First Claim
Patent Images
1. An internal combustion engine system having an engine proper forming therein at least first and second combustion chambers, and an exhaust manifold fluidly communicable with the second combustion chamber, said system comprising:
- first intake means for feeding first and second combustion mediums into said first combustion chamber when first and second conditions of said engine take place, respectively;
second intake means for feeding a third combustion medium into said second combustion chamber when said second condition takes place;
reformed gas transmitting means for transmitting a product produced in said first combustion chamber into said second combustion chamber when said first condition takes place;
exhaust means for feeding a product produced in said first combustion chamber into said exhaust manifold when said second condition takes place; and
control means for causing said first and second conditions when lower and higher engine power outputs are required, respectively.

Abstract
When a lower engine power output is required, one of the combustion chambers acts as a reformer operable to convert a mixture of an ordinary fuel and air into a reformed gas which is introduced into the other combustion chambers for the power generating combustion thereof. On the contrary, when a higher engine power output is required, all the combustion chambers are subjected to power generating combustion of a stoichiometric air-fuel mixture.
