is proposed with a method and apparatus for introduction of the fluid or liquid medium into the working or operating chamber of an internal combustion engine operated with gaseous fuels to admix the fluid continuously or intermittently as to the gaseous fuel and subsequently to blow-in the fuel or power gas/fluid or liquid mixture into the working or operating chamber of the internal combustion engine under the pressure of the fuel or power gas. Hereby there can be utilized or employed advantageously besides the water also alcohol and alcohol/water mixtures, which means media with bound OH-groups.
